Vista - Urgent

Hi all,
I have created a workflow in that I used code activity through that
I am accepting the connection string and query from user. Now I want
that user fires any query suppose
select * from userid(tablename). Suppose I have a database in which in
have a table userid in which I have three fields id, name , age.
Now what i want is user fires a query and I have to store data
fields(id, name , age) and promote them by using dependency property or
dependence property regeister attached. I am not getting any idea what
type of code to write please give answer in code too.
In that case problem is that we don't know data fields like id, name
,age in above and don't know its datatype. So please give answer early
Thanks
