  3. Perform inserting records into the table in the database. However, you have to be sure what you are doing and that you are doing it right.
  4. Use this qiock data import.

When importing there are following rules and limitatations:

  • Only data insert is performed without taking care of existing records in the class.
  • Rules before record save are started.
  • Restrictions on column are checked - min., max. length/value, mandatory column...
  • All column types can be imported except for:
    • files
    • classes
    • multiple references to classes/users

This import is available in the administration tool. This means that is available for administrator.
