锚点和递归部分之间的类型不匹配 "dataitem column"

Question

我在执行 sql 查询 "types don't match between the anchor and the recursive" 时遇到错误。我的查询：

;WITH FA_CTE  AS
(
SELECT
    fa.name as Data1,
    fa.lnumber as Data2,
    fa.allnumber as Data3,
    fa.productname as Data4

  FROM
   (
     SELECT      A.name, A.lnumber, A.allnumber, A.productname
FROM            soldproduct AS A INNER JOIN Account AS B ON A.account = B.accountid
) fa

)
 , tmp1(Data1, Data2, Data3, DataItem , Data4) as (
select Data1, Data2, Data3, LEFT(Data4, CHARINDEX('-',Data4+'-')-1),
STUFF(Data4, 1, CHARINDEX('-',Data4+'-'), '')
from FA_CTE
union all
select Data1, Data2, Data3, LEFT(Data4, CHARINDEX('-',Data4+'-')-1),
STUFF(Data4, 1, CHARINDEX('-',Data4+'-'), '')
from tmp1

)

select Data1, Data2, Data3, DataItem AS Data4
from tmp1
order by Data1

不要问我为什么 SQL 服务器在使用递归 CTE 时遇到字符串长度问题，但我过去通过显式转换计算字符串列解决了这个问题：

tmp1(Data1, Data2, Data3, DataItem, Data4) as (
 select Data1, Data2, Data3,
        convert(varchar(max), LEFT(Data4, CHARINDEX('-', Data4 + '-') - 1)),
        convert(varchar(max), STUFF(Data4, 1, CHARINDEX('-', Data4 + '-'), ''))
 from FA_CTE
 union all
 select Data1, Data2, Data3,
        convert(varchar(max), LEFT(Data4, CHARINDEX('-', Data4 + '-') - 1)),
        convert(varchar(max), STUFF(Data4, 1, CHARINDEX('-', Data4 + '-'), ''))
 from tmp1

锚点和递归部分之间的类型不匹配 "dataitem column"

types don't match between the anchor and the recursive part "dataitem column"
