PL/SQL: Mutating Triggers Part-1
 
06:24
In this tutorial, you'll learn... 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.

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

What is a Trigger : A trigger is a special kind of a store procedure that executes in response to certain action on the table like insertion, deletion or updation of data. It is a database object which is bound to a table and is executed automatically. Types Of Triggers 1. After Triggers (For Triggers) : After Insert, After Update, After Delete 2. Instead Of Triggers CREATE TABLE tblemployee(Emp_ID INT Identity,Emp_name Varchar(100),Emp_Sal Decimal (10,2)) INSERT INTO tblemployee VALUES ('Anand',15000); INSERT INTO tblemployee VALUES ('Neha',12400); INSERT INTO tblemployee VALUES ('Sohan',11500); INSERT INTO tblemployee VALUES ('Vijay',15500); INSERT INTO tblemployee VALUES ('Sapna',14000); I will be creating an AFTER INSERT TRIGGER which will insert the rows inserted into the table into another log table. The main purpose of this log table is to record the changes in the main table. Now, create the log table as:- CREATE TABLE Employee_Log (Emp_ID int,Emp_name varchar(100),Emp_Sal decimal (10,2),Log_Action varchar(100),log_Timestamp datetime) (a) After Insert Trigger This trigger is fired after an INSERT on the table. Let’s create the trigger as: CREATE TRIGGER trgAfterInsert ON tblemployee After INSERT AS declare @empid int declare @empname varchar(100) declare @empsal decimal(10,2) declare @log_action varchar(100) select @empid=i.Emp_ID, @empname=i.Emp_Name, @empsal=i.Emp_Sal from inserted i; set @log_action='Inserted Record -- After Insert Trigger.'; insert into Employee_log (Emp_ID,Emp_Name,Emp_Sal,Log_Action,Log_Timestamp) values(@empid,@empname,@empsal,@log_action,getdate()); PRINT 'AFTER INSERT trigger fired.' GO The CREATE TRIGGER statement is used to create the trigger. THE ON clause specifies the table name on which the trigger is to be attached. The after INSERT specifies that this is an AFTER INSERT trigger. In the trigger body, table named inserted has been used. This table is a logical table and contains the row that has been inserted. I have selected the fields from the logical inserted table from the row that has been inserted into different variables, and finally inserted those values into the log table. To see the newly created trigger in action, lets insert a row into the main table as: insert into tblemployee values('Ram',10500); Now, a record has been inserted into the tblemployee table. The AFTER INSERT trigger attached tothis table has inserted the record into the Employee_Log as: 6 Ram 10500.00 Inserted Record -- After Insert Trigger. 2016-10-10 08:28:00.500 (b) AFTER UPDATE Trigger This trigger is fired after an update on the table. Let’s create the trigger as: CREATE TRIGGER trgAfterUpdate ON tblemployee After UPDATE AS declare @empid int; declare @empname varchar(100); declare @empsal decimal(10,2); declare @log_action varchar(100); select @empid=i.Emp_ID, select @empname=i.Emp_Name, select @empsal=i.Emp_Sal from inserted i; if update(Emp_Name) set @alog_action='Updated Record -- After Update Trigger.'; if update(Emp_Sal) set @log_action='Updated Record -- After Update Trigger.'; insert into Employee_Log(Emp_ID,Emp_Name,Emp_Sal,Log_Action,Log_Timestamp) values(@empid,@empname,@empsal,@log_action,getdate()); PRINT 'AFTER UPDATE Trigger fired.' GO The AFTER UPDATE Trigger is created in which the updated record is inserted into the log table. There is no logical table updated like the logical table inserted. We can obtain the updated value of a field from theupdate(column_name) function. In our trigger, we have used, if update(Emp_Name) to check if the column Emp_Name has been updated. We have similarly checked the column Emp_Sal for an update. Let’s update a record column and see what happens. update tblemployee set Emp_Sal=15000 where Emp_ID=6 This inserts the row into the audit table as: 6 Ram 15000.00 Updated Record -- After Update Trigger. 2016-10-10 08:28:00.500 (c) AFTER DELETE Trigger This trigger is fired after a delete on the table. Let’s create the trigger as: CREATE TRIGGER trgAfterDelete ON tblemployee AFTER DELETE AS declare @empid int; declare @empname varchar(100); declare @empsal decimal(10,2); declare @log_action varchar(100); select @empid=d.Emp_ID, @empname=d.Emp_Name, select @empsal=d.Emp_Sal from deleted d; set @log_action='Deleted -- After Delete Trigger.'; insert into Employee_log (Emp_ID,Emp_Name,Emp_Sal,Log_Action,Log_Timestamp) values(@empid,@empname,@empsal,@Log_action,getdate()); PRINT 'AFTER DELETE TRIGGER fired.' GO In this trigger, the deleted record’s data is picked from the logical deleted table and inserted into the Log table. Let’s fire a delete on the main table. A record has been inserted into the audit table as: 6 Ram 15000.00 Deleted -- After Delete Trigger. 2016-10-10 08:28:00.500 http://www.libitsolutions.com

