HQL语法问题

Question

我遇到以下HQL查询的问题：

select sum(MYTABLE.COUNTER) from (

select count(DISTINCT bi.products.id)  as COUNTER 
                   from BusinessInformation as bi 
                   where bi.informationOwners.id in (100) 
                   and bi.products.id in (10) 
                   and bi.valueAmount not in ('NA')
                   and ((bi.valueType = 'ACHIEVED' and bi.referenceYears.id = 1) or (bi.valueType = 'FINAL_BALANCE' and bi.referenceYears.id = 2)) 
                   group by bi.informationOwners.id                   
)  MYTABLE

编译器报告：

org.hibernate.hql.ast.QuerySyntaxException: unexpected token: ( near line 1, column 34

你知道查询有什么问题吗？我测试了内部查询，它工作正常。

谢谢， ç

HQL subqueries can occur only in the select or where clauses，而非FROM。
