LOB Columns & sys.partitions

On the table and index organization page in the sql server documentation link here, under the Allocation Units section, the documentation states:

Each table that has at least one LOB column also has a row in sys.partitions with index_id > 250.

Whilst looking for sparsely populated image columns in one of my tables that’s taking up waay too much room I noticed that said table does indeed contain a LOB column (image data type), yet has no index listed in sys.partitions with an index_id > 250.


Here is the results from querying the sys.partitions table:


Here’s the allocations from the sys.system_internals_allocation_units table.  Obviously a bunch of unused space in this table.


Is the documentation wrong?  Why you sys.partitions no have index_id > 250 for image column?

Y U No - sys.partitions why u no idx gt 250?
