I need to do the search for the domain name. So user may store in the database
http://test.com or test.com or www.test.com I need to find the domain.

So if the site domain is not equals to whatever they entered in the database set varible.

I have  a piece of code that partially work . if they enter the the name without http it is working ,otherwise does not.

I need to allow the user to do it regardlesss
accessOK = 1;
if (ListFindNoCase(#cgi.server_name#,#db.homeDomain#) == 0) {
                              AccessOK = 0;
                        }

I'd start with using list functions to extract the address after the http:// (if any)

ie    
<cfset dbDomain = getToken(db.homeDomain, 2, "//")>

If you're not validating the user entry, you'll need to scrub the data further. For example if you needed to remove the www:

<cfset dbDomain = listRest(dbDomain, ".")>

But there are some gotchas with using cgi.server_name. For example, the user could enter an IP instead of a name or this one

In other words, scrub the db entry and extract the domain. Then compare it to the server name. But all bets are off if the cgi.server_name is an ip address or has been tampered with.

<!--- extract part after http:// etc... --->
<cfset dbDomain = getToken(db.homeDomain, 2, "//")>
<!--- ignore leading "www." --->
<cfset dbDomain = listRest(dbDomain, ".")>

<!--- compare values. may need to scrub further --->
<cfscript>
accessOK = 1;
if (cgi.server_name eq dbDomain ) == 0) {
     AccessOK = 0;
}
</cfscript>

oops. typo correction, this line:

    if (cgi.server_name eq dbDomain) == 0) {

should just be:

    if (cgi.server_name eq dbDomain) {
0
