LIBNAME statement pass-thru SQL query
LIBNAME statement
LIBNAME MYORALIB ORACLE USER=MYUID PW=MYPASSWORD PATH='@OraInfo' SCHEMA=MYSCHEMA;
LIBNAME statement
14 LIBNAME MYORALIB ORACLE USER=MYUID PW=XXXXXXX PATH='@OraInfo' SCHEMA=MYUID
NOTE: Libref MYORALIB was successfully assigned as follows:
Engine: ORACLE Physical Name: @OraInfo
LIBNAME statement
LIBNAME statement
PROC PRINT DATA=MYORALIB.NBR_DAYS_TO_DATE_LKUP;
RUN;
LIBNAME statement
Helpful Info Automatic macro variables
&sysdbmsg displays the DBMS error messages58 %put &sysdbmsg;ORACLE: ORA-01017: invalid username/password; logon denied
&sysdbrc displays the DBMS error codes59 %put &sysdbrc;-1017
Sql pass thru query
PROC SQL;
CONNECT TO ORACLE(USER=MYUID ORAPW=MYPASSWORD PATH='@OraInfo');
SELECT * FROM CONNECTION TO ORACLE
(SELECT * FROM MYSCHEMA.NBR_DAYS_TO_DATE_LKUP);
DISCONNECT FROM ORACLE;
QUIT;
Sql pass thru query
Sql pass thru query
Execute statement execute (grant select on
MYSCHEMA.MY_TABLE to OTHERUID) by oracle;execute (execute credit(234,5000)) by oracle; execute (create unique index my_pk on
MYUID.MY_TABLE (MYFIELD) ) by oracle;Execute (drop table MYUID.MY_TABLE) by oracle;
Sql pass thru query
Automatic macro variables&sqlxmsg displays the DBMS error messages
64 %put &SQLXMSG;ORA-12560: TNS:protocol adapter error
&sqlxrc displays the DBMS error codes65 %put &SQLXRC;-12560

What you need to know
Schema = option In Microsoft Access, when connecting to Oracle tables, the
Schema name is identified as the text to the left of the period.
The best way to find out is to go to the source, your Oracle DBA
Error Messages
The service you’re referencing is not configured in your sqlnet.ora file.ERROR: ORACLE connection error: ORA-12154: TNS:could
not resolve service name.

Options
The following option statement causes information about the query that is being passed to Oracle to be printed in the SAS log, so you can see the logic being passed.
Options SASTRACE= ‘,,,d’ SASTRACELOC=SASLOG;
Alternatives
So what if I don’t have SAS/Access for Oracle?
Using ODBC drivers
Syntax for Libname statement LIBNAME MYORALIB ODBC DSN=MyOracle UID=MYUID PW=MYPASSWORD SCHEMA=MYSCHEMA;
Syntax for pass-thru SQL query PROC SQL; CONNECT TO ODBC(DSN=MyOracle UID=MYUID PW=MYPASSWORD);
SELECT * FROM CONNECTION TO ODBC (SELECT * FROM FIN1MGR.NBR_DAYS_TO_DATE_LKUP);
DISCONNECT FROM ODBC; QUIT;
Conclusion
SAS offers a variety of ways to access data that is stored in Oracle.
Work with your Oracle DBA to assistance with connection questions.
Utilize the numerous Users Group papers on the subject of methods and efficiencies accessing Oracle data.
