Hi,
Can anyone please let me know how to fire trigger when stored procedure is created or modified ?
I want such a trigger that checks whether a stored procedure follows defined rule or not.
Where ddl triggers are stored in database ?
Thanks in Advance.

You can do it with DDL trigger. DDL trigger can be created on server level and on database level, but each level has different events that fire the trigger. For example server level ddl trigger can be fired on new database creation, login modification, granting server level permissions etc'. Database level DDL trigger can be fired for table creation, user modification, when procedure that is altered etc'. In your case you can create a database level trigger for procedure creation and procedure modification:
Create trigger CheckTrigger
On database
For create_procedure, alter_procedure

Here you go mate here is one i created to do exactly what you ask, dont forget to create the log table its in the comments, this SP will log when and a stored proc, tirgger, Index is created, altered or deleted and when a table is altered only. It logs Date, who, etc in the comments there is also a section to deny updates or deletes to the log table :w00t:
Create trigger SCHEMA_AUDIT on database
for CREATE_PROCEDURE, ALTER_PROCEDURE, DROP_PROCEDURE,
CREATE_INDEX , ALTER_INDEX ,DROP_INDEX,
CREATE_TRIGGER, ALTER_TRIGGER, DROP_TRIGGER,
ALTER_TABLE

set nocount on

I Modified the trigger to send a mail once it is done. Sadly, it only runs on one database, I wish I could have this in a cursor, So i can apply it to all DB's on my server(s)
alter trigger SCHEMA_AUDIT on database
for CREATE_PROCEDURE, ALTER_PROCEDURE, DROP_PROCEDURE,
CREATE_INDEX , ALTER_INDEX ,DROP_INDEX,
CREATE_TRIGGER, ALTER_TRIGGER, DROP_TRIGGER,
CREATE_FUNCTION, ALTER_FUNCTION, DROP_FUNCTION,
ALTER_TABLE
