Interesting!
Also, you don't need to drop the entire table, you can drop sparse columns and re-add them with the ALTER TABLE command

CREATE TABLE UserConfig ( UserConfigKey INT IDENTITY(1,1) NOT NULL CONSTRAINT UserConfigPK PRIMARY KEY , UserID INT )

ALTER TABLE UserConfig ADD Options XML COLUMN_SET FOR ALL_SPARSE_COLUMNS , IsActive BIT SPARSE , IsSubscriber BIT SPARSE , DefaultQuantity INT SPARSE

Sorry, I may be missing something but I was rather confused by this question because the question just reads "how do I add a column to this table" however the answers referred to XML data specifically.

Interesting topic though, learnt something new about SPARES data types.

That's true, though in either case, saving the data becomes a chore. I didn't think of just adding the sparse columns back and the column set, but that's cool

add a column set. That's a type of column, which is XML.

Did I misread it, or has it been amended? 🙂

misread. There are a series on column sets that are running across weeks.
