Hello all,
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
It looks highly unlikely that a function execution will take more time through different client interfaces. May be you want to log the function input parameters and see if they are coming different through these interfaces (I think you can use RAISE NOTICE for that). I'm not sure but client side encoding might also cause changes in the real values of the date parameters you are passing (e.g mm/dd/yy vs dd/mm/yy). So that will be worth checking as well.
Thanks,
Pavan
