SQL compilation error: Format argument for function 'TO_TIMESTAMP_TZ' needs to be a string

Question

我正在从 snowflake 中的内部阶段文件中查询数据，如下所示 - 我收到以下错误： SQL 编译错误：函数 'TO_TIMESTAMP_TZ' 的格式参数需要是字符串

知道这里可能出了什么问题吗？谢谢

尝试

select to_timestamp_tz(CURRENT_TIMESTAMP::string)

第二个参数是格式（varchar 类型），你传递的是数字。

select to_timestamp_tz('04/05/2013 01:02:03', 'mm/dd/yyyy hh24:mi:ss');
