MySQL SELECTとURLデコード

PHP実行するのではなく、MySQLクエリを実行して出力の列の1つを直接urldecodeする方法がありますか？.

たとえば、この「連絡先」テーブルには、

------------------------------------ 
 | name | email | 
 ------------------------------------ 
 |ジョンスミス| johnsmith％40hotmail。 com | 
 ------------------------------------
SELECT * FROM `contacts`

出力します、

ジョン・スミス| johnsmith%[email protected]

それに沿って何かありますか

SELECT name, urldecode(email) FROM `contacts`

出力するには、

ジョン・スミス| [email protected]

PHPコードの別の行を使用して、JQueryオートコンプリートに使用されるjson_encodeに渡される前に、SQLステートメントからクエリ応答をurldecodeすることに成功しました。

元の質問に回答することが重要であるように感じます（選択肢に関係なく）。主に質問され、有効な質問だからです。

短い答え：できません。

URLエンコードされた文字列をデコードするためのネイティブSQL関数はありません。

長い答え：カスタムSQL関数を記述する必要があります。

MySQL関数のエンコード/デコード： http://www.dzone.com/snippets/urlencodeurldecode-mysql

ベストアンサー：エンコードされたURLはすべてUTF8として保存できます。

ダンプし、「latin1」を「utf8」に置き換え、インポートして、テーブルをUTF8に変更します。次に、PHP、Python、またはRails）などのスクリプトを（一度だけ）実行して列をデコードし、それを保存します。これで、DBを意図したとおりに使用する準備ができました。いいえオーバーヘッド。

これを行うPythonコード：

import urllib

import MySQLdb

def decode():

  con = MySQLdb.Connect(Host="127.0.0.1", port=3306, user="root", passwd="", db="hostip")
  cursor = con.cursor()

  cursor.execute("SELECT city, name FROM cityByCountry")

  for row in cursor.fetchall():
    print row
    cursor.execute("UPDATE cityByCountry SET name=%s WHERE city=%s", (urllib.unquote(row[1]), row[0]))

if __name__ == "__main__":
  decode()

私の解決策は、URLエンコードされた文字列をデコードするストアド関数を宣言することです。

DELIMITER $$

DROP FUNCTION IF EXISTS URL_DECODE $$

CREATE FUNCTION URL_DECODE (str text) 
RETURNS text
DETERMINISTIC
BEGIN 
    DECLARE result text;
    DECLARE ind INT DEFAULT 0;

    SET result = REPLACE(str, '+', ' ');

    WHILE ind <= 255 DO
       SET result = REPLACE(result, CONCAT('%', LPAD(LOWER(HEX(ind)), 2, 0)), CHAR(ind));
       SET result = REPLACE(result, CONCAT('%', LPAD(HEX(ind), 2, 0)), CHAR(ind));
       SET ind = ind + 1;
    END WHILE;

    RETURN result;
END$$

DELIMITER ;

そして次の方法で使用するより：

SELECT URL_DECODE('johnsmith%40hotmail.com')

Roman

エンコードされたURLの特殊文字$ & + , / : ; = ? @（空白は含まれません）を含む可能性のあるデータレコードを選択し、そのようにする（サンプルコード）ときの解決策が必要でした。

SELECT * FROM `table` WHERE `field` REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(`field`,'%24','$'),'%26','&'),'%2B','+'),'%2C',','),'%2F','/'),'%3A',':'),'%3B',';'),'%3D','='),'%3F','?'),'%40','@') LIKE '/example-request-uri?'

私の答えはMistdemonに非常に似ていますが、次の変更点があります。

（1）この行が一番上の挿入物である必要があります：

INSERT INTO urlcodemap（encoded、decoded）VALUES（ "％25"、 "％"）;

それ以外の場合、スペースは％の前にあるため、スペースは％20ではなく％2520として出力されます...

（2）ポストのURLエンコーディングの場合、A-Z、a-z、および0-9のすべての行を削除します。ポストサーバーは間違いなく標準的な文字と数字を読むことができます...そして、全体はゴブリンゴックのようには見えません。
