Getting the last added record

Hi,
Am developing an application that needs to record some info in a user table after adding a sales invoice. What i need is an object or method that could give me the info of the last record added in the AR invoices table, i tried using the GetNewObjectKey() but i'm not sure if this method works OK in a scenario where concurrence situations could be present, i mean in situations where multiple users could save documents at the same time, does not the method become imprecise?

Hi Oscar,
Have a look at the following post:

Hope this helps,

Query to get the last added record in a table for a particular id

T
Hi,
I have 2 tables A, B
Table A has id,name
Table B had parentid(foreignkey referring to ID in above table), record_type,created_timestamp
I want to get the last added record_type from Table B for all the ids present in Table A.

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. I know this is
a skeleton, but could you at least try to do good programming? Temporal data should use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums. And sample data also helps.
I have 2 tables: Alphas, Betas
CREATE TABLE Alphas
(alpha_id CHAR(10) NOT NULL PRIMARY KEY,
alpha_name VARCHAR(25) NOT NULL);
Why was that DDL so hard you could not write it? But your narrative about the second table does not tell us if it has a key. I will guess that it is also alpha_id, but thanks to your rudeness, that is all we can do.
CREATE TABLE Beta
(alpha_id CHAR(10) NOT NULL PRIMARY KEY
REFERENCES Alphas (alpha_id),
record_type CHAR(2) NOT NULL,
creation_timestamp DATETIME2(0) DEFAULT CURRENT_TIMESTAMP
NOT NULL,
>> I want to get the last added record_type from Table Beta for all the ids present in Table A.<<
Think about this. Since Beta.alpha_id is a FOREIGN KEY to Alphas, all of its rows will have a match to Alpha. The SQL engine does this for you!
SELECT *
FROM (SELECT alpha_id, record_type, creation_date,
MAX(creation_date) OVER () AS creation_date_max
FROM Betas)
WHERE creation_date = creation_date_max;

Different ways to get the last 5 records ordered by date

I have a query no that returns the tickets ordered by moddt, modification date,
I was thinking of adding a select on top, to get the last 5 records of that list the select already generates. An other way was to use that select to create a view,
and get the 5 last records that way. I also though of a possibly impossible cursor with a sequence, but hmm well I consider that not a good solution.
So I'm trying to find a way, using a select, the topmost select which is not completed yet, to get the last 5 records. Maybe I should just try the rownumber thing again or something likewise.
Select * from(
select * from(
Select ticketid, appliecatiecd, categorieid, substr(titel,&,200)||' ...' "titel", klantproriteitid, interneprioriteitid,
(select g.voornaam||' '||g.naam
from gebruiker g
Where g.gebruikerid = t.gebruikerid
And t.applicatiecd = NVL(:P0_applicatiecd, :F101_applicatiecd))"aangemaakt door",
(select s.statusdefoms "status"

Where s.statusid = t.statusid
And t.applicatiecd = NVL(:P0_applicatiecd, :F101_applicatiecd)) "status",

How can I get the last / newest record of a table?

Hi,
I am developing an ecard app that has a create greeting page, a preview page with edit and send buttons and an edit page.
I got he insert working, and on the preview page I created a master record page (displays all records), and delete all unecessary designs. Doing it this way also gives me the 'edit' button, so people are able to edit their page.
How do I get only the last record displayed though? At the moment it loops through all records and displays them in sets of 10. I found the variable that holds the totla count of records ('$totalRows_rs7417_content1'), but how do I (re-)write the script so it ONLY diplays the last record?
I need to get the ID of this record as I am writing this into the PARAMs of the object and embed tags of my message .swf (this picks up the ID and based on that sucks the greetings text out of the database via another php script.
Also, from this page, how can I send an email to the sender (ie creator of the message) as well as the recipient? Both email addresses are in the databse so should be part of the erecord returned.
Thanks,
Nik

OK, So how do I recreate what I got in a non-ADDT list?
well, when you´re just about to display one certain record, the term "list" is somewhat inappropriate anyway.
What you´d simply need to do IMHO, is using DW´s native functions to create the basic "SELECT * FROM table_name ORDEr BY ID DESC" query, add "LIMIT 1" manually, and display the desired "dynamic text" placeholders in 1 table cell -- don´t think there were any need for all the fancy stuff
(sorting, filtering etc) provided by ADDT´s list, as it´s just 1 record.
It also occurred to me just now that finding the last record that has been added *may-* notbe enough if the site gets used a lot by our executives (I am thinking of a situation where 2 or three peolpe create greetings at the same time and press submit and then getting each others messges rather than their own).
in this case you might want to additionally store the respective executive´s "kt_login_id" session variable -- because it´s this unique "identifier" which should be used to show the last inserted record of the person who actually inserted it, means adding a "WHERE submitter_id" equals the session variable kt_login_id - clause to the query.
When creating a non-ADDT list that´s at some point based on detecting a user session, you´ll BTW need to insert at line 1
I can't seemt o insert it on the page as it is looking for a insert, update or delete bahaviour on the page which of course I don't have
please search these forums for several posts I made which explain my "use dummy table" approach that´s made for cases when you actually don´t have anything to insert/update/delete, but need "something" for ADDT´s send email behaviours.

How to get the last inserted record from a table ?

:-) Hiee E'body
I work on Oracle 8i and need to get the last
record inserted in a table.
I have tried using rownum and rowid pseudo-columns
but that doesn't work.
Can you please help me out ?

