Help with HOUR() query

Hello,

I have a quick question.

In mySQL you can do the following, where messages.date is a datetime column:

Code:

SELECT HOUR( date ) AS time FROM messages;

I would like to select all columns from messages, where HOUR( date ) = 1 for example. How do I do this? Also, how would I issue a count?

ex in english:

"Select the column count AS total FROM messages WHERE HOUR( messages.date ) is 1"

Thanks in advance for your help.

what do you mean by "issue a count"? you mean a count of the number of rows that have the hour equal to 1? that would give you a one-row answer, and you can't get that at the same time as the columns
