Moving backward -last record to first

Hi!
How can we move bachward, last to first record as cursors are forward only in oracle
Thnaks in advance
Imran

Raghu: You have :System.Cursor_Record and :System.Trigger_Record. Depending on what you are doing, one of them will equal 1 when you are at the first record in the block.
Imran:
I have used server-side stored procedure to do that. If you have a block of records the user has displayed (Example, names starting in the middle of the alphabet), and he wants to see the rows that come BEFORE the first record, this is what you do:
Call the stored procedure, passing the key value of the first record in your block. It creates a cursor with a where clause: where key_val < parameter_value, and Order by key_val desc. Then open the cursor, and fetch some number of rows -- I use about 50, then close the cursor and pass the key value of the last record fetched back to the form.
Then I set the where clause of the block to say Where key_val >= Value_From_stored_procedure. Execute_Query, then do a next_record until I find the record with the key value equal to (or greater than) the key value I passed to the stored procedure.
Then loop forward with a Next_Record loop however many records are displayed in the block minus two. This leaves the block displayed with the record with the initial key value as the second row displayed, and the immediately prior record is at the top.
I have implemented this type of process from the key-PrevRec trigger if :system.trigger_record = 1. Or you can put a small square button above the top of the scroll bar, so when clicked, it executes the same process.

How to select last record or first record value in a formula?

Post Author: d111
CA Forum: General
I am using a query in a report that in addition to other columns, has a column of month labels like:
There are no unique identifiers or sequence fields that can be used. There is only 4 columns: the label and 3 percent columns.
Jan07Feb07Mar07Apr07etc.
I would like to show the range of months I am using in a label on the report showing the last and first records value. like: "Jan07 to Jun07".
I can not see how to use the functions maximun or minimum since it sorts the months alphabetically.
I would like to use a formula to just grab the first and last record. I can't seem to find any information on this anywhere.
Please advise and thanks.

Hmm... I suspect what you actually want is the minimum and maximum dates in the report, rather than the first and last records (even if they do happen to come out in date order). So you need to convert the text dates to real ones, and then pick the min/max values.
If so, try these:
Formula "ConvertToDate" (for details section) which converts your text field into a real date - suppress it once placed!:
//Since you have 2-digit years, this conversion assumes that all your dates are >=year 2000
numbervar the_month;if left({YourTable.YourField},3) = "Jan" then the_month:=1 elseif left({YourTable.YourField},3) = "Feb" then the_month:=2 elseif left({YourTable.YourField},3) = "Mar" then the_month:=3 elseif left({YourTable.YourField},3) = "Apr" then the_month:=4 else
//...etc etc you fill in the rest!
if left({YourTable.YourField},3) = "Dec" then the_month:=12;
date(tonumber("20"+right({YourTable.YourField},2)), the_month, 1);
Formula "Show Date Range" (for anywhere on the report) to show the min/max values of the dates;
totext (minimum({@ConvertToDate})) + " to "+totext(maximum({@ConvertToDate}))
If, however, you really just want the first and last records, and you want it at the top of your report as a title (eg: in the Report Header), then I can't see how it can be done without using a subreport that looks at the same dataset, but only displays the first and last records (using the formulas below).
Stick this in the details section, and call it "HoldRecords" and suppress it:
whileprintingrecords;stringvar first;stringvar last;if recordnumber = 1 then first:={YourTable.YourField}; //if its the first record that crystal is displaying, store it in a variableif recordnumber = count({YourTable.YourField}) then last :={YourTable.YourField} //and again, but for the last record
Now create another formula, and put it into the report footer:
evaluateafter({@HoldRecords});stringvar first" to "stringvar last //will display "Jan07 to Apr07"
NOTE: if you have the report ordered by anything, this'll throw the record numbering, and therefore the first and last records, therefore... urgh.
Hope this helps...

Want last record in internal table

Hi All,
I have two internal table. in one internal table all data are available. now i want last record on first internal table and store in second internal table.... so give me some logic or sample code......
Thanks
zeni

get the latest record from an internal table.
if you are using function module RH_READ_INFTY_1001 then <itab
> will always contain all the records betweebn specified period (taken from selection screen), but to retrieve the latest, sort the records by ENDDA and you will get it on top, then use INDEX 1 for that record only, and store the record in a <work_area>, finally get that record from <work_area> to <itab> it self. thats way your <itab> will hold only latest record.
(you can store <work_area> in <work_area_2> and then pass the record in to <itab>
or, you can store the <work_area> to a different <itab_2>).
   call function RH_READ_INFTY_1001
   tables
      i1001         = it_hrp1001
sort it_hrp1001 by endda descending.
read table it_hrp1001 into wa_hrp1001 INDEX 1.
refresh it_hrp1001.
append wa_hrp1001 to it_hrp1001.

How to restrict the last record and not moving to next reocrd

1) how to restrict the last record and not moving to next reocrd.
2) Also for the F6 key(for new record).

When you are on the last record, next-record will create a new one, so that my question is do you want to forbid new record creation.

