SET AUTOMATIC RELATIONS
SET AUTOMATIC RELATIONS
SET AUTOMATIC RELATIONS temporarily changes all the manual relations into automatic relations for the entire database in the current process. The relations stay automatic unless a subsequent call to SET AUTOMATIC RELATIONS is made.
This command changes relations set as manual in the Design environment to automatic, just before executing operations that require them to be automatic (such as relational queries and sorts). After the operation is finished, relations can be changed back to manual by calling SET AUTOMATIC RELATIONS again. Any relations set as automatic in the Design environment are not affected by this command. Note: When you pass True to the SET AUTOMATIC RELATIONS command, the automatic mode is "locked" for all the manual relations during the session. In this case, any calls to the SET FIELD RELATION command during the same session are ignored, regardless of whether they are placed before or after SET AUTOMATIC RELATIONS. To "unlock" the automatic mode and take the calls to SET FIELD RELATION into account, pass False to SET AUTOMATIC RELATIONS. |
