Sql server 拆分SQL server 2008并删除

我找不到如何在SQL中使用split函数的结果。它返回一个表，我不知道如何使用“foreach”这样的函数来选择每个返回数据

查看拆分函数：

ALTER FUNCTION [dbo].[Split] (@separator char(1), @value varchar(512))
RETURNS table
AS
RETURN (
    WITH Pieces(pn, start, stop) AS (
      SELECT 1, 1, CHARINDEX(@separator, @value)
      UNION ALL
      SELECT pn + 1, stop + 1, CHARINDEX(@separator, @value, stop + 1)
      FROM Pieces
      WHERE stop > 0
    )
    SELECT pn AS Id,
      SUBSTRING(@value, start, CASE WHEN stop > 0 THEN stop-start ELSE 512 END) AS Data
    FROM Pieces
  )

它返回以下内容：

@separator = ','
@value = '13,14,15'

Id Data
1  13
2  14
3  15

然后我想做这样一件事：

    DELETE FROM myTable
    WHERE  OneColumnInMyTable = @OneColumnInMyTable AND @ImportantValue = @Data

@数据对应于分割返回的每个值数据

目的是：

    foreach(Data in ReturnOfMySplitFunction)
    {
            DELETE FROM myTable
            WHERE  OneColumnInMyTable = @OneColumnInMyTable AND @ImportantValue = Data
    }

你有什么办法吗？使用sql server时是否可能？

谢谢

您可以使用拆分功能执行类似操作

DELETE
FROM myTable
WHERE OneColumnInMyTable = @OneColumnInMyTable
    AND @ImportantValue IN (
        SELECT Data
        FROM dbo.Split(',', @Data)
        )

---

在这里，我假设您的

@Data

包含如下值-

@Data='11、12、14、15'

请尝试以下脚本：

Delete  A 
FROM MYTABLE A
JOIN DBO.Split(@separator, @value) B ON B.DATA=@Data AND @ImportantValue = B.DATA
Where A.OneColumnInMyTable = @OneColumnInMyTable

如果有人想做同样的事情，我会把我的代码：

DECLARE @categories varchar(512),
        @GroupingId int,
        @Separator char

SET @Separator = ','
SET @categories = '12,24,33'
SET @GroupingId = '69241'

DELETE FROM RefAssoThematic
WHERE GroupingId = @GroupingId 
AND ThematicId IN (SELECT Data FROM
dbo.split(@Separator,@Categories))
