Question

I have a table that inserts a row when a certain function is used on the site and stamps the date.

code-/----date----/--type
-----/------------/------
--1--/--2012-2-1--/-used
--1--/--2012-2-3--/-saved
--1--/--2012-1-3--/-printed
--2--/--2012-2-1--/-used
--2--/--2012-2-2--/-printed

I have to report the number of times code 1 was (printed or saved or used) today, or yesterday, or last month (date range)

I am starting with this:

$stat_query = mysql_query("SELECT code, type, date FROM tracking WHERE code IN ('$htL','$htG','$htR') GROUP BY code, type, date");

I use the IN operand because each user has 3 codes to track with limitless date entries for each type.

I really am lost as to what to do here.

Answer 1

You’ll need to construct the date ranges and modify the query. Below is an example of showing the count for code in the past day:

SELECT `code`, COUNT(`code`) as code_cnt 
FROM tracking 
WHERE 
    `code` IN ('$htL','$htG','$htR') AND
    `date` BETWEEN DATE_SUB(now(), INTERVAL 1 HOUR) AND now()
GROUP BY `code`
