ULDatabaseSchema class
ApplyFileWithParms( parms As ULConnectionParms ) As Boolean
Member of UltraliteActiveX.ULDatabaseSchema
Upgrades the schema of this database using the parameter object Parms, which points to the schema file(s) you are applying to the database. This method is only useful on those occasions where you want to modify your existing database structure.
CautionApplyFileWithParms is very safe in the hands of an informed programmer. Do not delete columns unthinkingly unless you are willing to accept data loss, as data loss can occur under a number of circumstances including (1) if columns are deleted, or (2) if the data type for a column is changed to an incompatible type or (3) if you upgrade an 8.0.2 database using ApplyFile in UltraLite 9.0. |
parms The object identifying the schema file to apply.
True if successful.
False if unsuccessful.
