Retrive a record before the last inserted record

Hi,
I use simple select statement to retrive records where cola = 'Yes':
select * from tbl1
where cola = 'Yes';
The result gives me about 10 records with different date.
From the above result, I want to get the record right before the last inserted record according to the date field; which means I can not use MAX function (all I want just one record).
If I write a function to return a date and passes it back to the SELECT statement, I'll get a date for each record, which I don't want.
I know there's a way to do that in PL/SQL.
Plese help me.

select * from (
select * from
(select * from (select * from (table> order by <date> desc) where rownum < 3)
order by <date>) where rownum =1

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.

CREATING A TRIGGER THAT PICKS UP THE LAST INSERTED RECORD

Hello everybody
my question. is it possible to embed a sql query whitin a trigger? the thing is that when I have to insert the value, this actually would have to be retrieved from another table. It is an AFTER INSERT, but it needs to know which name I inserted in table 1 in order to also insert it into table 2.
More specifically. Imagine a table with usernames and passwords that I populate as I set them up
Then I need a trigger that as it sees that I have entered that username it takes it and populates another table with that plus a generated sequence that could be the result of some string function
CREATE OR REPLACE
TRIGGER GENERATE_SEQUENCE
AFTER INSERT ON USERS_TABLE
FOR EACH ROW
BEGIN
insert into GENERATED_SEQUENCES_TABLE (lastinserted_name,surrogate_key)
values(SELECT USERNAME FROM USERS_TABLE WHERE USERID....., SUBSTR (lastinsertedname¦¦ password), 1,12);
END;
so, this lastinserted name is what I am trying to retrieve. I mean if it is not madness to insert a sql query in the way I have done it, I could write in the query to select the highest ID from the PK and that would give me the last inserted name.
thanks a lot
Alvaro

In an insert trigger you can reference all the inserting values with :new.column_name, hence there's no need to select from the USERS_TABLE table:
CREATE OR REPLACE
TRIGGER GENERATE_SEQUENCE
AFTER INSERT ON USERS_TABLE
FOR EACH ROW
BEGIN
insert into GENERATED_SEQUENCES_TABLE (lastinserted_name,surrogate_key)
values(:new.USERNAME, ...);
END;

Fetching the last inserted record

How can I fetch the last record inserted into oracle table?

Hi Waleed / Bhavesh
In pure RDBMS terms there is no concept of a first / last record. Also the query that Bhavesh has give makes an assumption that emp_n have been sequentially or inserted in some form of continuous incremental format.
It is not adviseable to use ROWNUM and ORDER BY together since Oracle allocates ROWNUMs before it actually orders the data

Retrive last inserted record from database table

Hi,
some body inserting a record into table 'A' through some procedure/java program.i want to retrive the last inserted record from database table.records are not stored in order.Can any body help me.

In general, unless you are storing a timestamp as part of the row or you have some sort of auditing in place, Oracle has no idea what the "first" or "last" record in a table is. Nor does it track when a row was inserted.
- If you have the archived logs from the point in time when the row was inserted, you could use LogMiner to find the timestamp
- If the insert happened recently (i.e. within hours), you may be able to use flashback query to get the value
- If you're on 10g or later and the table was built with ROWDEPENDENCIES and the insert happened in the last few days and you can deal with a granularity of a few seconds and you don't need 100% accuracy, you could get the ORA_ROWSCN of the row and convert that to a timestamp.
If this is something you contemplate needing, you need to store the data in the row or set up some sort of auditing.

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.

Last inserted record

HI,
we have created a table with a field ID.
we have inserted 1000 records in that table,.
I want to retrieve only the last inserted record.
How it's possible?
is it possible with rowid?
e.g:
CREATE TABLE TEST(id number(2));
insert into TEST values(1);
insert into TEST values(2);
insert into TEST values(3);
insert into TEST values(4);
insert into TEST values(5);
In this case i want to retrieve only 5.
How we can achieve this?

There is no concept of order in a heap table. Blocks can be reused so the ROWID cannot ever be used to determine when a row was inserted. The only way to determine the last row that was inserted into a table is to use a timestamp and/or a sequence column. If you need to determine the last inserted row and you don't already have a timestamp or sequence column, you need to add one.

GET LAST INSERTED RECORD

I am fairly new to flex. So please bear with me no this
question.
I would like to get MYSQL ID of the last record I inserted.
MSQL has as function LAST_INSERT_ID() that is connection based and
will return the last id of the last inserted record. My thought was
in the function contained within the cfc to do 2 queries insert the
record and return the last id directly after (see below). However,
I don't know how I would read the results back into flex. I am
unsure how to write the event handler. Thanks
<cffunction name="insertUser" access="remote"

<cfargument name="FNAME" required="false" type="string"

<cfargument name="LNAME" required="false" type="string"
hint="LNAME"/>
<cfargument name="CLIENTID" required="false"
type="string" hint="NEW CLIENTID"/>
<cfquery name="insUser" datasource="DBT">
INSERT INTO CLIENT (SSN, FNAME, LNAME) VALUES (
<cfqueryparam value="#ARGUMENTS.SSN#"

