好的，说得很清楚， 我的表看起来像这样：
ID post_title post_type
------------------------------------------------------
1 product A product
2 product A - Size S product_variation
3 product A - Size M product_variation
4 product A - Size L product_variation
5 product B product
6 product A - Size S product_variation
7 product A - Size M product_variation
8 product A - Size L product_variation
9 product C product
10 product A - Size S product_variation
11 product A - Size M product_variation
12 product A - Size L product_variation
13 product D product
14 product A - Size S product_variation
15 product A - Size M product_variation
16 product A - Size L product_variation
我想要像这样：
ID post_title post_type
------------------------------------------------------
1 product A product
2 product A - Size S product_variation
3 product A - Size M product_variation
4 product A - Size L product_variation
5 product B product
6 product B - Size S product_variation
7 product B - Size M product_variation
8 product B - Size L product_variation
9 product C product
10 product C - Size S product_variation
11 product C - Size M product_variation
12 product C - Size L product_variation
13 product D product
14 product D - Size S product_variation
15 product D - Size M product_variation
16 product D - Size L product_variation
如何将post_type“product”的值更改为“product_variation”的值post_title作为父级。
如果我有大约1000个产品，我该怎么改变它？？
答案 0 :(得分：0)
你可以使用替换功能
update tableName set post_title=REPLACE(post_title,'A','B') where ID in(6,7,8)
