This tutorial will show you how to temporarily hold data into temporary table in SQL Server?
Temporary table is similar to table variable however, temporary table is not created in memory but it gets created physically in the database and it remains unless the current session ends or it is dropped explicitly.
CREATE TABLE #myTempData
(
DetailId int,
FullName varchar(50)
)
INSERT INTO #myTempData
SELECT EmployeeID, FirstName + ' ' + LastName
FROM [NORTHWND].[dbo].[Employees]
SELECT * FROM #myTempData
-- DROP this temp table now
DROP table #myTempData
Temporary table name is prefixed with # character.
In above case, we have create a table named #myTempData with DetailId and FullName fields and inserting record from Employees table then selecting its records and when we are intended to not use this temp table any more, we have dropped it.
