I have the following table structure.
group1 group2 group1_result group2_result
'One' 'Two' 3 2
'One' 'Two' 3 1
'One' 'Two' 2 5
'One' 'Two' 4 1
'One' 'Two' 0 5
I need to sum up the number of times 'One' is greater than 'Two', and
vice-versa. For example, the result I would like to achieve is as
follows.
group1 group2 group1_total group2_total
'One' 'Two' 3 2
I'm using the following SQL statement, but I get 5 rows returned,
giving me a '1' or '0' for each row.
select group1, group2
,sum(CASE WHEN group1_result > group2_result THEN 1 ELSE 0 END)
,sum(CASE WHEN group2_result > group12_result THEN 1 ELSE 0 END)
FROM table1
GROUP BY group1, group2
Any help would be greatly appreciated. 1 4827
The query you posted gives the result you say you want!
CREATE TABLE Table1 (group1 CHAR(3) NOT NULL, group2 CHAR(3) NOT NULL,
group1_result INTEGER NOT NULL, group2_result INTEGER NOT NULL /*, PRIMARY
KEY ??? */)
INSERT INTO Table1 VALUES ('One', 'Two', 3,2)
INSERT INTO Table1 VALUES ('One', 'Two', 3,1)
INSERT INTO Table1 VALUES ('One', 'Two', 2,5)
INSERT INTO Table1 VALUES ('One', 'Two', 4,1)
INSERT INTO Table1 VALUES ('One', 'Two', 0,5)
SELECT group1, group2,
SUM(CASE WHEN group1_result > group2_result THEN 1 ELSE 0 END),
SUM(CASE WHEN group2_result > group1_result THEN 1 ELSE 0 END)
FROM Table1
GROUP BY group1, group2
What is the primary key of Table1? Did you leave out some relevant
column(s)?

This is still for the db for the recreational tree climbing business. I
thought I'd solved the problem of clients often being part of the same
household, with a tblHouseholds, with Household as a FK in the Persons
table. The main reason for a Households table is to give an appropriate
mailing name for the household address, e.g. "The Brown Family" or "Jim &
Jean Smith."
This looks good to me till I consider when and how the household...

I have a problem with the following code, which leaves an instance of

By a process of elimination I have got it down to the fact that
something in the DoCmd.Transfer Spreadsheet line is holding on to an
Excel reference somewhere - can anybody assist (if I comment this line
out, the instance is released, and not visible in Task Manager).

Hi all,
I am having a problem appending data to an existing table. I have two

records are selected from T2, and there doesn't seem to be a pattern

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.
Here is my compilation command:

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,...
