Q130303: PRB: Default Values Not Checked for Integrity by Visual FoxPro

Article: Q130303
Product(s): Microsoft FoxPro
Version(s): WINDOWS:3.0
Operating System(s): 
Keyword(s): 
Last Modified: 10-FEB-2000

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual FoxPro for Windows, version 3.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you provide a default value property for a field in a Visual FoxPro table,
Visual FoxPro does not check to see if the default value passes the field
validation rule.

RESOLUTION
==========

The developer should be sure that the default value property for a field does
not violate the field validation rules.

STATUS
======

This behavior is by design.

MORE INFORMATION
================

Ensuring that field default values do not violate field validation rules is the
responsibility of the programmer.

Steps to Reproduce Behavior
---------------------------

1. Create a new database and table.

2. Add a new field (named nfld1, type numeric, width 4).

3. As a Validation rule, type:

  " IIF(nfld1 > 100, .T., .F.) " (without the quotation marks)

4. As a Default Value, type:

  " 99 " (without the quotation marks)

5. Save the table structure, and append a new record to the table. An error
  occurs because the default value 99 violates the validation rule that nfld1
  must be greater than 100.
