Ich habe die udtType-Funktion in ODP.NET nicht verwendet, daher bin ich mir nicht sicher, wie ich Ihr Ziel damit erreichen soll. Um jedoch ein String-Array zu übergeben, brauchen Sie es nicht.
Wie in der beigefügten Dokumentation müssen Sie ein Paket erstellen, das Ihre gespeicherte Prozedur enthält und ein assoziatives Array (nicht VARRAY) als Eingabeparameter verwendet.
Zum Beispiel:
-- Create the table
CREATE TABLE TBLTEST (testID NUMBER, name VARCHAR2(50));
CREATE SEQUENCE seq_test
MINVALUE 1
START WITH 1
INCREMENT BY 1
NOCACHE;
CREATE OR REPLACE PACKAGE pkgTestArrayBinding
AS
-- Define an local scope associative array type called T_ASSOCIATIVE_ARRAY and make it as the type of input parameter
TYPE T_ASSOCIATIVE_ARRAY IS TABLE OF VARCHAR(50) INDEX BY PLS_INTEGER;
PROCEDURE TestArrayBinding(
Param1 IN T_ASSOCIATIVE_ARRAY,
Param2 IN T_ASSOCIATIVE_ARRAY);
END pkgTestArrayBinding;
/
CREATE OR REPLACE PACKAGE BODY pkgTestArrayBinding
AS
PROCEDURE TestArrayBinding(
Param1 IN T_ASSOCIATIVE_ARRAY,
Param2 IN T_ASSOCIATIVE_ARRAY)
AS
BEGIN
-- for all loop to insert them in a batch
FORALL indx IN 1..Param1.COUNT
INSERT INTO tblTest VALUES(seq_test.nextval, Param1(indx));
FORALL indx IN 1..Param2.COUNT
INSERT INTO tblTest VALUES(seq_test.nextval, Param2(indx));
END TestArrayBinding;
END pkgTestArrayBinding;
/
Führen Sie nun diesen Code aus und geben Sie Ihre eigene Verbindungszeichenfolge ein.
