SQL: Delete Vs Truncate Vs Drop
 
08:27
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.

PL/SQL tutorial : Trigger in Oracle Database 11g Complete guide

Learn in depth about trigger in oracle database 11g, and usage of trigger in Database, different types of trigger with syntax for various events along with writing advance trigger and capturing all details regarding authentication. Explained Instead of trigger. Trigger in Oracle, Trigger in PL/SQL, Oracle Trigger, PL/SQL Trigger, What is Trigger in pl/sql, How to use Trigger in pl/sql, How to write a Trigger in oracle, How to design Trigger in pl/sql, DDL trigger, DML trigger, Instead of trigger, Compound trigger, Logon trigger, Introduction to Triggers You can write triggers that fire whenever one of the following operations occurs: DML statements (INSERT, UPDATE, DELETE) on a particular table or view, issued by any user DDL statements (CREATE or ALTER primarily) issued either by a particular schema/user or by any schema/user in the database Database events, such as logon/logoff, errors, or startup/shutdown, also issued either by a particular schema/user or by any schema/user in the database Triggers are similar to stored procedures. 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/

Sql triggers tutorial in hindi
 
08:51
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

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

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.

Difference Between Delete and Truncate
 
03:41
Below is link for Useful Pl/SQL Books http://goo.gl/XMy0tt ---------------------------------------------------------- Difference Between Delete and Truncate in Detail On bigger picture they serve the same purpose but there are many Differences listed with examples Point Delete Truncate 1. Data Recovery Delete: Come under the DML Category, we need to commit or Rollback explicitly to make the changes permanent, so we can recover the data by Rollback command fully with in a session or up to a point if Save Points are used Fall In DDL Category (DDL Command issue the Auto commit implicitly) so no chances of Recovery even not using the Flashback table method. But Truncate operations are also logged , they didn’t generate redo SQL but they are logged , view for truncated data info V$LOGMNR_CONTENTS 2. Data Removal Delete Can remove all or selected data using the Where Clause predicates. Or we can say delete any subset of rows We can Truncate complete table or a partition or sub partition of a table. 3. Speed Delete is Slower because oracle maintain the redo logs for Read Consistency (so that every session connected can see a consistent data at a given point of time ) Delete is very time consuming activity especially when table have numerous indexes and Triggers associated with table Faster as no data logs are maintained no associated trigger firing. 4. DML Triggers Firing DML (Delete) triggers associated with table will fire. DML Trigger will not fire in case of truncate method. 5. Flashback Technology Data can be recovered even after commit operation using Flashback Table options Flashback_transaction_query table will give what to recover and up to which point. Data cannot be recovered in truncate method by Flashback table option. 6. Referential Integrity Constraint Behavior if we don’t have related data in child table then we can delete the data from the parent table or we have variants like On Delete Cascade & on Delete set Null. We can’t truncate a table with enable Referential Integrity Constraint, even there is no data in the child table, we have to disable or drop the constraint if we want to truncate the table. Exception: Truncate is possible if the FK is self-referential means primary key and foreign key are on the same table. 7. Space De allocation or Space Utilization No extent reset with delete when deleting rows from a table, extents are not de allocated, So if there were 50 extents in the table before the deletion, there will still be 50 after the deletion. Truncate: When a table is truncated it will free the space allocated except in case of reuse storage clause. This space can subsequently be used only by new data in the table or cluster resulting from insert or update operations .All extents are de allocated leaving only the extents specified when the table was originally created .Example So if the table was originally created with min extents 3, there will be 3 extents remaining when the tables is truncated. When you truncate a table, NEXT is automatically reset to the last extent deleted. 8. High Water Mark Delete will not reset the high water mark Truncate will reset the High Water mark which is very important for performance point of view as in case of full table scan and full index scan oracle will read all the block under high water mark this makes a lot of difference in terms of performance. 9. Cluster No as such restriction with delete. You cannot individually truncate a table that is part of a cluster. You must truncate the cluster, Delete all rows from the table, or drop and re-create the table. 10. Information Capturing Delete : we can capture the row information what we have deleted using Delete Method, f you are deleting multiple records then use composite data types (collections & records) Truncate Don’t have this feature of capturing the deleted records. 11. Function Based Index Impact DELETE You cannot delete rows from a table if a function-based index on the table has become invalid. You must first validate the function-based index. Truncate: No as such restriction 12. UNUSABLE Indexes Delete no as such feature. Truncate if table is not empty then truncate make all unusable indexes to useable. 13. Complex views You cannot delete data from a Complex view except through INSTEAD OF triggers. But we can delete data from simple Views and MV. We cannot truncate a view simple or complex but you can truncate MV with special Features like Preserve MV Logs and Purge MV Logs. 14. Privileges Delete You need to provide delete table privilege on object. Truncate you must have drop table privilege there is no truncate table privilege exists. 15. Domain Index No as such restriction You cannot truncate the object having domain index in invalid or In progress state
