RDBMS-specific SQL functions are
functions that cannot be used on ALL databases supported by USoft.
These functions may be convertible or non-convertible.
Convertible functions will be
converted automatically by USoft if the application is ported to
another type of RDBMS than it was developed on, and that other
RDBMS has an equivalent function. A particular function may thus be
convertible to all supported RDBMSs, or it may only be convertible
to some.
Non-convertible functions will
NOT be converted by USoft if the application is ported to another
type of RDBMS.
When developing a portable
application, if you need to use an RDBMS-specific function, make
sure it is convertible to the RDBMS(s) you wish to port the
application to.
