How can I translate IANA time zone into an integer value in a SQL query?

edit

It is not possible to directly translate IANA time zone into an integer value in a SQL query as IANA time zones are represented by strings that do not correspond to a numeric system. However, you can use a lookup table that maps each IANA time zone to a unique integer value that can be used in your SQL query. Here is an example of a lookup table:

| IANA Time Zone | Integer Value | | :------------ | :------------ | | America/NewYork | 1 | | America/Chicago | 2 | | America/LosAngeles | 3 | | Europe/London | 4 | | Europe/Paris | 5 |

You can then join your main table with this lookup table on the IANA time zone column to get the corresponding integer value. For example:

SELECT t.*, l.integer_value
FROM my_table t
JOIN lookup_table l ON t.iana_time_zone = l.iana_time_zone

This will return all columns from the main table as well as the corresponding integer value from the lookup table for each IANA time zone.
