"group by" by excluding prefix

[littlebeam]

Suppose there is a table containing these recodes.

country
-------
CON_CHN
CON_JAP
JAP
CON_CHN

When I use the following sql:
select country, count(*) as num from table group by country

the normal result will be:
country num
---------------
CON_CHN 2
CON_JAP 1
JAP 1

However, my desired result is as follows:
country num
-----------------
CON_CHN 2
CON_JAP 2

How can I re-write my SQL? Or any other methods to do that?

Re: "group by" by excluding prefix

Is the length of the string (prefix or sufix) fixed? Can the string be
something like CON_CANA ? Also, it would help if you provided sample
scripts....

Re: &quot;group by&quot; by excluding prefix

If your prefix is always "CON_" then this should work

SELECT Replace(country , 'CON_',''), COUNT(Replace(c ountry, 'CON_',''))
from myTable
Group by Replace(country , 'CON_','')
