STP unable to generate procudure call

[mab_arif16]

I am calling a sybase stored procedure from the transform STP stage ,
It has an seq file as input ,and I am using transform STP stage,but the stage is not generating a procedure call using parametrs and column mapping.
like Oracle stored procedure generates BEGIN procname(:1,:2) END
Does some body knows the syntax of procedure call to sybase.
I tried
BEGIN procname(:1,:2) END
BEGIN exec procname @start = ORCHESTRATE.Col1, @end = ORCHESTRATE.Col2 END
BEGIN exec procname @start = DSlink12.Col1, @end = DSlink12.Col2 END
but getting error .
Thanks
Arif

Hi,
From memory you can use call or execute for invoking the SP, I'm not sure you need the BEGIN/END in your sql.

But the above refers to a user defined SQL.

Please post the exact error you get
