Hi,
I want to select multiple columns into one single table column in sql server like,

| COLUMN 1 | COLUMN 2 | COLUMN 3 |          COLUMN 4             |
------------------------------------------------------------------
|      |          |          | SUB COL1 | SUB COL2 | SUB COL3|
|      |          |      |      |          |     |
|      |          |      |      |          |     |
|      |          |      |      |          |     |
|      |          |      |      |          |     |
|      |          |      |      |          |     |

In this figure Column 4 contains three sub columns. Is there any way to get the table result like this?

One simple way is like this :
Select T1.C1,t1.C2,T1.C3,T2.C1 +' | '+T2.C2+' | ' + T2.C3 as 'Col1 | Col2 | Col3'
from table1 T1
Left Outer Join
Table2 T2 ON T1.id=t2.id

provide more details about your requirement and your table details

This is something related to how UI looks like. This should be handled at UI, not at back end.

Do you require same display at DB level?

Solution 3

You can't divide a column into sub columns. As Rohan has said in the comments this should be addressed at the UI layer.

You should return result as
Column1 | Column2 | Column3 | Sub Column 1 | Sub Column 2 | Sub Column 3

and in the DataGrid you should apply a Template to show Sub Column 1 ... Sub Column 3 as Column 4
