DOCUMENT:Q139158 11-FEB-2000 [foxpro] TITLE :How to Add Fields to a Table in Visual FoxPro Programmatically PRODUCT :Microsoft FoxPro PROD/VER:WINDOWS:3.0 OPER/SYS: KEYWORDS:kbcode ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual FoxPro for Windows, version 3.0 ------------------------------------------------------------------------------- SUMMARY ======= In previous versions of FoxPro, the only way to alter the structure of a table programmatically was to create a new table that contained the new structure and then append the data from the old table. Visual FoxPro now includes the ALTER TABLE command, which allows you to alter the structure of an existing table programmatically. This article shows by example how to add a field to an existing table. MORE INFORMATION ================ This example uses the Customer.dbf table that is part of the Testdata.dbc database. These files are located in the \Vfp\Samples\Data directory. The following code adds a new field named Newfield to the Customer.dbf table. The new field is a character field with a width of 20. OPEN DATA testdata USE customer ALTER TABLE customer ADD COLUMN Newfield C(20) After running this code, use the MODIFY STRUCTURE or BROWSE command to see the changes to the table structure. For more information on the ALTER TABLE command, please see the ALTER TABLE command topic in the Visual FoxPro Help file.
