【中文标题】调用中的参数数量或类型错误

【英文标题】：wrong number or types of arguments in call

【问题描述】：

我认为输出参数代码有问题。但我不知道如何解决这个问题。谁能告诉我我的代码有什么问题？

错误：

ORA-06550：第 1 行，第 7 列：PLS-00306：调用“SP_WF_GET_REQUESTDETAILS”时参数的数量或类型错误 ORA-06550：第 1 行，第 7 列：PL/SQL：语句被忽略

我的代码

public DataResponse<DataTable> GetRequestCount(string Usercode)

    try
    
        var paramList = new List<OracleParameter>();
        paramList.Add(new OracleParameter("P_IN_KEY", "GET_REQUEST_COUNT"));
        paramList.Add(new OracleParameter("P_USER_CODE", Usercode));
        OracleParameter param = new OracleParameter("P_OUT_OPEN", OracleType.Cursor);
        OracleParameter param1 = new OracleParameter("P_OUT_APPROVED", OracleType.Cursor);
        OracleParameter param2 = new OracleParameter("P_OUT_REJECTED", OracleType.Cursor);
        param.Direction = ParameterDirection.Output;
        param1.Direction = ParameterDirection.Output;
        param2.Direction = ParameterDirection.Output;
        paramList.Add(param);
        paramList.Add(param1);
        paramList.Add(param2);
        var data = SPExcute("SP_WF_GET_REQUESTDETAILS", paramList);
        return data;  
    
    catch (Exception ex)
    
        ex.LogInfo();
        return new DataResponse<DataTable>(DataResponseCode.InvaildInputs);
    

我的存储过程

    END IF;
END SP_WF_GET_REQUESTDETAILS;

这是我完整的存储过程

【问题讨论】：

看来你调用的是5个参数的存储过程，请确保存储过程实际上是5个参数。

你的存储过程代码不完整

其实这里我已经添加了部分程序。现在我已经添加了整个存储过程

您似乎错过了 c# 代码中的P_OUT_TBL 参数

这并不意味着你可以在调用存储过程时从参数列表中省略它。

【参考方案1】：

您的 SP 第 2 行不应该从“P_USER_CODE varchar2”更改为“P_USER_CODE IN varchar2”吗？

【讨论】：

是的，我错过了。但在此之后我也得到了同样的错误 ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'SP_WF_GET_REQUESTDETAILS' ORA-06550: line 1, column 7: PL/SQL: Statement忽略
