Description

Snowflake does not guarantee generating sequence numbers without gaps. The generated numbers consistently increase in value (or decrease in value if the step size is negative) but are not necessarily contiguous.

Code Example

Input Code:

PostgreSQL

IN -> PostgreSQL_01.sql

SELECT nextval('seq1');

Output Code:

Snowflake

OUT -> PostgreSQL_01.sql

SELECT seq1.nextval /*** SSC-FDM-PG0009 - THE SEQUENCE NEXTVAL PROPERTY SNOWFLAKE DOES NOT GUARANTEE GENERATING SEQUENCE NUMBERS WITHOUT GAPS. ***/;
