Oracle関数からretrun値を抽出する必要があります。
これは関数です:
FUNCTION set_idoc
(Pidoctyp in varchar2, -- tip idoc-a
Pdirect in varchar2, -- smjer idoc-a
Psgln01 in varchar2, -- identifikator pošiljatelja
Prgln01 in varchar2, -- identifikator primatelja
Pdtdc01 in varchar2, -- datum i vrijeme kreiranja poruke
Pbodi01 in varchar2) -- identifikator
return number is
Lidoc_num NUMBER;
Lind_obr AGR3PL_IDOC.ind_obr%TYPE;
BEGIN
SELECT SEQ_IDOC.nextval, DECODE(Pdirect, '1', 'U', 'P')
INTO Lidoc_num, Lind_obr
FROM DUAL;
INSERT INTO AGR3PL_IDOC (idoc_num, direct, idoctyp, sgln01, rgln01, dtdc01, bodi01, ind_obr)
VALUES (Lidoc_num, Pdirect, Pidoctyp, Psgln01, Prgln01, Pdtdc01, Pbodi01, Lind_obr);
return Lidoc_num;
EXCEPTION
when others then raise;
END;
したがって、Lidoc_num値を抽出する必要があります
私はこのように試しました:
System.Data.OracleClient.OracleParameter Lidoc_num = new System.Data.OracleClient.OracleParameter();
Lidoc_num.Direction = ParameterDirection.ReturnValue;
Lidoc_num.Size = 16;
com1.Parameters.Add(Lidoc_num);
//Predaj parametre funkciji i vrati broj dokumneta iz baze
com1.CommandText = "TRB01.set_idoc('DOC','1','"
+ sender + "','"
+ reciver + "','"
+ cre_date + "','"
+ bod_ID + "')";
com1.ExecuteNonQuery();
Lidoc_num = com1.Parameters[0].Value;
しかし、何もないので、どうすればこれを行うことができますか
よろしくお願いします!!
