Other SQL operators

SQL supports miscellaneous operators that perform various operations.

OperatorMeaning
||Concatenate strings
AT TIME ZONEApply a time zone offset

||

The || operator concatenates two string operands into a single string.

SELECT 'Hello' || ' world' AS "Concatenated"
Concatenated
Hello world

AT TIME ZONE

The AT TIME ZONE operator takes the timestamp in the left operand and returns an equivalent timestamp with the updated time and offset of the time zone specified in the right operand. If no time zone is included in the input timestamp’s Arrow data type, the operator assumes the time is in the time zone specified. Time zone offsets are provided by the operating system time zone database.

SELECT time AT TIME ZONE 'America/Los_Angeles' FROM home

Convert a UTC timestamp to a specified timezone

Add a time zone offset to a timestamp without a specified timezone
