Hi David.
This gives ...
ERROR: column src.key does not exist
LINE 8: WHERE mt.key = src.key;
^
HINT: Perhaps you meant to reference the column "src.key".
********** Error **********
Funny how it is suggesting the exact thing that it says is the problem. In reality, I will have the key value in a variable so I can do ...
WHERE mytest.key = key_variable;
There are a few techniques you are using here that I am not familiar with. I will study-up and get back to you later.
