将Mysql数据导出到Excel下载时如何下载特定字段？
如果我想在excel下载的时候更改字段名称提交用户，该怎么做？ 如何在所选表格中下载特定列？
<?php /*******EDIT LINES 3-8*******/ $DB_Server = "localhost"; //MySQL Server $DB_Username = "username"; //MySQL Username $DB_Password = "password"; //MySQL Password $DB_DBName = "databasename"; //MySQL Database Name $DB_TBLName = "tablename"; //MySQL Table Name $filename = "excelfilename"; //File Name /*******YOU DO NOT NEED TO EDIT ANYTHING BELOW THIS LINE*******/ //create MySQL connection $sql = "Select * from $DB_TBLName"; $Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect to MySQL:<br>" . mysql_error() . "<br>" . mysql_errno()); //select database $Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database:<br>" . mysql_error(). "<br>" . mysql_errno()); //execute query $result = @mysql_query($sql,$Connect) or die("Couldn't execute query:<br>" . mysql_error(). "<br>" . mysql_errno()); $file_ending = "xls"; //header info for browser header("Content-Type: application/xls"); header("Content-Disposition: attachment; filename=$filename.xls"); header("Pragma: no-cache"); header("Expires: 0"); /*******Start of Formatting for Excel*******/ //define separator (defines columns in excel & tabs in word) $sep = "\t"; //tabbed character //start of printing column names as names of MySQL fields for ($i = 0; $i < mysql_num_fields($result); $i++) { echo mysql_field_name($result,$i) . "\t"; } print("\n"); //end of printing column names //start while loop to get data while($row = mysql_fetch_row($result)) { $schema_insert = ""; for($j=0; $j<mysql_num_fields($result);$j++) { if(!isset($row[$j])) $schema_insert .= "NULL".$sep; elseif ($row[$j] != "") $schema_insert .= "$row[$j]".$sep; else $schema_insert .= "".$sep; } $schema_insert = str_replace($sep."$", "", $schema_insert); $schema_insert = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert); $schema_insert .= "\t"; print(trim($schema_insert)); print "\n"; } ?> 我正在使用上面提到的代码将Mysql数据导出到Excel下载。 为ex，在我的表中，我有ID，名称，状态，create_date的字段。
但@出口MySQL数据的时候，Excel的下载我只想把名字和地位的字段。 帮助我解决这个问题。 感谢
提前。
你可能只是在寻找一个只select你想要的列的查询，就像这样：
$sql = "Select name as organization, status from $DB_TBLName";
而不是以下select所有列：
$sql = "Select * from $DB_TBLName";
请注意，我使用别名将name列的name更改为organization 。
