The DBMS table can be read-only under any of the following circumstances:
- The data downloaded from the server database is not editable.
- There are no editable columns in the data downloaded from the server database.
- The data downloaded from the server database does not contain a primary index.
If the data downloaded from the server database does not contain a primary index, you can create one. Then the table will become editable. The next section explains how to create a primary index on a remote table from MapInfo Pro.
