link of SQL substr blog : http://www.rebellionrider.com/SQL-substr-function.htm SQL substr function SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. Tool used in this tutorial is command prompt. This tutorial series is part of SQL expert exam certification training. if you are preparing for SQL certification you can use my tutorials.

Let's see the Syntax Substr (source_string, start_pos, Substr_length) As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment. Second parameter is Starting position for sub string from the Source string. And the third parameter is Substr_length which is the length for the substring. First two parameters are mandatory to specify while third one is optional. So we can say. SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type. The returning result of SQL Substr function is of same data type of source string. Let's see an example of SQL Substr function. SELECT substr('www.RebellionRider.com',5,14) FROM dual; Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters, Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14. That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length. Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position. Execute it. Here is our result RebellionRider When starting position is larger than the length of source string. In this case SQL Substr function will return NULL as a result. Let's do an example. SELECT substr('www.RebellionRider.com',23,14) FROM dual; As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters Let's execute And the result is Null. Second scenario When the Substr_length is greater than source string In this case the segment return is the substring from starting position to the end of the string. For example SELECT substr('www.RebellionRider.com',5,23) FROM dual; Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22. Execute. As you can see we get a substring from first R of RebellionRider till the end of the source String. Third scenario When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function In this scenario If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function. And if you have supplied Arithmetic expression or a DATE then The Oracle engine first solves or evaluates the Arithmetic expression or the DATE Then casts them as a character. Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character. Let's see some example. SELECT substr(50000-7,2,4) FROM dual; Oracle first evaluates the arithmetic expression that is 50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string. Starting position of substring is 2, that means from the first 9 of 49993 We specified the length of substring is 4 so we must get 9993 as our result. Let's check execute

We have already discussed the intro of SQL character function in Video 10. You can find link of this video in description below. Ok let's go ahead. SQL Concat () function concatenates two separate character string into one character string. Let's see the syntax Concat (string_1 , String_2) Note here that SQL Concat function takes only two arguments at a time. This SQL Concat function will return string_1 concatenated with string_2. This also means that it will return a single string which is a combined string of parameter String_1 and String_2. Both the parameters of SQL Concat function String_1 and string_2 can be of any data-type. You can even specify the columns of the table here. SQL Concat function is equivalent to the concatenation operator (||). SQL concatenation operator is represented by double solid vertical bars or we can say double pipe signs. Question: How to concatenate more than two strings as SQL Concat that can have only 2 parameters and what is the difference between SQL Concat Function and SQL concatenation operator? The one answer for the second Question What is the Difference between SQL Concat Function and SQL concatenation operator? Is While SQL Concat function takes only two parameters, The Concat operator can be repeated as often as is necessary. Meaning, by the help of SQL Concat operator you can combine as many strings as you want. And Concatenation operator is also not supported by several databases such as SQL server so this might cause problem. To answer the first question How to concatenate more than two strings as SQL Concat that can have only 2 parameters? We will have to jump over SQL developer. Let's see some examples. Say we want to retrieve the full name of an employee from Employees table. Let's try it using SQL Concat function. SELECT Concat (first_name, last_name) AS "Full Name" FROM employees; Here in this query we use two column names - first_name and last_name as arguments of our Concat function Execute. As you can see here, we get full name of our employee but there is no space in between first name and last name. We will see how to format this string using SQL Concat function in a few seconds But before that, let's see how to do the same task using SQL concatenation operator. SELECT first_name ||last_name AS "Full name" FROM employees; As you can see this query also produces the same result. Now we will see how to format full name of employees First we will do this using SQL concatenation Operator. SELECT first_name||' '||last_name AS "Full name" FROM employees; Now you can see we get space between first name and last name of the employee. Again, let's do it using SQL Concat function. Here we will see the nested function concept where we will be using nested Concat function to achieve this formatted string. SELECT Concat (Concat (first_name, ' '), last_name) FROM employees; Inner Concat function has two parameters. These are our first column name first_name and an empty string which will be a space between first name and second name. This Concat will now return a string which is the first name with space. This returning string will be the first input of our Outer Concat and column last_name will be the second input. All together this will give us the desired output. As you can see this method is complex than the first one where we use SQL concatenation operator.

