用字符'更新mysql'

Question

在我的价值中，我有角色＆＃39;我收到一个错误。

我该如何解决？

    UPDATE products
SET description = CASE
    WHEN id <= 350 THEN 'Sample description with ' character'
    ELSE 'sample description 2'
END

Answer 1

在SQL中转义字符的常用方法是\ so

    UPDATE products
SET description = CASE
    WHEN id <= 350 THEN 'Sample description with \' character'
    ELSE 'sample description 2'

如果你想知道如何把\放在那里，你只需加倍，即\\

Answer 2

报价加倍：

UPDATE products
SET description = CASE
WHEN id <= 350 THEN 'Sample description with '' character'
ELSE 'sample description 2'
END

Answer 3

phpMyAdmin 将报价加倍。你可以这样做：

UPDATE `products`
SET `description` = CASE
    WHEN `id` <= 350 THEN 'Sample description with '' character'
    ELSE 'sample description 2'
END
