Undefined function 'IsDBNull' in expression

I have a sql statement that pulls data from ms access db if the date in the table is null or greater or equals to today's date.
I am converting asp to asp.net. In my WHERE clause I had
WHERE  (isNull(endDate)  OR endDate >= Date())

after converting to .net I got

WHERE (IsDBNull(endDate) OT endDate >= DateTime.Now)

But now I'm getting an error Undefined function 'IsDBNull' in expression.

I mported System.DBNull.
What am I doing wrong?

The WHERE clause will run on the SQL server and must use SQL syntax...

Depending on your version of SQL that may change however this will work on SQL 6.5 or above..

           WHERE  ((endDate Is Null)  OR endDate >= GetDate() )

Have Fun,

if this is from a sql statement change it back to isnull.

if this is vb code you can use
endDate = DBNull.Value

to see if a value is null

where do I put this line endDate = DBNull.Value?
in my sql statement?


I have "SELECT * FROM Table1 WHERE (IsDBNull(endDate) OT endDate >= DateTime.Now)"
