Examples
Sample code invoking the querySome function

The simple Querysome example

Here,we've example to check whether the 75 is exists or not in myquery mark column value.

<cfscript>
myQuery = queryNew("id,name,mark","integer,varchar,integer",[[1,"Rahu",75],[2,"Ravi",80]]);
 result = querySome(myQuery , function(details){
	 return details.mark IS 75;
 });
 writeOutput((result ? "Some" : "No") & " matches  Record found!");
</cfscript>

Expected Result: Some matches Record found!

The Query Member Function example

Here,we've example to check whether the 85 is exists or not in myquery mark column value using query member function.

<cfscript>
myQuery = queryNew("id,name,mark","integer,varchar,integer",[[1,"Rahu",75],[2,"Ravi",80]]);
 result = myQuery.Some(function(details){
	 return details.mark IS 85;
 });
 writeOutput((result ? "Some" : "No") & " matches  Record found!");
</cfscript>

Expected Result: No matches Record found!
