Importing Profiles and ID numbers.

I am going to be importing a large profile table into a database with only four members.  How is the counter for IDs generated?  Is that stored in the database for the join to know the next ID number to apply?  I will need to adjust the counter after the import so that IDs are assigned correctly, correct?

Hello

ID field in Profiles table uses MySQL Autoincrement. So, if you import a list of profiles then the Autoincrement continue to work from the biggest ID which was added into DB during import. So, you shouldn't have any problems.
