Introduction
I have a table with Identity Columns and others have some Default values. I want to insert only the default values with the table.
In this article we are going to discuss it. Hope it will be interesting.
How I Do That
Step – 1 [ Create the Base Table ]
IF OBJECT_ID('tempdb..#temp_Table')IS NOT NULL
BEGIN
DROP TABLE #temp_Table;
END
GO
CREATE TABLE #temp_Table
(
IDNO INT NOT NULL IDENTITY PRIMARY KEY,
ENTRYDATE DATE NOT NULL DEFAULT GETDATE(),
SEX CHAR(1) NOT NULL DEFAULT('M')
);
Here if we see the table object definition carefully we find that
IDNO
|
IDENTITY in nature (Auto Increment)
|
ENTRYDATE
|
With Default Values GETDATE(), always give the current date.
|
SEX
|
With Default Values ‘M’
|
So we are not going to insert anything, we are just using the Default values only to populate the table.
Step-2 [ How We DO THAT ]
INSERT INTO #temp_Table DEFAULT VALUES;
Step-3 [ Observing the Output ]
SELECT * FROM #temp_Table;
IDNO ENTRYDATE SEX
