You can transfer data in two directions:
A transfer to statement transfers data from the primary database to the secondary database. The primary database becomes the source database to the secondary database, which is the target.
A transfer from statement transfers data from the secondary database to the primary database. The secondary database becomes the source database to the primary database, which is the target.
For example, when you execute a bulk copy transfer from statement, the secondary database (either ASE or another database) is the source of the data to be transferred. The primary database becomes the destination database, or target.
For the implications of using one transfer direction over another, see “Datatype conversion for transfer processing”.
Sybase recommends that you use the transfer from command from the primary database when you transfer data between two access services. Using transfer from guarantees native datatype mapping and returns the proper datatype result set.