Select first and last records in grouped results - Oracle 11g

Say I have the following information in an Oracle 11g table:
Qty
Production order
Date and time
20
00000000000000001
12-JAN-14 00:02
20
00000000000000001
12-JAN-14 00:05

12-JAN-14 00:20
30
00000000000000002
14-JAN-14 00:29
I would like to write a query that would return the following:
Qty
Production order
First
Last
80
00000000000000001
12-JAN-14 00:02
13-JAN-14 00:09
120
00000000000000002
12-JAN-14 00:11
14-JAN-14 00:29
That is, the sum of the Qty column grouped by Production order, and the date/time of the first and last records for each Production order.
I came up with a query that yielded this result:
Qty
Production order
First
Last
80
00000000000000001
12-JAN-14 00:02
14-JAN-14 00:29
120
00000000000000002
12-JAN-14 00:02
14-JAN-14 00:29
Which means that the First and Last columns show the overall first and last date / time of the whole table. Please note that this is a dummy table. Sorry I am now allowed to write the actual query
I came up with since work policies do not allow me to share it. Also, I tried with windowing functions such as rank()and row_number() but my user does not have enough privileges to do so.
Any help or hints will be greatly appreciated.

Due to the fact that Oracle does not record the rows in any particular order, it would be wrong that the "first date" would be the first row processed by the query.
Therefore you would have to supply some other column if you do not want to consider the table as ordered by date.
Also, any analytical functions will need you to supply the "order by" and if its the date, then just a simple query will do:
SQL>WITH Tab1 (Qty, Production_Order, Pdate)

Iphoto slideshow (9.5.1)is playing backwards. last slide to first.

My iphoto slideshow is playing backwards - last slide first. How can I reverse that?

Are you using an instant slideshow from an album? Instant slideshows cannot be manually sorted. Create a regular slideshow project with "File > New Slideshow". Then you have a better control about the arrangement of photos in the slideshow.

Format first and last record of result query

Hello
I have the following query
<tt>select 1 seq, 'This is First record' data from dual union all
select 2, 'Data ' || tname from tab union all
select 3, 'This was last record Last record' from dual
order by 1</tt>
When i spool this statement to a listfile with col seq noprint option i get:
This is First record
Data MLA_ACCESS_LIST
Data MLA_APPLICATIONS
Data MLA_VPD_PCK
Data MLA_VPD_TABLES
This was last record Last record
But i want:
This is First record MLA_ACCESS_LIST
Data MLA_APPLICATIONS
Data MLA_VPD_PCK
MLA_VPD_TABLES This was last record Last record
I tried it with 1 statement with usage of lead and lag, because first and last record have to differ from the other result records. But i get ORA-30484: missing window specification for this function
Is this possible with 1 statement or am i doomed to edit the results by myself?
Thanks Auke

Hi lizcam,
A. Use FCC at sender side, it will convert CSV to XML like this
Input XML
<documentName>
<recordset>
<record>
<Time>20110820</Time>
<ID>220DNE0220</ID>
<Quan>140.13</Quan>
<Volume>0.000</Volume>
<Auc>E01</Auc>
<No>0</No>
</record>
</recordset>
</documentName>
Create a target DT like this
Output XML
<recordset>
<record>
<StartTime>20110820</StartTime>
<EndTime>20110822</EndTime>
<Quan>140.13</Quan>
<Volume>0.000</Volume>
<Auc>E01</Auc>
<No>0</No>
</record>
</recordset>
In MM,
1.Time -> CopyValue[0] -> StartTime
2.Time -> below UDF -> EndTime
3.Quan -> Quan
4.Volume -> Volume
5.Auc -> Auc
6.No -> No
UDF u2013 Execution type u2013 All values of Queue
public void getLastTimeValue(String[] inputEndTime, ResultList result, Container container) throws StreamTransformationException{
result.addValue(inputEndTime[inputEndTime.length-1]);
B. At receiver use again FCC to convert XML to CSV.
FYI. If you want to optimize more, you can use
1.globalContainer concept OR
2.u201CAttributes and Methodsu201D, declare are String. Store the EndTime using one UDF and write another UDF to retrieve it.

First and Last Record

Hi everybody,
I have problem with first and last record.How can I specified that current record is first and last record.
it means that is any statement exist that determine :System.first_record is equal to :System.last_record.
It's very emergancy.
Thanks for your attention and your help.

You can try this:
if :system.cursor_record = '1' and :system.last_record = 'TRUE' then
-- this is the only record in block
end if;

How to "remember" data from the last or the first record printed on a page?

I'd like to put a column value from the last record printed on the first page into a placeholder column (or whereever) to use later but I haven't found any way to do that. Trying the assignment statement with a placeholder in a format trigger causes "REP-1323: Cannot have output columns in format trigger...". Any ideas?

Getting first and last records of a query(on a table)

Hello,
i want to display the first and the last serial number(table: OBJK ) against a particulat matnr and obknr.
how do i display only the first and only the last record of my query ?
hope i am comprehendedable..
Thanks..
Shehryar

SELECT min(sernr) max(sernr) into lfirst llast
from objk
where matnr = pmatnr
and obknr = pobknr.
---Lets say you already have the data in the internal table in that case..
SORT itab by SERNR.
read table itab index 1.
lfirst = itab-sernr.
sort itab by sernr descending.
read table itab index 1.
llast = itab-sernr.
