MSCEWI1061
Column does not come from a Non-Ansi Outer Join Expression
This is a deprecated version of the SnowConvert documentation, please visit the official site HERE.
This EWI will be deprecated in the future.
Severity
Low
Description
Snowflake does not support using Non-Ansi Outer Join syntax in a column from a table that was not previously used in a Non-Ansi outer join expression.
Example Code
Input Code (Oracle):
SELECT * FROM
EMPLOYEE e, PRODUCT p WHERE
e.id = p.eid AND
e.name(+) IN ('US', 'CANADA');
Output Code:
SELECT *
/*** MSC-WARNING - MSCEWI3081 - SNOWFLAKE NON-ANSI OUTER JOIN SYNTAX HAS SOME FUNCTIONAL DIFFERENCES COMPARED TO ORACLE. IT COULD CAUSE COMPILATION ERRORS ***/
FROM PUBLIC.EMPLOYEE e, PUBLIC.PRODUCT p WHERE
e.id = p.eid AND
e.name(+) IN ('US', 'CANADA') /*** MSC-WARNING - MSCEWI1061 - COLUMN DOES NOT COME FROM A NON-ANSI OUTER JOIN EXPRESSION. IT MAY CAUSE A COMPILATION ERROR ***/;
Recommendations
Rewrite the statement using ANSI Outer Join syntax.
