Select most recent date only

I'm quite new to discoverer so please bear with me.
I have a query that returns e.g. 16 records.
One of the fields is a date field.
What I want to do is put a condition on the date field so that it only returns the record with the most recent date.
Thanks.

let me explain it to u in detail
i have the following fields
CONTRACTNUM FIRMTYPE FIRM A FIRM B FIRM % NTP_ACTUAL
123456 P ABC XXX 96 MM/DD/YYYY
S XXX DEC 4 MM/DD/YYYY
P ABC XXX 96 MM/DD/YYYY
S XXX DEC 4 MM/DD/YYYY
Here the CONTRACTNUM IS unique and the firm% sum is equal to 100, but the record is repeating twice , under the same CONTRACTNUM......................any suggestions willbe of great help.
So for this i used the ROW_NUMBER() OVER(ORDER BY date_field DESC)
in my case : ROW_NUMBER() OVER(ORDER BY ntp_actual DESC).
Now it gives me a new field with the row_numbers and when i create a condition where the calculation is =1, it give me one record
I was using this , because for any given contract number .............it should bring the record with the recent ntp_actual date.
i hope i was clear.
Thnks

Select most recent DATE for an ID.

Hi All,
I need to SELECT the records with the most recent DATE for each ID. A DATE range is part of the selection criteria.
My data.
MY_ID MY_DATE
1684662 26-JAN-09
1424097 27-JAN-09
1684663 27-JAN-09
1684664 27-JAN-09
1684672 28-JAN-09
0689073 28-JAN-09
1052476 21-JAN-09
1052476 21-JAN-09
1360828 23-JAN-09
1684661 23-JAN-09
1052476 30-JAN-09
1052476 30-JAN-09
1052476 30-JAN-09
1052476 30-JAN-09
The code below works fine when selecting 1 ID in the SUBSELECT, but with multiple ID it still selects rownum=1 (of course). This as far as my thinking takes me.
SELECT my_id,
my_date
FROM
(SELECT my_id,
my_date
FROM my_table
ORDER BY my_date DESC
WHERE rownum = 1
AND *{color:#ff0000}my_id = 1052476{color}*
AND TO_CHAR(my_date,'YYYY/MM/DD') BETWEEN '2009/01/01' AND '2009/01/31';
If I could somehow pass the SELECT ID into the SUBSELECT WHERE clause I should have this done.
Any suggestions?
Thank You in Advance for Your help,
Lou

Selecting row by most recent date

I'm attempting to select a row where the time ends in :00 and
date is the most recent date or just the last record where time
ends in :00, either will do.
Once I have that record selected I need to query that query
to pull in the previous 3 records which will be times ending in
:15, :30 and :45 to round out that full hour of data for
processing.
It seems to me that this should be pretty easy but my CF
books are not helping me here.
Any Ideas?

Two things I do to make this sort of thing easier are:
1. Take baby steps. Start with one field and the date field.
Once you get that to work, add one or two fields at at time.
2. Comma control. This structure helps prevent extra commas
from slipping into your query.
select field1
, field2
, date
from yourtable join (
select field1 f1
, field2 f2
, max(datefield) maxdate)
from yourtable
where something
group by field1
, field2
) temp on field1 = f1 etc
where clause

Select "most recent" records in abap

Hi
how can I select the most recent records in a table by using the abap select statement.
Example: The 100 rows with the "highest" (most recent) sequence-numbers in a table with documents.
somehow like this:
    SELECT "most recent" * FROM draw
    INTO TABLE gt_doklist
    UP TO 100 ROWS
    where ...
Has anybody an idea?
Thanks in advance,
Willi

Actually I believe that all the answers are wrong.
I believe that there will never be a single statement. If you need to determine the last 100 records for a special user you first need to determine the highest document number.
this can be done by
select max( document_number ) into document_number from table where username = username.
Any descending sorting order or group by etc. will never make sure that you get the last one. For a simple reason What should the select statement look like that makes sure (in combination of any cursor applied)? Its impossible!
If you now need the latest 100 records for a single user its the same problem like buffered number ranges. There is no way to perform that task because there is no database routine or sql statement to do so. And 1.5 million records are too much to try out or select everything.
You could do an assumption that the last 100 for that user have been posted during the last 1000 or last 10.000 records, select them and filter out.
Alternative you can perform the following select statement for 100 times. Using an index on document number and user might not be such a performance killer if its only done for one user during his online dynpro process:
data: max_number type char10.
select max( documentnumber ) into max_number from table
where username = username into [structure].
max_number = max_number + 1.
do 100 times
select max( documentnumber ) from table intomax_number
where username = username and docnumber lt max_docnumber.
select * from [db_table] into [structure] where docnumber = max_number.
append [structure] to [table].
enddo.
Of course that just draft coding... apply if statements and so on...
Even though its pretty poor, its the only way to do. Any select statement will never garantee what records you will get if you do not restrict accordingly and if the restriction has to be made on document number, but if there is no way to get the max_number - [100 last records of this user], there is no solution using one statement.
Thats it.

