You do not have to drop the table variable because as soon as the statement execution is completed, the table variable does not exist. Once you have successfully created a table variable, you can query the same table variable via following select statement. Table variables are also temporary objects and they are created as with DECLARE keywords. Just remember, any table which is created with # in the beginning is a temporary table and it is created in the temp database. If you want to explicitly drop the table you can execute the following command.
The table will be automatically dropped when you close the connection. SELECT * FROM #TempTableĪs long as the session is active you can query the same table multiple times. Now you can query the table just like a regular table by writing select statement. CREATE TABLE #TempTable (ID INT IDENTITY(1,1))
