Temporary and transient tables in Snowflake do not have a Fail-safe period. Once the session ends or the tables are dropped, the data is purged and not recoverable1.
Reference: https://docs.snowflake.com/en/user-guide/tables-temp-transient.html

In Snowflake, to extract a specific value from a VARIANT column, you use the column name followed by a colon and then the key. The keys are case-sensitive. Therefore, to extract the employee's name from the
"Data" column, the correct syntax is data:employee.name.
