Can you show me an example?
I just tried it, using a user-defined type mapped to varchar(30), and
type_info() returns "char" (which is correct).
DBD::Sybase uses Sybase's sp_datatype_info catalog stored proc to get
the datatype information - this is so that we return the same
information that an ODBC or JDBC driver would get.
