EFFICIENT BULK LOADING MULTIPLE ROWS OR PARTITIONS FOR A SINGLE TARGET TABLE

Abstract:

A computer-implemented system and method process insertions into a target table of a target database system. A single query language INSERT statement is received that is related to a source partition of a source table in a source database system that identifies a block of data (BOD), having a partition identifier (PID), to be inserted into the target table. The INSERT statement contains no literal PID. Responsive to receiving the INSERT statement, a processor receives the BOD from the source table via a data stream, and inserts the BOD into the target table. This reduces the overhead associated with using an INSERT statement to insert multiple rows of data into a target table.
