SQL Tutorial - 21: The UPDATE Query
In this tutorial we'll check out the UPDATE Query which is used to update/change records in a table.
Views: 80517 The Bad Tutorials
This video demonstrates how user can update data of a particular table(t1), based on the join condition with other table(t2). So it would be a easy way to ditch the for-loop, and check for the condition every time. What was to be achieved from the for-loop can be achieved with a single simple update statement. A simple trick to update data in table based on some conditional data in some another table, would help you to increase the performance of your code massively. For ex : UPDATE TABLE1 t1 SET COL1 = (SELECT COL FROM TABLE2 t2 where t1.col = t2.col);

SQL with Oracle 10g XE - Using UPDATE to Change Data in a Table
In this video I use the UPDATE command to change existing data within a table. When using the UPDATE command you also need to use the keyword SET to choose the field column you wish to change and also a WHERE statement to choose the individual record that needs changed. The command I used is: UPDATE BOOKS SET BINDING = 'P' WHERE BOOK_ID = '11'; This video is part of a series of videos with the purpose of learning the SQL language.

Merge Statement in Oracle SQL with Example (UPDATE/DELETE or INSERT)
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!!!

How To Insert,update,delete,join Data into a Table Using SQL Developer tool
How To Insert,update,delete,join Data into a Table Using SQL Developer tool In this topic, you learn to add objects to the Query Builder interface and then create a query based on those objects. In this section, you create a query based on the EMPLOYEES and DEPARTMENTS tables. You will generate output that shows per department name, the employees who work in that department. Perform the following steps to add the EMPLOYEES table to the Query Builder. 1 . Select the Query Builder tab to open Query Builder window. 2 . Drag and drop the EMPLOYEES table from the Connections navigator to the Query Builder window. 3 . Drag and drop the DEPARTMENTS table object over to the Query Builder window, so that the two table objects are displayed in the Query Builder window. Because there are two relationships defined between the EMPLOYEES and DEPARTMENTS tables, you see two lines between the tables identifying the columns that are linked together through foreign key constraints. The two relationships are defined as: The MANAGER_ID in the DEPARTMENTS table must be a value of the EMPLOYEE_ID in the EMPLOYEES table (managers must exist as employees). The DEPARTMENT_ID in the EMPLOYEES table must be a value of the DEPARTMENT_ID in the DEPARTMENTS table (an employee's department must exist in the DEPARTMENTS table, or be null). 4 . Next, you select the columns that you want to see in the report. In the EMPLOYEES table, check the FIRST_NAME, LAST_NAME, JOB_ID, SALARY, and DEPARTMENT_ID columns. As you select these columns, note that they are added in the order that you select them into the window below the table objects. In the DEPARTMENTS table, check the DEPARTMENT_NAME column. 5 . Click Run .

Learn How to Update Data Rows using Update Statement in SQL
Learn about using UPDATE statement in SQL. As the name suggests UPDATE statement is used to update the data rows in a table. The UPDATE statement can update one or multiple column values in single SQL statement. WHERE clause is used to specify the data row to be updated. UPDATE statement without WHERE clause will update all the data rows in the table. Any existing data rows or records in target table remain unaffected. Here are the examples UPDATE statements, UPDATE tablename SET column1 = newvalue; UPDATE tablename SET column1 = newvalue1, column2 = newvalue2 WHERE columnid = 3; Select the "school" database, "USE school;" Run a simple SQL statement to display all the data rows in students table using SQL statement, "SELECT * FROM students;" Here in this result set, take a look at studentid 1. Suppose we have accidentally added this student record under class first instead of second. And now we are going to update this row to change the class value from 'First' to 'Second'. We will use the SQL statement, "UPDATE students SET class = 'Second' WHERE studentid = 1;" Press enter to execute the statement and display all the data rows in 'students' table, "SELECT * FROM students;" And sure enough the class value for studentid 1 is changed from 'First' to 'Second'.

SQL Tutorial 4:  Use ALTER , UPDATE, DELETE, and DROP statements
How do you ALTER, UPDATE, DELETE, DROP table in a database? A standard SQL scripts are applicable to all database vendors such as Informix, SQL Server, Oracle, MySQL when employing this command including DB2. The video explains how to ALTER table. Alter command is used when you add or DROP column/s in a table. Make sure you execute REORG TABLE after the alteration. When changes are required to a row data, execute the UPDATE SET command. WHERE clause must be included to isolate records that fall on the criterion. Failure to do so will update the entire column of that table if done carelessly. WHERE clause is also used when executing a DELETE sql script. If you fail to include WHERE clause, the entire rows in the table will be deleted. Execute with caution when working with DROP command. On most cases, the changes are irreversible when you are done executing this command. You may DROP column, table, views, stored procedure, user defined functions, database or simply combined it with ALTER command.

SQL: Delete Vs Truncate Vs Drop
In this tutorial, you'll learn the difference between delete/drop and truncate. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. 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. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

Oracle SQL Tutorial 19 - ON DELETE (SET NULL and CASCADE)
Welcome everyone! Something you need to consider when you are creating foreign keys is what happens if you delete the parent? As a reminder, the parent is the row that has the value you are referencing in the row that has a foreign key. Why is this something important to consider? It's important because foreign keys need to protect us from two primary things, unacceptable INSERT statements, and unacceptable DELETE statements. Let's see what happens when we try to insert incorrect data into the table with the foreign key: INSERT INTO projects VALUES (1, 'Update website homepage', 'CalebCurry') The response tells us plainly that there is no such user in the users table. So this works correctly. Deleting data on the other hand works a bit differently because the database does not know what you want to do with the child row when you delete the parent from the parent table. By default, we will get an error message that prevents the parent from being deleted, but there are some other options. How do we configure this? This is where the ON DELETE statement comes in. We add the keywords ON DELETE right after the foreign key and then we can give it the option of CASCADE or SET NULL. CASCADE means that if we delete the parent, we are also going to delete the child. In our situation what that means is that if somebody creates a project in our project table and then that persons account gets deleted, all of the projects he owns will also be deleted. CASCADE: CREATE TABLE projects( project_id NUMBER, Project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL, CONSTRAINT projects_pk PRIMARY KEY (project_id), CONSTRAINT projects_users_fk FOREIGN KEY (creator) REFERENCES users (username) ON DELETE CASCADE ) SET NULL will take the value in the child table and get rid of it. What you are left with is NULL. This means that we have an orphaned child. The first thought you might have is that it is a bad thing to have an orphaned child, but in databases that is not always so. In our application if we had it set to SET NULL, when a user account gets deleted the projects would remain in existence they would just lack a creator. This might be a good thing if you are concerned about the long term survival of a project, this might be the route you want to go. It ultimately depends on the application purpose. If you don't like CASCADE or SET NULL, you can leave the entire ON DELETE statement and just have Oracle throw an error when a parent is deleted. As for us, we are going to use ON DELETE CASCADE. We need to use this with extreme caution. If you are not careful, someday you will run a delete a row and that will cascade through you database deleting a bunch of stuff you didn't want to delete. Stuff happens, so make sure you back up your database every once in eternity. Now, in the last video we started with a database design that had three tables. We've only created two in this video. In the next video we are going to create the next one, which is a little special.
