Question

I have two simple tables let’s say country and state. Suppose, I need to use left join on the state table. It can be written in MySql using ANSI syntax something like the one shown below.

select c.country_id, c.country_name, s.state_name 
from country c left join state s on s.country_id=c.country_id

In Oracle, the same SQL can be rewritten using Theta syntax as follows.

select c.country_id, c.country_name, s.state_name 
from country c, state s where s.country_id(+)=c.country_id

Can I write some way the preceding SQL (Theta syntax) in MySql?, since I had been often using Theta style of SQL in Oracle.

Answer 1

You can’t use that (old Oracle) syntax in MySQL.

See this answer for why you should not be using that (old) syntax any more, not even in Oracle.
