Is it possible with SQL to combine 2 Select statements results together in one temp table.

I have 2 Select statements on a View (vReportData). I've done them separately as I thought it would be too complex to do them together.  However, I need the results of both SELECT statements to be combined for my report.  Is there a way to execute both these select statements but displaying the results in one temporary table so I can use the temp table for my report (in ASP.Net).  Both my SELECT statements are as follows:

SELECT
    Port, Boat,
    SUM(CASE WHEN Product_Name = 'Lobsters' THEN ProductKiloQty ELSE 0 END) AS [LobstersKG],
    SUM(CASE WHEN Product_Name LIKE '%Crabs' THEN ProductKiloQty ELSE 0 END) AS [CrabsKG],
    SUM(CASE WHEN Product_Name LIKE 'Velvet Crabs%' THEN ProductKiloQty ELSE 0 END) AS [VelvetsKG],
    SUM(CASE WHEN Product_Name LIKE 'Langoustine%' THEN ProductKiloQty ELSE 0 END) AS [LangKG],
    SUM(CASE WHEN Product_Name = 'Crabs (Cut)' THEN ProductKiloQty ELSE 0 END) AS [CutCrKG]
FROM vReportData
WHERE Landing_Day = 5
AND DateOfCatch BETWEEN DATEADD(day, - 8, @EndDate) AND DATEADD(day, - 1, @EndDate)
GROUP BY
    Port, Boat
ORDER BY --optional, of course
    Port, Boat
      RETURN

Then the same except Landing_Day = 6:

      SELECT
    Port, Boat,
    SUM(CASE WHEN Product_Name = 'Lobsters' THEN ProductKiloQty ELSE 0 END) AS [LobstersKG],
    SUM(CASE WHEN Product_Name LIKE '%Crabs' THEN ProductKiloQty ELSE 0 END) AS [CrabsKG],
    SUM(CASE WHEN Product_Name LIKE 'Velvet Crabs%' THEN ProductKiloQty ELSE 0 END) AS [VelvetsKG],
    SUM(CASE WHEN Product_Name LIKE 'Langoustine%' THEN ProductKiloQty ELSE 0 END) AS [LangKG],
    SUM(CASE WHEN Product_Name = 'Crabs (Cut)' THEN ProductKiloQty ELSE 0 END) AS [CutCrKG]
FROM vReportData
WHERE Landing_Day = 6
AND DateOfCatch BETWEEN DATEADD(day, - 8, @EndDate) AND DATEADD(day, - 1, @EndDate)
GROUP BY
    Port, Boat
ORDER BY --optional, of course
    Port, Boat
      RETURN

why not just add the Landing_Day criteria to the group by ?

   SELECT
    Port, Boat, Landing_Day,
    SUM(CASE WHEN Product_Name = 'Lobsters' THEN ProductKiloQty ELSE 0 END) AS [LobstersKG],
    SUM(CASE WHEN Product_Name LIKE '%Crabs' THEN ProductKiloQty ELSE 0 END) AS [CrabsKG],
    SUM(CASE WHEN Product_Name LIKE 'Velvet Crabs%' THEN ProductKiloQty ELSE 0 END) AS [VelvetsKG],
    SUM(CASE WHEN Product_Name LIKE 'Langoustine%' THEN ProductKiloQty ELSE 0 END) AS [LangKG],
    SUM(CASE WHEN Product_Name = 'Crabs (Cut)' THEN ProductKiloQty ELSE 0 END) AS [CutCrKG]
FROM vReportData
WHERE Landing_Day in (5, 6)
AND DateOfCatch BETWEEN DATEADD(day, - 8, @EndDate) AND DATEADD(day, - 1, @EndDate)
GROUP BY
    Port, Boat, Landing_Day
ORDER BY --optional, of course
    Port, Boat, Landing_Day

Use a union.

