You can maximize the performance of certain SQL statements by specifying to execute
them asynchronously, in parallel.
SPD Server provides the BEGIN ASYNC OPERATION and END ASYNC OPERATION statements to delimit
the
block of statements that are intended for asynchronous,
parallel execution. The BEGIN ASYNC OPERATION statement marks the beginning of the statement block.
The END ASYNC OPERATION statement marks the end of the statement block.
For examples of how
the BEGIN ASYNC OPERATION and END ASYNC OPERATION statements are used,
see “Creating Asynchronous Operation Blocks” in X.
