Ooops. Let me re-state: This is because the *implementation* of BLOBS
is not defined in the SQL standard, and BLOBs are IMHO a bad idea for
relational database design, as they violate Codd's Rules. Thus the
implementation of, anf functions and operators for BLOBs are entirely
proprietary to the RDBMS platform.
The solution to this is not to use BLOBs, but rather to use file system
handles for the location of the binary data on the server. This way,
all you need is DOS-to-UNIX and UNIX-to-DOS translation for the
filesystem handles, something easily accomplished through
string-manipulation functions or stored procedures.
