你能帮我把一个值从C#传递给refCursor类型。我试图发送dataTable,如下面链接所示,但它无法正常工作。 Pass datatable to refcursor of Oracle stored procedure

存储过程:

PROCEDURE PROC_INS(  P_USERID IN VARCHAR2,
                     P_ATTACH_LIST IN SYS_REFCURSOR,
                     P_out      OUT NUMBER,
                     P_msg     OUT VARCHAR2) AS

V_BRS_USERID         VARCHAR2(50);
V_ATTACHMENT_TYPE_ID BRS_USER_ATTACHMENT.ATTACHMENT_TYPE_ID%TYPE;
V_FILE_NAME          BRS_USER_ATTACHMENT.FILE_NAME%TYPE;
V_FILE_SIZE          BRS_USER_ATTACHMENT.FILE_SIZE%TYPE;
V_FILE_DESCR         BRS_USER_ATTACHMENT.FILE_DESCR%TYPE; 

BEGIN 
LOOP 
FETCH P_ATTACH_LIST INTO V_BRS_USERID, V_ATTACHMENT_TYPE_ID,V_FILE_NAME, V_FILE_SIZE,   V_FILE_DESCR; 
EXIT WHEN P_ATTACH_LIST%NOTFOUND; 
INSERT INTO USER_ATTACHMENT VALUES
        (SEQ_RER_EMP_REP_ID.NEXTVAL,
          V_BRS_USERID,
          V_ATTACHMENT_TYPE_ID,
          V_FILE_NAME,
          V_FILE_SIZE,
          V_FILE_DESCR,
          NULL,
          NULL,
          0,
          0,
          'A',
          P_USERID,
          SYSDATE,
          NULL,
          NULL
        );

END LOOP; 

CLOSE P_ATTACH_LIST;
EXCEPTION
 WHEN OTHERS THEN
 ROLLBACK; -- Transaction mgmt
 p_out := 2;
 p_msg := sqlerrm;

  END PROC_REG_INS_ATTACH;

这是此用户的重复帖子。见Pass datatable to refcursor of Oracle stored procedure

您无法将DataTable绑定到Ref Cursor。你需要传入另一个引用游标,你只能将它作为存储过程/函数的输出,或者对匿名块中的表进行查询...也许你可以创建一个使用不同的包装器存储过程数据类型,例如关联数组。

使用OracleCommandOracleParameter课程。注意OracleParameter的ParameterDirection属性。

以下是我的代码中的示例,我正在调用web_shop_interface.kreiraj_mp_racun存储过程,并为其设置参数:

var fnRac = new OracleCommand();
fnRac.Connection = conn;
fnRac.CommandText = "web_shop_interface.kreiraj_mp_racun";
fnRac.CommandType = CommandType.StoredProcedure;

var ret = new OracleParameter("ret", OracleDbType.Varchar2);
ret.Direction = ParameterDirection.ReturnValue;
ret.Size = 4096;
fnRac.Parameters.Add(ret);

var p1 = new OracleParameter("did", OracleDbType.Decimal);
p1.Value = 15m;
p1.Direction = ParameterDirection.Input;
fnRac.Parameters.Add(p1);

var p2 = new OracleParameter("prn", OracleDbType.Varchar2);
p2.Value = "Invoice 15";
p2.Direction = ParameterDirection.Input;
fnRac.Parameters.Add(p2);

fnRac.ExecuteNonQuery();
