从C#到OracleCommand的SQL命令给出无效字符错误

下面是我试图在C代码中使用oracle连接字符串运行的命令，一切正常（相同的查询在toad中平稳运行）。但是，在填充数据集时，会出现错误ORA-00911：无效字符。我不明白为什么，请帮忙

 OracleCommand cmd = new OracleCommand(
            "SELECT DSAT.ORGANIZATION_ID, APPS.DAW_INV_ORG_NAME(DSAT.ORGANIZATION_ID) ORGANIZATION_NAME,APPS.DAW_CAT_NAME(MC.SEGMENT4) PRODUCT,TRUNC(NVL(DSAT.SCH_END_DATE,DSAT.SCH_START_DATE)) TRANSACTION_DATE,"
            +"TO_CHAR(NVL(DSAT.SCH_END_DATE,DSAT.SCH_START_DATE),'MM-YYYY') MONTH,DSAT.ITEM_SEGMENTS ITEM_CODE, DSAT.ITEM_DESCRIPTION,"
            +"DSAT.CURRENT_FORECAST_QUANTITY PLAN_QTY FROM APPS.DAW_SCPDB_ASCP_TPP_V   DSAT,APPS.MTL_ITEM_CATEGORIES   MIC,"
            +"APPS.MTL_CATEGORIES      MC"
        + " WHERE NVL(SCH_END_DATE,SCH_START_DATE) BETWEEN TO_DATE(@vfrom,'dd/mm/yyyy') AND TO_DATE(@vto,'dd/mm/yyyy')"+
            " AND  MIC.CATEGORY_SET_ID=1100000061 AND  MC.CATEGORY_ID=MIC.CATEGORY_ID AND  DSAT.INVENTORY_ITEM_ID=MIC.INVENTORY_ITEM_ID"
            +" AND  DSAT.ORGANIZATION_ID=MIC.ORGANIZATION_ID"
            +" AND DSAT.FORECAST_SET IN (@vForecastSetDPL1,@vForecastSetDPL2,@vForecastSetURIL)"
            +" AND APPS.DAW_CAT_NAME(MC.SEGMENT4) ='MICRO WAVE OVEN';", con);
        cmd.Parameters.Add("@vfrom",OracleDbType.Varchar2).Value= vfrom;
        cmd.Parameters.Add("@vto",OracleDbType.Varchar2).Value= vto;
        cmd.Parameters.Add("@vForecastSetDPL1", OracleDbType.Varchar2).Value=vForecastSetDPL1;
        cmd.Parameters.Add("@vForecastSetDPL2",OracleDbType.Varchar2).Value=vForecastSetDPL2;
        cmd.Parameters.Add("@vForecastSetURIL",OracleDbType.Varchar2).Value= vForecastSetURIL;

        cmd.CommandType = CommandType.Text;

所有使用的变量都是字符串类型，因此我必须使用date来表示日期。其余参数应该是字符串类型。

我们可以先生成查询，然后执行它，而不是发送参数。在您的代码中，

“微波炉”中不需要分号；“

编辑 对代码的更改。我没有使用真实数据进行测试

发布错误如果这些解决方案不适用于您

您的问题是在查询中使用“@”，但对于Oracle，您需要使用“：”

---

要使用存储过程，您需要创建返回sys_refcursor的输出参数，一切都应该正常

这里有一个想法…为什么不将其转换为存储过程，这样您就不必担心所有这些问题

动态构建混乱

首先要做的事情：使用参数化SQL，而不是包含direc值@DJKRAZE：只使用参数化SQL（可能还有逐字字符串文字）在这里会有很大的不同。@DJKRAZE:这是我第一次尝试，但在花了几个小时来解决“如何读取c#中的引用游标输出”问题后，我决定放弃存储过程并使用查询。@user1451836-这不是用新代码测试的--

（“@vForecastSetDPL1”，“@vForecastSetDPL2”，“@vForecastSetURIL”）

应该是

（@vForecastSetDPL1、@vForecastSetDPL2、@vForecastSetURIL）

如果查询参数化正确。我确实在存储过程和参数中添加了refcursor，但我无法将数据存储在数据集中。如果使用ODP.NET，使用ODP.NET对象检索游标并填充数据集或数据表应该不会有问题。
