What features are missing compared to the vendors implementations?
In no particular order: • MARS • DB-Library browse API • Parameterized queries in CT-Library with TDS 7.0+ (i.e. Microsoft servers) • CT-Library money functions For specific functions, consult doc/api_status.txt in your distribution. Very few programs actually need the missing functionality. Parameterized CT-Library queries would benefit Perl DBD::Sybase users, but the functionality would require departing from Sybase’s documented API. MARS comes up because there must be thousands of people whom Microsoft has convinced they need it, but the benefits are meager compared to the complexity.
