SAS/ACCESS 9.2 for Relational Databases: Reference, Fourth Edition

SAS/ACCESS Interface to Oracle 4 Passing SAS Functions to Oracle 723This next example uses the APPEND option to append rows from the INVDATA dataset, which was created previously, to an existing Oracle table named INVOICE.proc dbload dbms=oracle data=invdata append;user=testuser;orapw=testpass;path=’myorapath’;table=invoice;load;run;Maximizing Oracle PerformanceThere are several measures you can take to optimize performance when usingSAS/ACCESS Interface to Oracle. For general information about improvingperformance when using SAS/ACCESS engines, see Chapter 4, “PerformanceConsiderations,” on page 35.SAS/ACCESS Interface to Oracle has several options that you can use to furtherimprove performance.3 For tips on multi-row processing, see these LIBNAME options: INSERTBUFF,UPDATEBUFF, and READBUFF.3 For instructions on using the Oracle SQL*Loader to increase performance whenloading rows of data into Oracle tables, see “Passing Functions to the DBMS UsingPROC SQL” on page 42.If you choose the transactional inserting of rows (specify BULKLOAD=NO), you canimprove performance by inserting multiple rows at a time. This performanceenhancement is comparable to using the Oracle SQL*Loader Conventional Path Load.For more information about inserting multiple rows, see the INSERTBUFF= option.Passing SAS Functions to OracleSAS/ACCESS Interface to Oracle passes the following SAS functions to Oracle forprocessing. Where the Oracle function name differs from the SAS function name, theOracle name appears in parentheses.
