模型user,address

User中的userid和address中的user_id进行一对多

user sql

CREATE TABLE `NewTable` (
`userid`  int(11) NOT NULL AUTO_INCREMENT ,
`account`  varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL ,
`password`  varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL ,
PRIMARY KEY (`userid`)
)
ENGINE=InnoDB
DEFAULT CHARACTER SET=utf8 COLLATE=utf8_general_ci
AUTO_INCREMENT=40
ROW_FORMAT=COMPACT
;

address sql

CREATE TABLE `NewTable` (
`addressid`  int(11) NOT NULL AUTO_INCREMENT ,
`addressinfo`  varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL ,
`user_id`  int(11) NULL DEFAULT NULL ,
PRIMARY KEY (`addressid`),
FOREIGN KEY (`user_id`) REFERENCES `user` (`userid`) ON DELETE RESTRICT ON UPDATE RESTRICT,
INDEX `userud` (`user_id`) USING BTREE
)
ENGINE=InnoDB
DEFAULT CHARACTER SET=utf8 COLLATE=utf8_general_ci
AUTO_INCREMENT=77
ROW_FORMAT=COMPACT
;
