db_null (public, deprecated)

 db_null

Defined in packages/acs-tcl/tcl/01-database-procs.tcl

Deprecated. Invoking this procedure generates a warning.

Returns:
an empty string, which Oracle thinks is null. Deprecated: This routine was invented to provide an RDBMS-specific null value but doesn't actually work. I (DRB) left it in to speed porting - we should really clean up the code and pull out the calls instead, though.
