    <p>My suggestion when you are working with dynamic SQL is to always write the query hard-coded first, so you can get the logic correct, then convert it to dynamic SQL.</p> <p>Since you are attempting to pivot 3 columns of data I would first unpivot the <code>type_ds</code>, <code>expdt</code> and comdt` columns, then apply the PIVOT function.</p> <p>The hard-coded version of the query will be:</p> <pre><code>SELECT * FROM ( select pro_id, type_ds = case when col ='type_ds' then type_ds else type_ds+col end, value from ( SELECT A.Pro_Id, c.Type_DS, convert(varchar(10), b.ExpDt, 120) ExpDt, convert(varchar(10), b.ComDt, 120) ComDt FROM dbo.Project A left join [dbo].[Prj_App] B on A.Pro_id = B.Pro_Id right outer join dbo.Approval_Type C on B.App_Id = C.App_ID ) s cross apply ( select 'type_ds', type_ds union all select 'expdt', expdt union all select 'comdt', comdt ) c (col, value) ) data PIVOT ( MAX(value) FOR Type_DS IN (RMC2, RMC2expdt, RMC2comdt, RMC1, RMC1expdt, RMC1comdt) ) pvt1 </code></pre> <p>See <a href="http://sqlfiddle.com/#!3/08155/19" rel="nofollow">SQL Fiddle with Demo</a>. Now that you have a working version of the query, you can easily convert it to dynamic SQL:</p> <pre><code>DECLARE @SQL1 NVARCHAR(MAX) = '' DECLARE @SQL NVARCHAR(MAX) = '' SELECT @SQL1 = STUFF((SELECT ',' + QUOTENAME(Type_Ds) + ',' + QUOTENAME(Type_Ds + 'ExpDt') + ',' + QUOTENAME(Type_Ds + 'ComDt') from dbo.Approval_Type FOR XML PATH(''), TYPE ).value('.', 'NVARCHAR(MAX)') ,1,1,'') SET @SQL = 'SELECT * FROM ( select pro_id, type_ds = case when col =''type_ds'' then type_ds else type_ds+col end, value from ( SELECT A.Pro_Id, c.Type_DS, convert(varchar(10), b.ExpDt, 120) ExpDt, convert(varchar(10), b.ComDt, 120) ComDt FROM dbo.Project A left join [dbo].[Prj_App] B on A.Pro_id = B.Pro_Id right outer join dbo.Approval_Type C on B.App_Id = C.App_ID ) s cross apply ( select ''type_ds'', type_ds union all select ''expdt'', expdt union all select ''comdt'', comdt ) c (col, value) ) data PIVOT ( MAX(value) FOR Type_DS IN (' + @SQL1 + ') ) pvt1 ' --print @SQL EXECUTE SP_EXECUTESQL @SQL </code></pre> <p>See <a href="http://sqlfiddle.com/#!3/08155/20" rel="nofollow">SQL Fiddle with Demo</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
