On Dec 1st, 2019, Snowflake will turn on strict string-to-date conversion for all Keboola Connection projects.
By introducing this change, Snowflake wants to address issues such as invalid date strings rolling over. For example, 07-32 (July 32nd) has been interpreted as August 1st. Rollover will no longer be supported for dates, times, or timestamps.
A full description of affected cases and tips on what to do are provided in the Snowflake 3.45 Release Notes.
We have a list of affected queries in the Keboola Connection projects ready and will be contacting all users that may be affected by this change. You'll have plenty of time to check everything and fix any potential issue.
Thanks a lot for your cooperation.