"next" most recent date

Hello!
I have an order header record with a order line detail table.
ORDERS
OrderID > 1
ORDER_LINES
orderID1, line1, item1, date_due
1,1,ITEM1,01-MAR-07
1,2,ITEM2,15-MAR-07
1,3,ITEM3,01-ARP-07
I want to select the single next most recent date from order_lines where the date_due is the next future date closest to sysdate. There could also be several lines with dates beyond that, but I'm only interested in the next most recent line.
For the example above, if sysdate = 03-MAR-07 the query would return order 1, line 2 (with the date of 15-mar-07).
I've seen example in the forum with max(), however as pointed out, there could be several future line dates out there, I'm only interested in the next one from the current sysdate.
In addition there could be no lines at all that map to the order id, requiring a NLV type of test output.
Thanks!

Maybe like this?
SQL> select * from order_lines;
            ORDERID1                LINE1 ITEM1      DATE_DUE
                   1                    1 ITEM1      01-MAR-2007
                   1                    2 ITEM2      15-MAR-2007
                   1                    3 ITEM3      01-APR-2007
SQL> select *
2 from
3 (
4     select ol.*
5           ,dense_rank() over (partition by orderid1 order by date_due) dr
6     from   order_lines ol
7     where date_due > trunc(sysdate)
8 )
9 where dr = 1;
            ORDERID1                LINE1 ITEM1      DATE_DUE                      DR
                   1                    2 ITEM2      15-MAR-2007                    1

Most recent date (UDATE) from CDHDR table based on CDPOS

Hi,
I am working on one object where i stuck with one issue. The requirement is I have to retrieve the most recent date from CDHDR table based on CHANGENR in CDPOS table. Where i am doing FOR ALL ENTRIES on CDPOS table to get the MAX( date )and i got the error, that aggregate functions are not allowed except COUNT( * ) with for all entries.
Any thread which can solve this issue would help aswel.
Please guide me how to achieve this. <removed>
Edited by: Thomas Zloch on Mar 13, 2010 9:10 PM

Hi Li,
Thats was really helpful information , infact my requirement is same as what you said. I even checked in the table entries there is only one changenumber.
You said we can take the first record, i even did the same. But for TABNAME I have to pass 3 table name 'LFA1', 'LFB1' and 'LFM1'. For FNAME 'LOEVM', 'SPERR'. I have written the code as below.
SELECT objectclas
               objectid
               changenr
               FROM cdpos
               INTO TABLE i_cdpos_a1
               FOR ALL ENTRIES IN i_lfabm1
               WHERE objectclas = c_kred               "KRED

        IF sy-subrc EQ c_0.
          IF i_cdpos_a1[] IS NOT INITIAL.
Select UDATE from CDHDR based on CHANGENR in CDPOS.
            SELECT objectclas
                   objectid
                   changenr
                   udate
                   FROM cdhdr
                   INTO TABLE i_cdhdr_a1
                   FOR ALL ENTRIES IN i_cdpos_a1
                   WHERE objectclas = c_kred             "KRED
                   AND objectid EQ i_lfabm1-objectid               "Lifnr
                   AND changenr EQ i_cdpos_a1-changenr.   "(this is coming from CDPOS above selection)
Here i got UDATE which have all the dates from 3 tables. I have to display in the output the field value (X) of LOEVM and UDATE for LFA1, SPERR value and UDATE for LFA1.Same way for other two tables, I have to display the UDATE and its field value (X). Where UDATE should be most recent date respectively.
How can I populate the Recent date (UDATE) from one interal table for indvidual field values and table names.

Most recent date query..

Hi All..

that was only a sample data..so I kept 2 sub_names for a perticular pmry_id..my original data contains several sub_names(about 5) for a perticular pmry_id...
hope you gt my point..I'm not sure I understand.
If you have 5 sub_names that you're interested in, change the WHERE clause to have those 5 sub_names. The list after "IN" can have as few as 1 or as many as 1000 items. (I'm not too sure about the upper limit, and it may be version-dependent.)
If you want to include all sub_names, then omit the WHERE clause.

Most recent data first in table view

I am adding values to a display table like in the example, but I want the top row to be the newest data for the user to see.
It keeps adding to the bottom, and then the user would have to scrolll down to see all the data. Can I select somehow the most recent data or get the table to auto scroll as data is applied? I have tried shift registers as well but no luck.
Here is my VI
Thanks

Be aware that if you populate the table with a lot of data, its performance will get very slow. You can work around this issue by only writing data to the table which the table is actually displaying. To do this, you will need to use a scroll bar separate from the main table and the event structure to capture events. If you run into this issue, let us know so we can provide some sample code.

