+ "`username` = '"+txt_user_name.getText()+"', "
+ "`password` = '"+txt_user_pass.getText()+"', "
+ "`bagian` = '"+cbo_bagian.getSelectedItem()+"' "
+ "WHERE CONVERT(`admin`.`kode_user` USING utf8) = '"+txt_kode_user.getText()+"' LIMIT 1;");
if (mAffect>0) {
System.out.println("Sukses");
}
st.close();
}
