Yoh*_*urg 5 sql-server cte t-sql sql-server-2008-r2
我正在尝试编写一个 CTE 查询，这对我来说可能是最高级的查询。（使用 SQL 已经 3 周了）。当我尝试运行此查询时，出现错误
消息 252，级别 16，状态 1，第 4 行递归公用表表达式“Sixer”不包含顶级 UNION ALL 运算符。
所以这里是瘦 - 我包括 DDL（这是巨大的）并且还说明 table Fiver 和 table first 看起来相同，但它们是不同的，因为 first 可能包含不存在于 Fiver 中的 acctNum，反之亦然。现在这里是 DDL

错误是由于此 CTE：
WITH Sixer As
(
Select
DISTINCT(Doctor) As Doctor
,Practice
,AnnRev
FROM Sixer -- the error occurs here
)
您有一个名为的表Sixer和一个名为 的 cte Sixer。因此，当查询解析器读取 时FROM Sixer，它会考虑 cte（而不是表）。这是不允许的 - 除非它是递归 CTE（因此是错误）。
解决方案很简单：将 CTE 名称更改为其他名称：
WITH Six As -- CTE name changed
(
SELECT DISTINCT
Doctor
,Practice
,AnnRev
FROM Sixer
)
---
---
LEFT JOIN Six sx -- and used here
---
另一种解决方案是使用模式名称 ( dbo.Sixer)引用（前缀）表。这样您就可以为 CTE 保留相同的名称：
WITH Sixer AS
(
SELECT DISTINCT
Doctor
,Practice
,AnnRev
FROM dbo.Sixer -- table name prefixed with schema
)
--- -- no other change
与错误无关，我删除了Doctor. DISTINCT不是函数。它适用于整个SELECT列表。
