Hi,
I have two tables.
Table 1 (Date, Total)
Table 2 (Date, Total)
I'm trying to find a select statement which will give me all the dates
from Table 1 and Table 2 in a column along with Table1.Total and
Table2.Total.
ie.
Dates, Table1.Total, Table2.Total
I'm told that I would need a FULL OUTER JOIN to be able to do this but
according to the MySQL reference, FULL OUTER JOIN is not supported? How
would I be able to achieve the required result? 2 1325

Are these the only 2 fields in each table?? not very descriptive if you
ask me...
Is DATE unique in each table (only 1 entry per day(date))?
if so,
then
select c.date,sum(tota l) from (
select a.date as date,a.total as total from table1 a
union all
select b.date as date,b.total as total from table2 b
) c group by date order by c.date;
if you need all date/total values:
select a.date,a.total from table1 a
union all
select b.date,b.total from table2 b;
try each to see if you like one or the other...

Hi Callista
Try
select date,sum(total1 ) as total1,sum(tota l2) as total2
from (
select date,total as total1,null as total2
from Table1
union
select date,null as total1,total as total2
from Table2) c
group by date
That should result in something like
date total1 total2
aaa bbb ccc
xxx yyy zzz
regardless of whether date is unique
You can use '0 as total1' and '0 as total2' if you prefer to return '0' for
dates without entries as opposed to 'null' - this may make it easier if you
want a fourth column such as 'sum(total1+tot al2) as total'
Hope that is what you need.

Hi All,
While in the process of building my table (40 or so Insert statments)
can I then query ("select * from @Table_variable") and use the results
up to theat point for another insert into @Table_varible? If you look
for stepID -15 I have commented that section out due to it not
retuning the correct values.
Thank you in advance

I can't come up with a query that works. Can anyone help?
Conceptually the relationships are easy to describe. I have

and a linking table between the two because books often
have more than one author (OA_Link). This situation is
simple and common. A query to list each title and all
the authors associated with that title looks like this:

I wish to build a table based on values from another table.
I need to populate a table between two dates from another table. Using
the START_DT and END_DT, create records between those dates.
I need a new column that is the days between the date and the MID_DT
The data I wish to end with would look something like this:
PERIOD DATE DAY_NO
200602 2005-07-06 -89
200602 2005-07-07 -88

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,...
