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

Description

This error is added when there is an arithmetical operation whose operands are only intervals, this kind of operation is not supported by Snowflake.

Example Code

Input Code:

IN -> Oracle_01.sql

SELECT INTERVAL '1-1' YEAR(2) TO MONTH + INTERVAL '1-1' YEAR(2) + INTERVAL '1-1' YEAR(2) TO MONTH FROM dual;

SELECT INTERVALCOLUMN + INTERVAL '1-1' YEAR(2) TO MONTH FROM INTERVALTABLE;

Output Code:

OUT -> Oracle_01.sql

SELECT
--INTERVAL '1-1 year' + INTERVAL '1y, 1mm' + INTERVAL '1y, 1mm'
!!!RESOLVE EWI!!! /*** SSC-EWI-OR0116 - OPERATIONS BETWEEN INTERVALS ARE NOT SUPPORTED BY SNOWFLAKE ***/!!!
null
FROM dual;


SELECT
!!!RESOLVE EWI!!! /*** SSC-EWI-OR0036 - TYPES RESOLUTION ISSUES, ARITHMETIC OPERATION '+' MAY NOT BEHAVE CORRECTLY BETWEEN Unknown AND Interval ***/!!! INTERVALCOLUMN + INTERVAL '1y, 1mm'
FROM
INTERVALTABLE;

Recommendations

• Depending on where the operation is located, it could be relocated and made valid by adding dates or timestamps.
