Can I use the result of a SUM function in the WHERE clause of SQL?

Question

For example suppose I have

SELECT sum(...) as total

Can I do something like

WHERE total > 10

When I try that actual syntax I get an error unknown column 'total' in 'where clause' using MySQL

Answer 1

对于涉及聚集的条件，请使用HAVING而不是WHERE ：

SELECT SUM(somecolumn) AS total FROM sometable HAVING total > 10;

Answer 2

尝试HAVING

HAVING total > 10