Oracle INSTR Function
 
03:28
https://www.databasestar.com/oracle-instr/ The Oracle INSTR function allows you to search a string for the occurrence of another string, and return the position of the occurrence within a string. It’s helpful for finding if a string exists within another string. It can also be used for performing further string manipulation on, like substrings. The syntax of the INSTR function is: INSTR(string, substring [, start_position [, occurrence]]) These parameters are: string: The text string that is searched in. It’s usually the larger of the two strings. Mandatory. substring: The text to search for. It’s usually the smaller of the two strings. Mandatory. start_position: This is an integer value which indicates where in the string value to start the search. Optional, and the default is 1. occurrence: The occurrence of the substring to search for. Optional, and the default is 1, which means the first occurrence. Also, the searches performed by the INSTR function are case-sensitive. The value returned by INSTR is a number value, which is the number in the location of the string where the substring is found. The first character is 1. For more information about the Oracle INSTR function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-instr/

SQL String Functions PART  -- 1
 
17:23
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both). ... The most basic example of a string function is the length(string) function. This function returns the length of a string literal.Scalar-valued UDFs are an easy way to define constant values to use in your database environment. You can pass field values as parameters into UDFs. You can nest scalar function calls. This means that you can pass a call to a scalar-valued function to another function or stored procedure.Numeric functions perform manipulation of numbers that normally are contained in a table column. ... Returns a numeric value, rounded to the specified length or precision. SIGN() SQL server, MySQL, Oracle, PostgreSQL. Returns the positive (+1), zero (0), or negative (-1) sign of a numeric expression.A stored function (also called a user function or user-defined function) is a set of PL/SQL statements you can call by name. Stored functions are very similar to procedures, except that a function returns a value to the environment in which it is called. User functions can be used as part of a SQL expression.Function must return a value but in Stored Procedure it is optional( Procedure can return zero or n values). Functions can have only input parameters for it whereas Procedures can have input/output parameters . ... Functions can be called from Procedure whereas Procedures cannot be called from Function,The CTE was introduced into standard SQL in order to simplify various classes of SQL Queries for which a derived table just wasn't suitable. ... Introduced in SQL Server 2005, the common table expression (CTE) is a temporary named result set that you can reference within a SELECT, INSERT, UPDATE, or DELETE statement.The isDate(string, string) function accepts two string arguments. It takes them, compares the first argument with the second as a pattern and, if the first string can be converted to a date which is valid within system value of locale , according to the specified pattern , the function returns true.printf does the same, treating %s as a pointer-to-string. In C, variables that are arrays become a pointer to the first element of the array when used as function arguments -- so your scanf() sees a pointer to memory (assuming "str1" is an array). SQL - Useful Functions SQL COUNT Function - The SQL COUNT aggregate function is used to count the number of rows in a database table. SQL MAX Function - The SQL MAX aggregate function allows us to select the highest (maximum) value for a certain column. More items... SQL has many built-in functions for performing processing on string or numeric data. Following is the list of all useful SQL built-in functions − SQL COUNT Function - The SQL COUNT aggregate function is used to count the number of rows in a database table. SQL MAX Function - The SQL MAX aggregate function allows us to select the highest (maximum) value for a certain column. SQL MIN Function - The SQL MIN aggregate function allows us to select the lowest (minimum) value for a certain column. SQL - The SQL AVG aggregate function selects the average value for certain table column. SQL SUM Function - The SQL SUM aggregate function allows selecting the total for a numeric column. SQL SQRT Functions - This is used to generate a square root of a given number. SQL RAND Function - This is used to generate a random number using SQL command. SQL CONCAT Function - This is used to concatenate any string inside any SQL command. SQL Numeric Functions - Complete list of SQL functions required to manipulate numbers in SQL. SQL String Functions - Complete list of SQL functions required to manipulate strings in SQL. Returns a Unicode string with the delimiters added to make the input string a valid SQL Server delimited identifier. REPLACE. Replaces a sequence of characters in a string with another set of characters. REPLICATE. Repeats a string value a specified number of times.SQL. Character Functions with Examples. Character functions accept character inputs and can return either characters or number values as output. SQL provides a number of different character datatypes which includes – CHAR, VARCHAR, VARCHAR2, LONG, RAW, and LONG RAW.Aggregate Functions: Aggregates the values and return a single value, below is the list of some aggregate values in sql server. These functions are created by user in the system database, and we have 3 types of user define functions: Scalar Function. Inline Table-Valued Function.

