Page “Modes of linking and unlinking” of link creating wizard for indirect link

Purpose

The page allows indicating which operations should be performed with the record of the cross table, when the link between EDB table or query and map feature is being set or broken.

Panes

Linking

Add record into cross table – if the box is checked, before setting a link between the feature and record ObjectLand adds the record into cross table and sets values of all fields of indirect link equal to the values of matched fields in the record of EDB table or query being linked. The rest record fields of the cross table remain empty.

Look for record in cross table – if this box is checked, search of the record in cross table is performed by values of fields of indirect link in the record of EDB table/query being linked. If the record with specified values of fields is found in the cross table, the feature linked with the found record is considered to be linked with the record of EDB table/query as well. Otherwise, ObjectLand informs the user about impossibility to set a link.

If both boxes are checked, search of record in the cross table is performed in the first place and if the record is not found, a new record is added into the cross table.

At least one of the two boxes should be checked. By default both boxes are checked.

Unlinking

Remove record from cross table – when breaking the link between the present record of EDB table/query and the feature, apart from breaking of the link with the cross table, removal of this record is performed.

By default the record in the cross table is not removed.
