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. Date Time Column Date Time. I HAVE ALLOWED NULL VARIABLES THOUGH. Then, just insert NULL in this column: INSERT INTO Table(name, datetime Column.) VALUES foo bar NULL. Or, you can make use of the DEFAULT constaints. Date Time Column Date Time 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'.
I have a stored procedure ( SS2k8) with a couple table-valued parameters that will sometimes be null or empty. I have seen this Stack Overflow post that says that null/empty TVPs should simply be omitted from the calling parameter list. My problem is that I can't figure out how to check for empty or null inside the stored procedure as IF tvp IS NULL) fails on procedure creation with the message ' Must declare the scalar variable @tvp '. Do I have to do a SELECT COUNT on the TVP and check for zero? Code excerpt: CREATE PROCEDURE [foo] tvp [ Tvp Type] READONLY) AS IF tvp IS NOT NULL) - doesn't work BEGIN - lots of expensive processing END ELSE BEGIN - a little bit of cheap processing END.
