I have an output2 pattern and I want to list only records of the chosen value in field 'saison_id'. I searched the net to look for the right SQL solution but I failed. Can you say why my SQL code works with a 'hard' code (2018/2019) and not with the one (training_plan_kopf.saison_id) you see below?

Best regards,

Juergen

$table_id = 'training_plan_anwesenheit'; // table name
$report = 'training_plan_anwesenheit.gesamt.list.report.inc'; // file identifying report structure

// customise the SQL SELECT statement
$sql_select = "tplan_anwesenheit_kontakt_name, tplan_anwesenheit_kontakt_vorname, tplan_anwesenheit_status_grund, tplan_anwesenheit_saison_id, " .
"orga_vereine.vereine_name, orga_vereine.vereine_logo, orga_mannschaften_eigene.mannschaften_desc, " .

Your query is basically
SELECT ... FROM training_plan_anwesenheit LEFT JOIN training_plan_kopf ... 
WHERE training_plan_anwesenheit.tplan_anwesenheit_saison_id = 2018/2019'
If you replace the literal '2018/2019' with the column name training_plan_kopf.saison_id you are basically saying "use whatever value you find in column training_plan_kopf.saison_id", and as there is nothing in that query that limits that value to '2018/2019' it will use whatever values it finds.

But I generate the report from a list2 pattern. That's why I thought that the value 2018/2019 will be taken from the parent record where the value in this case is 2018/2019. Or do I have to consider something else?

What value from the LIST2 screen is being passed to the OUTPUT2 task? Unless you are passing the string
tplan_anwesenheit_saison_id = '2018/2019'
then the query will not limit itself to that selection.

Where can I see this best which value is being passed?

Your OUTPUT2 task is pointed to the training_plan_anwesenheit table, so I suggest you use your debugger and, when inside the _cm_initialise() method of that table's class, examine the contents of the $where and $selection variables.

If I set $sql_where = null; in the controller script, the content of $where in the _cm_initialise() method is exactly what I want, tplan_anwesenheit_saison_id has the value '2018/2019'. The value of $selection is ''.
But in the report are shown the records of '2018/2019' and of '2019/2020' .....

In that case you need to examine the contents of the $where variable in the _cm_pre_getData() method in case it has been changed. This is the method where the various parts of the sql query are defined.

In the _cm_pre_getData() method the $where is '', the $where_array is null and the $parent_data is false.

You will need to step through with your debugger to see what is happening between the call to _cm_initialise() and _cm_pre_getData().

As far as I see is the $where set to '' in include.library.inc in method filterwhere(). The array3 contains the correct values but the array4 is null.

You need to investigate why the filterWhere() function is clearing out that data. It was designed to remove references to fields which do not exist in the structure of the current table.

If I understand you right, the clearing out happens because the fields in the $where string are different to those in the fieldlist. In the fieldlist are the fields of the $tablename table. In the $where string are the fields (with the right values) of the table from which the pattern is called. I hope I did understand you right. As you adviced in one of your articles I try to give unique field names in each table.
Do I have a wrong table name in one of my controller scripts?

When you have the OUTPUT2 (child) task as a navigation button on another (parent) task and you press that navigation button there are two values which are passed to the child task - the original WHERE string of the parent, and a SELECTION string which identifies any rows which you checked using the select box on the parent's screen. The field names used in both strings are the names as known to the parent. If the corresponding names in the child task are different then you have to adjust them manually as described in http://www.tonymarston.net/php-mysql/menuguide/appendixi.htm l

Exactly what I was looking for. Thank you very much. Replacing the $where string with the right primary key fields led to the right solution. Everything seems to work fine now.

Two more questions:
1. As you can see I want to generate a report with a 'Cross' or 'Pivot' table. Do you have an example where you did deal with this? I have now hard coded the columns but each time I insert a new column I have to change my code.

2. Is there a possibility to output the 1 in a boolean field as a check mark?

If by a 'Cross' or 'Pivot' table you mean an intersection table which handles a Many-to-Many relationship, then take a look at https://www.tonymarston.net/php-mysql/dialog-types.html#link 1. There are several examples of this pattern in the MENU subsystem.

No, that's not what I am looking for. I want to sum how many times a person was out (wasn't available), grouped by the reason. But the reasons are listed in a different table and the number can change. For your understanding what I mean:

Person - reason 1 - reason 2 - reason 3 - ....
1 - 3 - 0 - 2 - ....
2 - 1 - 2 - 0 - ....
3 - 5 - 3 - 1 - ....

I hope I could explain what I mean.

I do not have a particular pattern for that. You need to identify the particular SQL query which does that, then modify one of your classes to issue that query.
