THis code explain about table variable used in sql server
 



Table Variable is used to store set of rows temporarily.

Table variables memory allocated in the ram.


Disadvantages:
--------------

Table variable cannot maintained relationship with other table variable.


You create a table variable the same way you create any other variable: using the declare statement:


declare @TableVar table (CustomerID nchar(5) NOT NULL)


This declares a table variable named @TableVar that we can use in place of a temporary table. You can use a table variable for just about anything you'd use a regular table.
