Applies To
OBfile
Description
Returns true if the OBFile points to a BFILE that exists on the server.
Usage
bool Exists(void) const throw(OException)
Arguments
none
Remarks
Read privileges on the directory where the BFILE is located are required to
use this property. The operating system-specific permissions must have been set
for the directory to make sure that the user can read the directory.
Appropriate privileges must also have been set up in the database. For
example, to ensure that a user (scott) can read a directory (BfileDirectory) through
the Exists property, the following SQL statement needs to be executed:
GRANT READ ON DIRECTORY BfileDirectory TO scott;
