SQL语句如何在最后增加一行合计

用UNION就行了。

select a,b,c,d from table1 union all select sum(a) as a,sum(b) as b,sum(c) as c,sum(d) as d from table1

select * from Table1

union all select name+' Toal' name ,sum(num1),sum(num2) from Table1

where name not in('Lab','R&D')

group by name

--order by name

union all select 'R&D & Lab' name,sum(num1),sum(num2) from Table1

where  name in('Lab','R&D')

union all select 'Total' name,sum(num1),sum(num2) from Table1

order by name
