Re: Error in Adding All Tables

Yes, i'm working with VS 2008 with QT framework working on a
application with i don't know couple hundred thousand lines of code.

Been using VS sense 1997  how about you???

One of your big problems is your using the Automatic Class builder. 
Its sucks and is what is causing your problem as it creates code that
don't work.

Case in point the SQL code is wrong. 

In this case the Select statement being created is trying to join two
tables together that have the same column name

Select * from mytable, othertable where ctid = ctid
this command will create the error you have

now to avoid the error it should look like this
Select * from mytable, othertable where mytable.ctid = othertable.ctid

Now Postgresql knows what you want it to do.  Before the Postgresql has
two columns with the same name and does not understand how to join the
two tables

Find the the code where the Select statement is change the Joining
argument

        you mean you are trying some kind of table joining correct???

example

Select * from mytable, othertable where ctid = ctid ???

Please post the SQL statement you are using to communicate with
thedatabase. 
The select insert update commands.   If i could see what you are doingi
would have solved your problem 3 emails ago.

just post the C++ code that has the problem

Without looking at the sql statement you are using its kinda
hardtoknowwhat the problem is

but ambiguous column means the Postgresql can't figure o ut
whatyouwantto do as the column shows up twice in a command.
