I have 3 tables T1, T2,T3 with values as shown below.

T1	 	 	 	T2	 	 	T3	 	 
A	B	C	 	X	Y	 	J	K	L
A11	B11	C11	 	A11	Y11	 	J11	K11	Y11
A12	B11	C12	 	A11	Y12	 	J12	K12	Y12
A13	B12	C13	 	A11	Y11	 	J13	K13	Y13
A14	B12	C14	 	A12	Y12	 	J14	K14	Y14
A15	B12	C15	 	A13	Y11	 	J15	K15	Y15

Query 1:
Select b from (Select count(*) b from T1, T2 where T1.A = T2.X and T2.Y = ?) where b>0;
where ‘?’ => a value from table T3 in column L

Suppose if I replace ‘?’ with Y11 the output of the query is as follows
B
----
3
 
Query 2:
Select T3.J, T3.K, T3.L from T3 where T3.K='K11'

Output
J	K	L
-------------------
J11	K11	L11
 
I need the output in the following format using a single query

T3.J	T3.K	T3.L	b
--------------------------
J11	K11	L11	3

ie., all the fields in the table t3(second query) and the count obtained in the first query. For this purpose the query 1 and query2 needs to be combined…

All the above relations hold good
Ie., T2.X contains values present in T1.A
T3.L contains values present in T2.Y

PS: the problem is that in query 1, the value replacing ‘?’ is a value from T3. I will not be able to join T3 and T1 with any matching criteria as there is no common fields in these two tables. 
Also simply I can’t join T3 in the first query since it will result in the wrong number of count being fetched
The second query will always return only one row
