我有一个MySQL问题,我认为这很容易。当我运行以下MySql查询时,我需要从table1返回LAST INSERTED ID:
INSERT INTO table1 (title,userid) VALUES ('test',1); INSERT INTO table2 (parentid,otherid,userid) VALUES (LAST_INSERT_ID(),4,1); SELECT LAST_INSERT_ID();
如您所知,当前代码只会返回table2的LAST INSERT ID而不是table1,即使我插入到table2之间,也如何从table1获取ID?
您可以将最后一个插入ID存储在变量中:
INSERT INTO table1 (title,userid) VALUES ('test', 1); SET @last_id_in_table1 = LAST_INSERT_ID(); INSERT INTO table2 (parentid,otherid,userid) VALUES (@last_id_in_table1, 4, 1);
或获取max id frm table1
INSERT INTO table1 (title,userid) VALUES ('test', 1); INSERT INTO table2 (parentid,otherid,userid) VALUES (LAST_INSERT_ID(), 4, 1); SELECT MAX(id) FROM table1;
