string setUpgradeMethod ( optional string $method = '' )
Sets the method to be used for upgrading an existing database
Use this method to specify how existing database objects should be upgraded. The method option can be set to one of the following:
|ALTER||attempts to alter each database object directly|
|REPLACE||attempts to rebuild each object from scratch|
|BEST||attempts to determine the best upgrade method for each object|
This method is not yet used by AXMLS, but exists for backward compatibility. The ALTER method is automatically assumed when the adoSchema object is instantiated; other upgrade methods are not currently supported.
