I have to find out how many of our customers fall within a range of average $s.

I'm not sure how to begin.

I have a field "average" in the account master table that states each customers "average order".

I need a count of customers that fit in the following average ranges:
0-9.99
10-19.99
20 - 49.99
50 - 99.99
100 - 499.99
500 - 999.99
1000 - 4999.99
5000 and over

I hope this gives you enough information

I'm thinking:


SELECT '    0.00 to    9.99' As Range, COUNT(*) Num_Customers FROM Table WHERE AVG_AMT BETWEEN 0 AND 9.99 UNION ALL 
SELECT '   10.00 to   19.99' As Range, COUNT(*) Num_Customers FROM Table WHERE AVG_AMT BETWEEN 10 AND 19.99  UNION ALL
SELECT '   20.00 to   49.99' As Range, COUNT(*) Num_Customers FROM Table WHERE AVG_AMT BETWEEN 20 AND 49.99  UNION ALL
SELECT '   50.00 to   99.99' As Range, COUNT(*) Num_Customers FROM Table WHERE AVG_AMT BETWEEN 50 AND 99.99  UNION ALL
SELECT '  100.00 to  499.99' As Range, COUNT(*) Num_Customers FROM Table WHERE AVG_AMT BETWEEN 100 AND 499.99  UNION ALL
SELECT '  500.00 to  999.99' As Range, COUNT(*) Num_Customers FROM Table WHERE AVG_AMT BETWEEN 500 AND 999.99  UNION ALL
SELECT ' 1000.00 to 4999.99' As Range, COUNT(*) Num_Customers FROM Table WHERE AVG_AMT BETWEEN 1000 AND 4999.99 UNION ALL 
SELECT 'OVER        5000.00' As Range, COUNT(*) Num_Customers FROM Table WHERE AVG_AMT >  5000

Put the values into a table avgtamnts (lamnt, hamnt) and

select lamnt, hamnt, sum(case when AVG_AMT between lamnt and hamnt then 1 else 0 end
from tbl, avgtamnts
group by lamnt, hamnt

==========================================
Cursors are useful if you don't know sql.
DTS can be used in a similar way.
