我需要T-SQL用于以下伪代码：

SELECT BillToName，SUM（总计*，无论状态是“Y”还是“N”）WHERE Current ='Y'

随意提问。谢谢！

Answer 1

我认为你的意思是：

SELECT BillToName, SUM(Total) 
FROM Table
WHERE BillToName IN (SELECT BillToName FROM Table WHERE Current = 'Y')
GROUP BY BillToName

Answer 2

SELECT a.BillToName, b.Total
FROM TableA a
CROSS APPLY (SELECT SUM(Total) Total FROM TableA) b
WHERE Current = 'Y'

Answer 3

select billtoname,(select sum(total) from table)
where current='Y'
