Insert null/empty value in sql datetime column by default

How do I create a table in SQL server with the default DateTime as empty, not 1900-01-01 00:00:00.000 that I get?

I mean, if there is no value inserted, the default value should be null, empty, etc.

if there is no value inserted, the default value should be null,empty

In the table definition, make this datetime column allows null, be not defining NOT NULL:

...
DateTimeColumn DateTime,
...

I HAVE ALLOWED NULL VARIABLES THOUGH.

Then , just insert NULL in this column:

INSERT INTO Table(name, datetimeColumn, ...)
VALUES('foo bar', NULL, ..);

Or, you can make use of the DEFAULT constaints:

...
DateTimeColumn DateTime DEFAULT NULL,
...

Then you can ignore it completely in the INSERT statement and it will be inserted withe the NULL value:

INSERT INTO Table(name, ...)
VALUES('foo bar', ..);

Even if your column is nullable, inserting an empty string will set the value to 1900-01-01 00:00:00.000. Make you insert real nulls not strings, then the db will store a null.
