Hi,

Did you try executing your sql statement -
select price, discount,(select name as 'name' from product where MKid=1) from market??

Because as per my understanding it gives all the rows in the market table for mkid 1,2,3 with a column having name - Electronic.
Is this what you want?

Try this:

SQL

SELECT price, discount, name FROM market 
LEFT JOIN product ON market.MKid = product.MKid

Hi,

As per my understanding , if you are looking for a output like,

SQL

price discount name
100     2       electronics
150     0       sports
100     0       foods

Best way is to join the 2 tables.
Hope this helps.

use left outer join instead of inner join