Oracle LISTAGG Function
 
04:57
https://www.databasestar.com/oracle-listagg/ The Oracle LISTAGG function allows you to aggregate or combine string values from multiple rows into a single row. For example, it turns this data: FIRST_NAME Adam Brad Carrie Into this data: FIRST_NAME Adam, Brad, Carrie The same data is shown, but it’s in one row and not multiple. It’s a valuable string manipulation function, and once you know what it is and how it works, you’ll be able to use it in your queries as needed. So what does it look like? The function is: LISTAGG ( measure_expr [, delimiter]) WITHIN GROUP (order_by_clause) [OVER query_partition_clause] These parameters are: measure_expr: This is a column or expression that you want to concatenate the values of. In the example above, it was the first_name column. Mandatory. delimiter: This is the character between each of the measure_expr values. Optional, the default is a comma. order_by_clause: This is the order that the values from the measure_expr are listed. Mandatory. query_partition_clause: This allows you to use LISTAGG as an analytic function, allowing you to show LISTAGG in groups for different rows. One thing to be aware of is that the output of the Oracle LISTAGG function is limited to 4,000 bytes. If you get more than this, you’ll receive an error. The most common way around this that I’ve seen is to write a custom function and use a CLOB. Watch the video to find out more and see some examples.

Oracle CAST Function
 
03:23
https://www.databasestar.com/oracle-cast/ The Oracle CAST function allows you to convert one data type to another. It’s similar to the TO_NUMBER, TO_DATE, and TO_CHAR functions, but allows for more functionality, including converting to many other data types. The syntax of the CAST function is: CAST( {expr | MULTISET (subquery) } AS type_name ) The structure of this function is different to other functions, because it uses the word AS to separate parameters rather than a comma. You can run this function like many other functions, on a single row, which would look like this: CAST( expr AS type_name ) Or, you can run it as though it’s a subquery, using the MULTISET feature: CAST( MULTISET (subquery) AS type_name ) The parameters of the CAST function are: - expr (mandatory choice): This is the value or expression that is to be converted to another data type. - MULTISET (optional): This keyword indicates that the subquery results will return multiple rows, and are then CAST into a collection value. If this is omitted, and the subquery returns multiple rows, it will only return a single row. - subquery (mandatory choice): This is the subquery that can be run to be converted into a collection data type. - type_name (mandatory): This is the Oracle data type that the expr or subquery will be converted to. There are several data types that are compatible with the CAST function, both for converting from and to. You can find the full list in the article mentioned below.

Oracle TO_NUMBER Function
 
02:42
https://www.databasestar.com/oracle-to_number/ The Oracle TO_NUMBER function is used to convert a text value into a number value. It’s similar to TO_CHAR and TO_DATE, but converts a value to a number. The number will also be rounded to a specified number of digits, and returned as a NUMBER value. The syntax is: TO_NUMBER( input_value, [format_mask], [nls_parameter] ) The input_value is the value to be converted to a number. Commonly this is provided as a string (e.g. CHAR or VARCAHR2) but can be several other data types as well. The format_mask is the format that the output value should be displayed as. It must be a valid number format. This is an optional value. The final parameter, nls_date_language, is used to work out how the output is displayed, such as how to display currency symbols. It’s also an optional value.

