这个怎么样:

SELECT @cCommand := GROUP_CONCAT( COLUMN_NAME ORDER BY column_name SEPARATOR ',\n')
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE TABLE_SCHEMA = 'my_database' AND TABLE_NAME = 'my_table';

SET @cCommand = CONCAT( 'SELECT ', @cCommand, ' from my_database.my_table;');
PREPARE xCommand from @cCommand;
EXECUTE xCommand;

如果你喜欢的话，还有这个:

mysql_query('SHOW COLUMNS FROM tableName'); 

$col = $db->query("SHOW COLUMNS FROM category");

while ($fildss = $col->fetch_array())
{             
    $filds[] = '"{'.$fildss['Field'].'}"';
    $values[] = '$rows->'.$fildss['Field'].'';
}

if($type == 'value')
{
    return $values = implode(',', $values);
}
else {
     return $filds = implode(',', $filds);
}

我需要列名作为平面数组，而其他答案返回关联数组，所以我使用:

$con = mysqli_connect('localhost',$db_user,$db_pw,$db_name);
$table = 'people';

/**
* Get the column names for a mysql table
**/

function get_column_names($con, $table) {
  $sql = 'DESCRIBE '.$table;
  $result = mysqli_query($con, $sql);

  $rows = array();
  while($row = mysqli_fetch_assoc($result)) {
    $rows[] = $row['Field'];
  }

  return $rows;
}

$col_names = function get_column_names($con, $table);

$col_names现在等于:

(
    [0] => name
    [1] => parent
    [2] => number
    [3] => chart_id
    [4] => type
    [5] => id
)

下面的SQL语句几乎是等价的:

SELECT COLUMN_NAME
  FROM INFORMATION_SCHEMA.COLUMNS
 WHERE table_name = 'tbl_name'
  [AND table_schema = 'db_name']
  [AND column_name LIKE 'wild']

SHOW COLUMNS
FROM tbl_name
[FROM db_name]
[LIKE 'wild']

参考:INFORMATION_SCHEMA列

这对我很有效。

$sql = "desc MyTableName";
$result = @mysql_query($sql);
while($row = @mysql_fetch_array($result)){
    echo $row[0]."<br>";
}
