Merge Statement in Oracle SQL with Example (UPDATE/DELETE or INSERT)
 
15:04
This video demonstrates how to write a Merge Statement in oracle sql, how it is useful in doing a conditional update or delete or both of them when the condition between the target table and source table is evaluated to true, and how we can insert the record into the target table when condition is evaluated to false. The video also shows the use of UPDATE, DELETE and INSERT with Merge, and also the various possible ways to use a Merge statement!!!

SQL with Oracle 10g XE - Using INSERT to Add Data to a Table
 
06:20
In this video I use the INSERT command to add an entire record into a table. When using the command you must also use the keyword VALUES. If you want to enter a null value (one that has no value) for a field you can use the keyword NULL. Be sure to put single quotes around data types that are not numbers. Values need to be entered in the order the fields appear in the table. The commands I used are: INSERT INTO BOOKS VALUES (1,'140231862','9780140231861','The Winter King: A Novel of Arthur','Fiction','14.99','P',1996,1,2) INSERT INTO BOOKS VALUES ('2','140232478','9780140232479','Enemy of God: A Novel of Arthor','Fiction',14.99,'P','1997',1,2); INSERT INTO BOOKS VALUES ('3','140232877','9780140232875','Excalibur: A Novel of Arthor','Fiction',14.99,'P','1998',1,2); INSERT INTO BOOKS VALUES ('4','6513840','9780006513841','Harlequin: Grail Quest','Fiction',19.99,'P','2001',1,1); INSERT INTO BOOKS VALUES ('5','6513859','9780006513858','Vagabond: Grail Quest','Fiction',19.99,'P','2003',1,1); INSERT INTO BOOKS VALUES ('6','7149891','9780007149896','Heretic: Grail Quest','Fiction',19.99,'P','2004',1,1); INSERT INTO BOOKS VALUES ('7','553103547','9780553103540','A Game of Thrones','Fiction',13.99,'H','1996',2,4); INSERT INTO BOOKS VALUES ('8','553801473','9780553801477','A Dance with Dragons','Fiction',13.99,'H','2010',2,5); INSERT INTO BOOKS VALUES ('9','055357342X','9780553573428','A Storm of Swords','Fiction',4.99,'P','2003',2,4); INSERT INTO BOOKS VALUES ('10','1596590424','9781596590427','50 Success Classics','Audio',17.99,NULL,NULL,3,3) INSERT INTO AUTHOR VALUES (1,'Cornwell','Bernard'); INSERT INTO AUTHOR VALUES (2,'Martin','George'); INSERT INTO AUTHOR VALUES (3,'Butler','Tom'); INSERT INTO PUBLISHER VALUES (1,'HarperCollins Publishers Canada, Limited'); INSERT INTO PUBLISHER VALUES (2,'Penguin Books Canada, Limited'); INSERT INTO PUBLISHER VALUES (3,'Gildan Media Corp'); INSERT INTO PUBLISHER VALUES (4,'Bantam Dell Pub Group'); INSERT INTO PUBLISHER VALUES (5,'Spectra'); This video is part of a series of videos with the purpose of learning the SQL language.

PL SQL Tutorials for Beginners | IF THEN ELSE Conditions
 
08:44
PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. The IF-THEN-ELSIF statement allows you to choose between several alternatives. An IF-THEN statement can be followed by an optional ELSIF...ELSE statement. The ELSIF clause lets you add additional conditions. When using IF-THEN-ELSIF statements there are few points to keep in mind. It's ELSIF, not ELSEIF An IF-THEN statement can have zero or one ELSE's and it must come after any ELSIF's. An IF-THEN statement can have zero to many ELSIF's and they must come before the ELSE. Once an ELSIF succeeds, none of the remaining ELSIF's or ELSE's will be tested. Subscribe to our Channel for more videos https://www.youtube.com/channel/UC7sbHUgN8FnJEZkEjvKTwJg

B)NOT NULL CONSTRAINT: Not null constraint restrict from inserting null values. If we want some columns does not take null values then we can use this constraint. C)CHECK CONSTRAINT: A check constraint allows you to specify a condition on particular column in a table. we can add our custom logical conditions.

