NAME
sqlite3session_isempty —
Test if a
changeset has recorded any changes.
SYNOPSIS
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.
