mysql HAVING語句 語法
作用：在 SQL 中增加 HAVING 子句原因是，WHERE 關鍵字無法與合計函數(shù)一起使用。
語法：SELECT column_name, aggregate_function(column_name) FROM table_name WHERE column_name operator value GROUP BY column_name HAVING aggregate_function(column_name) BY column_name HAVING aggregate_function(column_name) operator value#。
