パラメーター

名前	型	方向	説明
HandleType	SHORT	in	診断情報を取得するハンドルの種別。SQL_HANDLE_*を指定する。
Handle	void*	inout	診断情報の対象となるハンドル。
RecNumber	SHORT	in	取得する診断レコード番号。1始まりで指定する。
DiagIdentifier	SHORT	in	取得する診断フィールドのID。SQL_DIAG_*定数を指定する。
DiagInfo	void*	outoptional	診断情報を受け取るバッファへのポインタ。
BufferLength	SHORT	in	DiagInfoバッファのバイト長。文字列フィールドで意味を持つ。
StringLength	SHORT*	outoptional	実際に書き込まれたバイト数を受け取るポインタ。NULL可。
