Обсуждение: postgres.stat.result exception

I'm working in 7.4.

But I can do this:

(Using your function definition)

CallableStatement stmt = conn.prepareCall("{?=call Save_Status(?)}");
stmt.registerOutParameter(1, java.sql.Types.INTEGER);
stmt.setString(2,"'asdfadf'");
stmt.executeQuery();
System.out.println(stmt.getInt(1));

which outputs 0.

In your function, you return 0. My guess is that it's being treated as a
result set so that's why executeUpdate will not work.

Cheers,

Kim
