The FairCom DB SQL import utility, ctsqlimp, utility “registers” or links existing c-tree files with a FairCom DB SQL database without modifying the table structure such that the files remain accessible from the original application and also accessible from FairCom DB SQL.
For more information about this utility, see ctsqlimp - SQL Import Utility.
FairCom DB has the ability to "Auto Import" a table into SQL at the time it is accessed. To use this feature, you will need to supply a SQL callback library providing the information needed to import the database, such as the database name, the table owner, and the table name. At runtime, when the SQL parser encounters an object not present as a table in the system tables, it calls the registered function and imports the database.
