mysql_error()函数如果执行的话,每次都显示千篇一律的内容吗
mysql_error()可用在mysql_connect()和mysql_query()执行失败时,那是否不同的情况下,mysql_error()会有不同的文字输出呢?

------解决方案--------------------
$conn=mysql_connect($DBHost,$DBUser,$DBPassword) or die( "数据库连接失败 " . mysql_error());
mysql_select_db($DBDatabase,$conn) or die( "Could not select database ");
$result=mysql_query($sql,$conn) or die( "Query failed : " . mysql_error());

后面的or die可以改成自己的提示信息

------解决方案--------------------
不同的错误显示不同的内容
