operation
- is the operation to be invoked for the statement. It can be one of the ReplicationConstants
defined actions INSERT, UPDATE DELETE, CREATE, ALTER or DROP.conn
- The Database connection object. The implementor is not responsible for cleaning up the resource,
this is done by the invoker.tableDescription
- the description (metadata) of the table from which the current table is coming from,
if the row would contain entries (columns) coming from more than one table, then null is passed. The
ReplicationWriter could also pass null if the operation is a CREATE and the table does not exist yet
in the replica database. As this is created out of the metadata information of the destination, the
catalog-, schema-, table- and column names are already the ones after any mapping modification.currentRow
- The row which currently will be processed. It can be null if the operation is a CREATE,
ALTER or DROP. The columns specified in this row are already modified according to the mapping.
java.lang.Exception
- thrown if something went wrong in the implementation. If it is thrown, then the operation is
not performed and a rollback of the entire transaction is done.public void postStatement(java.lang.String operation, java.sql.Connection conn, SqlInfo info, SqlDescription tableDescription, SqlRow currentRow) throws java.lang.Exception