I'm not sure about 8i features.
I assume here that you don't have 'Date-Time' stamp columns on the table which is the easiest way to determine the last inserted row in the table.
If not try the following :-
select address, piece, SQL_TEXT
from V$SQLTEXT
where upper(sql_text) like '%INSERT INTO TABLE_NAME%'
Substiute the TABLE_NAME with the name of the actual table.
Have fun.

Problem getting the last database record

I need to get the last record of my database. The only way i found to do this is to use cursor::get with DB_LAST flag.
But using it i don't always get the last record. For instance if the database contains 5000 records i am getting record number 4864 and so on.
What am i doing wrong?

The DB_LAST flag is the right one to use.
Are you sure the keys sort in the order you expect? In particular, check for little endian integers. Here is some Python code that might be instructive:
import struct
sorted([(struct.pack("<i", i), i) for i in xrange(5000)])[-1][1]Regards,

Getting the last 5 records

I was told I should do this by date, and not buy a number. He might still be right that by date is better. But I thought that by ticketnr makes also sense, because the latest ticket, is wel normally the most recent one. I've added the check although it might not be needed, so I may remove it later.
The idea behind it is that if, although a field that needs to be filled in would give an error if not being so, a field that needs to be filled in, isn't then that record can't be used. As that wouldn't be the case, I can remove that as well. That would make it less complex.
The idea was that records could have been deleted, so that you get 1185 1187 1188 1189 1190 . If you just take the 5 highest ticket numbers, you would only get 4 as one is missing. So I thought that if you include a check that check if the ticketid actually used or not. I suppose it would be nicer if one could write something similar to but therefore not the same:
if tikcetid(select ticketid into ticketidtotest from ticket where ticketid=tussenticketid;).used() = TRUE then;
Then you would be sure it is used, and it would just pick out the last 5 ones. There could be a problem with the dates if they are mixed up, but this could be a problem not just for this. So I think it would deserve a solution on the database.
I'm getting one error as it is now.

Getting the Last 100 Records

Dear all.
I have a Table with 4 million reocords,
Is there any way to view only the last 400 commands. Is there a command in oracle that gets the first 400 or last 400 records
Kindly Suggest

OK. Something like this will give you the last 400 from the most recent date(s).
select *
from
   select col1
         ,col2
         ,col3
         ,row_number() over (order by date_loaded desc) rn
   from   your_table
where rn <= 400;

Last added record key for UDO

Hi,
I create a UDO , how i get the last added record key after i add document ?
Please Advise. Thanks

Hi,
Or try oCompany.GetNewObjectCode().
Or if this dosent work try the following.... Before adding the record in the before action = True execute a simple query
select max(docentry) from OINV
And now store that in a variable and execute the same query after the record is added in the beforeaction = false and check if both are same, if not then u have a new record added.
Hope it helps,

How to get the last record from the database

I am using MS Access database and Swings as GUI. I want to get the last record of a particular column from the table and store it as a varaible.

Hi
To get Last record of resultset, you have pass some parameter in constructor of CreateStatement.In such case Resultset should be scrollable and Readonly
Example
objStatement=objCon.createStatement ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
mwwResultSet=cwwStatement.executeQuery(mwwSqlQuery);
while(mwwResultSet.next())
if(mwwResultSet.isLast())
//Fetch the required column record.
String abc=mwwResultSet.getString(1);
I think this will work. Try it.

Because the data that comes in comes from multiple timezones and there are hundreds of lines, our attempts at monitoring by just looking at the data leave something to be desired.

Getting the last active number purchasing info record

Hi,
I was trying to get the last active number of the purchasing info record.
As in the ME21N, while creating a purchase order, once we have entered the material number, the system automatically returns the adequate number of the info recored, but I could't identify (through debug) which was the function module or method call used to get it.
I will be really thankful if somebody could help.
Thanks & regards.

Thanks to all for your answers. I finally figured it out with the help of a functional consultant.
To identify the last active number purchasing info record, we retreive from table EINA, and there, the field LOEKZ should be empty.
Basically, we only have one info record number per couple material/vendor.

{color:navy}*int*{color} numResults = </code>myResultSet<code class="jive-code jive-java">.getRow();
</code>myResultSet<code class="jive-code jive-java">.beforeFirst();
</code>{noformat}
but being a streaming result set, beforeFirst() throws an exception...
So how do you get the number of records in that result set? I wanna avoid an extra count(*) query, so I would appreciate other solutions than that.

you see, for now I just use a count(*) query to get the number of records, but that's adding a lot of extra waiting time...Iterating over the result twice will surely be slower then doing the count(*).great! so what I got now is actually the fastest way there is... awesome...
If you get an exception, then you surely have a stack trace. That should tell you what happens, or at least where.com.mysql.jdbc.MysqlIO.checkForOutstandingStreamingData(MysqlIO.java:2066)
Why do you need to know the number of elements beforehand, anyway?I need to know the number of elements because the incoming data goes into a table. Now of course, I could use ArrayList<String[]> or something, but wouldn't that require more memory resources than Object[][] ?
No one can tell you that, at least not without more information (say, the stack trace for example).Here's the exception message:
java.sql.SQLException: Streaming result set com.mysql.jdbc.RowDataDynamic@10c0ef2 is still active. Only one streaming result set may be open and in use per-connection. Ensure that you have called .close() on any active result sets before attempting more queries.
