Question

我从C＃调用我的存储过程，我得到以下异常：

ORA-06550：第1行第7栏：
  PLS-00306：调用'MY_PROC'时参数的数量或类型错误   ORA-06550：第1行第7栏：
  PLS-00306：调用'MY_PROC'时参数的数量或类型错误   ORA-06550：第1行第7栏：
  PL / SQL：忽略语句

由于我的程序有57个参数，因此要知道问题究竟在哪里并不容易。有没有办法得到更详细的信息？

注意：但参数类型和数字似乎匹配！

以下是我的存储过程参数：

这是我从c＃：

创建参数的主代码：

    public DbParameter CreateInputDbParameter(DbType typeParam, int sizeparam,
        string nameParam, object valueParam)
    {
        DbParameter DbParam = Parameter;
        DbParam.DbType = typeParam;
        DbParam.Size = sizeparam;
        DbParam.Direction = ParameterDirection.Input;
        DbParam.ParameterName = nameParam;
        if (valueParam == null)
        {
            DbParam.Value = DBNull.Value;
        }
        else
        {
            DbParam.Value = valueParam;
        }
        return DbParam;
    }

    public DbParameter CreateOutputDbParameter(DbType typeParam, int sizeparam, string nameParam)
    {
        DbParameter DbParam = Parameter;
        DbParam.DbType = typeParam;
        DbParam.Size = sizeparam;
        DbParam.Direction = ParameterDirection.Output;
        DbParam.ParameterName = nameParam;
        return DbParam;
    }

Answer 1

如果输出

，则需要将参数方向设置为ParameterDirection.Output

OracleParameter test= 
    new OracleParameter("testparameter", OracleDbType.Varchar2);
test.Direction = ParameterDirection.Output;
cmd.Parameters.Add(test);

如果是输入，则将其设置为ParameterDirection.Input

检查参数的大小，声明时不给出大小。而且参数的类型也很重要。例如，您NUMBER(15,0)映射DbType.Int32，NUMBER(3,0)映射DbType.Double

修改

您正在尝试使用ADO.NET基类连接oracle，您知道即使System.Data.OracleClient也已弃用。

不推荐使用System.Data.OracleClient中的类型。类型是在.NET Framework的第4版中受支持，但将在a中删除未来发布。 Microsoft建议您使用第三方Oracle 提供商。

您最好使用Oracle Data Provider for .NET，大部分错误都将得到解决。
