Hi freinds,
i wanted to add my all tables once in MFC application,

i have a databank,which has 11 tables and i want to add them all togather.

 After Adding all tables, it shows me always this errors by debugging.


ERROR: column reference "ctid" is ambiguous;
Error while executing the query

This means you did this:

SELECT ctid,ctid from table1, table2

But it doesn't know which ctid belongs to which table. You need to use aliases or dotted notation.
