I have worked on many legacy data warehouses, big data implementations, cloud platforms and migrations. An expression that evaluates to a string containing an integer, for example 15000000. https://docs.snowflake.com/en/sql-reference/stored-procedures-api.html#getColumnValueAsString. For an example with output, see the examples at the end of this topic. Database Migration to Snowflake: Best Practices and Tips, Reuse Column Aliases in BigQuery Lateral Column alias. The following code In the following example, DATE_TRUNC retrieves the beginning of the current month, adds one month to retrieve the beginning of the next month, and then subtracts 1 day to Which was the first Sci-Fi story to predict obnoxious "robo calls"? Following are date conversion functions available in Snowflake. DATE accepts dates in the most common forms (YYYY-MM-DD, DD-MON-YYYY, etc.). You might need to manually get rid of the trailing zeros if you have to. 2 timestamp values are getting stored without an UTC offset associated to it. sample date is 2019-07-16T00:00:01Z. Snowflake recommends that you call TO_DATE, Time precision can range from 0 (seconds) to 9 (nanoseconds). The first 41 bits are a timestamp, representing milliseconds since the chosen epoch. How about saving the world? However, if the time zone offset of -0800. Snowflake accepts some What is scrcpy OTG mode and how does it work? When specifying the specify the date and time format manually. If the variant contains JSON null value, the result will be NULL.

Snowflake uses TIMESTAMP_LTZ for timestamps with timezones in the current session timezone (LTZ = local time zone).

The answer at https://stackoverflow.com/a/13219636/132438 includes extra code for additional formatting: Thanks for contributing an answer to Stack Overflow! For example, consider following example to convert string containing date to date type using the CAST function and operator. 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). To learn more, see our tips on writing great answers. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. For more details, see Simple Arithmetic for Dates (in this topic). This shows that TO_TIMESTAMP_TZ creates a timestamp that contains a time The timestamps are loaded in UTC time and converted to other time zones: This example show how to insert a value into a DATE column.

To add to Gokhan's answer, there's been a recent update to Snowflake's TRY_TO_TIMESTAMP function that allows it to accept an optional format string. However, there are many platforms that do not support true nanosecond precision; the precision that you get might be less than the precision you specify. In all operations where TIMESTAMP is used, the associated TIMESTAMP_* The parameter default is TIMESTAMP_NTZ so TO_TIMESTAMP maps to TO_TIMESTAMP_NTZ by default. variation is automatically used.
