[英]Add new field to multiple table at once?
I want to add same field to multiple tables. 我想将相同的字段添加到多个表。 Can I do this with single query in MySql? 我可以在MySql中使用单个查询执行此操作吗?
I don't think you can do this with a single query, as it requires the ALTER TABLE
syntax which only supports one table per query (although you could add/modify multiple columns in the same table). 我不认为你可以用一个查询来做这件事,因为它需要ALTER TABLE
语法,每个查询只支持一个表(尽管你可以在同一个表中添加/修改多个列)。
You have to do one ALTER TABLE
query per table to be modified. 您必须对每个表执行一次ALTER TABLE
查询以进行修改。
