CREATE TABLE `news` (
`ID` int(10) unsigned NOT NULL auto_increment,
`username` char(8) NOT NULL ,
`daytime` datetime DEFAULT '0000-00-00 00:00:00',
`title` char(20) NOT NULL,
`content` varchar(250) NOT NULL default '',
`group` int(1) NOT NULL DEFAULT '0',
PRIMARY KEY (`ID`)
);
要用group作为查询条件：……where group=?;？号处该这样用呢？
我尝试了：select * from news where group=0;
和select * from news where group='0';
