I have a set of data coming in from a text file that looks like:
Date ID Value
01/01/2005 1 Value1
01/01/2005 2 Value2
01/01/2005 3 Value3
01/01/2005 4 Value4
01/01/2005 5 Value5
01/01/2005 6 Value6
01/01/2005 7 Value7
01/02/2005 1 Value1
01/02/2005 2 Value2
01/02/2005 3 Value3
01/02/2005 4 Value4
01/02/2005 5 Value5
01/02/2005 6 Value6
01/02/2005 7 Value7
There are 450 "ID"s per day and there will be ~30 days per month that
repeat these 450 IDs and values. I could potentially reduce this to
between 80 and 100 IDs. I would like to create a table that looks
like:
Date ID1 ID2 ID3 ID4 ID5 etc...
01/01/2005 Value1 Value2 Value3 Value4 Value5
01/02/2005 Value1 Value2 Value3 Value4 Value5
01/03/2005 Value1 Value2 Value3 Value4 Value5
What is the best way to do this? Any built-in SQL commands to assist?
Any tricks with DTS?
Thanks!

You're looking for a crosstab query: http://www.aspfaq.com/show.asp?id=2462
If the number of IDs is fixed, then a TSQL solution is possible (see below),
although with 450 IDs you might want to write a loop to generate the SELECT
statement. If things become more complex, or if the number of IDs can vary,
then it would be worth looking at a front-end solution or reporting tool.
Simon
select
date,
max(case when ID = 1 then Value else null end) as 'Value1',
max(case when ID = 2 then Value else null end) as 'Value2',
max(case when ID = 3 then Value else null end) as 'Value3',
...
from
dbo.MyTable

date

Hi,
I would like to transpose a table in mysql. I have looked on the web for

What I would like to do is to use the values in a row as column headings
during output, so that I can enter different sets of data into the same

I am a bit flummoxed by the problem of how to transpose "normalized" (in the
database sense) data records into columns of for a data entry form, and then
back again when the user is finished.
My previous solution to this was to filter by query or SQL for the
observations for a particular set of criteria, then go through the resulting
records and assign them to a non-normalized work table containing ONE RECORD

Dear All,
I'm attempting to create a query that will transpose repeated fields
into a single table structure. Can anyone think of how this can be done
as I'm stumped at the minute? I'd like to do this without having to
create a cursor due to the overheads and performance issues associated
with cursors. The table may also include additional fields which I'm
not interested in.

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,...
