How to insert N rows of default values into a table
I have a table containing an identity column as well as a column representing the creation date:
CREATE TABLE dbo.OrderStatus ( OrderStatusId int IDENTITY(1, 1) NOT NULL, CreationDate datetime NOT NULL default GETDATE(), CONSTRAINT PK_OrderStatus PRIMARY KEY(OrderStatusId) )
Since the identity column generates a value by itself and the CreationDate is always going to be the current date (
GETDATE()), I can add a row thanks to
INSERT INTO dbo.OrderStatus DEFAULT VALUES;
But what can I do if I want to add, let's say, three records?
Current solution (edited some input since it didn't make any sense)
For now, in order to do what I want, I add several rows with
INSERT INTO dbo.OrderStatus (CreationDate) VALUES (GETDATE()), (GETDATE()), (GETDATE())
Although, I'd prefer to know the equivalent of
INSERT INTO .. DEFAULT VALUES for multiple rows, in case that I add another column with a default value later on.
Is there a way to insert N rows into a table with
DEFAULT VALUES or in a similar way?
You can use your original definition and just use a while loop, for example
DECLARE @OrderStatus TABLE ( OrderStatusId int IDENTITY(1, 1) NOT NULL, CreationDate datetime NOT NULL DEFAULT GETDATE() --CONSTRAINT PK_OrderStatus PRIMARY KEY(OrderStatusId) -- this can be uncommented if creating a real table. ) DECLARE @i int = 0; WHILE @i < 100 -- insert 100 rows. change this value to whatever you want. BEGIN INSERT @OrderStatus DEFAULT VALUES SET @i = @i + 1; END SELECT * FROM @OrderStatus
Here's how to do it using a recursive CTE:
;with cteNums(n) AS ( SELECT 1 UNION ALL SELECT n + 1 FROM cteNums WHERE n < 100 -- how many times to iterate ) INSERT @OrderStatus SELECT * FROM cteNums
Just note that for the CTE you'd have to specify
OPTION(MAXRECURSION ...) if it's greater than 100. Also note that even though you're selecting a list of numbers from the CTE, they don't actually get inserted into the table.
