need a SQL query

Hi,

I am using Oracle 10g, I have the following requirement:

I want fetch the count of all position patterns with in a number pool.

For e.g if there is a database table with SNO and status as the DB columns, the data representation is as follows:

SNO, STATUS
-------------------
1, Y
2 , Y
-- , --
100, Y

assuming that the table has records from 1 to 100.

I want to write an optimized SQL query which will list out the count of numbers starting with 1,2,3 .... 100

Start with, Count
-------------------
1 , 12 (there are 12 numbers between 1 to 100 which start with 1)
2 , 11
-- , --
10 , 2


Thanks and Regards
Jay

select sno, count(*)
from your_table
group by sno ;

Select substr(sno,1,1) starts_with, count(*)
from <table>
group by substr(sno,1,1)


--Did'nt run the query...you got the concept...fix if you have syntax error..

Cheers,

SIR,
i have two tables
one is q_bank and another is blueprint
in q_bank i have col subject question and category(A,B,C)
in blueprint i have the no for A,B,C(01,01,02)
now i need a query so that output should be question and category but no of rows are decided by values of A,B,C from blueprint table

q_bank table for example -
question subject cat
define x x A
define y y B
define z x A
define 1 y A
define2 x B
define n x C
define t y C

blueprint
subject A B C
X 1 0 1
y 2 1 0

my requirement that query should give question from q_bank and no of question should be limited by numbers of A,B,C of blueprint

thanx
