Creating a Replication Definition

Create a replication definition to describe a replicated object. You can create replication definitions for databases, functions, or tables.

1. Use isql to log in to Replication Server.
2. Create a replication definition for the warm standby for table “t1”:

   create replication definition t1_ws_repdef
   with primary at pubs2a.pubs2s
   with all tables named t1
   (a integer, b char(10), c datetime)
   primary key (a)
   send standby replication definition columns
   replicate SQLDML
   go
   Replication definition ‘t1_ws_repdef’ is created.

   Note: To replicate using SQL statement replication, which is available only in Adaptive Server version 15.0.3 and later, use the replicate SQLDML clause.
3. Update the row in table “t1”:

   update t1 set c = getdate()
   go

4. Compare the trace output with the output that was generated before the replication definition was created:

   T. 2009/10/28 22:10:43. (138): Command(s) to
   'wingak1505i.pubs2':
   T. 2009/10/28 22:10:43. (138): 'begin transaction [0a]
   update dbo.t1 set a=1, b='first row', c='20091028
   22:10:42:383' where a=1 '

   The where clause in the update statement, now contains only column “a” because the replication definition specified that column “a”, uniquely identifies the row.
