Question

Simple query

Asked by: amucinobluedot

I am giving 500 points cuz i need this quick, but I am sure its pretty simple. I have a query like:

Select id, userid, name, lastname

I get 100 records, but some of them have the same 'userid', i want to display them only once instead of multiple times, so I get like 50 results where the records that are repeated by the 'userid' only show once.

Select id, (userid only once), name, lastname

Hope that makes sense.

Select min(ID), userid, name, lastname
Group By userid, name, lastname

I am assuming that a UserID matches only a single name and lastname.  If otherwise, we'll have to change the aggregation  & grouping.

Try this

--Raj

SELECT ID, MIN(USERID), NAME, LASTNAME FROM YOURTABLE
GROUP BY ID, NAME, LASTNAME

One more thing, once I added the MIN I got an error saying that "Alienid" is not part of the group by clause. This is my query:

SELECT c.Id, c.CaseId, c.EmpId, MIN (c.AlienId), c.FirmAddressId, c.ExpDate,d.FirstNm, d.MiddleNm, d.LastNm ,d.email, d.Nistatus,  d.ExpiresOn, c.FirmId, c.MainCase , d.NIVMaxStatus, b.MaidenNm,e.Processcatalog,c.archived, f.Filedon, f.Approvedon, f.Validtodate
FROM Cases c  LEFT JOIN Users as d ON c.AlienID = d.UserID  INNER JOIN Processcatalog as e ON c.Process = e.ProcesscatalogID  INNER JOIN Users as b ON c.empid = b.userid LEFT JOIN Activities_Misc as f on f.act_misc_id = c.defaultrecpt
WHERE c.EmpID=MMColParam AND c.archived = 0 and c.firmid = MMColParam2
ORDER BY d.LastNm, c.caseid

 

by: DanielWilsonPosted on 2009-11-05 at 16:44:30ID: 25755753

Everything that's NOT in an aggregate (Min, Max, Avg, Sum) needs to be in the Group By clause.

SELECT c.Id, c.CaseId, c.EmpId, MIN (c.AlienId), c.FirmAddressId, c.ExpDate,d.FirstNm, d.MiddleNm, d.LastNm ,d.email, d.Nistatus,  d.ExpiresOn, c.FirmId, c.MainCase , d.NIVMaxStatus, b.MaidenNm,e.Processcatalog,c.archived, f.Filedon, f.Approvedon, f.Validtodate
FROM Cases c  LEFT JOIN Users as d ON c.AlienID = d.UserID  INNER JOIN Processcatalog as e ON c.Process = e.ProcesscatalogID  INNER JOIN Users as b ON c.empid = b.userid LEFT JOIN Activities_Misc as f on f.act_misc_id = c.defaultrecpt
WHERE c.EmpID=MMColParam AND c.archived = 0 and c.firmid = MMColParam2
GROUP BY c.Id, c.CaseId, c.EmpId, c.FirmAddressId, c.ExpDate,d.FirstNm, d.MiddleNm, d.LastNm ,d.email, d.Nistatus,  d.ExpiresOn, c.FirmId, c.MainCase , d.NIVMaxStatus, b.MaidenNm,e.Processcatalog,c.archived, f.Filedon, f.Approvedon, f.Validtodate
ORDER BY d.LastNm, c.caseid

This is the actual final query but I get an error, error is attached.

SELECT MIN (c.AlienID), d.LastNm, d.FirstNm, d.email, d.Nistatus, d.NIVMaxStatus
FROM Cases c  
LEFT JOIN Users as d ON c.AlienID = d.UserID  
INNER JOIN Users as b ON c.empid = b.userid
WHERE c.EmpID=MMColParam AND c.archived = 0 and c.firmid = MMColParam2
GROUP BY MIN (c.AlienID), d.LastNm, d.FirstNm, d.email, d.Nistatus, d.NIVMaxStatus
