パラメーター

名前	型	方向	説明
sesid	JET_SESID	in	列の取得を行うセッションのJET_SESIDハンドル。
tableid	JET_TABLEID	in	値を取得する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	取得対象の列を識別する列ID。
pvData	void*	outoptional	取得した列データを受け取る出力バッファポインタ。NULLで必要サイズのみ照会可能である。
cbData	DWORD	in	pvDataバッファのサイズをバイト単位で指定する値。
pcbActual	DWORD*	outoptional	列の実データ長を受け取る出力ポインタ。バッファ不足の判定に用いる。NULL可。
grbit	DWORD	in	取得動作を制御するビットフラグ。JET_bitRetrieveCopy等で取得元やオフセットを指定する。
pretinfo	JET_RETINFO*	inoutoptional	多値列のタグ番号やオフセットを指定するJET_RETINFO構造体ポインタ。NULL可。
