One thing I think people forget is that there are two forms of SQL inserts.

Either

Code:

INSERT INTO Customers
VALUES ('Cardinal', 'Tom B. Erichsen', 'Skagen 21', 'Stavanger', '4006', 'Norway');

Or

Code:

INSERT INTO Customers (CustomerName, ContactName)
VALUES ('Cardinal', 'Tom B. Erichsen');

The second method explicitly names the columns being given data and sets the other columns to default values. This means that if the table is changed to have additional columns added the insert will still function.

For instance at one point all one needed was

Code:

INSERT INTO user (UserID, UserKey, UserDisplayName, UserEmail)
values("00000000-0000-0000-0000-000000000000","00000000-0000-0000-0000-000000000000","MyDummyUser@dummy.com","MyDummyUser@dummy.com")

If now additional columns need explicit values they just need to be added to both the list of columns and the value statement
