Question

select * 
from webOrders
where lastModifiedDate in (select max (lastModifiedDate) from webOrders) 

Is there a simpler way without nesting the selects?

Doing something like this also results in an error:

select id, amount, quantity, max(lastModifiedDate) from webOrders.

Answer 1

There are a couple of approaches, depending on your needs.

If you only need one row returned, you can sort on the column of interest and return the top row. For example:

select top 1 * 
from `order`
order by last_modified_date desc

if you use SQL Server or

select * 
from `order`
order by last_modified_date desc
limit 1

if you use MySQL.

If you need to get one row per group, then you do typically have to use a subquery or a join.