Oracle LENGTH Function
 
01:23
https://www.databasestar.com/oracle-length/ The Oracle LENGTH function allows you to find the length of a string, also known as the number of characters in a string. It’s a common feature in different languages, and SQL is no different. The LENGTH function only has one parameter: LENGTH ( string_value ) The parameter is the string_value which is the value to check the length of. The function returns a number that represents the number of characters in the function. Some points to remember about the Oracle LENGTH function: If string_value is NULL, then LENGTH will return NULL. If string_value is an empty string, the LENGTH will return NULL. The string_value can be any of the character data types - CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, NCLOB. If the string_value is a CHAR data type, then the LENGTH will include any trailing spaces in the value.

Oracle interview question difference between null functions
 
07:23
Difference between NVL,NVL2, NULLIF and COALESCE NVL function will check whether the first input parameter is null, if first input parameter is null then the function returns the second parameter value as output. NVL2 function will check the first parameter, and return second parameter if the first parameter is not null, otherwise returns third parameter. NULLIF will compare the input parameters ( first and second parameter ), and returns NULL of both are same, otherwise returns the first parameter value. COALESCE, returns the first not null expression in the given input parameters. -------------------------------------------------------------------------------------------------------- List of all the SQL and PLSQL interview questions https://easy-learning-tech.blogspot.com/p/oracle-sql-plsql-interview-questions.html

Oracle COALESCE Function
 
04:00
https://www.databasestar.com/oracle-coalesce/ The COALESCE function in Oracle allows you to input one or many values and return a value that is not NULL. You provide it with a series of values, and it returns the first of thsoe values which are not NULL. The syntax of the Oracle COALESCE function is: COALESCE(expr1, expr2 [, expr_n]) These parameters are: Expr1: the first expression to check for a NULL value. If it’s NULL, the function checks the next parameter. If not, then this value is returned. Expr2: the second expression to check for a NULL value, if the first expression is NULL. If this is NULL, then the next expression is checked, otherwise this value is returned. Expr_n: More expressions can be added and checked in case both expr1 and expr2 are null. Only the first two expressions are needed. The first non-NULL expression is returned. But, if all expressions are NULL, then NULL is returned. One way I’ve recently used this was to find out what phone number to display. A query looked at the mobile number and returned that, but if it was NULL it looked at the home phone and returned that, but if that was NULL it looked to the business phone number. That query looked like this: COALESCE(mobile_phone, home_phone, business_phone) For more information about the Oracle COALESCE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-coalesce/

Oracle RTRIM Function
 
03:27
https://www.databasestar.com/oracle-trim/ The Oracle RTRIM function allows you to remove a specific character from the right side of a string. It’s one of the most commonly used string manipulation functions in SQL, in my experience. The “R” in “RTRIM” stands for “right”. It’s often used to remove spaces from the right of a string. However it can be used to remove other characters, such as trailing slashes from URLs. The syntax for the RTRIM function is: RTRIM(input_string, [trim_character]) The input_string is the text you want to remove characters from. It can be any kind of expression, such as a specific text value or a column. The trim_character is the character you want to remove from the right of the string. It’s an optional parameter, and if you don’t specify it, then a space character is used by the function. The parameters can be any type of string. The function will return either a VARCHAR2 or a LOB data type, depending on the type of data you specify in the parameters. You can specify more than one value for the trim_character, and the RTRIM function will remove both characters from the right of the string. The function is similar to the LTRIM value, where LTRIM removes characters from the left of the string. For more information on the RTRIM function, including the SQL used in this video, read the related article here: https://www.databasestar.com/oracle-trim/

