For more information, see WITH common_table_expression (Transact-SQL). For information about table hints, see Table Hints (Transact-SQL).TOP ( ) Specifies one or more table hints that are allowed for a target table. @ When referencing the Unicode character data types nchar, nvarchar, and ntext, 'expression' should be prefixed with the capital letter ' N'.If you are planning on converting that data back into a string, you'll need some code to do so.Here's a function I wrote that does this: CREATE FUNCTION Convert Binary ( @value AS varbinary(max) ) RETURNS VARCHAR(MAX) AS BEGIN DECLARE @result AS varbinary(max), @result2 AS varchar(max), @idx AS bigint; IF @value IS null return null; SELECT @result = @value; SELECT @result2 = ''; SELECT @idx = 1; WHILE substring(@result, @idx, 1) !If ' N' is not specified, SQL Server converts the string to the code page that corresponds to the default collation of the database or column.Any characters not found in this code page are lost.= 0 AND @idx I don't know how helpful this will be for you, though, since it's very possible that whatever app is using these fields is handling the values differently than this function expects. For the record, this function takes a varbinary value which was originally utf-8 string, and returns the varchar value of that string.

So say Question ID is NULL and Answer ID is 500, if we go to the Answers table and find Answer ID 500 there is a column with the Question ID that should have been where the NULL value is.

In this case, since a missing question ID would change the NULL to NULL, it arguably doesn't matter.
