Hi Suhas,
Create table TestProbables (MyNumber I, TableI I)
for i=1 to N && where N is the number of tables
     append from ("table"+transform(m.i))
     replace TableID with m.i for empty(TableID)
next

select count(TableID) as Occurrences, MyNumber from TestProbables ;
           group by MyNumber having  Occurrences >= MAXNUMBER into cursor PossibleCandidates

** There could be a case with the same number in one table, what do we want to do in such case?
If it's not broken, fix it until it is.
