Selecting by column number, MS SQL 2000

Ok, so I need to select data from a column by its number. something like:

SELECT COLUMN_NAME(@int_col_num) FROM MY_TABLE WHERE CONDITION = 'whatever'

The problem being that there is no function called COLUMN_NAME, the closest thing I could find is COL_NAME but for some reason that won't work. when I do something like:

SELECT COL_NAME(@table_id, @int) FROM TABLE WHERE CONDITION = 'whatever'

the only thing I get back is the output of COL_NAME(@table_id, @int) almost like it ignored the word "FROM" and everything behind it.

Is there any way I can select data by the column number and not by the column name??

My DB system is MS SQL Server 2000.

Yes.

you have to combine with object id

here is the example


create table X123 (id int, name char(10))
insert into x123 select 1,'asa'
insert into x123 select 2,'pia'
insert into x123 select 3,'pin'
insert into x123 select 4,'ahs'
insert into x123 select 5,'bit'

--to get the column name
select col_name(Object_id('x123') ,1)
select col_name(Object_id('x123') ,2)

for getting values from such columns


declare @query varchar(1000)
set @query = 'select '+col_name(Object_id('x123') ,1)+' from x123'
exec (@query)

Thats great the EXEC('some query') works just fine, but how do I get the results of that query back into a variable? For example I can:

DECLARE @var varchar(50)
EXEC('SELECT @col_name FROM TABLE WHERE CONDITION = whatever')

but It won't let me do something like
SELECT @var2 = EXEC(@some_query)
or
SELECT @var2 = Select top 1* from (EXEC (@some_query))

I need to get the results of that query back into a program variable @variable. How do I do that?
