sql语法-表A如何由表B对应相同的值做转换

请教表A如何由表B对应相同的值做转换：
表A：

A1 (1) (2) (3) (1,2),(2,3) (1,2,3)
B1 (3) (6) (8) (3,6),(6,8) (3,6,8)
C1 (3) (6) (3,6)
…
表B：
(1) a
(2) b
(3) c
(6) d
(8) e
(1,2) f
(2,3) g
(3,6) h
(6,8) i
(1,2,3) j
(3,6,8) k
…
结果：

A1 a b c f,g j
B1 c d e h,i k
C1 c d h

update a set a.I1=b.No from @A a join @B b on a.I1=b.I
update a set a.I2=b.No from @A a join @B b on a.I2=b.I
update a set a.I3=b.No from @A a join @B b on a.I3=b.I

-- I4是多个()的组合，这样处理
while exists (select 1 from @A a,@B b where charindex(b.I,a.I4)> 0)
update a set a.I4=replace(I4,b.I,b.No) from @A a join @B b on charindex(b.I,a.I4)> 0

-- I5也是？I4替换成I5
while exists (select 1 from @A a,@B b where charindex(b.I,a.I5)> 0)
update a set a.I5=replace(I5,b.I,b.No) from @A a join @B b on charindex(b.I,a.I5)> 0

select * from @A
