MySQL 5.7.9版本sql_mode=only_full_group_by問題
用到GROUP BY 語句查詢時com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘col_user_6.a.START_TIME‘ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by錯誤
解決方法 (修改全局):執行set global sql_mode = ‘‘; 把sql_mode 改成非only_full_group_by模式。驗證是否生效 SELECT @@GLOBAL.sql_mode 或 SELECT @@sql_mode
執行(只是修改會話級別的,只是當前會話生效)set session sql_mode = ‘‘; 把sql_mode 改成非only_full_group_by模式。驗證是否生效 SELECT @@GLOBAL.sql_mode 或 SELECT @@sql_mode
