How can I execute the results of my select query. The query below gives me some SQL statements back as result. I want to execute does statements, how to do this? All this is executed in SQL Sever Management Studio.
Query:
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
)
Result:
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

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
