Description

This function returns the number of row changes caused by INSERT, UPDATE or DELETE statements since the database connection was opened. The count includes all changes from all trigger contexts. However, the count does not include changes used to implement REPLACE constraints, do rollbacks or ABORT processing, or DROP table processing. The changes are counted as soon as the statement that makes them is completed (when the statement handle is passed to DatabaseReset or DatabaseFinalize).


Available in MUSHclient version 4.40 onwards.



Lua example

changes = DatabaseTotalChanges ("db")


Return value

A positive integer, or zero, indicating the count of changes.

Otherwise:

-1 : Database id not found
-2 : Database not open
