Return Value
This method does not return a value.Remarks
The ApplyTransform method delays transforming tables until the last possible moment. The steps taken in ApplyTransform are to immediately transform the table and column catalogs for the database. The table and column catalogs are updated according to which table is added or deleted and which column is added (no deletion of columns is allowed). If a table is currently loaded in memory and needs to be transformed, it is transformed. Otherwise, the table state is set to that requiring a transform so that when the table is loaded, or when the database is committed, the transform is applied. Transform in this instance means that the actual (row) data of the table is added, deleted, or updated.
If the method fails, you can obtain extended error information by using the LastErrorRecord method.
