sql server programming : Using temporary table in in dynamic SQL

Temporary table is different from temporary variable.
As Vishal said, we can not use temporary tables in dynamic SQL if the table
variable is defined outside of the dynamic SQL scope.

Try this:

DECLARE @sql nvarchar(800)
DECLARE @mytable nvarchar(50)
SET @mytable = 'dbo.author'
SET @sql = 'SELECT * FROM ' + @mytable
EXEC sp_executesql @sql

I have declared a temporary table (@mytable) in a sp and want to use it
within a dynamic SQL statement.
It doesn't seem to like it.
Complains that the vaiable @mytable is not defined.

What is wrong?

you can not reference a table variable inside dynamic sql , if the variable
is defined ouside the scope of dynamic sql statement.

ex:
declare @var table (idd int)

exec ('select * from @var') --error out, because @var is defined outside the
scope.

exec ('declare @var table (idd int) insert into @var values (1) select *
from @var') --successful
