Buffering Must Be Handled Manually in DBC Rules/Triggers (129642)


The information in this article applies to:

  • Microsoft Visual FoxPro for Windows 3.0
This article was previously published under Q129642

SUMMARY

If you choose to use update, delete, or insert triggers within a Visual FoxPro database container (DBC), buffering will not be enabled automatically. You must use the =CURSORSETPROP() function to manually enable the type of buffering desired.

MORE INFORMATION

This behavior is by design. Because automatic implementation of buffering could cause adverse consequences in some situations, buffering will be set to 1 (no buffering).

Normally, you would choose to implement row buffering on the parent table, and table buffering on the child table involved in the relationship.
