How to use SQL to query this complex structure? Please help!?

I have this table T1, it has 3 columns:
The first column is Integer, the 2nd & the 3rd is string. These are some sample data in table T1:

1 S1 A
1 B C
2 S2 A
2 B C
3 s3 C
3 B A
4 s4 K
4 K T
4 T Y
5 S5 A
5 B C
6 S6 A
6 K L
7 S7 T
7 B C

Suppose I wanna query all the groups that has this format:
? A
B C

--> so if the query executes correctly, it will show these result
1 S1 A
1 B C
2 S2 A
2 B C
5 S5 A
5 B C

The query should not show 6 or 7 as 6 or 7 only 1 row matching.

Note: the result must go with the whole group.

Can anyone show me how to form SQL to query this?
Thax u

Suppose i have this query

select * from northwind where name like 'A%'

this would show results which are like:

APRIL

APPLE

ASADSAD

AND

(all that starts with A)

now for your question, I SUPPOSE that all your data has @@[]A
where @ = any digit or letter, followed by [] which indicates open space and A which is an end statement, you could use

select * from northwind where name like '%A'

it would show

A1 A
b2 A
c3 A

and so forth,

or you would use,

select * from northwind where name like 'S% A'

this would produce

S1 A
S2 A
S3 A
S4 A

I HOPE THIS HELPED
