Answer / mala yadav

select command is used to fetch the result from the table ,
but of u want the combine results from more than 1 table
then in this case we use JOINS rather than a single table
select statement.

In joins u can join upto 2 to 61 tables to get tha required
result.

joins are of 5 types
- inner join
- self join
- cross join
