Severity

Medium

Some parts of the output code are omitted for clarity reasons.

Description

This issue happens when there is an OUTER JOIN with the (+) operator inside a BETWEEN clause that cannot be executed in Snowflake. This generally happens when multiple tables are used in the interval of the BETWEEN clause.

Example Code

Input Code Oracle:

IN -> Oracle_01.sql

SELECT
*
FROM 
hr.countries c, hr.regions r,  hr.locations l WHERE 
l.location_id  BETWEEN r.region_id(+) AND c.region_id(+);

Output Code:

OUT -> Oracle_01.sql

SELECT
*
FROM
hr.countries c,
hr.regions r,
hr.locations l WHERE
!!!RESOLVE EWI!!! /*** SSC-EWI-OR0090 - INVALID NON-ANSI OUTER JOIN BETWEEN PREDICATE CASE FOR SNOWFLAKE. ***/!!!
l.location_id  BETWEEN r.region_id(+) AND c.region_id(+);

Recommendations

• Manually change the Outer Join to ANSI syntax.
