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:

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:

SELECT

/*** MSC-ERROR - MSCEWI3116 - OPERATIONS BETWEEN INTERVALS ARE NOT SUPPORTED BY SNOWFLAKE ***/
/*INTERVAL '1-1 year' + INTERVAL '1y, 1mm' + INTERVAL '1y, 1mm'*/
null
FROM dual;

SELECT
/*** MSC-ERROR - MSCEWI3116 - OPERATIONS BETWEEN INTERVALS ARE NOT SUPPORTED BY SNOWFLAKE ***/
/*INTERVAL '1y, 1mm' + INTERVALCOLUMN*/
null
FROM PUBLIC.INTERVALTABLE;

Recommendations

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