  Hi All,

  Is it possible to combine two rows into a single row?

  example:

  Asset ID Asset Name Relationship Company

  1234 abcd Incident

  1234 abcd zxcv

  I am getting this through a Union of 2 select queries.

  Need both of them in a single row:

  1234 abcd Incident zxcv

  Basically, its something like

  select 'a' as column1, ' ' as column2

  union

  select ' ' as column1, 'b' as column2

  final result should be something like

  column1 column2

  a b

  Try this

  SELECT AssetID, AssetName, MAX(Relationship) AS Relationship, MAX(Company) AS Company

  FROM myTable

  GROUP BY AssetID, AssetName

  Try this

  SELECT AssetID, AssetName, MAX(Relationship) AS Relationship, MAX(Company) AS Company

  FROM myTable

  GROUP BY AssetID, AssetName

  Thanks Mark, but the problem is "Relationship" and "Company" columns are from different tables. Hence using two Select queries with a Union

  Where as AssetID and AssetName are from a single table. Therefore there are 3 tables involved

  Perhaps you could post the DDL for the tables. Meanwhile, this may work

  SELECT t.AssetID, t.AssetName, r.Relationship, c.Company

  FROM myTable t

  LEFT OUTER JOIN RelationshipTable r ON r.AssetID = t.AssetID

  LEFT OUTER JOIN Company c ON c.AssetID = t.AssetID

  Sorry, I may have mislead you.

  The values under Relationship is taken from 2 tables.

  Table1 -> AssetID, AssetName

  Table2 -> Relationship1

  Table3 -> Relationship2

  Table4 -> Company

  Hence for each record I am getting duplicate values since one of the Relationship is null and the other has value

  The sample query I have something like:

  Select A.AssetID, A.AssetName, B.Relate as Relationship, C.Company

  from table and joins

  union

  Select A.AssetID, A.AssetName, B.Relatedby as Relationship, C.Company

  from table and joins

  Bit of a guess here. Posting DDL with some sample data would help a lot.

  WITH CTE AS (

  Select A.AssetID, A.AssetName, B.Relate as Relationship, C.Company

  from table and joins

  union

  Select A.AssetID, A.AssetName, B.Relatedby as Relationship, C.Company

  from table and joins

  )

  SELECT AssetID, AssetName, MAX(Relationship) AS Relationship, MAX(Company) AS Company

  FROM CTE

  GROUP BY AssetID, AssetName

  If you post the whole query, we won't have to make so many guesses.

  Its a pretty big query but here it is:

  SELECT distinct

  BASE1.AssetID AS a

  ,BASE1.Name As b

  ,case when BASE2.AssetID like 'AST%' then 'Asset Records' else '' end as c

  ,replace(RELA.Name,char(10),'') As d

  ,BASE2.Name AS f

  ,BASE1.Company AS g

  LEFT JOIN BMC_CORE_BMC_BaseElement BASE2 (NOLOCK)

  ON RELA.Destination_InstanceId = BASE2.InstanceId AND Base2.DatasetId='BMC.ASSET'

  LEFT JOIN AST_CMDB_Associations AST (NOLOCK)

  ON AST.request_id02 = BASE1.ReconciliationIdentity

  and AST.Request_ID02 != '0' and AST.Request_ID01 != '0'

  and AST.form_name01 <> 'TMS:TASK' and AST.form_name01 <> 'WOI:WorkOrder'

  where 1=1

  and BASE1.AssetID = 'abcd'

  UNION ALL

  SELECT distinct

  BASE1.AssetID AS a

  ,BASE1.Name As b

  ,case

  when AST.form_name01 = 'HPD:Help Desk' then 'Incident'

  when AST.form_name01 = 'CHG:Infrastructure Change' then 'Infrastructure Change'

  when AST.form_name01 = 'PBM:Known Error' then 'Known Error'

  when AST.form_name01 = 'PBM:Problem Investigation' then 'Problem Investigation'

  when AST.form_name01 = 'RMS:Release' then 'Release'

  when AST.form_name01 = 'PBM:Solution Database' then 'Solution Database' end As c

  ,replace(CMDB_Associations.Alias_Value COLLATE DATABASE_DEFAULT,char(10),'') AS d

