Answer 1

我想你會發現這個用戶定義函數來分割字符串有所幫助：

Answer 2

declare @T table 
(
    Value varchar(15) 
) 

insert into @T values 
('90-PMR-450'), 
('90-PMRA-340') 

select stuff(Value, 1, 1+len(Value)-charindex('-', reverse(Value)), '') 
from @t 

Answer 3

DECLARE @x TABLE(v VARCHAR(32)); 

INSERT @x SELECT '90-PMR-450' 
UNION ALL SELECT '90-PMRA-340'; 

SELECT Part3 = PARSENAME(REPLACE(v, '-', '.'), 1) FROM @x;
