Hi Folks,

Having some wierd problems with indexing in my query. If I run the

select basket.*, companies.Company_ID as Company_ID
from basket
inner join companies on basket.Company_ID=companies.Company_ID

An index is used for companies.Company_ID and basket.Status. The
minute I try to pull anything else through from the companies table
select basket.*, companies.Company_ID as Company_ID, companies.Name)
It won't use the Company_ID index, even though the inner join is using
it. Why is that?

Any help or direction to investigate would be great.

Many thanks

This has nothing to do with php.