SQL Into - How to Copy Table Data with Select Into Statement - SQL Training Online
 
05:08
http://www.sqltrainingonline.com SQL Into - How to Copy Table Data with Select Into Statement - SQL Training Online In this video, I show you how to copy data using the SQL INTO statement. Including a trick to copy only a table schema in SQL Server. How do you copy a whole table in SQL Server? You often see the SQL INTO statement when you are using INSERT, but there is a special INTO statement in SQL Server that is used with the SELECT statement that allows you to make a copy of a table for development, testing, or whatever purpose you can think of. So, to start, let's take a look at the SQL Training Online Simple DB employee table. You can see that we have 14 records Now, all we have to do to make a copy of the table is to simply add the SQL INTO clause: SELECT * INTO EMPLOYEE_TEST FROM EMPLOYEE If we run that, you see that we made a copy of the table with all of the data. Now, I want to go ahead and empty the employee_test table and show you how to use the INSERT INTO. If you already have a copy of the table, (I will show you a shortcut in a minute on how to create a copy without data.) then you can use the following insert into statement: INSERT INTO EMPLOYEE_TEST SELECT * FROM EMPLOYEE After running that statement, you see that I have inserted data from the Employee table into the employee_test table. This is sometimes referred to as INSERT INTO SELECT. But, there is one trick that I have used throughout the years that is pretty cool. Sometimes, you want the table schema, but you don't want the data. Now, I know that you can use Management Studio to script out the table for you, but there is an easier way that is more flexible as far as I am concerned. That is to use the SELECT INTO FROM, but put the following in the WHERE clause: SELECT * INTO EMPLOYEE_TEST FROM EMPLOYEE WHERE 1=2 The 1=2 makes is so not data will come over, but you get the new table with the right column types. Is that pretty cool? I have found many uses for this over the years. Let me know what you think bellow.

SQL Statement - Merge and Case statement
 
09:34
Merge statement introduced in SQL Server 2008 allows us to perform Inserts, Updates and Deletes in one statement. This means we no longer have to use multiple statements for performing Insert, Update and Delete. With merge statement we require 2 tables Case Statement .The CASE function lets you evaluate conditions and return a value when the first condition is met (like an IF-THEN-ELSE statement).

7. Compile-time warnings help avoid "WHEN OTHERS THEN NULL".
 
03:23
One of Tom Kyte's favorite pet peeves, the following exception sections "swallow up" errors. EXCEPTION WHEN OTHERS THEN NULL; EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE (SQLERRM); In fact, any exception handler that does not re-raise the same exception or another, runs the risk of hiding errors from the calling subprogram, your users, and yourself as you debug your code. Generally, you should log the error, then re-raise it. There are certainly some cases in which this advice does not hold (for example: a function that fetches a single row for a primary key. If there is no row for the key, it's not an application error, so just return NULL). In those cases, include a comment so that the person maintaining your code in the distant future knows that you weren't simply ignoring the Wisdom of the Kyte. Example: EXCEPTION WHEN OTHERS THEN /* No company or this ID, let calling subprogram decide what to do */ RETURN NULL; One way to avoid this problem is to turn on compile-time warnings. Then when your program unit is compiled, you will be warned if the compiler has identified an exception handler that does not contain a RAISE statement or a call to RAISE_APPLICATION_ERROR.

oracle interview question - What is SQL, What are the types of SQL statements
 
09:16
List of all the SQL and PLSQL interview questions @ https://easy-learning-tech.blogspot.com/p/oracle-sql-plsql-interview-questions.html ----------------------------------------------------------------------------------------------------------- SQL stands for Structured query language, In simpler terms it’s the way to communicate with the database, what I mean by communication here is , any instruction we want to give to database would be through SQL. So, these instructions are nothing but commands or statements in SQL. For instance, if you want to store some new data into database, then you need to use "INSERT" statement. similarly if you want to remove some data, then you need to use "DELETE" statement. Depends on the functionality of these instructions or statements, the SQL statements are broadly classified into five sub categories, or five SUB SQL languages as given below, DDL ( Data Definition Language ) DML ( Data manipulation Language ) DCL ( Data Control language ) TCL ( Transaction Control Language ) DRL ( Data Retrieval Language ) These language are classified based on the core functionality they perform, Given below commands for each language. DDL – CREATE, ALTER, DROP, TRUNCATE DML – INSERT, UPDATE, DELETE DCL – GRANT, REVOKE TCL – COMMIT, ROLLBACK, SAVEPOINT DRL – SELECT

