mysql-query

(Sorry for the title, I don't really know how to phrase that :-) )

I have a table that has a date and a uid fields.

I need to get the number of uid for each date, currently I'm doing it in php running multiple queries like this one:

SELECT COUNT(uid) FROM users where Date = 'xxx';

Is there a simple way to achieve this with only an sql query?
