Description
En the source language, the removal of a comment is accomplished using the term "NULL." However, in Snowflake, a comparable method for eliminating a comment involves assigning the value of an empty string '' to achieve the same effect. This approach ensures that the comment is effectively assigned to empty string with a similar effect.
Code Example
Input Code:
COMMENT ON TABLE mytable IS NULL;Output Code:
COMMENT ON TABLE mytable IS '' /*** MSC-WARNING - MSC-PG0021 - NULL IS CONVERTED TO '' AND MAY HAVE A DIFFERENT BEHAVIOR IN SNOWFLAKE. ***/ ;Recommendations
