SELECT * FROM my_table WHERE (foo = 'bar') OR (foo = 'bar_bar') OR (foo = 'bar_bar_bar')";有没有办法找出$result的每一行是否与foo = 'bar'、foo = 'bar_bar'或foo = 'bar_bar_bar'匹配while($row = mysql
我已经将C:\Program Files\MySQL\MySQL Server 5.6\my-default.ini复制到C:\Program Files\MySQL\MySQL Server 5.6\当我登录到数据库并查看table_definition_cache值时,会得到以下信息:
mysql> SHOW GLOBAL VARIABLES LIKE '%table_definition_cache
