我在变量中指定了值@ var1 =' 3,5,6,8'。我有一个表,其中列有一些随机数组合,以逗号分隔。 PFB样本表
我需要除了Id 3以外的所有表值,因为它的组合中有9个' 3,9,8'。
我想得到如下答案。
预期输出应仅包含ID 1,2和4.
原因是,@ var1中存在的任何/所有值都应该出现在Nos中,并且它不应该具有@ var1中不存在的no。 Id 3是后一种情况的一个例子,它包含9,它不是@ var1的一部分。
我的输出应该有1,2和4而不是3。
请你提出一些想法吗?

你可以转换为xml并使用xquery:
Sub qwerty()
Dim N As Long
N = Cells(Rows.Count, "A").End(xlUp).Row
Range("A1:I" & N).Select
End Sub

这仍然可以进一步减少,但想法如下,
创建一个SplitString函数,
CREATE FUNCTION SplitString
(
@Input NVARCHAR(MAX),
@Character CHAR(1)
)
RETURNS @Output TABLE (
Item NVARCHAR(1000)
)
AS
BEGIN
DECLARE @StartIndex INT, @EndIndex INT
SET @StartIndex = 1
IF SUBSTRING(@Input, LEN(@Input) - 1, LEN(@Input)) <> @Character
BEGIN
SET @Input = @Input + @Character
END
WHILE CHARINDEX(@Character, @Input) > 0
BEGIN
SET @EndIndex = CHARINDEX(@Character, @Input)
INSERT INTO @Output(Item)
SELECT SUBSTRING(@Input, @StartIndex, @EndIndex - 1)
SET @Input = rtrim(ltrim(SUBSTRING(@Input, @EndIndex + 1, LEN(@Input))))
END
RETURN
END
GO
使用以下一系列查询并对其进行自定义
DECLARE @t TABLE (ID INT, Nos VARCHAR(8000))
INSERT @t
VALUES (1,
'5, 3'), (2,
'3, 6, 8'), (3,
'3, 9, 8'),(4,
'8') IF OBJECT_ID('tempdb..#Temp') IS NOT NULL
DROP TABLE #Temp
SELECT * INTO #Temp
FROM
(SELECT ID,
LTRIM(RTRIM(m.n.value('.[1]','varchar(8000)'))) AS Nos
FROM
(SELECT ID,
CAST('<XMLRoot><RowData>' + REPLACE(Nos,',','</RowData><RowData>') + '</RowData></XMLRoot>' AS XML) AS x
FROM @t)t CROSS APPLY x.nodes('/XMLRoot/RowData')m(n)) P
SELECT '3, 5, 6, 8'
SELECT '(1==> 5, 3), (2==> 3, 6, 8), (3 ==> 3, 9, 8),(4 ==> 8)'
SELECT *
FROM #Temp
SELECT Item
FROM dbo.SplitString('3, 5, 6, 8', ',')
SELECT '-- Group By '
SELECT Id,
Count(Nos) C
FROM #Temp
GROUP BY Id
SELECT Id,
Count(Nos) C
FROM
(SELECT Item
FROM dbo.SplitString('3, 5, 6, 8', ',')) X
JOIN
(SELECT Id,
Nos
FROM #Temp) Y ON X.Item = Y.Nos
GROUP BY Id
SELECT '-- Final check'
SELECT T.*
FROM
(SELECT Id,
Count(Nos) C
FROM #Temp
GROUP BY Id) P
JOIN
(SELECT Id,
Count(Nos) C
FROM
(SELECT Item
FROM dbo.SplitString('3, 5, 6, 8', ',')) X
JOIN
(SELECT Id,
Nos
FROM #Temp) Y ON X.Item = Y.Nos
GROUP BY Id) Q ON P.Id = Q.Id
AND P.C = Q.C
JOIN #Temp T ON T.Id = P.Id
