A 4D object field is a persistent database field type, stored as binary content. Previously, reading this type of field by an ODBC driver wasn’t possible. Until today.
Before, an error was returned when trying to read an object field. This prevented the completion of simple Select * from myTable requests, which could be frustrating for users who only wanted to browse the content of a table.
Good news! The SQL engine has been updated to allow 4D object fields to be read.