SELECT
    Port, Boat,
    SUM(CASE WHEN Product_Name = 'Lobsters' THEN ProductKiloQty ELSE 0 END) AS [LobstersKG],
    SUM(CASE WHEN Product_Name LIKE '%Crabs' THEN ProductKiloQty ELSE 0 END) AS [CrabsKG],
    SUM(CASE WHEN Product_Name LIKE 'Velvet Crabs%' THEN ProductKiloQty ELSE 0 END) AS [VelvetsKG],
    SUM(CASE WHEN Product_Name LIKE 'Langoustine%' THEN ProductKiloQty ELSE 0 END) AS [LangKG],
    SUM(CASE WHEN Product_Name = 'Crabs (Cut)' THEN ProductKiloQty ELSE 0 END) AS [CutCrKG]
FROM vReportData
WHERE Landing_Day = 5
AND DateOfCatch BETWEEN DATEADD(day, - 8, @EndDate) AND DATEADD(day, - 1, @EndDate)
GROUP BY
    Port, Boat

UNION ALL

      SELECT
    Port, Boat,
    SUM(CASE WHEN Product_Name = 'Lobsters' THEN ProductKiloQty ELSE 0 END) AS [LobstersKG],
    SUM(CASE WHEN Product_Name LIKE '%Crabs' THEN ProductKiloQty ELSE 0 END) AS [CrabsKG],
    SUM(CASE WHEN Product_Name LIKE 'Velvet Crabs%' THEN ProductKiloQty ELSE 0 END) AS [VelvetsKG],
    SUM(CASE WHEN Product_Name LIKE 'Langoustine%' THEN ProductKiloQty ELSE 0 END) AS [LangKG],
    SUM(CASE WHEN Product_Name = 'Crabs (Cut)' THEN ProductKiloQty ELSE 0 END) AS [CutCrKG]
FROM vReportData
WHERE Landing_Day = 6
AND DateOfCatch BETWEEN DATEADD(day, - 8, @EndDate) AND DATEADD(day, - 1, @EndDate)
GROUP BY
    Port, Boat
ORDER BY --optional, of course
    Landing_Day, Port, Boat

Oops sorry Geert_Gruwez my code for Landing_Day = 6 should have read:

AND DateOfCatch BETWEEN DATEADD(day, - 8, @EndDate) AND @EndDate) so they need to display different date ranges.  I think Union should work so thanks lsavidge - will try that now.

RETURN

Can someone please tell me what's wrong with this syntax??

What does this give ?

SELECT Landing_Day, Port, Boat, 
    SUM(CASE WHEN Product_Name = 'Lobsters' THEN ProductKiloQty ELSE 0 END) AS [LobstersKG],
    SUM(CASE WHEN Product_Name LIKE '%Crabs' THEN ProductKiloQty ELSE 0 END) AS [CrabsKG],
    SUM(CASE WHEN Product_Name LIKE 'Velvet Crabs%' THEN ProductKiloQty ELSE 0 END) AS [VelvetsKG],
    SUM(CASE WHEN Product_Name LIKE 'Langoustine%' THEN ProductKiloQty ELSE 0 END) AS [LangKG],
    SUM(CASE WHEN Product_Name = 'Crabs (Cut)' THEN ProductKiloQty ELSE 0 END) AS [CutCrKG]
FROM 
  (
  SELECT
      Landing_Day, Port, Boat, ProductKiloQty, Product_Name
  FROM vReportData
  WHERE (Landing_Day = 5 AND DateOfCatch BETWEEN DATEADD(day, - 8, @EndDate) AND DATEADD(day, - 1, @EndDate)
    OR (Landing_Day = 6 AND DateOfCatch BETWEEN DATEADD(day, - 8, @EndDate) AND @EndDate)
  ) As X
GROUP BY
    Landing_Day, Port, Boat
ORDER BY 
  Landing_Day, Port, Boat

Thanks - that looks like it would work too but I'm getting an error near 'AS x'.

The 'UNION ALL' method works if I take out the first 'ORDER BY' statement :-)

Hello Lorna70,

From what I've always seen in TSQL, your 2 select statements are basically tables in the FROM clause.

Put a Select statement above:

SELECT field1, field2, field3 FROM
(
{Your first select statement}
UNION ALL
{Your second select statement}
)
GROUP BY
ORDER BY


Also, remove all GROUP BY and ORDER BY clauses that are within the UNION section and put them at the end as shown above.

Thanks,
Chris
