旧的PHP函数“mysql_list_fields()”已弃用。所以，现在获取字段名称的最好方法是查询“SHOW COLUMNS FROM table_name [LIKE 'name']”。这里有一个小例子:

$fields = array();
$res=mysql_query("SHOW COLUMNS FROM mytable");
while ($x = mysql_fetch_assoc($res)){
  $fields[] = $x['Field'];
}
foreach ($fields as $f) { echo "<br>Field name: ".$f; }

function get_col_names(){  
    $sql = "SHOW COLUMNS FROM tableName";  
    $result = mysql_query($sql);     
    while($record = mysql_fetch_array($result)){  
     $fields[] = $record['0'];  
    }
    foreach ($fields as $value){  
      echo 'column name is : '.$value.'-';  
}  
 }  

return get_col_names();

我不是专家，但这对我有用。

$sql = "desc MyTable";
$result = @mysql_query($sql);
while($row = @mysql_fetch_array($result)){
    echo $row[0]."<br>"; // returns the first column of array. in this case Field

      // the below code will return a full array-> Field,Type,Null,Key,Default,Extra    
      // for ($c=0;$c<sizeof($row);$c++){echo @$row[$c]."<br>";}    

}

这将生成一个带逗号分隔符的列名字符串:

    SELECT CONCAT('(',GROUP_CONCAT(`COLUMN_NAME`),')') 
    FROM `INFORMATION_SCHEMA`.`COLUMNS` 
    WHERE `TABLE_SCHEMA`='database_name' 
    AND `TABLE_NAME`='table_name';

你可以使用以下查询MYSQL:

SHOW `columns` FROM `your-table`;

下面是示例代码，它展示了如何在php中实现上述语法来列出列的名称:

$sql = "SHOW COLUMNS FROM your-table";
$result = mysqli_query($conn,$sql);
while($row = mysqli_fetch_array($result)){
    echo $row['Field']."<br>";
}

关于SHOW COLUMNS FROM TABLE输出的详细信息请访问:MySQL参考。

我在SQL Server中尝试过这个查询，这对我有用:

SELECT name FROM sys.columns WHERE OBJECT_ID = OBJECT_ID('table_name')
