message from server: Not unique table/alias: 'USER_ROLE' ?
What does the error mean ? - message from server: Not unique table/alias: 'USER_ROLE' This happens when I try to use the java code: PreparedStatement pstmt = con.prepareStatement(Select * From USER_ROLE, ROLE + WHERE USER_ROLE.USERID = ? And USER_ROLE.ROLEID = ROLE.ID); pstmt.setInt(1, id); ResultSet rs = pstmt.executeQuery(); If i execute the same query at mysql prompt, it works perfectly fine as is. Is their a problem with the JDBC driver ? Thanks.

Re: Not unique table/alias
Hi, I think that when you use a table for one operation pe select or insert, the table is locked and you cannot execute another operation. In your statement if you use different tables for the two operations, I don't think you'll have a problem... Ciprian I.

Not unique table/alias
What does this mean? It is referring to the following SQL statement: INSERT INTO MaterialSubwall SELECT subwallClassId, mirrorEW, rotation + 180, sizeX, sizeY, offsetS, offsetW, offsetN, offsetE FROMMaterialSubwall; AFAIK, this is perfectly valid SQL syntax.

Re: Not unique table/alias
Check out the 2nd bullet under 7.21.1 of the manual: http://www.mysql.com/documentation/mysql/bychapter/manual_Reference.html#INSERT_SELECT You could do this by creating a temporary table out of MaterialSubwall and using that to select rows for the insert. - TIM What does this mean?
