I read FAQ08 and FAQ84 but I struggle all day long with the SQL syntax and I don't know what I am doing wrong. I try to improve my SQL skills (as you suggested) but this is at the moment obiously too much for me.

This component script of the popup2 will show no entries.

$outer_table = 'training_plan_uebungskategorie'; // name of outer (parent) table
$inner_table = 'training_plan_uebungen_kategorie'; // name of inner (child) table
$screen = 'training_plan_uebungen_kategorie.popup2.screen.inc'; // file identifying screen structure

// customise the SQL SELECT statement
$outer_sql_select = null;

$inner_sql_select = null;
$inner_sql_from = 'training_plan_uebungen_kategorie '
. 'LEFT JOIN training_plan_uebungen ON ('
. 'training_plan_uebungen.training_plan_uebung_no = training_plan_uebungen_kategorie.u_training_plan_uebung_no AND '
. 'training_plan_uebungen.rdcaccount_id = training_plan_uebungen_kategorie.u_rdcaccount_id) ';
$inner_sql_where = null;

require 'std.list2.popup.inc'; // activate page controller

The following error message and the SQL statement will be shown if the default sort order of the link table is a field value of one of the parent tables (linked with a relationship).

Fatal Error: MySQL: Unknown column 'training_plan_kategorie_desc' in 'order clause' (# 1054)

SQL query: SELECT SQL_CALC_FOUND_ROWS * FROM training_plan_uebungen_kategorie LEFT JOIN training_plan_uebungen ON (training_plan_uebungen.training_plan_uebung_no = training_plan_uebungen_kategorie.u_training_plan_uebung_no AND training_plan_uebungen.rdcaccount_id = training_plan_uebungen_kategorie.u_rdcaccount_id) WHERE

training_plan_uebungen.rdcaccount_id='1'

AND training_plan_uebungen_kategorie.k_training_plan_kategorie_i d='ABW-GRDU' AND training_plan_uebungen_kategorie.k_rdcaccount_id='1' ORDER BY training_plan_kategorie_desc asc LIMIT 10 OFFSET 0

The expression "training_plan_uebungen.rdcaccount_id='1'" is obviously inserted by the framework. If I change the values of rdcaccount_id to 1, the records will not be shown.
Do I have to change the where clause, too?
