SQLITE3SESSION_ISEMPTY(3)

NAME
sqlite3session_isempty - test if a changeset has recorded any changes

SYNOPSIS
#include <sqlite3.h>
int
sqlite3session_isempty(sqlite3_session *pSession);

DESCRIPTION
Return non-zero if no changes to attached tables have been recorded by the session object passed as the first argument. Otherwise, if one or more changes have been recorded, return zero.

Even if this function returns zero, it is possible that calling sqlite3session_changeset() on the session handle may still return a changeset that contains no changes. This can happen when a row in an attached table is modified and then later on the original values are restored. However, if this function returns non-zero, then it is guaranteed that a call to sqlite3session_changeset() will return a changeset containing zero changes.

IMPLEMENTATION NOTES
These declarations were extracted from the interface documentation at line 11410.
