Hi,
Thanks for the reply ,
I got it working using another begin and end with in a function.
getting in to detail i have done something like this.
create function functionName() return void as '
declare
:
:
begin
:
:
begin
-- perform some transactions say creation of a sequence or tables or any
thing
end;
:
:
end;
It seems that all the statements between begin and end are treated as one
transaction while execution.
Thanks & Regards,
Sri
