Solution 1

Use this:

SQL

if exists(select 1 from table1 a inner join table2 b on b.S_no=a.sl_no)
delete a from table1 a inner join table2 b on b.S_no=a.sl_no
else
select * from table2

Solution 2

Running a loop[^] on these tables along with the IF-ELSE statement[^] will help you achieve a solution.
