db_productsテーブル：

| ID | Name         |
| 40 | Foo Bar!~~~~ |

スラッグ名列を生成したい:

| ID | Name         | Slug_Name |
| 40 | Foo Bar!~~~~ | foo-bar   |

これは実際にSQL経由で実行できますか? または、別の言語を使用してスクリプトを作成する必要がありますか?

編集:私はこの関数を使用してPHPでスラッグを生成しています:

function toSlug($string,$space="-") {
    if (function_exists('iconv')) {
        $string = @iconv('UTF-8', 'ASCII//TRANSLIT', $string);
    }
    $string = preg_replace("/[^a-zA-Z0-9 -]/", "", $string);
    $string = strtolower($string);
    $string = str_replace(" ", $space, $string);
    return $string;
}

これまでのところ、私の SQL スキルはかなり基本的なものです。

ALTER TABLE db_products ADD Slug_Name VARCHAR

Slug_Name = toSlug(Name)SQLで各行とセットをループするにはどうすればよいですか?

単一のクエリを使用した簡単なソリューションを次に示します。

UPDATE `my_table` SET alias = lower(name),
alias = replace(alias, '.', ' '),
alias = replace(alias, '\'', '-'),
alias = replace(alias,'š','s'),
alias = replace(alias,'Ð','Dj'),
alias = replace(alias,'ž','z'),
alias = replace(alias,'Þ','B'),
alias = replace(alias,'ß','Ss'),
alias = replace(alias,'à','a'),
alias = replace(alias,'á','a'),
alias = replace(alias,'â','a'),
alias = replace(alias,'ã','a'),
alias = replace(alias,'ä','a'),
alias = replace(alias,'å','a'),
alias = replace(alias,'æ','a'),
alias = replace(alias,'ç','c'),
alias = replace(alias,'è','e'),
alias = replace(alias,'é','e'),
alias = replace(alias,'ê','e'),
alias = replace(alias,'ë','e'),
alias = replace(alias,'ì','i'),
alias = replace(alias,'í','i'),
alias = replace(alias,'î','i'),
alias = replace(alias,'ï','i'),
alias = replace(alias,'ð','o'),
alias = replace(alias,'ñ','n'),
alias = replace(alias,'ò','o'),
alias = replace(alias,'ó','o'),
alias = replace(alias,'ô','o'),
alias = replace(alias,'õ','o'),
alias = replace(alias,'ö','o'),
alias = replace(alias,'ø','o'),
alias = replace(alias,'ù','u'),
alias = replace(alias,'ú','u'),
alias = replace(alias,'û','u'),
alias = replace(alias,'ý','y'),
alias = replace(alias,'ý','y'),
alias = replace(alias,'þ','b'),
alias = replace(alias,'ÿ','y'),
alias = replace(alias,'ƒ','f'),
alias = replace(alias, 'œ', 'oe'),
alias = replace(alias, '€', 'euro'),
alias = replace(alias, '$', 'dollars'),
alias = replace(alias, '£', ''),
alias = trim(alias),
alias = replace(alias, ' ', '-'),
alias = replace(alias, '--', '-') ;

この例では:

  • 「my_table」はテーブルの名前です。
  • 「名前」は元のフィールドです
  • 「エイリアス」は私のスラッグフィールドの名前です

それが役に立てば幸い ！

MySQL を使用して文字列置換を実行できます。公式ドキュメントには、役に立つと思われるかなりの数の文字列関数がリストされています。

SELECT REPLACE('Foo Bar!~~~~', '~', '');
SELECT LOWER('Foo Bar!');

また、MySQL での正規表現の使用に関するこのブログ投稿にも出くわしました。

更新：私が言及したブログ投稿の詳細：

したがって、正規表現の置換を行う関数を作成することをお勧めします。

DELIMITER $$
FUNCTION `regex_replace`(pattern varchar(1000),replacement varchar(1000),original varchar(1000))
RETURNS varchar(1000)
DETERMINISTIC
BEGIN
DECLARE temp VARCHAR(1000);
DECLARE ch VARCHAR(1);
DECLARE i INT;
SET i = 1;
SET temp = original;
IF original REGEXP pattern THEN
    SET temp = "";
    loop_label: LOOP
    IF i>CHAR_LENGTH(original) THEN
        LEAVE loop_label;
    END IF;
    SET ch = SUBSTRING(original,i,1);
    IF NOT ch REGEXP pattern THEN
        SET temp = CONCAT(temp,ch);
    ELSE
        SET temp = CONCAT(temp,replacement);
    END IF;
    SET i=i+1;
END LOOP;
END IF;
RETURN temp;
END$$
DELIMITER ;

次に、次のようなもの

SELECT regex_replace('[^a-zA-Z0-9]+', '', '%$&?/’|test><+-,][)(' )

そのアプローチに慣れていない場合は、replace を使用して更新呼び出しをいつでも実行できます。

update db_products set Slug_Name = replace(Name, '~', '');
