MySQL Query to Count Unique Domains from Email Address field

Question

I\'d like to get a better idea of what domains my customers are using. I could easily do this in PHP by explodeing each address and counting the domain that way

Answer 1

You can use this query to get Unique count of domain from table.

SELECT substr(email,INSTR(email,"@")+1),count(substr(email,INSTR(email,"@"))) from YOUR_TABLE group by substr(email,INSTR(email,"@"));
