パラメーター

名前	型	方向	説明
sesid	JET_SESID	in	エスクロー更新を行うセッションのJET_SESIDハンドル。
tableid	JET_TABLEID	in	対象レコードを持つテーブルのカーソルハンドル。
columnid	DWORD	in	エスクロー更新対象の列を識別する列ID。JET_bitColumnEscrowUpdate属性が必要である。
pv	void*	in	現在値に加算する差分値を格納したバッファポインタ。
cbMax	DWORD	in	pvバッファのサイズをバイト単位で指定する値。
pvOld	void*	outoptional	更新前の列値を受け取る出力バッファポインタ。NULL可。
cbOldMax	DWORD	in	pvOldバッファのサイズをバイト単位で指定する値。
pcbOldActual	DWORD*	outoptional	pvOldに書き込まれた実バイト数を受け取る出力ポインタ。NULL可。
grbit	DWORD	in	エスクロー更新動作を制御するビットフラグ。通常は0を指定する。
