So we have to take cc no as varchar, not big int.

[@LearnatKnowstar]

This is what we assumed in this example.
There might be few steps needed to get the CC data in the form we need - like trimming out the spaces or the hyphens, validating that it contains only numbers and has a minimum length of 9 etc.
