您可以利用多个PreparedStatement获得所需的结果：
// Prepare pre for PreparedStatement #1String varOne = "A";String varTwo = "B";String varThree = "C";String queryOne = "UPDATE blah set x=? y=? z=?"PreparedStatement firstStmt = conn.prepareStatement(queryOne);firstStmt.setString(1, varOne);firstStmt.setString(2, varTwo);firstStmt.setString(3, varThree);firstStmt.executeUpdate();conn.commit();// Prepare pre for PreparedStatement #2String varoneB = "X";String varTwoB = "Y";String varThreeB = "Z";String varFourB = "A";String queryOne = "UPDATE blah set a=? b=? c=? d=?"PreparedStatement secondStmt = conn.prepareStatement(queryTwo);secondStmt.setString(1, varOneB);secondStmt.setString(2, varTwoB);secondStmt.setString(3, varThreeB);secondStmt.executeUpdate();conn.commit();
