Question

我正在处理一个包含2列的查询，我尝试了CAST和CONVERT，但仍然返回0.请提供帮助

SELECT a.Disposition,a.[Disposition Reason Breakdown],a.CSP,b.Total FROM
(
SELECT a.[Disposition],a.[Disposition Reason Breakdown],a.[CSP] FROM
(
SELECT [Disposition],[Disposition Reason Breakdown],COUNT(*) as CSP FROM [dbo].[Disposition]
WHERE [Disposition] <> 'Interested'
GROUP BY [Disposition],[Disposition Reason Breakdown]
) a
)a
INNER JOIN
(
SELECT a.Disposition,SUM(a.CSP) as Total FROM 
(
SELECT [Disposition],[Disposition Reason Breakdown],COUNT(*) as CSP FROM [dbo].[Disposition]
WHERE [Disposition] <> 'Interested'
GROUP BY [Disposition],[Disposition Reason Breakdown]
)a
GROUP BY a.Disposition
)b ON a.Disposition = b.Disposition
