如何獲得sqlite 3中給定表的所有列名的列表？ （表可能是空的）

Question

現在我使用：

PRAGMA table_info(table_name) 

結構，但它不允許我以縮小搜索結果的列名，因爲它原來很多不需要的數據。這是數組的數組

Array 
(
    [0] => Array 
     (
      [cid] => 0 
      [name] => id 
      [type] => INTEGER 
      [notnull] => 0 
      [dflt_value] => 
      [pk] => 1 
     ) 

    [1] => Array 
     (
      [cid] => 1 
      [name] => name 
      [type] => TEXT 
      [notnull] => 0 
      [dflt_value] => 
      [pk] => 0 
     ) 

    [2] => Array 
     (
      [cid] => 2 
      [name] => timestamp 
      [type] => INTEGER 
      [notnull] => 0 
      [dflt_value] => 
      [pk] => 0 
     ) 

    [3] => Array 
     (
      [cid] => 3 
      [name] => note 
      [type] => TEXT 
      [notnull] => 0 
      [dflt_value] => 
      [pk] => 0 
     ) 

) 

這將是結果不如做個

Array 
(
    [0] => id 
    [1] => title 
    [2] => timestamp 
    [3] => note 
) 

但選擇PRAGMA table_info name（表名）不工作

你不能改變table_info的輸出，但是重複循環結果對象並構建所需的列名稱數組很簡單。
