Something like this would work with the postgres-7.4

postgres-8.1 jdbc3.jar driver.
Running with a non-prepared statement works
with 8.1.
I'm running 8.1 server on linux, jdk1.5.
Not sure if this is a bug, or intentional.

s_query = "UPDATE cue.proc SET dt_started = now() - INTERVAL ? WHERE pk=5";
x_stmt = x_conn.prepareStatement ( s_query );
x_stmt.setString ( 1, "0 seconds" );



This is a known limitation of server side prepared statements (which were 
added in the 8.0 JDBC driver).  You may not use the syntax "INTERVAL ?", 
but must instead use "CAST(? AS INTERVAL)" or "?::interval".

Hello!

Something like this would work with the postgres-7.4
jdbc3.jar driver, but fails with the shown error with
postgres-8.1 jdbc3.jar driver.
Running with a non-prepared statement works
with 8.1.
I'm running 8.1 server on linux, jdk1.5.
Not sure if this is a bug, or intentional.

Thanks for the great work!
