Enterprise Manager is a powerful utility to access and to control Microsoft SQL 2000 or later. One of a useful tool in Enterprise Manager is data browser. It lets us to query and to modify data in fields. I have some problems about entering data in fields. In some cases, fields are nullable. Initially, it might be null and then I entered something. Once I want to set it back to null, it is not possible to just remove everything I entered. The reason of this problem is the difference of empty string and null. To reset data back to null, you have to press CTRL+0.
