Datasources and Queries

MapInfo Pro supports some datasource types that Spectrum Spatial does not. An upload cannot be performed if TAB files point to data stored in one of these formats:

In any of the above cases, you can either cancel the upload or continue without the unsupported layer. If you require this layer in your named map, however, you will need to convert the table to a Native TAB or any other supported datasource (see Using Data from Unsupported Datasources).

Supported datasources include:

Query Layers

MapInfo Pro allows users to create layers based on the results of a SQL select or any selection in MapInfo Pro. These are layers for which the data is not in a physical table but is instead the result of a query.

Also, MapInfo Pro allows users to create a layer based on a query of a single table; for example, select * from CustomerPoints where SALES >= 100000. This is a query table, not a physical entity but derived from a physical entity. This named view is what is referenced by the named layer.

You can either cancel or continue without the unsupported layer. Otherwise, to use this layer in your named map you must save the query as a native TAB or any other supported datasource (see Using Data from Unsupported Datasources).
