If a conflict handler returns this value no special action is taken. The change that caused the conflict is not applied. The session module continues to the next change in the changeset.

SQLITE_CHANGESET_REPLACE

This value may only be returned if the second argument to the conflict handler was SQLITE_CHANGESET_DATA or SQLITE_CHANGESET_CONFLICT. If this is not the case, any changes applied so far are rolled back and the call to sqlite3changeset_apply() returns SQLITE_MISUSE.

If CHANGESET_REPLACE is returned by an SQLITE_CHANGESET_DATA conflict handler, then the conflicting row is either updated or deleted, depending on the type of change.

If CHANGESET_REPLACE is returned by an SQLITE_CHANGESET_CONFLICT conflict handler, then the conflicting row is removed from the database and a second attempt to apply the change is made. If this second attempt fails, the original row is restored to the database before continuing.

SQLITE_CHANGESET_ABORT

If this value is returned, any changes applied so far are rolled back and the call to sqlite3changeset_apply() returns SQLITE_ABORT.
