Question

I need to delete a bunch of rows from my database under a certain condition. I have the select statement to return this condition and then for each row in this select statement I need it execute an SP that will delete these rows and a load of related rows. So far I have:

select importfileid from import.importfiles where importfilestatusid < 7

and then execute

EXEC    [import].[spDeleteFromAllImportRelatedTables]
    @fileID = @importfileid

I’m just not sure how to do the inbetween? If someone could point me in the right direction that would be great.

NB: This is a once off thing. Performance is not an issue.

Answer 1

you can use a cursor:

declare @importFileID int
declare @cur cursor

set @cur = cursor fast_forward for 
select importfileid from import.importfiles where importfilestatusid < 7

open @cur
fetch next from @cur into @importFileID
while(@@fetch_status = 0)
begin
  exec [import].[spDeleteFromAllImportRelatedTables] @fileID = @importFileID
  fetch next from @cur into @importFileID
end
close @cur
deallocate @cur
