Answer 1

如果這僅僅是一個varchar列，那麼這可以工作：

DECLARE @t TABLE(TimeZone NVARCHAR(max)) 

INSERT INTO @t VALUES 
('(UTC-12:00) International Date Line West'), 
('(UTC-08:00) Baja California'), 
('(UTC+05:30) Chennai, Kolkata, Mumbai, New Delhi'), 
('(UTC+08:00) Kuala Lumpur, Singapore') 


SELECT TimeZone, SUBSTRING(timezone, 5, 6) AS Time FROM @t 

輸出：

TimeZone           Time 
(UTC-12:00) International Date Line West   -12:00 
(UTC-08:00) Baja California      -08:00 
(UTC+05:30) Chennai, Kolkata, Mumbai, New Delhi +05:30 
(UTC+08:00) Kuala Lumpur, Singapore    +08:00
