Question

So i have this code which should supply me with the id of a row.

public int getIdSala(Connection conn, String t) {
    try {
        String query = "Select id_sala from sala where nume = ?";

        PreparedStatement st = conn.prepareStatement(query);
        st.setString(1, t);
        ResultSet rs = st.executeQuery(query);

        id = rs.getInt("Id_sala");

    } catch (Exception e) {
        System.err.println("Got an exception!");
        System.err.println(e.getMessage());
    }
    return id;
}

And I get the following error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQLserver version for the right syntax to use near '?' at line 1

What could be the problem?

Answer 1

Don’t do st.executeQuery(query) but just st.executeQuery()
