SELECT 문의 결과를 실행합니다

Question

내 선택 쿼리의 결과를 어떻게 실행할 수 있습니까?아래의 쿼리는 일부 SQL 문을 결과로 다시 만듭니다.나는이 작업을 수행하는 방법을 실행하고 싶습니다.이 모든 것은 SQL Sever Management Studio에서 실행됩니다.

쿼리 :

SELECT 'UPDATE Rolecopy SET PartofFT = ''' + R2.PlayedbyOT + ''', OriginalOT = ''' + R.PlayedbyOT + ''' WHERE RoleNo = ' + CAST(R.RoleNo AS VARCHAR) + CHAR(13)
FROM Role R INNER JOIN Role R2
ON R.PartofFT = R2.PartofFT AND R.RoleNo <> R2.RoleNo
WHERE EXISTS (
    SELECT PG.RoleNo
    FROM V_PurposeGrouping PG
    WHERE R.PartofFT = PG.PartofFT
    AND R.RoleNo <> PG.RoleNo
)

.

결과 :

UPDATE Rolecopy SET PartofFT = 'Student', OriginalOT = 'Teacher' WHERE RoleNo = 5.00
UPDATE Rolecopy SET PartofFT = 'Project', OriginalOT = 'Teacher' WHERE RoleNo = 8.00
UPDATE Rolecopy SET PartofFT = 'Project', OriginalOT = 'description' WHERE RoleNo = 10.00
UPDATE Rolecopy SET PartofFT = 'Student', OriginalOT = 'Project' WHERE RoleNo = 15.0

Answer 1

Try using your first query to open a cursor, then within the loop execute the result string as dynamic SQL.

declare commands cursor for
SELECT 'UPDATE Rolecopy SET PartofFT = ''' + R2.PlayedbyOT + ''', OriginalOT = ''' + R.PlayedbyOT + ''' WHERE RoleNo = ' + CAST(R.RoleNo AS VARCHAR) + CHAR(13)
FROM Role R INNER JOIN Role R2
ON R.PartofFT = R2.PartofFT AND R.RoleNo <> R2.RoleNo
WHERE EXISTS (
    SELECT PG.RoleNo
    FROM V_PurposeGrouping PG
    WHERE R.PartofFT = PG.PartofFT
    AND R.RoleNo <> PG.RoleNo
)

declare @cmd varchar(max)

open commands
fetch next from commands into @cmd
while @@FETCH_STATUS=0
begin
  exec(@cmd)
  fetch next from commands into @cmd
end

close commands
deallocate commands

Try using this :

SELECT 'UPDATE Rolecopy SET PartofFT = ''' + R2.PlayedbyOT + ''', OriginalOT = ''' + R.PlayedbyOT + ''' WHERE RoleNo = ' + CAST(R.RoleNo AS VARCHAR) + CHAR(13)
FROM Role R INNER JOIN Role R2
ON R.PartofFT = R2.PartofFT AND R.RoleNo <> R2.RoleNo
WHERE EXISTS (
    SELECT PG.RoleNo
    FROM V_PurposeGrouping PG
    WHERE R.PartofFT = PG.PartofFT
    AND R.RoleNo <> PG.RoleNo
)
FOR XML PATH ('')

For which the result is going into one string column:

UPDATE Rolecopy SET PartofFT = 'Student', OriginalOT = 'Teacher' WHERE RoleNo = 5.00
UPDATE Rolecopy SET PartofFT = 'Project', OriginalOT = 'Teacher' WHERE RoleNo = 8.00
UPDATE Rolecopy SET PartofFT = 'Project', OriginalOT = 'description' WHERE RoleNo = 10.00
UPDATE Rolecopy SET PartofFT = 'Student', OriginalOT = 'Project' WHERE RoleNo = 15.0

All in the same column.
