Question

I am trying to update a field in my table using Netbeans and I have two conditions. The update statement is as follows:

String sql1 = "update tbl_log set Logout_Time =? where Firstname = ? and Check = ?";
        try{
            pst = conn.prepareStatement(sql1);
            pst.setString(1, time);
            pst.setString(2, username);
            pst.setString(3, "IN");
            pst.execute();
        }catch(Exception e){
            JOptionPane.showMessageDialog(null, e);
        }

but I am getting the following error:

com.mysql.jdbc.exceptions.jdbc4.MySQL SyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘Check = ‘IN’ at line 1

How can I solve it?

Answer 1

“Check” is a reserved word, so you need to put it in backticks

Change it to:

String sql1 = "update tbl_log set Logout_Time =? where Firstname = ? and `Check` = ?";

For a list of reserved words, see here: http://dev.mysql.com/doc/refman/5.5/en/reserved-words.html