There are several ways of finding the nth highest salary. By the end of this video, we will be able to answer all the following questions as well. How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) GO To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3

DECODE and CASE in Oracle
 
02:00
DECODE and CASE statements in Oracle both provide a conditional construct. Databases before Oracle 8.1.6 had only the DECODE function. CASE was introduced in Oracle 8.1.6 as a standard, more meaningful and more powerful function. Everything DECODE can do, CASE can. There is a lot else CASE can do though, which DECODE cannot. DECODE performs an equality check only. CASE is capable of other logical comparisons such as != etc. It takes some complex coding – forcing ranges of data into discrete form – to achieve the same effect with DECODE. An example of putting employees in grade brackets based on their salaries. This can be done elegantly with CASE. Follow the steps given in video : https://youtu.be/QPxKAufB_eo and Learn How to use DECODE and CASE in oracle

In our upcoming videos we will discuss writing a generic handler that calls this stored procedure. The generic handler will convert the data to JSON format. The JSON formatted data can then be consumed by the jQuery datatables plugin. All the processing, that is, paging, sorting and searching is done on the server side. If the dataset is small you can retrieve all the data at once and all the processing (i.e paging, searching, sorting) can be done on the client-side. We discussed this in Part 106 for jQuery tutorial. However, if the dataset is large (i.e if you have millions of records), loading all data at once is not the best thing to do from a performance standpoint. With large dataset, we only want to load the correct set of rows (sorted, paged and filtered data ) that want to display on the page. So all the processing ((i.e paging, searching and sorting) should be done by the server. So in this and our upcoming videos we will discuss performing server side processing. SQL Script to create the table and populate it with test data Create table tblEmployees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(20), JobTitle nvarchar(20) ) Go Insert into tblEmployees values('Mark', 'Hastings','Male','Developer') Insert into tblEmployees values('Maria', 'Nicholas','Female','Developer') Insert into tblEmployees values('Robert', 'Stephenson','Male','Sr. Developer') Insert into tblEmployees values('Mary', 'Quant','Female','Sr. Developer') Insert into tblEmployees values('John', 'Stenson','Male','Sr. Developer') Insert into tblEmployees values('Gilbert', 'Sullivan','Male','Developer') Insert into tblEmployees values('Rob', 'Gerald','Male','Sr. Developer') Insert into tblEmployees values('Ron', 'Simpson','Male','Developer') Insert into tblEmployees values('Sara', 'Solomon','Female','Sr. Developer') Insert into tblEmployees values('Rad', 'Wicht','Male','Sr. Developer') Insert into tblEmployees values('Julian', 'John','Male','Developer') Insert into tblEmployees values('James', 'Bynes','Male','Sr. Developer') Insert into tblEmployees values('Mary', 'Ward','Female','Developer') Insert into tblEmployees values('Michael', 'Niron','Male','Sr. Developer') SQL Server stored procedure paging sorting and searching create proc spGetEmployees @DisplayLength int, @DisplayStart int, @SortCol int, @SortDir nvarchar(10), @Search nvarchar(255) = NULL as begin Declare @FirstRec int, @LastRec int Set @FirstRec = @DisplayStart; Set @LastRec = @DisplayStart + @DisplayLength; With CTE_Employees as ( Select ROW_NUMBER() over (order by case when (@SortCol = 0 and @SortDir='asc') then Id end asc, case when (@SortCol = 0 and @SortDir='desc') then Id end desc, case when (@SortCol = 1 and @SortDir='asc') then FirstName end asc, case when (@SortCol = 1 and @SortDir='desc') then FirstName end desc, case when (@SortCol = 2 and @SortDir='asc') then LastName end asc, case when (@SortCol = 2 and @SortDir='desc') then LastName end desc, case when (@SortCol = 3 and @SortDir='asc') then Gender end asc, case when (@SortCol = 3 and @SortDir='desc') then Gender end desc, case when (@SortCol = 4 and @SortDir='asc') then JobTitle end asc, case when (@SortCol = 4 and @SortDir='desc') then JobTitle end desc ) as RowNum, COUNT(*) over() as TotalCount, Id, FirstName, LastName, Gender, JobTitle from tblEmployees where (@Search IS NULL Or Id like '%' + @Search + '%' Or FirstName like '%' + @Search + '%' Or LastName like '%' + @Search + '%' Or Gender like '%' + @Search + '%' Or JobTitle like '%' + @Search + '%') ) Select * from CTE_Employees where RowNum ] @FirstRec and RowNum [= @LastRec end Finally test the stored procedure

