SQL Default Constraint is used to assign default values to the SQL table columns. In general, every column accepts either Nulls, or a Value. If the user forgot to enter the value then SQL Server will assign NULL value to the column. In those cases, we can use the SQL Server Default constraint to replace those Nulls with default value.

In this article we will show you, how to assign default values in SQL server with examples.
