CONNECT to oracle vs Libname SQL Joins (+)

StaticFX — Thu, 26 Oct 2017 17:07:10 GMT

Hi! I have a question about SQL joins using (+)

If I run a query using a connection to Oracle...

PROC SQL;

CONNECT TO ORACLE (USER='xxxxx' PASSWORD=xxxx PATH etc);

CREATE TABLE QUERY2 AS

SELECT * FROM CONNECTION TO ORACLE

(SELECT F1,F2,F3 FROM XXX WHERE A=B AND C=D(+))

it works fine

but when I use a LIBNAME to set up the connection and just use a PROC SQL;

it errors on the (+)

DO I have to do the LEFT OUTER JOIN? (Hope not.. the actual query is enormous lol)

Thanks!!

(+) is not valid SAS syntax, so yes, you need to rewrite the query in SAS SQL not Oracle SQL.

I am not sure I understand the question. Are you asking if you can ORACLE specific SQL enhancements in SAS PROC SQL code?

If so then the answer is no.

PROC SQL uses ANSI SQL 92 standard syntax, plus some SAS specific enhancements.

Why not just leave the query in ORACLE code?

libname mydata oracle ..... ;
proc sql ;
connect using mydata;
create table want as select * from connection to mydata
( ... oracle query ...)
;
quit;

Hi Tom i cant get this to work?

LIBNAME CAT ORACLE SCHEMA=CAT USER='xxxxxxx' PASSWORD='xxxxxx' PATH='@xxxx';

PROC SQL;

CONNECT USING CAT; <<< Error (connect in red)

wait... SAS EG flags that as RED/error but it works... cool 🙂

The EDITOR is not SAS.
