Truncate Tables Button
Click this button to delete all the data in the selected _all tables at the current site.
This button only truncates if there is an actual table in the current site. This is true in the master site of a shared environment, or in a multi-site, multi-database environment. In an environment that has a shared view, a delete on the current site is performed instead.
If you want to perform a delete on another site, use the delete buttons instead of the
button.For an example that shows how this button is used, see Using the Update _All Tables Form.
