data type mismatch in criteria expression in ms access

Problem / Error:

When you try to access the data from the Microsoft Access database from any language like C#, VB.Net, VB6 etc, You may encounter the error saying - data type mismatch in criteria expression .
This happens when you are executing the query involving the column with data type set as Date/Time in access database.

For example -Consider below query.

Select * from student where joining_date = '12-01-2013' 

Executing above query will give you the error saying data type mismatch in criteria expression.

Solution:
To fix above issue, you will have to re-write the query as mentioned below.

Select * from student where joining_date = #12-01-2013#

Thus we have to use # at the start and end of the date value. This will fix the issue.
