Re: [SQL] Prepare Statement

Tom,

Does java.sql.PreparedStatement do the same thing as SQL command
prepare/execute ??
Which one should be used while I am using jdbc talking to postgresql? If
using both, do them help the performance?

Thanks.

Hi,

I have a question about performance, in SQL commands: there is a
prepare/execute command, document says it will improve the performance
while repeatly execute a statement. In java.sql: there is a
PreparedStatement object, which can store precompiled SQL statement,
document says it can improve the performance also. If I use java jdbc to
connect postgresql database, which one I should use? Can I use both?

Thanks.
