Question

对于列Q03Total和Q02TOTAL，我在执行时获得了无效的列名。我不确定问题出在哪里。嵌套查询正在按预期运行。

INSERT INTO LARGE_EXPOSURE_MAIN
select counterparty, CType, CParties, CStatus , CDemands, CSavings, CTime , CFinIns , CLiab,
CCp , (CDemands + CSavings + CTime + CFinIns+ CLiab + CCp ) Q03_Total , CTrn, CLoans, COnBal, COffBal,

AND (Q03Total > 0 OR Q02TOTAL > 0)

Answer 1

您对Q02Total和Q03Total的命名在一个位置上带有下划线，而在另一个位置则没有。此外，WHERE子句是定义这些字段的同一SELECT的一部分，因此它们对WHERE子句不可用。您可以在WHERE子句中用它们的值（添加在一起的字段的列表）替换它们，或将SELECT语句放在子查询中，然后在其上执行WHERE。

编辑：将其放在子查询中的示例：

INSERT INTO LARGE_EXPOSURE_MAIN
select *
from (
select counterparty, CType, CParties, CStatus , CDemands, CSavings, CTime , CFinIns , CLiab,
CCp , (CDemands + CSavings + CTime + CFinIns+ CLiab + CCp ) Q03_Total , CTrn, CLoans, COnBal, COffBal,
CNonPerf, CFunCoun, (CLoans + COnBal + COffBal + CNonPerf + CFunCoun) Q02_TOTAL
from
(
  select counterparty , dbo.Q03_get_type_of_counterparty(customerid, 'Y') CType,
  dbo.Q03_get_list_of_counterparties(customerid, 'Y') CParties ,