  ,AST.Request_id01 AS e

  ,AST.Request_Description01 AS f

  ,BASE1.Company AS g

  FROM

  BMC_CORE_BMC_BaseElement BASE1 (NOLOCK)

  LEFT JOIN BMC_CORE_BMC_BaseRelationship RELA (NOLOCK)

  ON BASE1.InstanceId = RELA.Source_InstanceId

  LEFT JOIN BMC_CORE_BMC_BaseElement BASE2 (NOLOCK)

  where 1=1

  and BASE1.AssetID = 'abcd'

  This would give something like:

  a b c d e f g

  abcd SDPQ OPDA

  abcd SDPQ Asset Record test dcba fgh OPDA

  Its a pretty big query but here it is:

  <<snip>>

  The FROM list and WHERE clause of both of the queries is identical:

  FROM BMC_CORE_BMC_BaseElement BASE1 (NOLOCK)

  LEFT JOIN BMC_CORE_BMC_BaseRelationship RELA (NOLOCK)

  ON BASE1.InstanceId = RELA.Source_InstanceId

  LEFT JOIN BMC_CORE_BMC_BaseElement BASE2 (NOLOCK)

  ON RELA.Destination_InstanceId = BASE2.InstanceId

  AND Base2.DatasetId='BMC.ASSET'

  LEFT JOIN AST_CMDB_Associations AST (NOLOCK)

  ON AST.request_id02 = BASE1.ReconciliationIdentity

  and AST.Request_ID02 != '0' and AST.Request_ID01 != '0'

  and AST.form_name01 <> 'TMS:TASK' and AST.form_name01 <> 'WOI:WorkOrder'

  WHERE BASE1.AssetID = 'abcd'

  FROM BMC_CORE_BMC_BaseElement BASE1 (NOLOCK)

  LEFT JOIN BMC_CORE_BMC_BaseRelationship RELA (NOLOCK)

  ON BASE1.InstanceId = RELA.Source_InstanceId

  LEFT JOIN BMC_CORE_BMC_BaseElement BASE2 (NOLOCK)

  ON RELA.Destination_InstanceId = BASE2.InstanceId

  AND Base2.DatasetId='BMC.ASSET'

  LEFT JOIN AST_CMDB_Associations AST (NOLOCK)

  ON AST.request_id02 = BASE1.ReconciliationIdentity

  and AST.Request_ID02 != '0' and AST.Request_ID01 != '0'

  and AST.form_name01 <> 'TMS:TASK' and AST.form_name01 <> 'WOI:WorkOrder'

  WHERE BASE1.AssetID = 'abcd'

  - and deduplication in each is performed by the DISTINCT, which operates on the output list. If you can fathom out how to more predictably deduplicate the result sets using GROUP BY, then you would get away with one query.

  These queries are identical after the FROM. Any chance you can consolidate this so you only need 1 query?

  As a side note, why all the nolock hints?

  and BASE1.AssetID = 'abcd'

  ) x

  group by A, b, g

  These queries are identical after the FROM. Any chance you can consolidate this so you only need 1 query?

  As a side note, why all the nolock hints?

  --EDIT--

  Didn't refresh before posting. It seems Chris has much the same comment as me. 😛

  Thanks guys, seems to work fine for one record:

  Are you familiar with aggregate data? Notice the query has MAX and group by. That means it is only going to get 1 row. If you need assistance with this you need to post ddl and sample data. We are totally shooting blind. Take a look at the first link in my signature for best practices when posting questions.

  I have to ask again....why the NOLOCK hints?

  I apologize for posting the wrong way, I was in a hurry and did not go through the best practices. Anyway, the issue is solved now, used a couple of sub queries, case statements and business logic, not even using the UNION now.

  And I removed the NOLOCK hints (thanks for pointing it out 🙂 ), I was just modifying an existing stored procedure.

  Thanks a lot for your time and help,
