比方说,我想插入这样的数据:
Row 1: People = '40', Places = '15'
Row 2: People = '5', Places = '10'
我明白,这是你将怎样执行上面:
mysql_query("INSERT INTO mytable(`People`, `Places`)
VALUES ('40', '15'),('5', '10')");
但是,如果我想要的东西插入到两个以上的列使用单个查询? 如果要插入的数据是这样的:
Row 1: People = '40', Places = '15'
Row 2: People = '5', Places = '10'
Row 3: Things = '140', Ideas = '20'
Row 4: People = '10', Things = '5', Ideas = '13'
我似乎无法找到这样的其他地方的问题。
离开列你不wanto,以填补null
INSERT INTO mytable(`People`, `Places`, Things, Ideas)
VALUES ('40', '15', null, null),(null, null, 100, 20)
mysql_query("INSERT INTO mytable(`People`, `Places`, `Ideas`, `things`)
VALUES ('40', '15', null, null),
(null, '5', '10', null),
('10', null, '11', '12')");
或者,如果你想使用0,而不是空,它可能会更加对你友好的应用程序(没有抛出空错误)
mysql_query("INSERT INTO mytable(`People`, `Places`, `Ideas`, `things`)
VALUES ('40', '15', '0', '0'),
('0', '5', '10', '0'),
('10', '0', '11', '12')");
INSERT INTO mytable(`People`, `Places`,`Things`,`Ideas`)
VALUES ('40', '15', null, null),
('5', '10',null, null),
(null, null, '140','20'),
('10',null,'5','13')");
你可以写在这样一个单行单独的查询语句:
insert into table_x (collumn_x,collumn_y) values (... ;
insert into table_x (collumn_y, collumn_z) values (...
等等
该结构dinamically安装声明可能是复杂的建设,但至少是唯一的解决方案,我可以在瞬间想出了ü
希望这可以帮助你
