我是 ASP.NET 和 Oracle SQL 的新手。我正在尝试创建一个长 SQL 字符串（使用UNION ALL），然后将该字符串传递给处理其余部分的数据处理程序类。这个问题肯定存在于我的 SQL 字符串中。

这是我的代码的第一部分，它运行完美：

sql = "SELECT 'DCS - HCA (81)', HCA_SENT_DCS, HCA_VALID_DCS, HCA_SUSPEND_DCS, HCA_REJECTED_DCS,"
sql &= " SUM(HCA_VALID_DCS + HCA_SUSPEND_DCS + HCA_REJECTED_DCS) As ""Total Returned"","
sql &= " RESOLVED_CNT, SUM(HCA_REJECTED_DCS - RESOLVED_CNT) As ""To Do"""
sql &= " FROM HUB_CDI_CONTROL_NBRS WHERE REPORT_DATE = :0 "
_param.Add(dateSelected.ToString("dd-MMM-yyyy"))
sql &= " GROUP BY HCA_SENT_DCS, HCA_VALID_DCS, HCA_SUSPEND_DCS, HCA_REJECTED_DCS,"
sql &= " RESOLVED_CNT"

但是，当我尝试UNION使用另一条语句执行此 SQL 时SELECT，出现以下异常：

ORA-00933: SQL command not properly ended

这是完整的代码：

sql = "SELECT 'DCS - HCA (81)', HCA_SENT_DCS, HCA_VALID_DCS, HCA_SUSPEND_DCS, HCA_REJECTED_DCS,"
sql &= " SUM(HCA_VALID_DCS + HCA_SUSPEND_DCS + HCA_REJECTED_DCS) As ""Total Returned"","
sql &= " RESOLVED_CNT, SUM(HCA_REJECTED_DCS - RESOLVED_CNT) As ""To Do"""
sql &= " FROM HUB_CDI_CONTROL_NBRS WHERE REPORT_DATE = :0 "
sql &= " GROUP BY HCA_SENT_DCS, HCA_VALID_DCS, HCA_SUSPEND_DCS, HCA_REJECTED_DCS,"
sql &= " RESOLVED_CNT"

sql &= " UNION ALL"

sql &= "SELECT 'SFDC - HCA (82)', HCA_SENT_SFDC, HCA_VALID_SFDC, HCA_SUSPEND_SFDC, HCA_REJECTED_SFDC,"
sql &= " SUM(HCA_VALID_SFDC + HCA_SUSPEND_SFDC + HCA_REJECTED_SFDC) As ""Total Returned"","
sql &= " RESOLVED_CNT, SUM(HCA_REJECTED_SFDC - RESOLVED_CNT) As ""To Do"""
sql &= " FROM HUB_CDI_CONTROL_NBRS WHERE REPORT_DATE = :0 "
sql &= " GROUP BY HCA_SENT_SFDC, HCA_VALID_SFDC, HCA_SUSPEND_SFDC, HCA_REJECTED_SFDC,"
sql &= " RESOLVED_CNT"

_param.Add(dateSelected.ToString("dd-MMM-yyyy"))
_DH.TheSQL = sql
_DT = _DH.GetTableWithParameters(_param.ToArray)

我关心这段代码的两个部分：

  1. 我是否正确调用了 _param.Add() 函数？由于我引用参数两次，使用:0，我只需要使用 _param.Add() 函数一次吗？

  2. 我觉得我错误地使用了GROUP BY语法。当我试图在不使用的情况下运行查询时，Oracle 对我大喊大叫GROUP BY，但我不确定我是否正确使用它们。本质上，我只是将每一列添加SELECTed到GROUP BY

否则，我确定我还缺少其他错误。请帮忙！

谢谢你。

sql &= " UNION ALL"
sql &= "SELECT 'SFDC - HCA (82)', HCA_SENT_SFDC, HCA_VALID_SFDC, HCA_SUSPEND_SFDC, HCA_REJECTED_SFDC,"

结果，在中间的某个地方：

... UNION ALLSELECT 'SFDC - HCA (82)', HCA_SENT_SFDC, ...

注意：“联合全选”

带有其他修复的完整代码。我不相信你真的想要 GROUP BY，加/减，你不需要 SUM() 函数。要在 UNION ALL 中有效，第一部分的所有列都必须命名/别名。

sql = "SELECT 'DCS - HCA (81)' Title, HCA_SENT_DCS, HCA_VALID_DCS, HCA_SUSPEND_DCS, HCA_REJECTED_DCS,"
sql &= " HCA_VALID_DCS + HCA_SUSPEND_DCS + HCA_REJECTED_DCS As ""Total Returned"","
sql &= " RESOLVED_CNT, HCA_REJECTED_DCS - RESOLVED_CNT As ""To Do"""
sql &= " FROM HUB_CDI_CONTROL_NBRS WHERE REPORT_DATE = :0 "
sql &= " UNION ALL "
sql &= "SELECT 'SFDC - HCA (82)', HCA_SENT_SFDC, HCA_VALID_SFDC, HCA_SUSPEND_SFDC, HCA_REJECTED_SFDC,"
sql &= " HCA_VALID_SFDC + HCA_SUSPEND_SFDC + HCA_REJECTED_SFDC As ""Total Returned"","
sql &= " RESOLVED_CNT, HCA_REJECTED_SFDC - RESOLVED_CNT As ""To Do"""
sql &= " FROM HUB_CDI_CONTROL_NBRS WHERE REPORT_DATE = :1 "

_param.Add(dateSelected.ToString("dd-MMM-yyyy"))
_param.Add(dateSelected.ToString("dd-MMM-yyyy"))  ' 2nd one
_DH.TheSQL = sql
_DT = _DH.GetTableWithParameters(_param.ToArray)
