Sum and Total Query

[priya siva]

Hi,
I'm new to mysql. I've a table in which I've 'domain name', 'number of email addresses', and 'date'. I need to find the top 10 domains by count sorted by percentage growth of the last 30 days compared to the total. Can any one please let me know the query ?

I've tried the below query, but it seems that it is incorrect.

SELECT domain_name, SUM(num_of_mailing_addr),(SUM(num_of_mailing_addr)/SUM(SUM(num_of_mailing_addrt)) * 100 ) AS percentage_growth FROM domain_mail_count WHERE date BETWEEN (CURRENT_DATE()-30) AND CURRENT_DATE() GROUP BY domain_name ORDER BY percentage_growth DESC LIMIT 10;

Thanks in advance
