I have 1 record(1row*2columns) from 1 select
and
a different select which can result in multiple rows but will always have 3 columns.
How can I repeat the 1 row next to the result set from the second select.
No common columns from these 2 selects...

Your final resultset cannot contain a mixture of numbers of columns and datatypes. But you can create a wider dataset, eg

SELECT Col1, Col2, Col3, Col4 = NULL, Col5 = NULL
from qry1
UNION ALL
SELECT Col1 = NULL, Col2 = NULL, Col3 = NULL, Col4, Col5
from qry2

My first select :

A E:\1.mdf D

A_1 E:\2_1.ndf D

A_log F:\3.ldf L

My second select:

SrvA Db1

This is what the result looked like from the query posted. Thank you for this...but

A E:\1.mdf D NULL NULL

A_1 E:\2_1.ndf D NULL NULL

A_log F:\3.ldf L NULL NULL

NULL NULL NULL SrvA Db1

...This is what I need

A E:\1.mdf D SrvA Db1

A_1 E:\2_1.ndf D SrvA Db1

A_log F:\3.ldf L SrvA Db1

this is why you should supply consumable data and desired output.

so on above example, how do we link between tbl1 and tbl2? this is assuming that there are more than 1 rows on tbl2

Like this?

WITH qry1
AS (SELECT *
    FROM
    (
        VALUES
            ('SrvA', 'Db1')
    ) x(Col4, Col5) )
    ,qry2
AS (SELECT *
    FROM
    (
        VALUES
            ('A', 'E:\1.mdf', 'D')
           ,('A_1', 'E:\2_1.ndf', 'D')
           ,('A_log', 'F:\3.ldf  ', 'L')
    ) y(Col1, Col2, Col3) )
SELECT qry2.Col1
      ,qry2.Col2
      ,qry2.Col3
      ,qry1.Col4
      ,qry1.Col5
FROM qry2
    CROSS JOIN qry1;

Dude... readily consumable data and desired result output, please! I see you finally provided some but you shouldn't need to be reminded with every post. And, no... I'm not trying to be mean... I'm trying to tell you how to help yourself.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
