You use a Microsoft SQL Server database that contains a table named BlogEntry that has the following columns:

Id is the Primary Key.

You need to append the -This is in a draft stage- string to the Summary column of the recent 10 entries based on the values in EntryDateTime.

Which Transact-SQL statement should you use?

A. UPDATE TOP(10) BlogEntry

SET Summary.WRITE(N This is in a draft stage, NULL, 0)

B. UPDATE BlogEntry

SET Summary = CAST(N This is in a draft stage as nvarchar(max))

WHERE Id IN(SELECT TOP(10) Id FROM BlogEntry

ORDER BY EntryDateTime DESC)

C. UPDATE BlogEntry

SET Summary.WRITE(N This is in a draft stage, NULL, 0) FROM (

SELECT TOP(10) Id FROM BlogEntry ORDER BY EntryDateTime DESC) AS s

WHERE BlogEntry.Id = s.ID

D. UPDATE BlogEntry

SET Summary.WRITE(N This is in a draft stage, 0, 0)

WHERE Id IN(SELECT TOP(10) Id FROM BlogEntry

ORDER BY EntryDateTime DESC)

Explanation:

The UPDATE SET colum_name.WRITE (expression,@Offset,@Length) command specifies that a section of the value of column_name is to be modified. expression replaces @Length units starting from @Offset of column_name.

If @Offset is NULL, the update operation appends expression at the end of the existing column_name value and @Length is ignored.
