ODP.NET Bagaimana cara melewatkan array string ke prosedur Oracle Stored?

Saya belum pernah menggunakan fitur udtType di ODP.NET, jadi saya tidak yakin bagaimana mencapai tujuan Anda dengan ini. Namun, untuk melewatkan array string, Anda tidak memerlukannya.

Seperti dokumentasi yang Anda lampirkan, Anda perlu membuat paket yang berisi prosedur tersimpan Anda, dan menggunakan array asosiatif (bukan VARRAY) sebagai parameter input.

Misalnya:

-- 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;
/

Sekarang, jalankan kode ini, masukkan string koneksi Anda sendiri.

namespace Con1

    using System;
    using System.Data;

    using Oracle.DataAccess.Client;

        {
            var con = new OracleConnection { ConnectionString = "User Id=usr;Password=pass;Data Source=XE" };

            con.Open();
            Console.WriteLine("Connected to Oracle" + con.ServerVersion);

            // create command to run your package
            var cmd = new OracleCommand("BEGIN pkgTestArrayBinding.TestArrayBinding(:Param1, :Param2); END;", con);

            var param1 = cmd.Parameters.Add("Param1", OracleDbType.Varchar2);
            var param2 = cmd.Parameters.Add("Param2", OracleDbType.Varchar2);

            param1.Direction = ParameterDirection.Input;
            param2.Direction = ParameterDirection.Input;

            // Specify that we are binding PL/SQL Associative Array
            param1.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
            param2.CollectionType = OracleCollectionType.PLSQLAssociativeArray;

            // Setup the values for PL/SQL Associative Array
            param1.Value = new[] { "First Element", "Second Element ", "Third Element_" };
            param2.Value = new[] { "Fourth Element", "Fifth Element ", "Sixth Element " };

            // Specify the maximum number of elements in the PL/SQL Associative Array
            // this should be your array size of your parameter Value.
            param1.Size = 3;
            param2.Size = 3;

            // Setup the ArrayBindSize for each elment in the array, 
            // it should be bigger than the original length of element to avoid truncation
            param1.ArrayBindSize = new[] { 13, 14, 13 };

            // Setup the ArrayBindSize for Param2
            param2.ArrayBindSize = new[] { 20, 20, 20 };

            // execute the cmd
            cmd.ExecuteNonQuery();

            // I am lazy to query the database table here, but you should get you data now.
            // watch what happened to element "Third Element_"

            // Close and Dispose OracleConnection object
            con.Close();
            con.Dispose();
            Console.WriteLine("Disconnected");
        }

        #endregion
    }
