SQL在执行查询时更新同一表上的所有错误输入条目

Question

一些帮助小伙伴，我的表名为具有以下字段的产品

[Products]
pid
name
category

问题是该类别下有很多错误的条目引用了同一类别。

错误类别示例：

Bags and wallet
Bags and Wallets
Bag and Walles
Bags & Wallets

正确一个人应该是袋子＆amp;钱包

我想使用带有子查询的单个SQL语句来更改所有内容

UPDATE products
SET category = 'BAGS & WALLETS'
FROM products 
WHERE category = (select category from products WHERE category like 'BAGS AND WALL')

Answer 1

您可以实施MySQL的REGEXP搜索：

UPDATE products
SET category = 'BAGS & WALLETS'
FROM products 
WHERE category REGEXP 'BAGS? AND WALL'

Answer 2

了解LIKE子句如何使用通配符%：

UPDATE products
SET category = 'BAGS & WALLETS'
WHERE UPPER(category) LIKE 'BAGS AND WALL%'
