This is not a good question to be asking. Especially if you are working with SQL.
You need tables to have fewer fields, not more. The more fields there are the slower your system will be. Work on optimizing your database design so that you never come to a point where you need to know how many you can add.
If you reach the error message limit, then you really have too many fields and need to rethink your system design.

yes , it is not based on the fields
