In the datawarehouse DB (under MS commerce server 2002) a table stores
the referer domain name. Table structure is like
refererdomainid <binary>,domainInternalFlag
<0/1>,refererDomainName<varchar
e.g.
<binary>|0|unknown
<binary>|1|google.com
<binary>|1|yahoo.com
<binary>|1|google.com
<binary>|1|google.com
<binary>|1|google.com
<binary>|1|altavista.com
my problem is to build a query (using this table only) which
refererDomainName has the max occurrence and how many times. As in the
table above it is google.com and 4 times.
Can anyone help me.
Thanks in advance.Here are two alternatives:
SELECT refererdomainname, COUNT(*)
FROM SomeTable
GROUP BY refererdomainname
HAVING COUNT(*) >= ALL
(SELECT COUNT(*)
FROM SomeTable
GROUP BY refererdomainname)
SELECT TOP 1 WITH TIES
refererdomainname, COUNT(*)
FROM SomeTable
GROUP BY refererdomainname
ORDER BY COUNT(*) DESC
