I've marked the changes that I made in bold. It gets you the required results : [code="sql"]Declare @sql Varchar(MAX) DECLARE @Product varchar(max)Select @sql = 'SELECT ProductID, ' +STUFF((Select DISTINCT ',MAX(Case When ParentFeatureName = ' + CHAR(39) + ParentFeatureName + CHAR(39) + ' Then ChilFeatureName Else ' + CHAR(39) + CHAR(39) + ' End) As ' + ParentFeatureName From #Test For XML PATH('')),1,1,'') + ' FROM #Test Group By ProductID' SET @Product = '[b]Select tProductId, tProductName, Type, Technology, Coated From [/b](SELECT * FROM #tProduct) AS P JOIN [b]([/b]'+@SQL+'[b])[/b] AS T ON P.tProductID = T.ProductID' Execute (@Product)[/code] If you still don't understand then print the variable @product for both the queries...yours and mine....you'll see the difference. Hope this worked out for you.Tue, 15 Jan 2013 02:21:25 GMTvinu512http://www.sqlservercentral.com/Forums/Topic1406313-392-1.aspxWhen I run the SQL you posted, I don't get that error at all. Instead I get complaints that the objects in bold (fragment of your assignment to @SQL) don't exist:[code="sql"][b]ParentFeatureName[/b] + CHAR(39) + ' Then ChilFeatureName Else ' + CHAR(39) + CHAR(39) + ' End) As ' + [b]ParentFeatureName[/b] From [b]#Test[/b] [/code]Neither the column name nor the referenced table are provided in the DDL.Then of course there's the question of "what do you think you're assigning to @Product?" It starts with an open paren. Is that supposed to be a subquery or something?Tue, 15 Jan 2013 01:44:48 GMTdwain.chttp://www.sqlservercentral.com/Forums/Topic1406313-392-1.aspx[code="sql"]CREATE TABLE #Test ( ProductID int, MainMasterFeatureID int, --MasterFeatureValue Varchar(100), ChilFeatureName varchar(100), ParentFeatureName varchar(100) )--Inserting Sample Data INSERT INTO #TestSELECT 40,1,'Pack','Type' UNION ALL SELECT 40,0,'Laminate','Technology'UNION ALLSELECT 40,11,'Yes','Coated'UNION ALLSELECT 52,1,'Roll','Type'UNION ALLSELECT 52,11,'NO','Coated'CREATE TABLE #tProduct ( tProductID int PRIMARY KEY, tProductCode nvarchar(128), tProductName nvarchar(256) )INSERT INTO #tProductSELECT 40,'001','ABC'UNION ALLSELECT 52,'002','XYZ'UNION ALLSELECT 50,'006','IJK'Declare @sql Varchar(MAX) Select @sql = 'SELECT ProductID, ' +STUFF((Select DISTINCT ',MAX(Case When ParentFeatureName = ' + CHAR(39) + ParentFeatureName + CHAR(39) + ' Then ChilFeatureName Else ' + CHAR(39) + CHAR(39) + ' End) As ' + ParentFeatureName From #Test For XML PATH('')),1,1,'') + ' FROM #Test Group By ProductID' DECLARE @Product varchar(max) SET @Product = '(SELECT * FROM #tProduct) AS P JOIN'+@SQL+' AS T ON P.tProductID = T.ProductID'[/code]this error is coming..tried a lot [code="plain"]Msg 156, Level 15, State 1, Line 2Incorrect syntax near the keyword 'AS'.[/code] Now I want to join this dynamic query to #tProduct to get the desired results: [code="plain"]tProductID tProductName Type Technology Coated 40 ABC Pack Laminate YES 52 XYZ Roll Null No [/code]Mon, 14 Jan 2013 23:33:26 GMTSQL006http://www.sqlservercentral.com/Forums/Topic1406313-392-1.aspx[quote][b]SQL006 (1/14/2013)[/b][hr]thanks vinuNow i am trying to join this query with a table to get the desire results[code="sql"] CREATE TABLE #tProduct ( tProductID bigint PRIMARY KEY, tProductCode nvarchar(128), tProductName nvarchar(256), tManufacturerName nvarchar(256), tProductDescription nvarchar(4000) )EXECUTE ('SELECT * FROM #tProduct AS P JOIN(SELECT ProductID, +STUFF((Select DISTINCT '',MAX(Case When ParentFeatureName = '' + CHAR(39) + ParentFeatureName + CHAR(39) + '' Then ChilFeatureName Else '' + CHAR(39) + CHAR(39) + '' End) As '' + ParentFeatureName From #Test For XML PATH('')),1,1,'''') + FROM #Test Group By ProductID'' ) AS A ON P.tProductID = A.ProductID') [/code]I am getting this error[code="plain"]Msg 156, Level 15, State 1, Line 4Incorrect syntax near the keyword 'AS'.