HQL查询中类型转换的问题

org.hibernate.QueryException: insertion type [org.hibernate.type.BigDecimalType@1d48c] and selection type [org.hibernate.type.DoubleType@293354] at position 2 are not compatible [insert into WsqSqbProfitReportEntity(openId,sqbType,**balanceProfit**,consumeProfit,profitDate,status) select u.openId,'01'**,round(u.userBalance*2.1/36000,2)**,round(u.userConsume*7.5/36000,2),sysdate,'1' from com.lefu.entity.sqb.WsqUserSqbInfoEntity u where u.endDate >= sysdate and u.sqbType = '01']

问题相当于向表WsqSqbProfitReportEntity中插入数据，其balanceProfit的类型为BigDecimal，但是,round(u.userBalance*2.1/36000,2)计算出的结果为double类型，导致插入出错，请问应该如何解决呢
谢谢大神指导

解决方案

用cast实现类型转换：
cast((round(u.userBalance*2.1/36000,2)) as BigDecimal)

解决方案二：

最后使用createSqlQuery的方式解决
