SUMMARYMicrosoft FoxPro supports two types of .cdx compound index files: structural and independent (nonstructural). An independent compound index file is created by specifying an OF clause in the INDEX command. Unlike the structural index file, an independent index file is not opened when the associated database is opened. To open the index, use the SET INDEX command or the INDEX clause of a USE command.
MORE INFORMATIONThe information below demonstrates how to create, open, and specify the order of an independent .cdx file with multiple tags. To create an independent index for a database, use commands such as the following. Note that the name of the .cdx file cannot be the same as the name of the database.
USE OFFICES INDEX ON ONO TAG ONO OF Xoffices.cdx INDEX ON CITY TAG CITY OF Xoffices.cdx INDEX ON STATE TAG STATE OF Xoffices.cdxTo open a database with an associated independent .cdx file, use code such as the following:
USE OFFICES INDEX Xoffices.cdx * Set the order and list to demonstrate each tag is correct. SET ORDER TO TAG ONO OF Xoffices.cdx LIST SET ORDER TO TAG CITY OF Xoffices.cdx LIST SET ORDER TO TAG STATE Of Xoffices.cdx LIST |
