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

406 DBIDIRECTEXEC= System Option 4 Chapter 12Before an SQL statement can be processed, all librefs that are associated with thestatement must reference compatible data sources. For example, a CREATE TABLE ASSELECT statement that creates an Oracle table by selecting from a SAS table is notsent to the database for execution because the data sources are not compatible.The libref must also use the same database server for all compatible data sources.ExampleThis example creates a temporary table from a SELECT statement using theDBIDIRECTEXEC system option.libname lib1 db2 user=andy password=andypwd datasrc=sample connection=global;libname lib2 db2 user=mike password=mikepwd datasrc=sampleconnection=global dbmstemp=yes;data lib1.tab1;a=1;b=’one’;run;options dbidirectexec sastraceloc=saslog;proc sql;create table lib2.tab1 asselect * from lib1.tab1;quit;In this next example, two librefs point to the same database server but use differentschemas.libname lib1 db2 user=henry password=henrypwd datasrc=sample;libname lib2 db2 user=scott password=scottpwd datasrc=sample;data lib1.tab1;a=1;b=’one’;run;options dbidirectexec sastraceloc=saslog;proc sql;create table lib2.tab2 asselect * from lib1.t1;quit;This example shows how a statement can be passed directly to the database forexecution, if you specify DBIDIRECTEXEC.libname company oracle user=scott pw=tiger path=mydb;proc sql;create table company.hr_tab asselect * from company.empwhere deptid = ’HR’;quit;