Part 12   Can we join two tables without primary foreign key relation
 
10:38
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/09/part-12-can-we-join-two-tables-without.html Can we join two tables without primary foreign key relation Yes, we can join two tables without primary foreign key relation as long as the column values involved in the join can be converted to one type. ID column in Departments table is not the primary Key and DepartmentId column in Employees table is not the foreign key. But we can still join these tables using ID column from Departments table and DepartmentId column from Employees table, as both the columns involved in the join have same data type i.e int. Select Employees.Name as EmployeeName, Departments.Name as DepartmentName from Employees join Departments on Departments.ID = Employees.DepartmentId The obious next question is, if primary foreign key relation is not mandatory for 2 tables to be joined then what is the use of these keys? Primary key enforces uniqueness of values over one or more columns. Since ID is not a primary key in Departments table, 2 or more departments may end up having same ID value, which makes it impossible to distinguish between them based on the ID column value. Foreign key enforces referential integrity. Without foreign key constraint on DepartmentId column in Employees table, it is possible to insert a row into Employees table with a value for DepartmentId column that does not exist in Departments table. The following insert statement, successfully inserts a new Employee into Employees table whose DepartmentId is 100. But we don't have a department with ID = 100 in Departments table. This means this employee row is an orphan row, and the referential integrity is lost as result Insert into Employees values (8, 'Mary', 'Female', 80000, 100) If we have had a foreign key constraint on DepartmentId column in Employees table, the following insert statement would have failed with the following error. Msg 547, Level 16, State 0, Line 1 The INSERT statement conflicted with the FOREIGN KEY constraint. The conflict occurred in database "Sample", table "dbo.Departments", column 'ID'.

Update and Insert data in database from datagridview
 
07:27
Connect with me On LinkedIn: https://www.linkedin.com/in/bhubanshrestha Sometime user needs to update large amount of data in such case updating data from datagrid view is good choice because user gets all information in a row format. In this video tutorial you will learn how to update database table from datagrid view. You can insert, upadate and delete data of database from datagrid view. In this video tutorial deleting is not shown but it is very simple. Just select row then update. NOTE You have to include primary key column in data grid view. If you want to hide primary key column to user then you can achieve this by datagridview1.Columns[0].Visible=false ;//0 is the index of primary key column OR datagridview1.Columns["PrimaryKey"].Visible=false; //PrimaryKey is a column header text of primary key.

It is very difficult to find failed queries executed by Entity Framework. Use following plsql trigger to find quries CREATE TABLE QUERY_LOG ( ID NUMBER, ORA_ERR VARCHAR2(10), EXE_DATE DATE, QRY_LOG NCLOB) / CREATE SEQUENCE QUERY_LOG_ID NOCACHE / CREATE OR REPLACE TRIGGER Failed_To_Extend_Temp AFTER SERVERERROR ON DATABASE DECLARE l_sql_text ora_name_list_t; l_n NUMBER; t1 NCLOB; BEGIN --IF (is_servererror(942) ) THEN l_n := ora_sql_txt(l_sql_text ); FOR I IN 1 .. l_n LOOP t1 := t1||l_sql_text(i); END LOOP; INSERT INTO QUERY_LOG (Id , Ora_Err , EXE_DATE , QRY_LOG) VALUES (QUERY_LOG_ID.Nextval, ora_server_error(1), Sysdate,t1 ); --END IF; END; /

