The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.

Applies to: Microsoft SQL Server 2008 and above.
 

Problem Description.
 

Using SQL Server Management Studio, we created the following piece of T-SQL code and execute it.
 

DECLARE @DATETIME datetime = '1700-01-01'

SELECT @DATETIME

We received the following error message:


Msg 242, Level 16, State 3, Line 1
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.

(1 row(s) affected)


Cause.


The datetime data type does not accept dates earlier than January 1, 1753.


Solution.

To solve this problem, you can use the new "date" data type introduced on SQL Server 2008.

For example:
 

DECLARE @DATETIME date = '1752-12-31'

SELECT @DATETIME

DECLARE @DATETIME_B date = '0001-01-01'

SELECT @DATETIME_B

The results are:


----------
1752-12-31

(1 row(s) affected)


----------
0001-01-01

(1 row(s) affected)