[/code][/quote]First suggestion I have is build the dynamic query into a variable. Second, PRINT it out so you can see the query itself to be sure it is what you expect. If you print it, you can copy it to another query window to test that it actually runs. This is what I do when writing a dynamic query as it is sometimes hard to be sure you have the correct number of single quotes in the correct places otherwise.Mon, 14 Jan 2013 06:56:43 GMTLynn Pettishttp://www.sqlservercentral.com/Forums/Topic1406313-392-1.aspxthanks vinuNow i am trying to join this query with a table to get the desire results[code="sql"] CREATE TABLE #tProduct ( tProductID bigint PRIMARY KEY, tProductCode nvarchar(128), tProductName nvarchar(256), tManufacturerName nvarchar(256), tProductDescription nvarchar(4000) )EXECUTE ('SELECT * FROM #tProduct AS P JOIN(SELECT ProductID, +STUFF((Select DISTINCT '',MAX(Case When ParentFeatureName = '' + CHAR(39) + ParentFeatureName + CHAR(39) + '' Then ChilFeatureName Else '' + CHAR(39) + CHAR(39) + '' End) As '' + ParentFeatureName From #Test For XML PATH('')),1,1,'''') + FROM #Test Group By ProductID'' ) AS A ON P.tProductID = A.ProductID') [/code]I am getting this error[code="plain"]Msg 156, Level 15, State 1, Line 4Incorrect syntax near the keyword 'AS'.[/code]Mon, 14 Jan 2013 05:53:48 GMTSQL006http://www.sqlservercentral.com/Forums/Topic1406313-392-1.aspxI think this is what you are looking for...it would dynamically flatten your data : [code="sql"]--Creating Table CREATE TABLE #Test ( ProductID int, MainMasterFeatureID int, --MasterFeatureValue Varchar(100), ChilFeatureName varchar(100), ParentFeatureName varchar(100) )--Inserting Sample Data INSERT INTO #TestSELECT 40,1,'Pack','Type' UNION ALL SELECT 40,0,'Laminate','Technology'UNION ALLSELECT 40,11,'Yes','Coated'UNION ALLSELECT 52,1,'Roll','Type'UNION ALLSELECT 52,11,'NO','Coated'--Dynamic Cross Tab QueryDeclare @sql Varchar(MAX) Select @sql = 'SELECT ProductID, ' Select @sql = @sql + STUFF((Select DISTINCT ',MAX(Case When ParentFeatureName = ' + CHAR(39) + ParentFeatureName + CHAR(39) + ' Then ChilFeatureName Else ' + CHAR(39) + CHAR(39) + ' End) As ' + ParentFeatureName From #Test For XML PATH('')),1,1,'') Select @sql = @sql + ' FROM #Test Group By ProductID' Execute(@sql) [/code] Hope this helps.Sun, 13 Jan 2013 23:04:38 GMTvinu512http://www.sqlservercentral.com/Forums/Topic1406313-392-1.aspxThen I suggest reading the following:[b][url]http://www.sqlservercentral.com/articles/T-SQL/63681/[/url][/b][b][url]http://www.sqlservercentral.com/articles/Crosstab/65048/[/url][/b]Sat, 12 Jan 2013 03:31:52 GMTLynn Pettishttp://www.sqlservercentral.com/Forums/Topic1406313-392-1.aspxHi Lynn, thanks for the replyThe value in ParentFeatureName can be dynamically change..it will not always give the same valueI am trying this dynamic pivot..but still not getting the desire results there is error[code="sql"][strike]DECLARE @ParentFeatureName varchar(max)SELECT @ParentFeatureName = STUFF((select distinct ',['+'ParentFeatureName'+']' from #Test for xml path(' ')),1,1,'')--error is coming here to get the distict value [/strike]SELECT @ParentFeatureName = (SELECT SUBSTRING( (SELECT DISTINCT ',' + CAST(ParentFeatureName as Varchar(MAX)) FROM #Test FOR XML PATH('')),2,2000000)) [strike]SELECT ProductID,'+@ParentFeatureName+'FROM(SELECT * FROM #Test) AS DPIVOT( MIN(MasterFeatureValue) FOR ParentFeatureName IN ('+@ParentFeatureName+') ) AS DDGroup By ProductID[/strike]DECLARE @sql VARCHAR(max)SET @sql = 'SELECT ProductID,'+@ParentFeatureName+'FROM(SELECT * FROM #Test) AS DPIVOT( MIN(MasterFeatureValue) FOR ParentFeatureName IN ('+@ParentFeatureName+') ) AS DDGroup By ProductID'EXEC @sql[/code]Sat, 12 Jan 2013 02:28:16 GMTSQL006http://www.sqlservercentral.com/Forums/Topic1406313-392-1.aspxThis is what I developed:[code="sql"]CREATE TABLE #Test ( ProductID int, MainMasterFeatureID int, MasterFeatureValue Varchar(100), ChilFeatureName varchar(100), ParentFeatureName varchar(100) );
