请教高手组织一条SQL语句

问题描述：
     譬如数据库一个表A中的字段a_a的值为：sum(gz.ylgz) as "应领工资",sum(gz.slgz) as "实领工资"
    现在有一条SQL语句，譬如:select xm as "姓名", ryid as "RYID" from gz where gz.id = 3
问题：如何组织成如下的SQL语句：
    select xm as "姓名", ryid as "RYID",sum(gz.ylgz) as "应领工资",sum(gz.slgz) as "实领工资" from gz where gz.id = 3 group by ryid,xm
要求：sum(gz.ylgz) as "应领工资",sum(gz.slgz) as "实领工资"  这句代码是从A表中的a_a字段随时查询而出；
