Then define given columns to :
- not accept null values
- have a default one

Example :

SQL

CREATE TABLE Dummy (
   DummyId int NOT NULL IDENTITY(1,1)
  ,IntColumn int NOT NULL DEFAULT 0
  ,StringColumn nvarchar(8) NOT NULL DEFAULT ""
  ,StringColumn2 nchar(3) NOT NULL DEFAULT "xxx"
  ,DateTimeColumn datetime NOT NULL DEFAULT GETDATE()
  -- etc...
)

Hi,
add a default consraint to that column, either when creating the table:

SQL

CREATE TABLE CUSTOMERS(
       ID   INT              NOT NULL,
       NAME VARCHAR (20)     NOT NULL,
       AGE  INT              NOT NULL,
       ADDRESS  CHAR (25) ,
       SALARY   DECIMAL (18, 2) DEFAULT 5000.00,       
       PRIMARY KEY (ID)
);

or later:

SQL

ALTER TABLE CUSTOMERS
   MODIFY SALARY  DECIMAL (18, 2) DEFAULT 5000.00;

SQL - DEFAULT Constraint [^]
