如果我们想要column_name＆amp; column_type或数据类型： 选择column_name，        COLUMN_TYPE   来自information_schema.columns  table_name ='personal_info';

如果我们只想要column_name：

选择column_name   来自information_schema.columns  table_name ='personal_info';

如果我们只想要column_type： 选择column_type   来自information_schema.columns  table_name ='personal_info';
