SQL Statement with min function

hi,

i have 2 tables. one contains OBJ_NAME and TRKORR and the other contains AS4DATE and TRKORR.

In the first table are a lot of objects. One object is also named more than once.

That means:

1 Object has n TRKORR has 1 DATE. (For all the diffrents objects)

I need all the Objects with their MIN DATE.

At the end i should have every object once with it's min date.

If i didn't explain it good enough please ask me again.

Any Ideas for the Select Statement?

Regards,

Jan
