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

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.
