Please help me in this scenario.

table 1

id|name|age|status
1 |red |10 | m
2 |ben |30 | s
3 |app |90 | s
4 |low |10 | s
5 |son |50 | g

table 2

id|master|status
10|chuka | s
20|pogi  | b
30|bell  | t

If I will create a new table/query it looks like this?

SQL

DECLARE @power INT
SET @power = 40;
SELECT @power AS Level5, name, status, age 
FROM table1 inner join table2 on table2.status = table1.status
WHERE table1.status = 's'

The output is looks like this
table 3

Level5|name|status|age
40|ben | s    |30
40|app | s    |90
40|low | s    |10

My problem is, I want to make the column Level5 will increment by 10 for every row

Expected OUTPUT I want to display

Level5|name|status|age
50|ben | s    |30
60|app | s    |90
70|low | s    |10

Please Help me! Thank you!

You can do this with a help of recursive CTE[^]

SQL

;WITH CTE AS(
  SELECT @power AS Level5, 1 AS rn
  UNION ALL
  SELECT Level5 + 10, rn + 1 FROM cte WHERE rn < 100
  )
SELECT CTE.Level5, t.name, t.status, t.age FROM
(SELECT name, table2.status, age,
ROW_NUMBER() OVER (ORDER BY table1.id) AS rn
FROM table1 inner join table2 on table2.status = table1.status
WHERE table2.status = 's') AS t
INNER JOIN CTE ON t.rn=cte.rn
