Hi,
I have a table with 3 relevant columns:
symbol varchar(10) not null
price decimal not null
and
last_update datetime not null
I want to select the list of unique symbols and the corresponding price and
last_update fields for each line where the last_update is equal to the
last_update field
Octavian,
I want to select the list of unique symbols and the corresponding price and
last_update fields for each line where the last_update is equal to the
last_update field for each symbol.
You're close! See the example at
