在liquibase中更新查询

Question

我需要在liquibase中运行下面的更新查询，但我不确定语法。任何人都可以请帮助：

update xyz.users 
set email = (select CONCAT(username, '@gmail.com ') "email" 
from xyz.users) 
where email like '%@yahoo.com%' ; 

Answer 1

试试这个

<update tableName="xyz.users"> 
    <column name="email" valueComputed="(select CONCAT(username, '@gmail.com ') 
from xyz.users)"/> 
<where>email like '%@yahoo.com%'</where> 
</update>
