Hi,
I was just helping a coworker optimize a query. He had two versions:
one which used UNION for each value for which he was tallying results
and another query which used GROUP BY. Here is an aproximation of what
they were:
Query #1:
---------
SELECT 12 AS ,

Example, suppose you have these 2 tables
(NOTE: My example is totally different, but I'm simply trying to setup
the a simpler version, so excuse the bad design; not the point here)
CarsSold {
CarsSoldID int (primary key)
MonthID int
DealershipID int

Using A2K. In my table I have the field "Grant" which can have a
value or be null. I have a query that counts the number of records
and has a Where clause on the Grant field. The query won't work when
Grant is null. What's the proper syntax for getting it to work when
Grant is null?
Here's my Where criteria:

Hi,
I think this is quite a simple one:
I have a ComboBox, where the source is a stored query. When I click the
drop-down arrow on the Box, it takes awhile. I want to run this query
in the background when the form opens, so that when I click the
dropdown, it is ready.
How?

This is probably a general SQL question but since I am dealing w/ DB2 I figured I would ask here.
I have a table with customer transaction information. The primary keys are cust_id and date (transaction data that is). The trasactions can be later modified and this causes for the field TRANS_SQ to auto increment. What I want to do is query for the rows that pertain to a particular transaction but hold the highest TRANS_SQ value.
Below is a...

Hi. I have this Combobox name 'Origin' that contains all states and
countries. I would like to create two Radio buttons (State and
Country) that when you select State, the combobox will query only the
states and vice versa for country. I've create two columns in the
Origin table (OriginState and OriginCountry) and set the data type to
'bit' to differentiate the two. How would I query the combobox when a
radiobutton is selected? Thanks.

Overview:
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,...

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
