[SQL] Making a prepared statement in a stored procedure

[Nathan Pickett]

Hi,
I am trying to convert the following function below:
---START FUNCTION
create or replace function 
update_tmp_sales_report_from_archive_with_prospects() returns integer as '
declare
   row_data record;
begin
   for row_data in select partner_id, count(*) as prospects from 
prospects_2004_09_01
   group by partner_id loop
       update tmp_sales_report_from_archive set prospects = 
row_data.prospects
       where partner_id = row_data.partner_id;
   end loop;

   return 1;
end;
' language 'plpgsql';
--- END FUNCTION
to be able to pass in the table named prospects_2004_09_01, to be prospects_ 
concatanated with the date, so prospects_2004_08_01, prospects_2004_07_01, 
etc.

I tried the following:
-- START TEST FUCTION
drop function update_tmp_sales_report_from_archive_with_prospects(text);
create or replace function 
update_tmp_sales_report_from_archive_with_prospects(text) returns integer as 
'
declare
   in_t ALIAS FOR $1;
   row_data record;
begin
   for row_data in select partner_id, count(*) as prospects in_t
   group by partner_id loop
       update tmp_sales_report_from_archive set prospects = 
row_data.prospects
       where partner_id = row_data.partner_id;
   end loop;

   return 1;
end;
' language 'plpgsql';
-- END TEST FUNCTION
but go the following errors:
DROP FUNCTION
CREATE FUNCTION
You are now connected as new user bp_sales_match_user.
psql:scratch.postgresql:36: WARNING:  Error occurred while executing 
PL/pgSQL function update_tmp_sales_report_from_archive_with_prospects
psql:scratch.postgresql:36: WARNING:  line 5 at for over select rows
psql:scratch.postgresql:36: ERROR:  parser: parse error at or near "$1" at 
character 44

Any suggestions?  Thanks! -Nate
