fix: Rework view filter query to take default values into account
Browse files Browse the repository at this point in the history 
When gathering rows that are visible in views we need to take rows into
account that have no corresponding entry in the columns_TYPE tables. For
those we can match the filter in PHP and include row ids from a left
join where there is no entry.

Taking an example of a yes/no selection:

If the default value of a column doesn't match we end up using the same
query as before for collecting row ids

...
	`id` IN (SELECT `row_id` FROM `oc_tables_row_cells_selection` WHERE (`column_id` = 7) AND (`value` LIKE '"false"'))
...

If the default value matches, we need to include those that do not have
an entry

...
	`id` IN (SELECT `row_id` FROM `oc_tables_row_cells_selection` WHERE (`column_id` = 7) AND (`value` LIKE '"false"'))
OR
	`id` IN (select sl.id from oc_tables_row_sleeves sl LEFT JOIN oc_tables_row_cells_selection se ON sl.id = se.row_id AND se.column_id = 7 WHERE se.id IS NULL)
...
