Adaptive Server limits the number of expressions in the where clause to 1024. For warm standby applications, you must use replication definitions to replicate tables with more than 1024 columns, and make sure that the primary key is not more than 1024 columns. Adaptive Server generates an error if the Replication Server where clause has more than 1024 columns.
See “Using replication definitions to optimize performance” for more information about the primary key and replication into the standby database.
