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.


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.
