Looked at the MySQL Documentation for Create Procedure and did this as the "root" user...
It does work but it looks like the output is supposed to be put into a table. In this case a temp table. You'll have to fetch the row from the temp table "@a".
Also found that it would only work if I was the "root" user because the normal user didn't seem to have "execute" privilege.
Modify your PERL code to model what's above. Check the procedure it creates via mysql. Login as "root" again and then...
The reason to verify the procedure is because of the delimiter included with the procedure. Did the semicolon get in there or did it cause an error?
After that all works as "root" you can attempt each step as a normal user and see what extra privileges need to be enabled.
Also have a look at CREATE FUNCTION, same doc as link above. The hello_world() function is run from a SELECT so you could probably do something like...
...and then fetch the row.

Hi,
Thanks for the reply,
I am a root user.
I tried for procedure like this:
But still i am unable to execute the procedure from Perl.
I am getting this error:
I am finding an difficulty in calling procedure.
Did a lot of googling and found that many people have this problem. PHP people got rid of it with the PDO interface but I found an example of a simplified answer for PERL.
First, the stored procedure must be simplified.
Second, we call it and fetch the row.
There's no more IN or OUT variables, that PERL can't deal with, and we got rid of the temp table. That was a tough find.
Also found a procedure which works with a parameter.
Don't see any examples of using IN OUT INOUT variables at the link you posted which was what the problem was. Once they are removed any stored procedure can be used with the current version of DBI::\DBD as long as it is reasonably recent.
I have found nothing to suggest that the above variables are supported in the latest version.
