Question

我创建了一个包：

create or replace PACKAGE merc
AS 
 TYPE resultcurtyp is REF CURSOR;
END merc;

然后是存储过程：

create or replace PROCEDURE merc_results
(
 testP IN VARCHAR2 DEFAULT NULL,
 CURSOR_ IN OUT merc.resultcurtyp

) AS 
BEGIN
    OPEN CURSOR_ FOR
    SELECT /*csv*/
    FR.*
    FROM DS.table1 FR 
    INNER JOIN DS.price PN ON PN.OBJECTID = FR.SOURCEID 
    WHERE FR.NAME = testP   
END merc_results;

调用Stored proc表单.Net代码给我：

ORA-06550: line 1, column 15:
PLS-00222: no function with name 'merc' exists in this scope
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

我是否需要创建包，从中调用存储，然后从.Net调用包？我现在直接从代码调用存储过程。我之前没有使用过oracle db。

在c＃中：

OracleCommand cmd = new OracleCommand("yourshema.merc.merc_results", Connection);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("testP", testP);
cmd.Parameters.Add("CURSOR_", OracleDbType.RefCursor).Direction = ParameterDirection.Output;
OracleDataAdapter da = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
return ds;

Oracle Package：

CREATE OR REPLACE PACKAGE merc
IS
    TYPE resultcurtyp IS REF CURSOR;
    PROCEDURE merc_results(
        testP IN VARCHAR2 DEFAULT NULL,
        CURSOR_ OUT resultcurtyp );
END;
/

CREATE OR REPLACE PACKAGE BODY merc
IS
  PROCEDURE merc_results(
    testP IN VARCHAR2 DEFAULT NULL,
    CURSOR_ OUT resultcurtyp )
  AS
  BEGIN
   OPEN CURSOR_ FOR SELECT
    FR.* FROM DS.table1 FR INNER JOIN DS.price PN ON PN.OBJECTID = FR.SOURCEID WHERE FR.NAME = testP;
  END merc_results;
END merc;
/

使用.Net执行Oracle Stored Proc
