Re: Slow statement when using JDBC - Mailing list pgsql-jdbc

Hi Dave,

            Thanks for your reply. I am using postgresql jdbc driver. Here
is my code that executes the query

            *Class.forName("org.postgresql.Driver");
            String pConnectionStr = "jdbc:postgresql://localhost:5432/mydb";
            conn = DriverManager.getConnection(pConnectionStr);
            String sql = "select place_id, (select count(*) from (select
unnest(ARRAY[5098092,10799979,7470935,10799979,5957205,23663129]) INTERSECT
select unnest(nameaddress_vector))s) as exactmatch from search_name where
name_vector @> ARRAY[4784827] and nameaddress_vector @>
ARRAY[17247,202321,10250,7791183,1099136,63895,202321,46909,23663130] order
by (case when importance = 0 OR importance IS NULL then
0.75-(search_rank::float/40) else importance end) DESC, exactmatch DESC
limit 2";
            stmt = conn.createStatement();
            stmt.executeQuery(sql)*;

            The above query takes 440ms in jdbc connection. But when i
execute the same query in psql client,it takes only 210ms.

Regards,
Vijay K
