我有一个mysql表,其描述如下:
Create Table
CREATE TABLE `question` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`category` varchar(255) DEFAULT NULL,
`is_deleted` bit(1) NOT NULL,
`question` varchar(255) DEFAULT NULL,
`version` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=15 DEFAULT CHARSET=utf8
我有另一张桌子
Create Table
CREATE TABLE `parent_question` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`is_deleted` bit(1) NOT NULL,
`version` int(11) DEFAULT NULL,
`pid` bigint(20) NOT NULL,
`qid` bigint(20) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `FK8FEA83DBE860AF9` (`pid`),
KEY `FK8FEA83DBF34C20F6` (`qid`),
CONSTRAINT `FK8FEA83DBE860AF9` FOREIGN KEY (`pid`) REFERENCES `parent` (`id`),
CONSTRAINT `FK8FEA83DBF34C20F6` FOREIGN KEY (`qid`) REFERENCES `question` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=23 DEFAULT CHARSET=utf8
我有权在问题表中插入一行。所以当我添加新行时,将生成id
(因为它是auto_increment)并且我想将此id存储在{{1 field qid
table。
有人可以告诉我该怎么做吗?
答案 0 :(得分:0)
使用last_insert_id()
功能:
insert into question values (...);
insert into parent_question values (..., last_insert_id(), ...);
