What is datetime precision in SQL?
Datetime precision in SQL refers to the level of detail stored in datetime values, such as seconds, milliseconds, or even nanoseconds.
How do I set the precision for a datetime column?
You can set the precision by specifying it in the column definition, like DATETIME(3) for milliseconds.
What happens if I don't specify precision?
If you don't specify precision, SQL Server defaults to a precision of 7, which includes fractions of a second up to 100 nanoseconds.
Can I change the precision of an existing datetime column?
Yes, you can change the precision using the ALTER TABLE statement, but be cautious as it may affect existing data.
