I have a plpgsql function that takes a few seconds (less than 5) when executed from psql. The same function, when invoked from java via a prepared statement takes a few minutes. There are a few queries in the function. Out of these, the first query takes input parameters for filtering the data. It is this query which takes a long time when the procedure is invoked from java. To ensure that the query does use actual values (and not bind variables) for optimization, we used
execute ' select x.col_type_desc,x.acc_id,acc_svr from (..... ' using d_from_date,d_to_date
It did not help. Any suggestions? It is from_date and to_date on which data gets filtered. We are using the same values for filtering, when we execute it from java/psql