Part 2   SQL query to get organization hierarchy

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/05/part-2-sql-query-to-get-organization.html To get the best out of this video, the following concepts need to be understood first. These are already discussed in SQL Server Tutorial. 1. Self-Join - http://www.youtube.com/watch?v=qnYSN_7qwgg 2. CTE - http://www.youtube.com/watch?v=ZXB5b-7HJHk 3. Recursive CTE - http://www.youtube.com/watch?v=GGoV0wTMCg0 Here is the problem definition: 1. Employees table contains the following columns a) EmployeeId, b) EmployeeName c) ManagerId 2. If an EmployeeId is passed, the query should list down the entire organization hierarchy i.e who is the manager of the EmployeeId passed and who is managers manager and so on till full hierarchy is listed. For example, Scenario 1: If we pass David's EmployeeId to the query, then it should display the organization hierarchy starting from David. Scenario 2: If we pass Lara's EmployeeId to the query, then it should display the organization hierarchy starting from Lara. We will be Employees table for this demo. SQL to create and populate Employees table with test data Create table Employees ( EmployeeID int primary key identity, EmployeeName nvarchar(50), ManagerID int foreign key references Employees(EmployeeID) ) GO Insert into Employees values ('John', NULL) Insert into Employees values ('Mark', NULL) Insert into Employees values ('Steve', NULL) Insert into Employees values ('Tom', NULL) Insert into Employees values ('Lara', NULL) Insert into Employees values ('Simon', NULL) Insert into Employees values ('David', NULL) Insert into Employees values ('Ben', NULL) Insert into Employees values ('Stacy', NULL) Insert into Employees values ('Sam', NULL) GO Update Employees Set ManagerID = 8 Where EmployeeName IN ('Mark', 'Steve', 'Lara') Update Employees Set ManagerID = 2 Where EmployeeName IN ('Stacy', 'Simon') Update Employees Set ManagerID = 3 Where EmployeeName IN ('Tom') Update Employees Set ManagerID = 5 Where EmployeeName IN ('John', 'Sam') Update Employees Set ManagerID = 4 Where EmployeeName IN ('David') GO Here is the SQL that does the job Declare @ID int ; Set @ID = 7; WITH EmployeeCTE AS ( Select EmployeeId, EmployeeName, ManagerID From Employees Where EmployeeId = @ID UNION ALL Select Employees.EmployeeId , Employees.EmployeeName, Employees.ManagerID From Employees JOIN EmployeeCTE ON Employees.EmployeeId = EmployeeCTE.ManagerID ) Select E1.EmployeeName, ISNULL(E2.EmployeeName, 'No Boss') as ManagerName From EmployeeCTE E1 LEFT Join EmployeeCTE E2 ON E1.ManagerID = E2.EmployeeId

Performing logical deletes in Oracle ADF
 
09:26
Hi, In some use cases it is required not to physically delete the row from database but instead update a FLAG e.g delete_FLAG = 'Y' in order to hide rows from user. So, if you don't familiar with the framework then you might take a long route to do the task which could easily be done by declarative steps. In this video we will do the following. 1. We will add history columns in entities. 2. we will have a view criteria to display only DELETE_FLAG = 'N' rows. 3. On deletion in detail table we will delete logically. 4. We will update the History columns of Master entity as modified by and modified_date.

jQuery datatables get data from database table

There are many ways to get data into DataTables. If the data is small you can retrieve all the data at once and the processing (i.e paging, searching, ordering) is done on the client-side. On the other hand if the database data is large, server-side processing can be enabled. With server-side processing enabled, all paging, searching, ordering actions that DataTables performs are handed off to the server. In this video we will discuss retrieving all the data at once. The datatables plugin performs all the processing (i.e paging, searching, ordering etc) on the client-side. We want to retrieve data from the following database table tblEmployee. The database data should then be displayed using jQuery datatables plugin
