Replication Server supports all of the Adaptive Server datatypes.
User-defined datatypes are not supported. The timestamp, double precision, nchar, and nvarchar datatypes are indirectly supported by mapping them to other datatypes. Columns using the timestamp datatype are mapped to varbinary(8).
Refer to “Datatypes” in Chapter 2, “Topics,” in the Replication Server Reference Manual for more information about the supported datatypes, including how to format them.
