Re: query not working with JDBC driver

Hi everyone, I'm stuck on a little problem with what may be the JDBC driver or that I don't fully understand the SQL syntax. I am connecting to the PostGreSQL database with the JDBC Driver for PostGreSQL. When I run the following command, I get this: (java code) : String query = "SELECT version( )"; ResultSet rs = st.executeQuery(query); (output from standard output) : Column Returned PostgreSQL 8.0.0beta5 on i686-pc-mingw32, compiled by GCC gcc.exe (GCC) 3.3.1 (mingw special 20030804-1) I assume that the output is a good sign...meaning I am connected to the database and can "communicate" with it. Although, when I try to do a simple SQL query on a table, I get an error. The table "cities" does exist, because I can see it when I use pgAdminIII, in addition, when I use pgAdminIII, I am able to click on the SQL query icon(bring up a new window) and perform the simple SQL query from there. (java code): String query = "SELECT * FROM cities"; ResultSet rs = st.executeQuery(query); (output from standard output): Error somewhere in the query: java.sql.SQLException: ERROR: relation "cities" does not exist If anyone could help shed some light on this I would be very thankful. Again, I apologize if this is not the best place to post this question.(I'm not sure what category it best falls under) Thank you all again and kind regards, Jeffrey ---------------------------------------------------------------------------------------- This is a PRIVATE message.
