Question

(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?

Answer 1

Use the group by clause:

SELECT Date, COUNT(uid) FROM users group by Date;
