I have oracle8i database. I built DBGrid which is bound to
ORADC. The recordsource of the ORADC is the join of two tables. I am not sure if inner join is allowed for Oracle, and i use, for example
select * from dept, emp where emp.deptno=dept.deptno

Now I want to use DBGrid to show all the fields.
I always got the error(like ambiguous column) even i bind the DBGrid datafield as dept.deptno

Please help me

Rather than that it would be better (and actually quicker) to explicitly specify your select list:

Select Dept.Deptno As Dept_Number,Emp.Deptno As Emp_Dept ....
