Semicolon in SQL Query

Question

Hi,
I've encountered numerous problems when having a semicolon at the end of a SQL Query report. I can't see the advantage of letting the user have this. Would it be possible in future versions of APEX to either remove it, if applicable, or throw an error?
Thank you.
Martin

I expect this to give what you are looking for, but I am not sure that this is the most effecient solution. That depends on the full nature of your actual problem.
DECLARE @myTable Table (Category TIME, CalculatedSchedPax SMALLINT, Differncegreater SMALLINT)
INSERT INTO @myTable
SELECT '6:00', NULL, 0 UNION ALL
SELECT '7:00', 227, 27 UNION ALL
SELECT '8:00', NULL, 0 UNION ALL
SELECT '9:00', 106, 0 UNION ALL
SELECT '10:00', NULL, 0 UNION ALL
SELECT '11:00', 106, 0 UNION ALL
SELECT '12:00', 117, 0 UNION ALL
SELECT '13:00', 441, 241 UNION ALL
SELECT '14:00', 117, 0 UNION ALL
SELECT '15:00', 726, 526 UNION ALL
SELECT '16:00', 284, 84
WHILE EXISTS (SELECT *
              FROM   @myTable
              WHERE  CalculatedSchedPax > 200
                AND  Category <(SELECT MAX(Category) FROM @myTable))
BEGIN
   ; WITH CTE AS  (
       SELECT CalculatedSchedPax, Category,
              isnull(LAG(CalculatedSchedPax)OVER(ORDER BY Category), 0) AS PrevValue
       FROM   @myTable
   ), CTE2 AS (
       SELECT CalculatedSchedPax, Category,
              CASE WHEN PrevValue > 200 THEN PrevValue - 200 ELSE 0 END FromPrev
       FROM CTE
   UPDATE CTE2
   SET    CalculatedSchedPax = CASE WHEN CalculatedSchedPax IS NULL THEN 0
                                    WHEN CalculatedSchedPax < 200 OR
                                         Category = (SELECT MAX(Category) FROM @myTable)
                                       THEN CalculatedSchedPax
                                    ELSE 200
                               END  + FromPrev
END
SELECT * FROM @myTable
