Is there any problem in changing the data type from varchar to int in mysql? I have a spreadsheet with some items that have been entered as varchar, all are numbers. The problem is that I need to do a bigger and smaller search, however, as it is in varchar I do not know if it works. Also, I'm afraid to change the type and have data loss.