Oracle DECOMPOSE Function
 
01:41
The Oracle DECOMPOSE function is used to transform a string into a Unicode string. It will split a character that has an accent, for example, into two characters. It’s the opposite of the COMPOSE function. The syntax of the DECOMPOSE function is: DECOMPOSE ( input_string [CANONICAL|COMPATIBILITY] ) The parameters of this function are: - input_string is the string that will be decomposed into separate character values in a string. It can be any character data type. - CANONICAL|COMPATIBILITY is an optional parameter and allows you to specify the mode of decomposition. CANONICAL is the default. CANONICAL means it can be re-composed with the COMPOSE function. COMPATIBILITY means that it can’t be re-composed, but it can be useful for katakana characters.

Oracle NVL Function Explained with Examples
 
09:25
https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/ The Oracle NVL function allows you to check a value and return a different value if that value is NULL. It’s great for using another value if the first one is NULL or an optional value, for example people’s phone numbers. It’s also good alongside aggregate functions and grouping so you can see what the difference is between a subtotal row and an actual NULL value. The syntax of the Oracle NVL function is: NVL( check_value, replace_value ) The parameters are: - check_value (mandatory): This is the value that is displayed to the user. It is also the value that is checked for NULL. - replace_value (mandatory): This is the value that appears if the check_value is NULL. The function can use many different data types as parameters: string, date, or numeric. However, both parameters need to be the same type.

Write a sql query to transpose rows to columns. Using PIVOT operator we can very easily transform rows to columns. Select Country, City1, City2, City3 From ( Select Country, City, 'City'+ cast(row_number() over(partition by Country order by Country) as varchar(10)) ColumnSequence from Countries ) Temp pivot ( max(City) for ColumnSequence in (City1, City2, City3) ) Piv

DYNAMIC SQL WITH EXECUTE IMMEDIATE IN ORACLE PL/SQL WITH EXAMPLE
 
21:53
The audio and video now synced. Ever tried creating a table inside a PL SQL block, or a function or a procedure? If yes, then you would know that it would raise an error, as DDL statements are not allowed inside a PL/SQL Block. So the solution to such a case, where you want to generate tables, or sequences or want to execute any DDL statement on the fly, then use synamic sql. Dynamic SQL statment will allow you to create state statements on the fly and then you can execute them using the execute immediate statement. This video tutorial demonstrates on this topic of using synamic sql with execute immediate in a PL/SQL block.

Oracle TO_TIMESTAMP Function
 
01:31
https://www.databasestar.com/oracle-to_timestamp/ The Oracle TO_TIMESTAMP function can be confusing, but we’ll explain it in this video. This function allows you to convert a string value into a TIMESTAMP value. A TIMESTAMP value is a type of DATE, but has a few components: - A date, including day, month, and year - A time, including hours, minutes, seconds, and fractional seconds This is a useful data type because it allows you to store a time down to fractions of a second. The syntax of the TO_TIMESTAMP function is: TO_TIMESTAMP ( input_string [, format_mask] [, nls_param] ) The input_string parameter is the string you want to convert. The format_mask is where you specify the format of the input_string parameter. This is so you can specify the input_string in a variety of formats, and just use this format_mask to indicate which format it is in. The nls_param parameter is another optional parameter, and allows you to specify the returning language of the month and day names. The default format will depend on the region you’re running your database in. In my example (using Oracle Express in Australia), the default format is ‘DD-MM-RRRR HH:MI:SS AM’.

ASCII Function in SQL Query with Example
 
01:33
ASCII(): ASCII function returns the NUMBER code that represents the specified character. Sytax: ASCII( single_character ) PARAMETERS: single_character is the specified character to retrieve the NUMBER code for. If more than one character is entered, the ASCII function will return the value for the first character and ignore all of the characters after the first. Let's look at some Oracle ASCII function examples and explore how you would use the ASCII function in Oracle/PLSQL. For example: ASCII('C') would return 67 ASCII('T') would return 84 ASCII('T2') would also return 84 Thanks for watching...:)
