Question

can someone please help me with this sql query. it gives me a 1064 error suggesting I have a syntax error in my query. I’ve looked for the error over 2 hours now and getting frustrated now.

SELECT 
 SUM(IF( (`date` >= DATE_SUB(?, INTERVAL 6 MONTH)) AND (`date` < DATE_SUB(?, INTERVAL 5 MONTH)), earnings, 0)) AS Rev5,
 SUM(IF( (`date` >= DATE_SUB(?, INTERVAL 5 MONTH)) AND (`date` < DATE_SUB(?, INTERVAL 4 MONTH)), earnings, 0)) AS Rev4,
 SUM(IF( (`date` >= DATE_SUB(?, INTERVAL 4 MONTH)) AND (`date` < DATE_SUB(?, INTERVAL 3 MONTH)), earnings, 0)) AS Rev3,
 SUM(IF( (`date` >= DATE_SUB(?, INTERVAL 3 MONTH)) AND (`date` < DATE_SUB(?, INTERVAL 2 MONTH)), earnings, 0)) AS Rev2,
 SUM(IF( (`date` >= DATE_SUB(?, INTERVAL 2 MONTH)) AND (`date` < DATE_SUB(?, INTERVAL 1 MONTH)), earnings, 0)) AS Rev1,
 SUM(IF( (`date` >= DATE_SUB(?, INTERVAL 1 MONTH)) AND (`date` < ?), earnings, 0)) AS Rev0
FROM
 hat_adsense_stats
GROUP BY 
 domain
ORDER BY
 domain

thanks here is the error:

Error Code: 1064

You have parameter place holders on your query, which do not work on pure sql. The only time ? works is when you create a Dynamic SQL.

If you are working with query that is not a Dynamic SQL, you should provide a value for that.

On example to remove the syntax error on the statement is to create a user variable, eg

SET @date = CURDATE();
SELECT 
 SUM(IF( (`date` >= DATE_SUB(@date, INTERVAL 6 MONTH)) AND (`date` < DATE_SUB(@date, INTERVAL 5 MONTH)), earnings, 0)) AS Rev5,
 SUM(IF( (`date` >= DATE_SUB(@date, INTERVAL 5 MONTH)) ........
