当我使用以下公式时 convert_timezone('EST', 'UTC', "Time"::timestamp_ntz) as Time_UTC ,convert_timezone('EST', "LOCAL_TIMEZONE","Time"::timestamp_ntz) as Time_LOCAL 对于某些行,数据是正确的,而对于某些行,数据是不正确的。有人能告诉我为什么会这样吗? ? 浏览28提问于2020-11...
在Snowflake中,可以通过修改默认时间戳列的时区来更改时区设置。默认情况下,Snowflake使用UTC(协调世界时)作为时间戳列的时区。 要更改默认时间戳列的时区,可以按照以下步骤进行操作:...
Converts an input expression into the corresponding timestamp:TO_TIMESTAMP_LTZ (timestamp with local time zone) TO_TIMESTAMP_NTZ (timestamp with no time zone) TO_TIMESTAMP_TZ (timestamp with time zone)Note TO_TIMESTAMP maps to one of the other timestamp functions, based on the TIMESTAMP...
