store array or vector in ms sql server 2005

Anyone knows how to store array or vector in ms sql server 2005? There is way to store array in oracle db but I don't know about sql server.

eg:

st_id [1234]
st_mk [(12),(34),(67),(45)]

st_id [3456]
st_mk [(12),(34)]开发者_JAVA百科

Like above st_mk (the vector size) is not same.

Please help me...!!

In a separate child table?

create table Vector(st_id int primary key)

create table VectorElement
(
    st_id int references Vector(st_id),
    element int
)

create index IX_VectorElement_st_id on VectorElement(st_id)

insert Vector
values(1234)

insert VectorElement
select 1234, 12 union all
select 1234, 34 union all
select 1234, 67 union all
select 1234, 45

Another option to store it as a string (varchar), but this is less efficient and you would need to parse it.

Another option is to use XML type column.
