In Access, the IsDate function returns a value indicating whether or not a variant argument can be converted to a date.
The syntax for the IsDate function is:
IsDate ( expression )
The required expression argument is a date expression or string expression recognizable as a date or time.
Example
IsDate (#10/5/2006#) returns TRUE
IsDate("It's a date") returns FALSE
IsDate("May 25, 2006") returns TRUE
VBA Code
MyResult = IsDate(“It’s a date”)
The IsDate function can be also used in VBA code. Now the MyResult variable would contain FALSE as a value.
SQL query
You can also use the IsDate function in a query.
SELECT IsDate([FirstName]) AS Expr1, IsDate([BirthDate]) AS Expr2, IsDate(#10/10/2000#) AS Expr3
FROM EmployeeAddressTable
