Question

我已经创建了一个临时表，要填充记录。

这是我的查询：

create table #temp(companysitetankid int, [SourceGradeName] varchar(50), SiteCode varchar(50));

;with cst  as (
    select companysitetankid,[SourceGradeName], SiteCode,
           row_number() over (partition by [SourceGradeName] order by [TankNumber] ) rn
    from [DataManagement_DB].[dbo].[CompanySiteTank]  where CompanyCode='Aaaa'
 )
 select * from cst where  rn >1

 insert into #temp
 select companysitetankid,[SourceGradeName], SiteCode from cst

我在这里得到表cst无效。

无效的对象名称'cst'。

上述查询中我在做什么错事？

Answer 1

一旦cst语句中使用了别名为SELECT的CTE，就无法再次使用它。这可能就是您打算做的：

WITH cst AS (
    SELECT companysitetankid, [SourceGradeName], SiteCode,
       ROW_NUMBER() OVER (PARTITION BY [SourceGradeName] ORDER BY [TankNumber]) rn
    FROM [DataManagement_DB].[dbo].[CompanySiteTank]
    WHERE CompanyCode = 'Aaaa'
)

INSERT INTO #temp
SELECT companysitetankid, [SourceGradeName], SiteCode
FROM cst
WHERE rn > 1;

如果您确实需要运行该select来检查返回的内容，请在侧面运行它，但是在插入中实际使用它时将其删除。

您可以在一条语句中完成所有操作：

with cst as (
      select companysitetankid, [SourceGradeName], SiteCode,
             row_number() over (partition by [SourceGradeName] order by [TankNumber] ) rn
      from [DataManagement_DB].[dbo].[CompanySiteTank]
      where CompanyCode='Aaaa'
     )
insert into #temp
    select companysitetankid,[SourceGradeName], SiteCode 
    from cst  
    where rn > 1;

注意：使用insert时，您应该列出所有要插入的列。

如何在SQL中使用; with命令将记录插入到temptable中？
