Re: PL/PGSQL - How to pass in variables?

Hi Scott,

You'll have to execute dynamic SQL (see doc chapter "36.6.5. Executing
Dynamic Commands") for your function to work:

CREATE FUNCTION get_table_count(tablename text) RETURNS integer AS
$$
DECLARE   --tablename ALIAS FOR $1;    rowcount INTEGER; BEGIN
   execute 'SELECT count(*) FROM '||tablename into rowcount;   return rowcount;
 END;
$$ LANGUAGE 'plpgsql';


select get_table_count('bar');
get_table_count
-----------------              3
(1 row)




Cheers,
