| This is something I always wanted to be supported by mybatis. I even created own PR with slightly different approach, but there was no response: #1825 |
| Yeah, sorry about the lack of response. It's not fun to reject PRs. This feature, as you can imagine, is very popular and has been requested numerous times. |
| We just want to shorten the gap with hibernate and reduce the cumbersome code of development. We expect this feature to be added in the next major release. | | jxc | | ***@***.*** | On 12/17/2021 04:32，Iwao ***@***.***> wrote： Yeah, sorry about the lack of response.

The team's decision, however, was that there is already <foreach /> which does the same thing and more even though it is verbose. So, we probably won't support any simple syntax in version 3.x, at least. — Reply to this email directly, view it on GitHub, or unsubscribe.

In Hibernate, "IN" query only needs to write " in (:xxx) ". And MyBatis needs to use cumbersome script. We made the following changes to make MyBatis support the syntax of "in (#{xxx})" . For example, "select * from user where dept_id in (#{ids})" .After testing on our project, it has no negative impact on existing expressions.
