Question

在这个sql server存储过程中查询

SELECT HireResponseID,
       HireResponse,
       DateResponse,
       Comments,
       YearFileOpened,
       file_number,
       isCaseOpen,
       last_update,
       isConfidential,
       date_created,
       OurClient,
       TheirClient,
       ProjectName,
       description,
       lawyer_lastname,
       lawyer_firstname,
       Conflicts.ConflictID
FROM Hire_Response,
     Conflicts,
     Lawyers
WHERE Hire_Response.ConflictID=Conflicts.ConflictID
  AND Lawyers.lawyerID=Conflicts.lawyerID
  AND firmID = @FirmID
  AND HireID IN @HireID
  AND isStillaConflict = 1
ORDER BY file_number,
         TheirClient,
         OurClient,
         lawyer_lastname,
         lawyer_firstname

参数@HireID是一个逗号分隔的整数字符串（它周围没有括号）。我想检查HireID字符串中是否有@HireID整数。但我不知道如何解析这个。

有人可以帮忙吗？

Answer 1

如果我理解你的问题，你想找到HireID在列表@HireID中的行。如果HireID是一致的长度，并且列表是分隔的，那么您可以使用：

AND @HireID LIKE '%'+CAST(HireID AS VARCHAR(5))+'%'

你也可以使用CHARINDEX：

AND CHARINDEX(HireID,@HireID) > 0

编辑：要考虑长度不一致，您可以使用：

AND (@HireID LIKE '%'+CAST(HireID AS VARCHAR(5))+',%'
    OR @HireID LIKE '%,'+CAST(HireID AS VARCHAR(5))+'%')

Answer 2

试试这个 -

DECLARE @HireID VARCHAR(100)
SELECT @HireID = '2,18'

;WITH cte AS 
(
    SELECT ID = t.c.value('.', 'INT')
    FROM (
        SELECT txml = CAST('<t>' + REPLACE(@HireID, ',', '</t><t>') + '</t>' AS XML)
    ) a
    CROSS APPLY txml.nodes('/t') AS t(c)
)
SELECT *
FROM Hire_Response
JOIN Conflicts ON Hire_Response.ConflictID = Conflicts.ConflictID
JOIN Lawyers ON Lawyers.lawyerID = Conflicts.lawyerID
WHERE firmID = @FirmID
    AND isStillaConflict = 1
    AND HireID in (SELECT ID FROM cte) 
ORDER BY file_number, TheirClient, OurClient, lawyer_lastname, lawyer_firstname

如何在sql server中发送逗号分隔的整数字符串作为参数列表？
