加上like 模糊查询条件 无法输出 ,在线等!!加分
 
$conn = mysql_connect("localhost","root","");
if (!$conn){
  die("连接数据库失败:" . mysql_error());
} else {
  echo "连接数据库成功!";
}
mysql_query("set character set utf8");

$yes=mysql_select_db("ORG7188", $conn);
if (!$yes){
  die("连接数据库失败:");
} else {
  echo "连接数据库成功!";
}
$sql="SELECT * FROM 188_line where ts like '%三峡%' "; // 如果没有where语句 就可以输出内容
$socre=mysql_query($sql,$conn);

while($row = mysql_fetch_array($socre)){
  echo $row[ts];

}

?>

数据库如下  



------解决方案--------------------

select * from table where filds like binary \'%中文%\'
------解决方案--------------------
php代码是什么编码?代码、数据库、浏览器统一为utf-8。
------解决方案--------------------
这样看一下
....

$sql="SELECT * FROM 188_line where ts like '%三峡%' "; // 如果没有where语句 就可以输出内容
die(base64_encode($sql)); //加上这句,贴出结果

$socre=mysql_query($sql,$conn);

------解决方案--------------------
在MySQL中,进行中文排序和查找的时候,对汉字的排序和查找结果是错误的。
这种情况在MySQL的很多版本中都存在。如果这个问题不解决,那么MySQL将无法实际处理中文。

出现这个问题的原因是:MySQL在查询字符串时是大小写不敏感的,在编绎MySQL时一般以ISO-8859字符集作为默认的字符集,因此在比较过程中中文编码字符大小写转换造成了这种现象。

方法一:
解决方法是对于包含中文的字段加上\"binary\"属性,使之作为二进制比较,例如将\"name char(10)\";改成\"name char(10)binary\"。
方法二: 如果你使用源码编译MySQL,可以编译MySQL时使用--with--charset=gbk 参数,这样MySQL就会直接支持中文查找和排序了
