mysql分组查询每组最后一条数据_MySQL分组查询每组最新的一条数据

开发中经常会遇到，分组查询最新数据的问题，比如下面这张表(查询每个地址最新的一条记录)：

sql如下：

--------------------------------Table structure for test------------------------------

DROP TABLE IF EXISTS`test`;CREATE TABLE`test` (

`id`int(11) NOT NULLAUTO_INCREMENT,

`name`varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,

`address`varchar(10) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,

`create_time`timestamp(0) NULL DEFAULT CURRENT_TIMESTAMP,PRIMARY KEY(`id`) USING BTREE

) ENGINE= InnoDB AUTO_INCREMENT = 13 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT =Dynamic;--------------------------------Records of test------
