Using the new SQL server provider with geometry table, it's not possible to have the attribut datas in the window 'attribut table' of QGIS.
We got only "ERROR" on every row.
It's not possible to select on feature on the map, if we click on one all features are selected.
We try several SQL server table and got always the same problem.

The problem comes from a column in uniqueIdentifier. The only format for the key seems to be integer.

Feature id in QGIS can only be 64 bit in size. The SQL uniqueidentifier type (which is 16 bytes) not sufficient for this purpose. Use int or bigint data types for the feature id column.
