GeoPackage Files with Character Fields of Width Zero or Greater than 254
When opening a GeoPackage table, MapInfo Pro searches for character fields in the table with either a width of zero (0) or that exceed 254. MapInfo Pro then sets those table columns to "read-only" in order to prevent truncation of data.
Text objects in a GeoPackage Table
MapInfo Pro replaces text objects with null (empty) geometries when saving a copy of a table to the GeoPackage (GPKG) format. If you add text objects while editing a GeoPackage table and then save the table, MapInfo Pro displays a "Text object is not supported" message.
Time Data Type Fields in GeoPackage Tables
MapInfo Pro does not support the Time data type for GeoPackage tables, because the standard global GeoPackage specification does not support this data type. For a list of supported GeoPackage data types, see www.geopackage.org/spec/#table_column_data_types.
When saving a Native MapInfo (TAB) table with Time fields to a GeoPackage table, the Time fields are automatically converted to large integer values. These values may range from zero (0) for 12:00:00 AM or 00:00:00.000 to 235959999 for 11:59:59.999 PM or 23:59:59.999. Therefore, you might prefer to convert any Time field to DateTime (or Char) prior to saving the Native table to GeoPackage.
