Hello, @likly .

#{} does not accept expression. <bind /> helps in some cases.

<select ...>
  <bind name="creatorId" value="entity.creator != null ? entity.creator.id : null" />
  select * from creator where id = #{creatorId}
</select>

Please let us know the details if it didn't work.

Please let us know the details if it didn't work. Thanks, @harawata . It's worked when use <bind/> tag. But it will be better if can use like this

 <bind name="creator" value="entity.creator != null ? entity.creator.id : null">#{creator}</bind>

I have create a Pull Request to support this.

For text substitution, you can use ${}, but it is usually not recommended. Please see the FAQ.