Highlighting the most recent date in a row

hi all
I have a series of 5 dates in a row. I would like to be able to highlight only the cell containing the most recent date (in respect to the current date) in each row.
There will be instances when there is no date in some of the cells.
Thanks for the help in the past, this and the other forums are awesome.

Jason is correct. It requires two tables.
I had started experimenting with this last night, but an outage at my ISP prevented posting at that time.
Conditional formatting of a cell depends on comparing the value in that cell with a fixed value contained in the rule; the rule itself cannot reference a different cell to pick up the comparison value. So you need to calculate a value in a cell on a second table, apply conditional formatting to that cell, and place it directly behind the cell containing the date to be highlighted.
Example:
Dates are in cells B7 to F7 of Table 1
Cell H1 is used to select the maximum date.
Table 2 is a single row table with no row or column header cells, and only 5 columns.
Select Table 1, open the Inspector, and use the Table inspector to set Cell Background to “None”
In Cell H1 enter: =MAX(B7:F7)
Go Insert > Table > Plain
Resize the new table (Table 2) to 1 row x 5 columns.
In A1 of Table 2, enter: =DATEDIF(Table 1::B7,Table 1::$H7,"D")
Drag the handle at the lower right of the cell to copy the formula into all five cells.
Click on A1.
Open the Inspector and choose the Cell Format inspector.
Check the Conditional Format checkbox, then click Show rules...
Set the rule to “Equal to... 0”
Choose a Fill colour to serve as your highlight colour.
Click on the next cell and repeat.
When you have applied the rule to all five cells, close the Conditional Format dialogue.
Choose all five cells. Open the Text inspector.
Click on the colour well.
Leave the text colour set at Black, but move the Opacity slider to 0%.
Close the Inspector and the Colors dialogue.
Select Table 2 and drag it into position covering the five cells with dates on Table 1. Use the Arrow keys to nudge it into exact alignment.
Go Arrange > Send Backward to move Table 2 behind Table 1. Repeat until you can see the dates on Table 1.

Barry

How to display maximum (most recent) date value in a query

hello,
I have the following query:
StudentNumber | ExternalOrganization | Date |         | NumbeOfAdmissions
0112                  050                            06/27/2007   1

My dilemma is how to display only the row that has the most recent Date, e.g. here I want to only see the row with student number 0234 and date 07/15/2008; everything else should be hidden.
I know it should be very simple....yes/no?
thanks

Most recent date with two other conditions met

Ok, so I'm sure somebody is going to suggest that I do a search first before posting on here. So let me assure you, that I have exhausted all search possibilities that I could possibly think of before registering to post on here. I've read a lot of good suggestions that got me just as far as I was getting on my own, because I couldn't find any posts of somebody asking exactly what I'm looking to do. I have tried quite close to 100 different formulas without achieving the desired results.
I'm a pilot, and I track all of my flights myself in a very well organized(I think so ) Numbers spreadsheet that I've been tweaking and perfecting over the past few years. I have created plenty of formulas in it, and they all work great...except ONE.
I've created a simplified version of the columns I am trying to match specific conditions with. Essentially, I need the formula to return the most recent date(column 1), that is completed during a night time flight status(column 2), that is equal to or greater than 1.0 flight hours(column 3).
As you can see, by evaluating the table below, the correct formula should return to me: 8-4-13
The closest I've come to getting the correct results was with a "LOOKUP" formula, but I could not figure out how to get it to properly assess whether it was equal to or greater than 1.0 hours of flight, thus returning me the wrong date EVERYTIME(the most recent night flight period).
I'm sure I've gotten close at least a few times, but I need some help getting this final formula figured out. I really appreciate anybody's input on this.
Date
Flight Status
Flight Hours
8-1-13
D
2.4
8-2-13
N
3.0
8-3-13
N
1.1
8-4-13
N
1.3
8-5-13
D
2.2
8-6-13
N
0.5
8-7-13
D
1.1

This may work and requires and extra column in your Data entry table (the one you provided in your post). You can hide this new column.
D2=IF(AND(C2>=1, B2="N"), A2, "")
select D2 and fill down as needed.
The table on the right is a summary table and is set up as follows:
B2=MAX(Data :: D)
I hope this is helpful

How to display record with most recent date in sapui5?

How do I get the numbers ipad app to plot a graph of dates against values, where the most recent date is on the right of the graph, but the most recent date is at the top rather than bottom of the rows in the table?
Also how can it be a line graph without plotting a circle at each value?
Thanks this is very frustrating

Make a copy of the table and produce your Line chart or Bar chart from the copy. Sort the copy into the order you want to see in your chart.
Alternately you could use a Scatter Chart...

iOS 7: sort email by most recent date? Beyond frustrating.

Agree. Mail search results are nearly useless, sorted in effectively random order. Major Apple FAIL.
Removing the other search buttons (from, subject, etc.) is also frustrating. Went from one-click simplicity to having to type in 'from:'. Serious inconvenience. Completely failed the WWSS (What would Steve Say?) test.
