Remarks
The MsiDatabaseApplyTransform function delays transforming tables until it is necessary. Any tables to be added or dropped are processed immediately. However, changes to the existing table are delayed until the table is loaded or the database is committed.
An error occurs if MsiDatabaseApplyTransform is called when tables have already been loaded and saved to storage.
Because the list delimiter for transforms, sources and patches is a semicolon, this character should not be used for filenames or paths.
This function cannot be called from custom actions. A call to this function from a custom action causes the function to fail.
If the function fails, you can obtain extended error information by using MsiGetLastErrorRecord.
Note
The msiquery.h header defines MsiDatabaseApplyTransform as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
