Can we call a Trigger in store procedure? [Resolved]

A trigger is a pl/sql block structure which is fired when a DML statements like Insert, Delete, Update is executed on a database table. A trigger is triggered automatically when an associated DML statement is executed.

Syntax of Triggers

The Syntax for creating a trigger is:

CREATE [OR REPLACE ] TRIGGER trigger_name

{BEFORE | AFTER | INSTEAD OF }

{INSERT [OR] | UPDATE [OR] | DELETE}

[OF col_name]

ON table_name

[REFERENCING OLD AS o NEW AS n]

[FOR EACH ROW]

WHEN (condition)

BEGIN

--- sql statements

END;

SQL Server 2000 has many types of triggers:

1. After Trigger
2. Multiple After Triggers
3.Instead Of Triggers
4. Mixing Triggers Type

Trigger can't be called , it is automatically executed when we insert,update or delete a table row

Triggers are event based statements so they cannot be called explicitly by user in any means.

Differences between storedprocedures and triggers
1. When you create a trigger you have to identify event and action of your trigger but when you create s.p you don't identify event and action

2.Trigger is run automatically if the event is occured but s.p don't run automatically but you have to run it manually

3. Within a trigger you can call specific s.p but within a sp you cannot call atrigger

4.Trigger execute implicitly whereas store procedure execute via procedure call from another block.

5.We can call a stored procedure from front end (.asp files, .aspx files, .ascx files etc.) but we can't call a trigger from these files.

6. Stored procedure can take the input parameters, but we can't pass the parameters as an input to a trigger.

Triggers are event based. It is getting called when insertion, deletion or update happen to the table. Trigger cannot be called from store proc.
