Currently only SSMS v17 release candidates support updating cells encrypted using Always Encrypted.Tables that use sparse columns can designate a column set to return all sparse columns in the table.A column set is an untyped XML representation that combines all the sparse columns of a table into a structured output.Column sets can be visualized as a minitable and a select operation is like a SELECT * operation on this minitable.But, the relationship between column set to sparse columns is a grouping relationship instead of strictly a container.

It returns an XML column with the combined values of the sparse columns.

You will be given questions that you need to solve.

After each exercise, we provide the solution so you can check your answer.

The following table lists the data types and the default values that the server generates when the value is not provided. Generates an error when a value is specified for this attribute by the caller in the XML representation provided for a column set in an insert or update operation.

The security model for a column set works similar to the security model that exists between table and columns.
