Hi Skip,
Thanks for posting the code...made life much easier.
I have a stored procedure for you to try...note that I renamed #FPD_Schedule to FPD_Schedule so that the stored proc could update it...
CREATE PROC move_order @key INT,@line INT,@priority INT
AS
SET NOCOUNT ON;
-- collect the existing data for the key
DECLARE @old_priority INT,@old_line INT
SELECT @old_priority=priority,@old_line=line FROM FPD_Schedule WHERE =@key
-- move everything up on the line we are moving from
-- move everything down on the line we are moving to
-- move the specified order
UPDATE FPD_Schedule
SET priority= CASE
WHEN @key THEN @priority
ELSE
CASE
WHEN @line=@old_line THEN priority +
CASE
WHEN priority BETWEEN @priority AND @old_priority
OR priority BETWEEN @old_priority AND @priority THEN
CASE
WHEN @priority<@old_priority THEN 1
WHEN @priority>@old_priority THEN -1
ELSE 0
END
ELSE 0
END
WHEN line=@old_line AND priority>@old_priority THEN priority-1
WHEN line=@line AND priority>=@priority THEN priority+1
ELSE priority
END
END
, line = CASE
WHEN @key THEN @line
ELSE [line]
END
WHERE line=@line OR line=@old_line
It looks a bit horrific but that is just because I wanted to perform all updates in one statement - the alternative being to read /update
the table two or three times...which I wanted to avoid.
