I looked at header, documentation and googled... there is no direct
support for bigint in dblib... you should use numeric. DBINT8/DBINT64
would be an extension to dblib. It seems Sybase defined support for
bigint only for ctlib (odbc already support 64bit integers) using
CS_BIGINT. We could define an extension for this binding and type.
tds_willconvert and tds_convert already support SYBINT8 so the
extension would affect only dblib library not libTDS code.
