A trigger stored in the database can include SQL and PL/SQL or Java statements to run as a unit and can invoke stored procedures. However, procedures and triggers differ in the way that they are invoked. A procedure is explicitly run by a user, application, or trigger. Triggers are implicitly fired by Oracle when a triggering event occurs, no matter which user is connected or which application is being used. How Triggers Are Used Triggers supplement the standard capabilities of Oracle to provide a highly customized database management system. For example, a trigger can restrict DML operations against a table to those issued during regular business hours. You can also use triggers to: Automatically generate derived column values Prevent invalid transactions Enforce complex security authorizations Enforce referential integrity across nodes in a distributed database Enforce complex business rules Provide transparent event logging Provide auditing Maintain synchronous table replicates Gather statistics on table access Modify table data when DML statements are issued against views Publish information about database events, user events, and SQL statements to subscribing applications Linkedin: https://www.linkedin.com/in/aditya-kumar-roy-b3673368/ Facebook: https://www.facebook.com/SpecializeAutomation/

Mutating Trigger in Oracle - Mutating Table in Oracle - Mutating Table Error in Oracle Trigger
 
25:41
Mutating table error in oracle database comes only in Row Level trigger. Mutating trigger error in Oracle is not thrown by the Statement Level triggers. Mutating table error in oracle trigger is common when row level trigger contains an SQL statement targeted at the same table on which the trigger has been written.

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.

Sql triggers tutorial in hindi

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

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.

The table data will not be affected, in other words if you want to insert or update the data of the table then you need to write it in the trigger using "inserted" or "deleted" virtual tables

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.

Check Last Modified DateTime for An Object (Table,Stored Procedure,Trigger etc.) in SQL Server
 
04:23
We as SQL Server developers send our DDL Scripts ( Add New Column, Drop some column from table, or Alter Stored Procedure) to DBA. After deployment we verify those changes and sometime it happens that the changes are not done. Maybe DBA has missed one of the script to run. If we can get the last modified date for object ( Table,Stored Procedure, View etc) that can confirm the changes are done on given date. blog post link for scripts used in this video http://sqlage.blogspot.com/2014/01/tsql-how-to-check-when-object-table.html

Oracle SQL Tutorial 13 - How to Add Column Constraints (Attributes)
 
05:55
So far, we have this table declaration: CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR) first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) We can run this command see that it works. As we are learning though, we are going to want to be able to recreate our table with different settings and such, but if you try to run this command, it will complain that the table already exists. So we first need to delete this table before we start editing settings. When we get more experienced, we will learn about ways to edit the structure of a table that already exists. To fix this, we can get rid of the table using the DROP TABLE command: DROP TABLE users You can run this every time if you need to practice by adding a semicolon after it. This is how you can tell Oracle that you are putting in another command after it. This is known as a delimiter. When you run the script, it is going to run both commands. Now we can go through and reconsider our table structure. This is fine for starting out because we don't have any important data in our database, but once your database is in production you are not going to want to just drop tables. In the last video we discussed different constraints that you can apply to columns in a database table, but how do you actually apply these when you are creating a table? The first way you define constraints is to put them right after the column in your CREATE TABLE statement. CREATE TABLE users( username VARCHAR2(50 CHAR) NOT NULL ) When we define constraints this way, we usually say we are adding column attributes. If you have two constraints you want to add, you just put one after the other with spaces in between. There is no particular order that is required. CREATE TABLE users( username VARCHAR2(50 CHAR) NOT NULL UNIQUE ) In this situation we have already given the column the NOT NULL and UNIQUE attributes, so we should consider making this a primary key: CREATE TABLE users( username VARCHAR2(50 CHAR) PRIMARY KEY ) As you can see, adding column attributes is super easy. We can add a default like this: CREATE TABLE users( username VARCHAR2(50 CHAR) PRIMARY KEY, account_balance NUMBER DEFAULT 0 ) Note that now we need the comma after the first row. There are a few constraints we did not talk go through an example, specifically foreign keys and check constraints. We will be adding these constraints to our database in future videos. In the mean time, I have a thought for you… Many people prefer to name their column constraints. That way, we can refer to certain constraints by name. For example, we might have a primary key constraint that could be named users_pk. The way we are creating these constraints does not allow for this feature, so in the next video we are going to be discussing different ways to create constraints. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me on Patreon! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

How to Create & Drop Trigger in MySQL
 
08:47
This MySQL Trigger video tutorial shows the simple steps to create trigger, drop trigger, and show triggers in MySQL at phpMyAdmin. For your better understand we'll demonstrate MySQL trigger example with a sample table called "users". This "users" table has "id", "first_name", "last_name", and "full_name" columns. At first we'll create a BEFORE INSERT TRIGGER for inserting "full_name" column value when a row is inserted in "users" table. "full_name" value would be the combination of "first_name" and "last_name" value. After that, we'll update the "full_name" column value as per the "first_name" and "last_name" value when a row is updated using BEFORE UPDATE TRIGGER. You can show all the triggers in the database using SHOW TRIGGERS statement. Use DROP TRIGGER statement to drops a trigger.
