Data Set Options for Relational Databases 4 Overview 207About the Data Set Options for Relational DatabasesOverviewYou can specify SAS/ACCESS data set options on a SAS data set when you accessDBMS data with the SAS/ACCESS LIBNAME statement. A data set option appliesonly to the data set on which it is specified, and it remains in effect for the duration ofthe DATA step or procedure. For options that you can assign to a group of relationalDBMS tables or views, see “LIBNAME Options for Relational Databases” on page 92.Here is an example of how you can SAS/ACCESS data set options:libname myoralib oracle;proc print myoralib.mytable(data-set-option=value)You can also use SAS/ACCESS data set options on a SAS data set when you accessDBMS data using access descriptors, see “Using Descriptors with the ACCESSProcedure” on page 907. Here is an example:proc print mylib.myviewd(data-set-option=value)You cannot use most data set options on a PROC SQL DROP (table or view)statement.You can use the CNTLLEV=, DROP=, FIRSTOBS=, IN=, KEEP=, OBS=, RENAME=,and WHERE= SAS data set options when you access DBMS data. SAS/ACCESSinterfaces do not support the REPLACE= SAS data set option. For information aboutusing SAS data set options, see the SAS Language Reference: Dictionary.The information in this section explains all applicable data set options. Theinformation includes DBMS support and the corresponding LIBNAME options, andrefers you to documentation for your SAS/ACCESS interface when appropriate. For alist of the data set options available in your SAS/ACCESS interface with default values,see the reference section for your DBMS.Specifying data set options in PROC SQL might reduce performance, because itprevents operations from being passed to the DBMS for processing.
