Description

SnowConvert will add this warning because PostgreSQL supports arrays of any built-in or user-defined base type, enum type, composite type, range type, or domain, whereas Snowflake does not. In Snowflake, each value in a semi-structured array is of type VARIANT.

Example Code

Input Code:

IN -> PostgreSQL_01.sql

CREATE TABLE sal_emp (
name            text,
pay_by_quarter  integer[],
schedule        text[][]
);

Output Code:

OUT -> PostgreSQL_01.sql

CREATE TABLE sal_emp (
name            text,
pay_by_quarter ARRAY /*** SSC-FDM-PG0016 - STRONGLY TYPED ARRAY 'INTEGER[]' TRANSFORMED TO ARRAY WITHOUT TYPE CHECKING ***/,
schedule ARRAY /*** SSC-FDM-PG0016 - STRONGLY TYPED ARRAY 'TEXT[][]' TRANSFORMED TO ARRAY WITHOUT TYPE CHECKING ***/
)
