拜托，我希望任何人都可以帮助我:(

Answer 1

我没用过objCmd.CommandType = CommandType.StoredProcedure;

我总是使用这种语法：

objCmd.CommandText = "BEGIN :res := TSCBE1005_PKG.TSCBE1005_001_FNC(:P_BLD_LVL_CD, :P_IN_DATE, ...); END;";
objCmd.CommandType = CommandType.Text;

那你的参数声明是错误的。

P_SECTOR_NO.Direction = ParameterDirection.Input;

ParameterDirection 必须与您的函数的签名相匹配，即ReturnValue 或Input 或Output（在您的示例中未使用）或InputOutput

类型也错了：

P_SECTOR_NO.OracleType = OracleType.VarChar;

您必须使用 OracleDbType，请参阅 OracleDbType Enumeration。有关 OracleDbType 和 .NET 类型之间的映射，请参阅C#: Oracle Data Type Equivalence with OracleDbType

顺便说一句，您可以将所有这些都放在一个命令中，例如

cmd.Parameters.Add("P_BLD_LVL_CD", OracleDbType.Varchar2, ParameterDirection.Input).Value = "R035570412";

请注意，如果是ParameterDirection.Output，您必须单独设置DbType。同样对于OracleDbType.Varchar2，您必须指定大小和初始值：

cmd.Parameters.Add("parName", OracleDbType.Varchar2, 240, null, ParameterDirection.Output);
cmd.Parameters("parName").DbType = DbType.String;

Answer 2

这看起来不对

P_BLD_LVL_CD.ParameterName = ":P_BLD_LVL_CD";
                              ^

冒号用于标识 SQL 字符串中的占位符。实际参数名称应该是

P_BLD_LVL_CD.ParameterName = "P_BLD_LVL_CD";

ParameterDirection.ReturnValue 也仅用于返回值。所以每个函数调用应该只有一个这样的参数。您似乎将它用于所有 IN OUT 参数。这是错误的。

对于 IN OUT 参数，您需要使用ParameterDirection.InputOutput。

顺便说一句，带有 IN OUT 参数的函数是糟糕的 PL/SQL 实践，但我想你对此无能为力。

所以，TSCBE1005_001_FNC 是一个接受三个 IN（只读）参数和十八个 IN OUT（读/写）参数的函数。因此您的通话需要：

• 一个参数与ParameterDirection.ReturnValue
• 三个参数用ParameterDirection.Input
• 十八个参数ParameterDirection.InputOutput
