258 BL_INDEX_OPTIONS= Data Set Option 4 Chapter 11BL_INDEX_OPTIONS= Data Set OptionLets you specify SQL*Loader Index options with bulk loading.Alias: SQLLDR_INDEX_OPTION=Default value: noneValid in: DATA and PROC steps (when accessing DBMS data using SAS/ACCESSsoftware)DBMS support: OracleSyntaxBL_INDEX_OPTIONS=any valid SQL*Loader Index optionsegment-nameSyntax Descriptionany valid SQL*Loader Index optionThe value that you specify for this option must be a valid SQL*Loader index option,such as one of the following. Otherwise, an error occurs.SINGLEROW Use this option when loading either a direct path with APPENDon systems with limited memory or a small number of recordsinto a large table. It inserts each index entry directly into theindex, one record at a time.SORTEDINDEXESDetailsBy default, DQL*Loader does not use this option to appendrecords to a table.This clause applies when you are loading a direct path. It tellsthe SQL*Loader that the incoming data has already been sortedon the specified indexes, allowing SQL*Loader to optimizeperformance. It allows the SQL*Loader to optimize index creationby eliminating the sort phase for this data when using thedirect-path load method.To specify this option, you must first set BULKLOAD=YES.You can now pass in SQL*Loader index options when bulk loading. For details aboutthese options, see the Oracle utilities documentation.ExampleThis example shows how you can use this option.proc sql;connect to oracle ( user=scott pw=tiger path=alien);execute ( drop table blidxopts) by oracle;execute ( create table blidxopts ( empno number, empname varchar2(20))) byoracle;execute ( drop index blidxopts_idx) by oracle;
