Hi Hauser,

I have an sql script file which recreates 10 procedures and whenever I make
changes in any of the procedure, I just run that file, and if the procedure
does not exist and I use drop procedure, then the script stops and system
raises error that procedure cannot be drop because it does not exist.

Thats why I want to drop the procedure if it exists,before creating it 
again.

In oracle, create or replace procedure is very handy, while in sql server, 
IF EXISTS can be used to check
for procedure existance.


Best Regards,

Luqman

Hi Larry and Luqman,

there is no UPDATE PROCEDURE or CHANGE PROCEDURE in SQL.
You have to drop the procedure before it can be recreated.
And because of the ability of overloading procedures, it is possible to have
a procedure with the same nambe but different number of parameters in the
same schema (or library).

If a procedure is overloaded, you must either specify the parameter
definitions or the specific name when dropping the procedure.

An IF-Statement can only be used in Triggers, Stored Procedures or User
Defined Functions.

But why no simply typing the drop statement and executing it.
If the procedure does not exist, the drop statement will not be successful!

In a Second Statement you can create the function.

Both statements can be seperated by semi colons (;)
and executed one after the other.

Hi Luqman,

<snip>
How can I check using Navigator Run Sql Script, if the procedure already
exists, drop it before recreating it.
</snip>

You should be able to use:

CREATE or UPDATE procedure MYPROCEDURE... ?

Cheers
