Extract Left and Right Part from a string having a format of xxxx/yyyy where x=>alphabets, y=>numbers in SQL

Let's say we have a table as

Declare @t Table(Code varchar(20) )

insert into @t values('AAAA/00001')
insert into @t values('BBB/00010')
insert into @t values('CCC/00002')
insert into @t values('ZZZ/00100')

We need to Extract Left and Right Part from Code

The below code will do so

Declare @t Table(Code varchar(20) )

insert into @t values('AAAA/00001')
insert into @t values('BBB/00010')
insert into @t values('CCC/00002')
insert into @t values('ZZZ/00100')

Select

	,RightPart=SUBSTRING(Code,CHARINDEX('/',Code)+1,LEN(Code))	
From @t x
