What you can do

You can:

Allow updates in a form associated with multiple tables or a view; you can define one of the tables as being updatable
Prevent updates in a form associated with one table
Prevent updates to specific columns in a form that is associated with an updatable table
Specify which columns uniquely identify a row to be updated
Specify which columns will be included in the WHERE clause of the UPDATE or DELETE statement InfoMaker generates to update the database
Specify whether InfoMaker generates an UPDATE statement, or a DELETE then an INSERT statement, to update the database when you modify the values in a key column

Updatability of views Some views are logically updatable; some are not. For the rules your DBMS follows for updating views, see your DBMS documentation.

To specify update characteristics for a form:

Select Design>Update Properties from the menu bar.
If the form is a master/detail style, select the data source as prompted.

The Specify Update Properties dialog box displays.
To prevent updates to the data, make sure the Allow Updates box is not selected.

To allow updates, select the Allow Updates box and specify the other settings as described below.
Click OK.

Changing tab values

InfoMaker does not change the tab values associated with columns after you change the update characteristics of the form. If you have allowed updates to a table in a multitable form, you should change the tab values for the updatable columns so that you can tab to them.

For more information, see “Defining the tab order in a form”.
