Description

Date, time, and timestamp literals supported by Amazon Redshift.(Redshift SQL Language reference Date, Time, Timestamp Literals).

Sample Source Patterns

Input Code:

Redshift

IN -> Redshift_01.sql

--invalid
SELECT
DATEADD(month, 1, 'January 8, 1999'),
DATEADD(month, 1, '2000-Jan-31'),
DATEADD(month, 1, 'Jan-31-2000'),
DATEADD(month, 1, '20000215'),
DATEADD(month, 1, '080215'),
DATEADD(month, 1, '2008.366'),
DATEADD(month, 1, 'now');

--valid
SELECT
DATEADD(month, 1, '1999-01-08'),
DATEADD(month, 1, '1/8/1999'),
DATEADD(month, 1, '01/02/00'),
DATEADD(month, 1, '31-Jan-2000');

Output Code:

Snowflake

OUT -> Redshift_01.sql

SELECT
 DATEADD(month, 1, '1999-01-08'),
 DATEADD(month, 1, '1/8/1999'),
 DATEADD(month, 1, '01/02/00'),
