我已经创建 .sql 文件有这样的代码:
ALTER TABLE `tb_1` ADD `ex1` TINYINT( 1 ) NOT NULL DEFAULT '0'
ALTER TABLE `tb_2` ADD `ex2` tinyint(1) NOT NULL DEFAULT '1'
ALTER TABLE `tb_3` ADD `ex2` varchar(35) NOT NULL
ALTER TABLE `tb_1` ADD `ex1` TINYINT( 1 ) NOT NULL DEFAULT '0';
ALTER TABLE `tb_2` ADD `ex2` tinyint(1) NOT NULL DEFAULT '1';
ALTER TABLE `tb_3` ADD `ex2` varchar(35) NOT NULL;
