语句直接在命令行运行就能查出接过来,在phpMyAdmin里面也能查到,但是写到程序里就出错,请大神帮忙看看。
代码是这个
$sql =" select * from $table_list where $length_left qq $length_right $textif $t;"; $mysqli = new mysqli("localhost","root","root",'qq_db');$mysqli->set_charset("utf8");if ($mysqli->connect_errno){ die("Connect Error :".$mysqli->connect_error); }$result = $mysqli->query($sql);var_dump($result);$mysqli->close();sql语句实际输出的结果是select * from qq_list where length( qq = 5) and qq like '%1%' and wuzheng;
运行后就提示bool(false)
