残念ながら、OracleJDBCドライバはPL/ SQL RECORD
へのアクセスを提供しません。 タイプ、IN
のどちらでもない OUT
も パラメータ。
単一のプロシージャ呼び出しの回避策:
ただし、JDBC(またはSpring JDBC)で匿名のPL / SQLブロックを直接使用することで、この制限を回避できます。
DECLARE
rec MY_PACKAGE.MY_RECORD;
BEGIN
-- Replace these by your actual record attributes:
rec.first_name := ?;
rec.last_name := ?;
...
p_insertclient(rec);
END;
これは、1回のプロシージャ呼び出しで完全に機能します。
これらの呼び出しの多くに対する固溶体:
上記を頻繁に行う場合は、匿名のPL / SQL文字列を常に手動で書き込むのではなく、自動的に生成するスタブを生成する価値があります。すべてのPL/SQL RECORD
を自動的に検出できます 次のクエリでスキーマを入力します:
