有T1和T2两张表
T1：fcompanyno,fitemno,fitemname
cqan 1300001 扳手5'寸
cqan 1300002 扳手6'寸
cqan 1300003 扳手7'寸
tjan 1300001 扳手5'寸
tjan 1300002 扳手6'寸
dlan 1300001 扳手5'寸
T2: id,fcompanyno,fitemno,fitemname，fqty,fprice,famount
1, cqan 1300001 扳手5'寸 50 13.5 675
2, cqan 1300005 扳手9'寸 40 12 480
3, tjan 1300002 扳手6'寸 30 12 360
4, tjan 1300006 扳手7'寸 60 15 900
需要查找fcompanyno,fitemno在T2中存在记录，但是在fcompanyno,fitemno中没有的数据
求SQL语句，要求查询结果为：
cqan 1300005 扳手9'寸
tjan 1300006 扳手7'寸
------解决方案--------------------
create table T1(fcompanyno varchar(10),fitemno varchar(10),fitemname varchar(10))
insert into T1
select 'cqan',1300001,'扳手5''寸'
union all select 'cqan',1300002,'扳手6''寸'

create table T2(id int,fcompanyno varchar(10),fitemno varchar(10),fitemname varchar(10),
fqty int ,fprice numeric(12,2),famount numeric(12,2))
insert into T2
