Your Query:

SELECT a.col1+'~'+       
       STUFF((
        SELECT '~' + s2.col2
        FROM tab1 s1
        RIGHT OUTER JOIN tab2 s2 ON s1.tab1_id=s2.tab2_id
        WHERE a.col1 = s1.col1
        FOR XML PATH('')
      ), 1, 1, '')  AS columns2
FROM tab1 a
RIGHT OUTER JOIN tab2 b ON a.tab1_id=b.tab2_id
WHERE a.tab1_id=105
GROUP BY a.col1

Example Query:

SELECT
s.col1+'~'+
STUFF((
        SELECT '~' + col2
        FROM Table1 s2
        WHERE s2.col1 = s.col1
        FOR XML PATH('')
      ), 1, 1, '')  AS columns2
FROM Table1 s
GROUP BY s.col1

Result:

|    COLUMNS2 |
