Passing a TABLE variable into dynamic SQL

A question popped up on StackOverflow today, asking how to pass a TABLE variable into a dynamic SQL statement in SQL Server 2008. I've previously blogged about table-valued parameters, comparing the approach of passing in a TABLE of values to a stored procedure to the techniques you'd have had to use in earlier versions of SQL Server (e.g. CSV or XML), but this specific question is worth a quick follow-up.

Passing a TABLE variable in to a dynamic SQL statement is straight forwards:

-- First define a custom TABLE type
CREATE TYPE IntegerTableType AS TABLE (ID INTEGER)
GO

-- Fill a var of that type with some test data
DECLARE @MyTable IntegerTableType
INSERT @MyTable VALUES (1),(2),(3)

-- Now this is how you pass that var into dynamic statement
EXECUTE sp_executesql N'SELECT * FROM @MyTable', 
    N'@MyTable IntegerTableType READONLY', 
    @MyTable

Job done.
