SSC-EWI-0045

Column Name is Snowflake Reserved Keyword.

Severity

Medium

Description

In some cases, column names that are valid in the source language may conflict with Snowflake's reserved keywords. These conflicts arise because Snowflake reserves a set of keywords that cannot be used directly as column names without special handling. For details, refer to Snowflake's official documentation on reserved and limited keywords.

Code example

Input

IN -> Oracle_01.sql

CREATE TABLE T1
(
    LOCALTIME VARCHAR,
    CURRENT_USER VARCHAR
);

Output

OUT -> Oracle_01.sql

CREATE OR REPLACE TABLE T1
    (
    !!!RESOLVE EWI!!! /*** SSC-EWI-0045 - COLUMN NAME 'LOCALTIME' IS A SNOWFLAKE RESERVED KEYWORD ***/!!!
    "LOCALTIME" VARCHAR,
    !!!RESOLVE EWI!!! /*** SSC-EWI-0045 - COLUMN NAME 'CURRENT_USER' IS A SNOWFLAKE RESERVED KEYWORD ***/!!!
    "CURRENT_USER" VARCHAR
    )
    COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
    ;
