Query containing while loop for dates taking increditbly long

  • Hi All,

    I'm hoping to get some insight to an issue we're experiencing with a query in an SSIS package, which has been taking ages to complete. It takes about 3 hours in our Dev environment, and progressively longer as we've tried deploying to the upper environments. We thought as first, it might have to do with the date variables being passed to it, but I don't believe that's the case, as I've tried running the package with just a week spanning between the dates, and it's taking an hour plus. Granted that the date range is pretty long, i.e. about 10 years, but I don't think it should be taking this long....our last attempt to deploy to Prod took it over 10 hours before it had to be cancelled and rolled back. Any insight that could be provided would be greatly appreciated. I'm including the query below:

    DECLARE @StartDate DateTime = '2010-01-01'
    DECLARE @EndDate DateTime = '2019-05-01'

    DECLARE @StartDT DATETIME
    DECLARE @EndDT DATETIME
    DECLARE @LoopEndDT DATETIME
    DECLARE @PeriodStart DateTime
    DECLARE @PeriodEnd DateTime
    DECLARE @RunMonth INT

    -- get last day of month
    SET @StartDT = DATEADD(mm, DATEDIFF(mm, 0,@StartDate) +1, -1)
    PRINT @StartDT

    SET @LoopEndDT = @EndDate
    PRINT @LoopEndDT

    -- Loop through end of month days
    WHILE @StartDT < @LoopEndDT
    BEGIN
    SET @EndDT = DATEADD(DAY,1,@StartDT);
    --SET @EndDT = DATEADD(MONTH,1,@StartDT);
    SET @PeriodStart = DATEADD(MONTH, -1, @StartDt);
    SET @PeriodEnd = DATEADD(ms, -3, @StartDt);
    SET @RunMonth = convert(int, substring(CONVERT(char(10), @StartDT, 112),1,6));

    -- Create a list by last day of month for each Enrollment ID that has coverage that day, no record means no coverage
    -- Active coverage means the effective date is before the *end* of the last day of the month (23:59:59), and the end date is after the *beginning* of the last day of the month (00:00:00)
    -- Pull the MAX asset value for those cases where the dates overlap (to prevent pulling multiple records)

  • Well how long does your process take to run for a single month?  It's going to take ~113 times longer to run for 9 and a half years.

     

    Other than that it looks like one of those inserts has a bunch of sub queries in the select, maybe try working on that.

    • You have non-SARGable formulas in your WHERE clause.
    • You call the same table multiple times when you probably only need to call it once.
    • You haven't posted the execution plan.

    Also, you have to remember that this is a volunteer website.  The longer your script is, the less likely people are to work on it.

  • Unless I am completely missing something, this is inside a loop that sets the values of a series of date variables that are never used in the query. For every execution in the loop, you are going to get the same results over and over.  If you are trying to restrict the results to a date range, then you do not need a loop.  You can simply add to the WHERE clause, although I am not sure what part of this I would add it to!

    You are using DISTINCT in the same query as a GROUP BY.  This is redundant.  Remove the DISTINCT.

    You are using MAX datatypes in your temp tables.  Unless the source columns are MAX types, then these should probably be changed.  If the source columns ARE max datatypes, then THEY should probably be changed.

    You are using the syntax WHERE something IN (SELECT something FROM Table GROUP BY).  You do not need the group by when you are using IN

    The CTE "unique_results" is using a group by, which makes it unique, and then your select on this is using DISTINCT. Again, this is redundant and is overhead that you do not need.

    The multiple in-line queries of the table ExtFSEPercentPremiumReported are not needed.  Join to this table once, and use case statements to get the values you want.

    Can you save the ACTUAL execution plan, and provide some additional details of what you need?  The table structures, sample data, and desired output would help significantly.

  • I very briefly read that script (as Drew said, the longer the script the less likely people are to look at it), but if you are trying to create a set of dates a WHILE loop is literally the worst way you can do it. I would strongly suggest building a Calendar Table (a Google or searching on this site will explain what those are), or using a Tally Table (which you could also use to build said Calendar Table).

    As a quick example, here's 2 queries that produce every date between 01 January 1900 and the current date; notice which one is faster:

    DECLARE @Dates table (CalendarDate date);
    DECLARE @StartDate date = '19000101';

    DECLARE @StartTime datetime2(7) = SYSDATETIME();

    WHILE @StartDate < GETDATE() BEGIN

    INSERT INTO @Dates (CalendarDate)
    VALUES(@StartDate);

    SET @StartDate = DATEADD(DAY, 1,@StartDate);

    END;
    SELECT *
    FROM @Dates;

    PRINT CONCAT(N'While Loop Time Taken = ', DATEDIFF(ms, @StartTime, SYSDATETIME()), N'ms');
    GO

    DECLARE @StartDate date = '19000101';

    DECLARE @StartTime datetime2(7) = SYSDATETIME();

    WITH N AS(
    SELECT N
    FROM (VALUES(NULL),(NULL),(NULL),(NULL),(NULL),(NULL),(NULL),(NULL),(NULL),(NULL))N(N)),
    Tally AS(
    SELECT ROW_NUMBER () OVER (ORDER BY (SELECT NULL)) -1 AS I
    FROM N N1, N N2, N N3, N N4, N N5), --100000 rows
    Dates AS(
    SELECT DATEADD(DAY, T.I, @StartDate) AS CalendarDate
    FROM Tally T)
    SELECT CalendarDate
    FROM Dates D
    WHERE D.CalendarDate < GETDATE()

    PRINT CONCAT(N'Tally Table Time Taken = ', DATEDIFF(ms, @StartTime, SYSDATETIME()), N'ms');

    Output messages:

    (43608 rows affected)
    While Loop Time Taken = 3203ms

    (43608 rows affected)
    Tally Table Time Taken = 125ms

  • and I'm not even sure the code is doing what they expect

    just a small example.

    the following inline query is summing the value of the outside table and has a group by within it - I would expect that the value being summed would be PPR7.MonthlyEarnedPremium

    not only that but on this case that inner "group by" is not required

    but the whole query should be rewritten

    ,(SELECT SUM(ppr.MonthlyEarnedPremium)
    FROM ExtFSEPercentPremiumReported AS ppr7
    WHERE ppr.Sourceid = ppr7.sourceID
    AND ppr.SourceCoveragePeriod = ppr7.SourcecoveragePeriod
    AND ppr7.ReportDateYearMonth <= ppr.reportDateYearMonth
    AND PPR.PCMCoverageid = ppr7.PCMCoverageid
    GROUP BY ppr7.Sourceid, ppr7.SourceCoveragePeriod, ppr7.PcmCoverageId) AS MTDEarnedPremium


    FROM ExtFSEInvoicePolicy ip

  • Wow...thank you, everyone for all of your valuable feedback! It's very much appreciated! I meant to apologize for the rather lengthy query, but I was desperate to get some insight. In the interim, we were able to get the query to optimally perform and it has gone down from at least 6 hours to mere minutes! All set to release to production, knock on wood! I'll include what it is now below. Thanks again, everyone for all of your helpful suggestions!
