I have two table
table 1
file number
110
111
123

table 2
file number
124
125
167
111

first I want to check in table 1 the largest value then add 1 to that value.
after that I want to check the newvalue in table 1 exist in table2 if yes again add 1 to it and re-compare(repeat this process untill we unique value)

What should happen if there are no matches between the two tables? What do you mean by “repeat this process untill we unique value”?
