  • Access 2019, Access 2016, Access 2013, Access 2010, Access 2007, Access 2003, Access XP, Access 2000

Example

Let's look at how to use the IsDate function in MS Access:

Result: TRUE

IsDate ("Tech on the Net")
Result: FALSE

IsDate ("January 3, 2004")
Result: TRUE

The IsDate function can be used in VBA code in Microsoft Access.

For example:

Dim LValue As Boolean

LValue = IsDate("Tech on the Net")

In this example, the variable called LValue would contain FALSE as a value.

Example in SQL/Queries

You can also use the IsDate function in a query in Microsoft Access.

For example:

Microsoft Access

In this query, we have used the IsDate function as follows:

Expr1: IsDate([Description])

and

Expr2: IsDate(#03/01/2003#)

The first IsDate function will evaluate whether the Description field is a valid date and display the results in a column called Expr1. You can replace Expr1 with a column name that is more meaningful.

For example:

ValidDate: IsDate([Description])

The results would now be displayed in a column called ValidDate.

The second IsDate function will evaluate whether the value #03/01/2003# is a valid date and return the results in a column called Expr2.
