Q150434: PRB: Field Width Increases When Use Visual FoxPro ODBC Driver

Article: Q150434
Product(s): Microsoft FoxPro
Version(s): 5.0
Operating System(s): 
Keyword(s): 
Last Modified: 01-NOV-2001

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

- Microsoft Visual FoxPro for Windows, version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When the Visual FoxPro ODBC driver is used to create a numeric field of width 5
with decimal 2, the driver adds two places to the width in order to ensure that
the length is of sufficient size. Two positions are added to compensate for the
sign and decimal that is normally included in the length in native Visual
FoxPro.

CAUSE
=====

When a table is created with a numeric field, the decimal point and sign are
counted in the width by Visual FoxPro. However, the ODBC standards do not
specify how the decimal and sign should be specified when creating a table.

STATUS
======

This behavior is by design.

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

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

1. Create a datasource named temp that is set up for free tables and that points
  to the C:\Temp directory.

2. Run the following program:

     h=SQLCONNECT("temp","","")
     ?SQLEXEC(h,"CREATE TABLE ztest (nfield N(5,2))")
     ?SQLDISCONNECT(h)
     USE c:\temp\ztest
     MODIFY STRUCTURE

Notice that the width is 7 instead of 5. The width was increased by two.
