Question

我只是想知道其他人遇到这个问题。使用Group By或时，SubSonic生成不正确的SQL 与分页不同。这是已知的错误吗？

注意使用分页时，group by是在错误的位置。

没有分页的SubSonic SQL输出：

exec sp_executesql N'SELECT [dbo].[vwMapProject].[Id], [dbo].[vwMapProject].[Name]
 FROM [dbo].[vwMapProject]
 INNER JOIN [dbo].[Product_ProductComponent] ON [dbo].[vwMapProject].[ProductId] = [dbo].[Product_ProductComponent].[ProductId]
 INNER JOIN [dbo].[ProductComponent] ON [dbo].[Product_ProductComponent].[ProductComponentId] = [dbo].[ProductComponent].[Id]
 WHERE [dbo].[ProductComponent].[ExternalId] LIKE @ExternalId0
 GROUP BY [dbo].[vwMapProject].[Id], [dbo].[vwMapProject].[Name]
',N'@ExternalId0 nvarchar(8)',@ExternalId0=N'GC767AV%'

使用分页的SubSonic SQL输出：

exec sp_executesql N'
SELECT *
FROM     (SELECT ROW_NUMBER() OVER ( ORDER BY Id) AS Row, 
 [dbo].[vwMapProject].[Id], [dbo].[vwMapProject].[Name] 
 FROM [dbo].[vwMapProject]
 INNER JOIN [dbo].[Product_ProductComponent] ON [dbo].[vwMapProject].[ProductId] = [dbo].[Product_ProductComponent].[ProductId]
 INNER JOIN [dbo].[ProductComponent] ON [dbo].[Product_ProductComponent].[ProductComponentId] = [dbo].[ProductComponent].[Id]
 GROUP BY [dbo].[vwMapProject].[Id], [dbo].[vwMapProject].[Name]
 WHERE [dbo].[ProductComponent].[ExternalId] LIKE @ExternalId0
) AS PagedResults
WHERE  Row >= 1 AND Row <= 20',N'@ExternalId0 nvarchar(8)',@ExternalId0=N'GC767AV%'

这应该在当前版本中修复 - 3.0.0.3。如果你没有它 - 请前往我们的项目网站，因为这是一个早期报告的错误，我花了一些时间试图指出它：）

使用Group By或Distinct with Paging时，SubSonic会生成不正确的SQL
