Hi,
Thanks very much for all the suggestions. Like Andreas said i have to use EXECUTE to do this. That was my guess too but i was putting the INTO cluase into the string before executing it. This is a step forward. The problem now is getting the into to work with a record. Am using a RECORD variable after declaring it in the INTO clause. pg is complaining
ERROR: record "svc_data_rec" is not assigned yet
DETAIL: The tuple structure of a not-yet-assigned record is indeterminate.
CONTEXT: PL/pgSQL function "foo" line 130 at execute statement
I read in the docs the following, "The INTO clause specifies where the results of a SELECT command should be assigned. If a row or variable list is provided, it must exactly match the structure of the results produced by the SELECT (when a record variable is used, it will configure itself to match the result's structure automatically)." That i take to mean that the above is ok. But it ain't.
Thanks again for your guys help...

You should rewrite your plpgsql-function. You can't handle with
string-vars in this way, you must create a string with your complete sql
and EXECUTE this string.
