When an INTEGER value is cast directly to TIMESTAMP_NTZ, the integer is treated as the number of seconds since the beginning of the Linux epoch, and the local time zone is not taken into account. However, if the INTEGER value is stored inside a VARIANT value, for example as shown below...
"DATE" AS timestamp)) ORDER BY date_trunc("day", CAST("PRODUCT_ANALYTICS"."PAGES_UNION"."DATE" AS timestamp)) DESC; If I replace current_timestamp() with current_date() I get exact same results, except query returns in a matter of milliseconds next time because results are cached. ...

The service compares the Unix Epoch with the given starting timestamp as part of the process in generating a unique Snowflake. As a result, Snowflakes can be generated for up to 69 years using any given starting timestamp. In most cases, you should set this value to the current date usin...
在scan时可以下推投影或者cast等运算符。并且通过Bloom filte来快速过滤不需要的文件优化执行路径上的剪枝优化。 对于一些日期类型的数据,由于没有定义保存精度等问题,Snowflake会使用单独的列转换的结果以及原始的字符串,来应对类型转换时精度损失的问题以及转换后可以用来做一些剪枝的操作。 对于VARIANT类型以及关系型的...
Datameer has a rich catalog with easy-to-use functions; this includes the in-built “TODATE” function that can extract the date from a timestamp and output the correct date format in a matter of seconds.2. CONVERT or CAST functionIn SQL Server 2008 and above, we can either use the ...
In SQL Server, theDATETIMEdatatype is used to represent both date and time values. In Snowflake, the equivalent datatype isTIMESTAMP, which also represents both date and time values. Here’s an example: CAST(concat(year(drop_date), format(month(drop_date), ’00’), format(day(drop_dat...
