SET BASED LOGGING Parameter

When set-based logging is enabled, a separate log entry is generated for all rows in each table affected by EIM. This allows greater performance improvement because EIM can perform the operations as set operations in SQL, without resorting to row-by-row processing to support the transaction log. Set-based transaction logging is most useful when a table is read-only to mobile Web clients. Set-based logging is always the default for merge. The SET BASED LOGGING parameter must be set to FALSE to allow transaction logging for merge.