<cfqueryparam value="#ARGUMENTS.FNAME#"
cfsqltype="CF_SQL_VARCHAR" maxlength="20"/>,
<cfqueryparam value="#ARGUMENTS.LNAME#"
cfsqltype="CF_SQL_VARCHAR" maxlength="30"/>)
</cfquery>
<cfquery name="qRead" datasource="DBT">
SELECT last_insert_id() AS CLIENTID
</cfquery>
<cfreturn qRead >
</cffunction>

I assume you have LCDS installed with CF and you are using
the remote object service,
<mx:RemoteObject
id="myService"
destination="ColdFusion"
source="full.path.to.cfc"
showBusyCursor="true">
<mx:method name="insertUser"
result="insertUser_result(event)" />
</mx:RemoteObject>
<mx:Scrpit>
private function insertUser_result(event:ResultEvent) {
trace(event.result);
event.result will be the id of the newly inserted record.
BTW, I would highly recommend you looking into the data
management servcie. the SQLAssembler can spare you of the CF code
for simple CRUDs like this.

Getting the last insert id

Hi there,
I'm trying to get the id of the last inserted record. Normally would use $last_id = mysql_insert_id() after the insert statemant but I can't work out how to get this value when I use a ADDT insert transaction.
Any help much appreciated.
Cheers

I´m locking this thread because the OP has additionally added a related question to an existing thread, and a solution to this problem has been provided there too: using mysql_insert_id() with the ADDT

How to find last inserted record in the table.

Version: Oracle 10g
I have a table called "Manufacture" and 3 columns as mfno,itemname,quantity.
How to find last inserted record in the table "Manufacture".
As i come to know that Rowid is not result perfect results. Please provide your inputs.

user13416294 wrote:

How to find last inserted record in the table "Manufacture".Not possible as your data model does not cater for it. That simple.
If there is a need to determine some order or associate some time to an entity, then that should be part of the data model - and a relationship, or one or more attributes are needed to represent that information. Thus your data model in this case is unable to meet your requirements.
If the requirements are valid, fix the data model. In other words - your question has nothing to do with Oracle and nothing to do with rowid, rowscn or other pseudo columns in Oracle. It is a pure data modeling issue. Nothing more.

Simple Query Question - How do I return the Last 3 records of a Table?

Question.
For example, I have a table that has 50 records.
How do I, specify in SQL to only return the last 3 records of the table.
Select a.* from table a where ????

I was just trying to show an example to a friend on
how something like this would work and if it was even possible. But it won't work. Here's a simple example:
SQL> create table emp
2 (id)
3 as
4 select object_id
5 from   all_objects
6 order by object_id;
Table created.
SQL> select *
2 from (select rownum rn
3               ,b.*
4         from   emp b)
5 where rn > ( select (max(rownum) - 3)
6                from    emp)
7 ;
        RN         ID
     40830      55891
     40831      55892
     40832      55893So far, so good. These are the "last 3" rows inserted. Now delete a bunch of rows and insert 3 new ones:
SQL> delete emp where id < 40000;
33423 rows deleted.
SQL> commit;
Commit complete.
SQL> insert into emp values (60000);
1 row created.
SQL> insert into emp values (60001);
1 row created.
SQL> insert into emp values (60002);
1 row created.
SQL> commit;
Commit complete.
SQL> select *
2 from (select rownum rn
3               ,b.*
4         from   emp b)
5 where rn > ( select (max(rownum) - 3)
6                from    emp)
7 ;
        RN         ID
      7410      55891
      7411      55892
      7412      55893Here's the problem. Even though the "last 3 rows" are 60000 - 60002, I still get the same ones as the first query.

Find the latest updated or the latest inserted record in a table

Hi All,
Thanks in advance
Just a simple question
How do we find the latest updated or the latest inserted record in a table ?
Provide some queries in SQL?

You can order by rowid desc to get lately inserted records, but I'm not sure about updated records.That is incorrect, Oracle might use old rowid's even in inserts and you cannot assure that the max(rowid) refers to the latest record.
If the table is created with rowdependencies one can use ORA_ROWSCN pseudo column to check on date/time when the last dml has been performed over that table. But, that has some limitations too, Old snapshots will be erased hence one can check the last dml with a time frame of few days.

Help with pulling records for the last 24 hours

Post Author: kbrinton
CA Forum: Formula
Hi,
I don't know what is wrong with me but I can not figure out how to get Crystal to pull records for the last 24 hours. I have a date field I can key off of but I can not figure out the formula or correct syntax to put in the Selection formula. Any help would be great!! Thanks

Post Author: SKodidine
CA Forum: Formula
No need to create any formula. In your record selection criteria type:
{table.date} in dateadd("h",-24,currentdatetime) to currentdatetime
If you just want the prior 24hrs and do not care about the time then replace 'currentdatetime' with 'currentdate'.
(currentdatetime - 24) will give you 24 days before and not 24 hours.

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