What is Autonomous transaction in Oracle
 
05:05
What is Autonomous transaction in Oracle. This is very frequently asking question in Interview. Hello Friend, in this Video You can learn how we can give the answer of Autonomous Transactions. An autonomous transaction is available from Oracle 8i. It is a very cool, useful, unique and powerful feature in oracle. An autonomous transaction is an independent transaction that is initiated by another transaction. It must contain at least one Structured Query Language (SQL) statement. When an autonomous transaction is called, the original transaction (calling transaction) is temporarily suspended. The autonomous transaction must commit or roll back before it returns control to the calling transaction. Once changes have been made by an autonomous transaction, those changes are visible to other transactions in the database. Autonomous transactions can be nested. For use Autonomous Transactions feature in program we have to use PRAGMA AUTONOMOUS_TRANSACTION Key word in Program When to use Autonomous Transactions? • Logging mechanism you need to log an error to your database log table. On the other hand, you need to roll back your core transaction because of the error. And you don't want to roll back over other log entries. • Commits and rollbacks in your database triggers If you define a trigger as an autonomous transaction, then you can commit and/or roll back in that code. • Software usage meter You want to keep track of how often a program is called during an application session. This information is not dependent on, and cannot affect, the transaction being processed in the application. Mutation Error Using autonomous transaction we can avoid mutation error.

DML triggers in sql server   Part 43
 
17:45
In this video we will learn about triggers in sql serevr. There are 3 types of triggers 1. DML triggers 2. DDL triggers 3. Logon trigger DML triggers are fired automatically in response to DML events (INSERT, UPDATE & DELETE). DML triggers can be again classified into 2 types 1. After triggers (Sometimes called as FOR triggers) 2. Instead of triggers. After triggers, fires after the triggering action. The INSERT, UPDATE, and DELETE statements, causes an after trigger to fire after the respective statements complete execution. INSTEAD of triggers, fires instead of the triggering action. The INSERT, UPDATE, and DELETE statements, causes an INSTEAD OF trigger to fire INSTEAD OF the respective statement execution.

