  I am using SQL 2008 and I need help to write a select query for the following output

  I need list of distinct CustId who have ordered both ProdId 1 and 4. Also if the custid has ordered ProdId 0 then that custid should not be selected

  table schema and data are given below and as per the data given the select query should display data cust1 and cust5 as both of them have ProdId 1 and 4 and also neither of them have ProdId 0.

  create table product_details

  (

  TempId int identity,

  CustId varchar(50),

  ProdId char(1),

  enteredon datetime

  )

  insert into product_details values('cust1',1,getdate())

  insert into product_details values('cust1',2,getdate())

  insert into product_details values('cust1',3,getdate())

  insert into product_details values('cust1',4,getdate())

  insert into product_details values('cust2',1,getdate())

  insert into product_details values('cust2',2,getdate())

  insert into product_details values('cust2',3,getdate())

  insert into product_details values('cust3',0,getdate())

  insert into product_details values('cust3',1,getdate())

  insert into product_details values('cust3',2,getdate())

  insert into product_details values('cust4',1,getdate())

  insert into product_details values('cust4',2,getdate())

  insert into product_details values('cust4',3,getdate())

  insert into product_details values('cust4',4,getdate())

  insert into product_details values('cust4',0,getdate())

  insert into product_details values('cust5',1,getdate())

  insert into product_details values('cust5',2,getdate())

  insert into product_details values('cust5',3,getdate())

  insert into product_details values('cust5',4,getdate())

  thanks

  Hi

  as a start, suggest you read the article below...it seems to be very clsoe to what you are asking and will explain the method far better than I can.

  http://www.sqlservercentral.com/articles/T-SQL/88244/

  if you still have issues, please post back.

  kind regards

  Something like this?

  SELECT DISTINCT

  CustId

  FROM

  (

  SELECT

  CustId

  FROM

  product_details

  WHERE

  ProdId = 1

  AND CustId IN (SELECT DISTINCT CustId FROM product_details WHERE ProdId = 4)

  EXCEPT

  SELECT CustId

  FROM

  product_details

  WHERE

  ProdId = 0

  ) AS A

  Check if the below one helps ur purpose.

  select distinct custid

  from product_details

  where prodid in (1,4) and custid not in (select custid from product_details where prodid=0)

  There's lots of ways of doing this, here's another

  SELECT CustID

  FROM product_details

  WHERE ProdId = 1

  INTERSECT

  SELECT CustID

  FROM product_details

  WHERE ProdId = 4

  EXCEPT

  SELECT CustID

  FROM product_details

  WHERE ProdId = 0;

  Also this

  WITH Summary AS (

  SELECT CustID,

  SUM(CASE WHEN ProdId = 0 THEN 1 ELSE 0 END) AS NumProdId0,

  SUM(CASE WHEN ProdId = 1 THEN 1 ELSE 0 END) AS NumProdId1,

  SUM(CASE WHEN ProdId = 4 THEN 1 ELSE 0 END) AS NumProdId4

  FROM product_details

  GROUP BY CustID)

  SELECT CustID

  FROM Summary

  WHERE NumProdId0=0 AND NumProdId1>0 AND NumProdId4>0;

  select distinct custid

  from product_details

  where prodid in (1,4) and custid not in (select custid from product_details where prodid=0)

  Nope that wont work the IN works like an OR so CustID 2 is returned in the result set..

  I have overlooked at the problem statement and gave the wrong query.

  Thanks Andy for correcting me.

  Another option:

  SELECT pd.CustID

  FROM Product_Details pd

  LEFT JOIN (SELECT CustID FROM Product_Details WHERE ProdID = 0) c ON pd.CustID = c.CustID

  WHERE pd.ProdID IN (1, 4)

  AND c.CustID IS NULL

  GROUP BY pd.CustID

  HAVING COUNT(*) = 2

  SELECT

  CustId

  FROM dbo.product_details

  GROUP BY

  CustId

  HAVING

  MAX(CASE WHEN ProdId = 0 THEN 1 ELSE 0 END) = 0 AND

  MAX(CASE WHEN ProdId = 1 THEN 1 ELSE 0 END) = 1 AND

  MAX(CASE WHEN ProdId = 4 THEN 1 ELSE 0 END) = 1

  ORDER BY

  CustId

  I came out with the same code as Jeff showed in the article, but I believe that Scott's code would be better as it is a single table scan instead of 2 or 3.

  And now call me crazy, but execution plans show one thing and time indicators show another on performance issues. Maybe is because I'm using temp tables instead of normal physical tables, but the statement with 3 table scans is performing faster than the other two. And the statement with 1 table scan is the slowest.

  Can anyone confirm or deny this?

  This is the code I used:

  --insert into #product_details

  --SELECT TOP 1000000

  --'CUST' + CAST( (ROW_NUMBER() OVER( ORDER BY (SELECT NULL)) / 4) + 6 AS varchar(10)),

  --ABS(CHECKSUM(NEWID())) % 5,

  --GETDATE()

  --FROM sys.all_columns ac1

  -- CROSS JOIN sys.all_columns ac2

  DECLARE @DATE datetime2, @dummy varchar(50)

  SET @DATE = SYSDATETIME()

  SELECT @dummy = CustId

  FROM(

  SELECT CustId

  FROM #product_details

  WHERE ProdId IN( 1,4)

  GROUP BY CustId HAVING COUNT(DISTINCT prodid) = 2

  EXCEPT

  SELECT CustId

  FROM #product_details

  WHERE ProdId = 0) t

  PRINT DATEDIFF( ns, @DATE, SYSDATETIME())

  SET @DATE = SYSDATETIME()

  SELECT @dummy = CustId

  FROM

  (SELECT CustId

  FROM #product_details

  WHERE ProdId = 1

  AND CustId IN (SELECT DISTINCT CustId FROM #product_details WHERE ProdId = 4)

  EXCEPT

  SELECT CustId

  FROM #product_details

  WHERE ProdId = 0) AS A

  PRINT DATEDIFF( ns, @DATE, SYSDATETIME())

  SET @DATE = SYSDATETIME()

  SELECT

  @dummy = CustId

  FROM #product_details

  GROUP BY

  CustId

  HAVING

  MAX(CASE WHEN ProdId = 0 THEN 1 ELSE 0 END) = 0 AND

  MAX(CASE WHEN ProdId = 1 THEN 1 ELSE 0 END) = 1 AND

  MAX(CASE WHEN ProdId = 4 THEN 1 ELSE 0 END) = 1

  ORDER BY

  CustId

  PRINT DATEDIFF( ns, @DATE, SYSDATETIME())

  SET @DATE = SYSDATETIME()

  Timing seems that way.

  I would still be leery of additional I/O vs other time, but if you are willing to scan the table 3 times to get response time, then I would say do this:

  SELECT

  CustId

  FROM #product_details pd1

  WHERE

  prodid = 1 AND

  EXISTS(SELECT 1 FROM #product_details pd2 WHERE pd2.custid = pd1.custid AND pd2.prodid = 4) AND

  NOT EXISTS(SELECT 1 FROM #product_details pd3 WHERE pd3.custid = pd1.custid AND pd3.prodid = 0)
