AUTOMATIC RELATIONS

version 3

AUTOMATIC RELATIONS (one{; many})

Parameter	Type		Description
one	Boolean		Many-to-one relations
many	Boolean		One-to-many relations

AUTOMATIC RELATIONS temporarily changes all manual relations into automatic relations for the entire database. The relations stay automatic unless a subsequent call to AUTOMATIC RELATIONS is made.

If one is true, then all manual Many-to-One relations will become automatic. If one is false, all previously changed Many-to-One relations will revert to manual relations.

The same is true for the many parameter, except that manual One-to-Many relations are affected.

Relations that are set as automatic in the Design environment are not affected by this command.

If all relations have been set as manual in the Design environment, this command makes it possible to change them to be automatic, just before executing operations that need the relation to be automatic (such as relational searches and sorts). After the operation is finished, the relation can be changed back to manual.

The following example makes all manual Many-to-One relations automatic and reverts any previously changed One-to-Many relations:

   AUTOMATIC RELATIONS (True; False)
