I have 2 tables with different versions in access. Both are same but the latest version obviously has some new records and some deleted records from the previous version. How would I compare the new table with the old one? I have a common field called MFI_ID having the value AT00100, AT10000 etc, in both the tables. I need to put the query and find out the new records in the new table as well as deleted records from the old table. The comparison is as follows (example):
Sheet.MFI_ID Sheet1.MFI_ID
AT00100 AT00100
AT10000 AT10000
AT12000 AT12000
AT14000 AT14000
AT14200 AT14200
AT14900 AT14900
AT15000 AT15000
AT16000 AT16000
AT17000 AT17000
AT18100 AT18100
AT18120 AT18120
CY151012 AT19230
CY151032 AT34000

A left join where Sheet1 is null will give you deleted records.
A right join where Sheet is null will give you new records.
Thanks again. Is there anyway these two could be used together in a query?

No, you can't combine the two joins in that fashion. You can create two queries and then combine them in another query though. When you run the third query, it'll automatically run the first two.
Thanks for your help again. I really appreciate it.

I have a giant (couple thousand rows) HTML table.
Im trying to modify some of the cells innerHTML and/or innerText, but
it is taking a VERY long time to do so.
I believe that the problem is not with executing the code, but rather
with the browser reparsing the page, or the table, or something.

Hi All,
I am trying to unload some 10 db2 tables from 2 environments and
then do a file comparison between them. Since SYSPUNCH card contains
all the information like field names, column length, position etc, i
have written a Rexx program that reads the SYSPUNCH and does a field
level comparison with the help of length and position fields. Same
way, repeating for the rest of unloaded tables.
Now, my problem is SYSPUNCH card doesn't...

I would be grateful if someone had a minute or two to review my hash
table implementation. It's not yet commented but hopefully it's short
and idiomatic enough to be readable. Some of the code (i.e. the
get_hash function) is borrowed from various snippets I found on the
net. Thee free function could probably need some love. I have been
thinking about having a second linked list of all entries so that the
cost of freeing is in proportion to...

A quick sanity check, and I think I am correct, but just to make
sure: if you have a bunch of objects that are very much like one
another you can uniquely track them simply by using an ArrayList or
Array, correct? An example: create the object, create an array, the
stuff the object into the array. Later on, assume the object is
mutable, the object changes, but you can find it, if you have enough
state information to uniquely identify...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
