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

Regards,
Jayadevan
