I don't want seconds, milliseconds, or timezone included in my result. As the resulting integer value is too large, it will result in an 'Invalid date' value (since the timestamp-micros is counted in microseconds, it would then become too large in seconds - as TIMESTAMP_NTZ is represented in seconds). Generates either a version 4 (random) or version 5 (named) RFC 4122-compliant universally unique identifier (UUID) as a formatted string. See the example below. Do you know what could be the issue here? Here is my code - Select to_timestamp_tz(EFFECTIVE_DATE) from Table1 We have a timestamp column that as values as below, Tried below query but didnt work. The AT or BEFORE clause is used for Snowflake Time Travel. TIMESTAMP_TZ_FROM_PARTS: Construct a new TIMESTAMP_TZ using all the components from the source TIMESTAMP_NTZ and provide the timezone as the last parameter. e. The semantics of CAST are the same as the semantics of the corresponding to datatype conversion functions. This is called implicit casting or coercion. The function returns a value of type DATE or NULL: If the type of the value in the variant_expr argument is DATE, the function returns a value of type DATE. I am not sure why snowflake is setting the year as 1970 and month as August. For timestamp_expr, the timestamp to convert to a time. If the type of the value in the variant_expr argument doesn’t match the type of the output value, the function returns NULL.