DDL Triggers in sql server
 
12:31
ddl trigger example ddl trigger example in sql server ddl triggers can be used to In this video we will discuss DDL Triggers in sql server. In SQL Server there are 4 types of triggers 1. DML Triggers - Data Manipulation Language. Discussed in Parts 43 to 47 of SQL Server Tutorial. 2. DDL Triggers - Data Definition Language 3. CLR triggers - Common Language Runtime 4. Logon triggers What are DDL triggers DDL triggers fire in response to DDL events - CREATE, ALTER, and DROP (Table, Function, Index, Stored Procedure etc...). For the list of all DDL events please visit https://msdn.microsoft.com/en-us/library/bb522542.aspx Certain system stored procedures that perform DDL-like operations can also fire DDL triggers. Example - sp_rename system stored procedure What is the use of DDL triggers If you want to execute some code in response to a specific DDL event To prevent certain changes to your database schema Audit the changes that the users are making to the database structure Syntax for creating DDL trigger CREATE TRIGGER [Trigger_Name] ON [Scope (Server|Database)] FOR [EventType1, EventType2, EventType3, ...], AS BEGIN -- Trigger Body END DDL triggers scope : DDL triggers can be created in a specific database or at the server level. The following trigger will fire in response to CREATE_TABLE DDL event. Use SampleDB Go CREATE TRIGGER trMyFirstTrigger ON Database FOR CREATE_TABLE AS BEGIN Print 'New table created' END To check if the trigger has been created 1. In the Object Explorer window, expand the SampleDB database by clicking on the plus symbol. 2. Expand Programmability folder 3. Expand Database Triggers folder Please note : If you can't find the trigger that you just created, make sure to refresh the Database Triggers folder. When you execute the following code to create the table, the trigger will automatically fire and will print the message - New table created Create Table Test (Id int) The above trigger will be fired only for one DDL event CREATE_TABLE. If you want this trigger to be fired for multiple events, for example when you alter or drop a table, then separate the events using a comma as shown below. ALTER TRIGGER trMyFirstTrigger ON Database FOR CREATE_TABLE, ALTER_TABLE, DROP_TABLE AS BEGIN Print 'A table has just been created, modified or deleted' END Now if you create, alter or drop a table, the trigger will fire automatically and you will get the message - A table has just been created, modified or deleted. The 2 DDL triggers above execute some code in response to DDL events (CREATE_TABLE, ALTER_TABLE, DROP_TABLE). Now let us look at an example of how to prevent users from creating, altering or dropping tables. To do this modify the trigger as shown below. ALTER TRIGGER trMyFirstTrigger ON Database FOR CREATE_TABLE, ALTER_TABLE, DROP_TABLE AS BEGIN Rollback Print 'You cannot create, alter or drop a table' END To be able to create, alter or drop a table, you either have to disable or delete the trigger. To disable trigger 1. Right click on the trigger in object explorer and select "Disable" from the context menu 2. You can also disable the trigger using the following T-SQL command DISABLE TRIGGER trMyFirstTrigger ON DATABASE To enable trigger 1. Right click on the trigger in object explorer and select "Enable" from the context menu 2. You can also enable the trigger using the following T-SQL command ENABLE TRIGGER trMyFirstTrigger ON DATABASE To drop trigger 1. Right click on the trigger in object explorer and select "Delete" from the context menu 2. You can also drop the trigger using the following T-SQL command DROP TRIGGER trMyFirstTrigger ON DATABASE Certain system stored procedures that perform DDL-like operations can also fire DDL triggers. The following trigger will be fired when ever you rename a database object using sp_rename system stored procedure. CREATE TRIGGER trRenameTable ON DATABASE FOR RENAME AS BEGIN Print 'You just renamed something' END The following code changes the name of the TestTable to NewTestTable. When this code is executed, it will fire the trigger trRenameTable sp_rename 'TestTable', 'NewTestTable' The following code changes the name of the Id column in NewTestTable to NewId. When this code is executed, it will fire the trigger trRenameTable sp_rename 'NewTestTable.Id' , 'NewId', 'column' Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/ddl-triggers-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/ddl-triggers-in-sql-server_9.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

sql server trigger execution order
 
06:43
sql server set trigger order sp_settriggerorder in sql server sp_settriggerorder example exec sp_settriggerorder In this video we will discuss how to set the execution order of triggers using sp_settriggerorder stored procedure. Server scoped triggers will always fire before any of the database scoped triggers. This execution order cannot be changed. In the example below, we have a database-scoped and a server-scoped trigger handling the same event (CREATE_TABLE). When you create a table, notice that server-scoped trigger is always fired before the database-scoped trigger. CREATE TRIGGER tr_DatabaseScopeTrigger ON DATABASE FOR CREATE_TABLE AS BEGIN Print 'Database Scope Trigger' END GO CREATE TRIGGER tr_ServerScopeTrigger ON ALL SERVER FOR CREATE_TABLE AS BEGIN Print 'Server Scope Trigger' END GO Using the sp_settriggerorder stored procedure, you can set the execution order of server-scoped or database-scoped triggers. sp_settriggerorder stored procedure has 4 parameters @triggername - Name of the trigger @order - value can be First, Last or None. When set to None, trigger is fired in random order @stmttype - SQL statement that fires the trigger. Can be INSERT, UPDATE, DELETE or any DDL event @namespace - Scope of the trigger. Value can be DATABASE, SERVER, or NULL EXEC sp_settriggerorder @triggername = 'tr_DatabaseScopeTrigger1', @order = 'none', @stmttype = 'CREATE_TABLE', @namespace = 'DATABASE' GO If you have a database-scoped and a server-scoped trigger handling the same event, and if you have set the execution order at both the levels. Here is the execution order of the triggers. 1. The server-scope trigger marked First 2. Other server-scope triggers 3. The server-scope trigger marked Last 4. The database-scope trigger marked First 5. Other database-scope triggers 6. The database-scope trigger marked Last Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/sql-server-trigger-execution-order.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/sql-server-trigger-execution-order_11.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html Full SQL Server Course https://www.youtube.com/playlist?list=PL4cyC4G0M1RQ_Rm52cQ4CcOJ_T_HXeMB4 All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists
