string mysql_error ([resource $link_identifier])

The PHP function mysql_error() will return the error message generated by the previous MySQL function, or an empty string if there is no error.

The sample code for using the mysql_error() function is as follows:

<ol class="dp-xml"><li class="alt"><span><span class="tag"><</span><span> ?php  </span></span></li><li><span>$</span><span class="attribute">connection</span><span>=</span><span class="attribute-value">mysql_connect<br /></span><span>("localhost","root","root") <br />or die("连接服务器失败");  </span></li><li class="alt"><span>mysql_select_db("mydb",$connection);  </span></li><li><span>echo "错误信息:".mysql_error();  </span></li><li class="alt"><span class="tag">?></span><span> </span></span></li></ol>
