Update Statement with Inner Join

update with inner join

I am writing a code that takes four records through loop then copy them to temporary table calculate average over there of the four records then store that avg value in a variable. My curiosity is just that if its possible for that to work from Data Source window, I think it is also possible for it to work using the hard coding. You can then configure the columns via sub routines if necessary. Yours is starting if you are a worm in the apple , and my workday is ending in a couple of hours.

But I still received the same error. What i want to do is that there is table which has age and zip code. Except the last one, of course. How odd that I would stumble across this.

This table however, has one column with usernames, emails and account numbers mixed. A value of zero 0 means the table is dropped and created again. Yea but not with a joined table.
