Replication Agent processes Microsoft SQL Server transactions and passes transaction information to the primary Replication Server.
The primary Replication Server uses the datatype formats specified in the replication definition to receive the data from Replication Agent.
The following table describes the default conversion of Microsoft SQL Server datatypes to Sybase Replication Server datatypes.
