About Supported DBMS Data Types
This section provides a list of supported data types and any data restrictions for SQL Server, PostGIS,
and Oracle.
SQL Server Data Support
Read-Only Support for Spatial Objects in SQL Server with Z and M Values
Spatial data that is stored in SQL Server Spatial Geometry and Geography field types may have Z and
M values. MapInfo Professional cannot edit this type of spatial data and ignores the Z and M values, so
you must view these tables as read-only in MapInfo Professional. If you edit this type of spatial data in
MapInfo Professional, saving the table back to the original SQL Server Spatial table does not preserve
the original Z and M values.
The MapInfo_MapCatalog has the following spatial types for tables with Z and M values:
20 - Geometry read-only support of objects with Z/M values.
21 - Geography read-only support of objects with Z/M values
