Hi,
I am real new to databases and hoping someone can help.
Main-table is a huge spreadsheet that I imported into Access
Site-table has a bunch of addresses pulled from Main-table, quite a few
overlap in some areas and none of the fields are unique except the
AddressKey which I created after pulling data from the Main-table. Why some
fields are not unique I won't get into.
what I currently have.....
UPDATE [Main-table]
INNER JOIN [Main-table].[AddressLine01]=[Sites-table].[AddressLine01]
SET [Main-table].Addressfkey = [Sites-table].[AddressKey];
I have now created a colum in the Main-table called Addressfkey which I
would like to correlate to the AddressKey in Sites-table. Since none of the
fields are unique in Sites-table, is there a way to modify the following so
that I can INNER JOIN based on more than one field? Currently I use
[Main-table].[AddressLine01]=[Sites-table].[AddressLine01] but this doesnt
get specific enough, for example , how could I work in the equivalent of
INNER JOIN [Sites-table] ON
[Main-table].[AddressLine02]=[Sites-table].[AddressLine02]
so that if two fields in the inner join matches, then it performs the SET
Or, is there a different batch of commands altogether
Thanks....Steve 1 1542
Steve,
Yes, in short. JOINS are a big subject in SQL. You can do a lot that isn't
directly supported through the QBE grid in Access. My favorite IT book
publisher, O'Reilly, publishes an SQL pocket guide that documents lots of
neat tricks and it's under $20.00. I don't work for them or get compensated
for plugging a book in any way. I just like the book and think you would
benefit from buying it.

Oh I have a nasty query which runs incredibly slowly. I am running MySQL
4.0.20-standard. Thus, in trying to expedite the query, I am trying to set
indexes in my tables.
My query requires four inner joins, as follows :
SELECT DISTINCT
upcards.id,statuskey.status,upcards.firstname,upcards.lastname,originkey.ori
gin,associatekey.username,associatekey2.username,upcards.deleted

Hi,
I have the following sql statement. I originally had the statement
with two INNER JOINS but in some situations was getting an error so
changed the last INNER JOIN to a LEFT OUTER JOIN (as is seem below).
This seemed to work but i am unsure why and would like to know in case
it falls over again. Why did the two INNER JOINS not work, and am I
correct to use the LEFT OUTER JOIN in this context.
As you can see the table 'tblStaff1_2'...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

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,...
