I want to to combine 2 databases of business listings (table rows) into one database. All the listings (rows) are unique but the problem is that some of them have same database ids. So when try to import the second database, it gives me an error:
1062 - Duplicate entry '1' for key 'PRIMARY' .
How can I solve that problem? Maybe to make an SQL query to remove the ids of the second database so the rows will get new ids when imported.
Sorry if my question looks stupid, but I'm not a coder :)
