SSC-EWI-RS0008

Date literal is not supported in Snowflake.

Severity

High

Description

This conversion issue is added since In Redshift you can apply the DELETE statement to materialized views used for streaming ingestion. In Snowflake, these views are transformed into dynamic tables, and the DELETE statement cannot be used on dynamic tables.

Code Example

Input Code:

IN -> Redshift_01.sql

CREATE MATERIALIZED VIEW mv AS
SELECT id, name, department_id FROM employees WHERE department_id = 101;

DELETE FROM mv
WHERE id = 2;

Output Code:

OUT -> Redshift_01.sql

CREATE DYNAMIC TABLE mv
--** SSC-FDM-0031 - DYNAMIC TABLE REQUIRED PARAMETERS SET BY DEFAULT **
TARGET_LAG='1 day'
WAREHOUSE=UPDATE_DUMMY_WAREHOUSE
COMMENT = '{ "origin": "sf_sc", "name": "snowconvert", "version": {  "major": 0,  "minor": 0,  "patch": "0" }, "attributes": {  "component": "redshift",  "convertedOn": "03/03/2025",  "domain": "test" }}'
AS
SELECT id, name, department_id FROM
employees
WHERE department_id = 101;


!!!RESOLVE EWI!!! /*** SSC-EWI-RS0008 - MATERIALIZED VIEW IS TRANSFORMED INTO A DYNAMIC TABLE, AND THE DELETE STATEMENT CANNOT BE USED ON DYNAMIC TABLES. ***/!!!
DELETE FROM
mv
WHERE id = 2;

Recommendations

• Because dynamic tables cannot be directly deleted from, you can achieve the same result by replacing the dynamic table definition.
