如何在mybatis动态sql中使用where子句中的函数？

问题描述

这是我的选择代码

QueryExpressionDSL<SelectModel>.QueryExpressionWhereBuilder sql =
                SelectDSL.select(CreativeDailyDtoDynamicsqlSupport.mallId)
                .from(CreativeDailyDtoDynamicsqlSupport.creativeDailyDto)
                .where()
                .and(Add.of(CreativeDailyDtoDynamicsqlSupport.click,CreativeDailyDtoDynamicsqlSupport.impr),IsIn.of(1L,2L,3L));

在这个查询中，我想创建类似的 sql

select mall_id from creative_daily_table where (click+impr) in (1,2,3)

但它抛出异常

### The error may exist in com/pdd/service/koduck/repository/mapper/CreativeDailyDtoMapper.java (best guess)
### The error may involve com.pdd.service.koduck.repository.mapper.CreativeDailyDtoMapper.selectMany-Inline
### The error occurred while setting parameters

mybatis 动态 sql 中似乎不支持 where cluase 的函数。

有什么解决方法吗？
