新手问题:计算数值不在区间中的个数?
SQL code

--建表
create table #tb([rev] varchar(200),[mon] money)
go
 insert into #tb values              
('(A) $0  - $8,248 ',    0.00),
('(A) $0  - $8,248 ',    55.08),
('(A) $0  - $8,248 ',    90000.12),--不在,(A)
('(A) $0  - $8,248',     0.00),
('(A) $0  - $8,248',     0.00),
('(C) $30,455  - $91,850',     48888.728),
('(B) $8,249  - $30,419',     103079.28),--不在,(B)
('(A) $0  - $8,248 ',    0.00),
('(A) $0  - $8,248 ',    0.00),
('(D) $91,929  - $16,905,130 ',    306454.166),
('(B) $8,249  - $30,419',     13.38),--不在,(B)
('(A) $0  - $8,248',     0.00),
('(D) $91,929  - $16,905,130 ',    8989171792.96);--不在,(D)

--要求:统计[mon]的数值不在[rev]对应的区间中的个数?
/*
结果为:
[type]  [num]
 (A)      1
 (B)      2
 (C)      0
 (D)      1  
*/
