Abstract
System, method, computer program product embodiments and combinations and sub-combinations thereof for logging of data manipulation language (DML) statements are described herein. An embodiment includes a database engine, a replication agent and a replication server which replicates data from the database engine to one or more replicate databases. The database engine writes parsed query information into a transaction log so that a process of replication agent may read the parsed query information and forward it to the replication server. The database engine writes all log records associated with a statement in a manner that allows the replication server to distinguish if those log records belong to same statement. In another embodiment, replication agent selectively sends SQL statement information to the replication server based on the replication server architecture.
