求教一个SQL语句

[biyesheji12]

我现在已经查出了所有人在11年的平均工资，但是我还想直接得出这些人平均工资的总额，请教SQL如何写，已实现的SQL语句如下：
select SUM(发合计)/COUNT(distinct SUBSTRING(年月,1,6)) as sums from 工资 where 客户ID='7295' and 年月 like '2011%' group by 雇员ID

目前结果如下：
sums
7389.165
5064.1725
6815.554166
3208.5925
5839.130833
3868.989166
5775.6575
3846.0625
6305.195833
3346.6775
369.26
......

 with A AS(
	 select SUM(发合计)/COUNT(distinct SUBSTRING(年月,1,6)) as sums 
	 from 工资 where 客户ID='7295' 
	 and 年月 like '2011%' group by 雇员ID
 )
 SELECT SUMS, SUM(SUMS)OVER() TOTAL
 FROM A
