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 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 ?
:-) Have a nice time

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.

abhi,
just imagine the table to be BSEG or FAGLFLEXA... then what would be performance of the code ?
any ways,
jyotsna, first check if you have a pattern to follow like if the primary key field have a increasing number range or it would be great if you find a date field which stores the inserted date or some thing..
you can select max or that field or order by descending using select single.
or get all data.. sort in descending order.(again you need some criteria like date).
read the first entry. using read itab index 1

Inserting records from internal table to database table

Hi all,
i want to insert records from internal table to zDatabase table, can u plz guide me which statement is better in performance to insert the records.
1) insert one by one record from internal table
loop at itab.
insert ztable from wa.
endloop.
2) insert total records at a time
INSERT <dbtabname> CLIENT SPECIFIED FROM TABLE itab.
or let me know if any other statement is there with high performance.
i internal table contains nearly 40000 records.
thanks.

Hi,
Insert the entire table at atime rather than a record so as to increase the performance.
you can use INSERT <dbtabname> CLIENT SPECIFIED FROM TABLE itab.
or
MODIFY ZPRODUCT FROM TABLE GI_AFPO.

Raj.

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.

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.

Hi Nishant,
You can use the option ORDER BY in your SELECT clause.
This is the SAP Documentation for ORDER BY option.
Variant 1
...ORDER BY PRIMARY KEY
Effect
Sorts the selected lines in ascending order by the primary key of the database table. This variant is only permitted for SELECT * ....
Notes
Since views do not have a primary key, specifying ORDER BY PRIMARY KEY only makes sense with database tables. If, however, you do specify ORDER BY PRIMARY KEY with a view, all fields of the view are sorted in ascending order.
Variant 2
ORDER BY f1 ... fn
Effect
Sorts the selected records in ascending order by the specified column references f1 ... fn. If a list is also specified in the SELECT clause, the column references f1, ..., fn must appear in this list.
By supplementing the statement with DESCENDING, you can sort in descending order using any of the fields f1, ..., fn.
The default sort sequence is ascending order, but you can make this explicit by adding the addition ASCENDING.
Consider this code this will select the latest 10 records form DB table(Note can use Variant 2 for DB tables also.
REPORT zarun_1.
DATA : it_mara TYPE STANDARD TABLE OF mara WITH HEADER LINE.
START-OF-SELECTION.
SELECT * FROM mara

 ORDER BY matnr DESCENDING. "Specify the Key Fields here.

Deletion of a particular record from database table

hai friends,
i want to delete (or) insert particular record from predefined sap table... that is with out module pool programming... can i delete or insert a record to or from the table..
thanks in advance
@jay

hi,
ucan do it without module pool programming in your normal report program.
To insert a line into an index table, use the statement:
INSERT <line> INTO <itab> [INDEX <idx>].
<line> is either a work area that is convertible to the line type, or the expression INITIAL LINE. If you use <wa>, the system adds a new line to the internal table <itab> and fills it with the contents of the work area. INITIAL LINE inserts a blank line containing the correct initial value for each field of the structure.
To select the lines that you want to delete using a condition, use the following:
DELETE FROM <target> WHERE <cond> .
All of the lines in the database table that satisfy the conditions in the WHERE clause are deleted. The FROM expression must occur between the keyword and the database table.
You should take particular care when programming the WHERE clause to ensure that you do not delete the wrong lines. For example, if you specify an empty internal table in a dynamic WHERE clause, all of the lines in the table are deleted.
If at least one line is deleted, the system sets SY-SUBRC to 0, otherwise to 4. SY-DBCNT contains the number of lines deleted.

keerthi

Latest record from database table

Hi all,
I am using select statement on a database table. The table contains records, and each one has an effective date.
effective dt record Rate
01/01/1800 R1 40
01/01/2007 R1 30
01/01/1800 R2 40
I want to select rates corresponding to R1 and R2. For R2, the rate is 40, but i need the rate 30 and not 40 for R1, because rate 30 has the most recent effective date. Please tell me if i can do this in the select query itself...
Please help me...

Create Trigger to insert records from one table to another

I created the below trigger to move data from one table to another after records have been inserted from another table to that table. What I need done is that each time records have been inserted into TEST_TBL, one of these actions codes should be implimented: U-update, N-insert, D-delete and inserted into TEST_TBL1. But each time I run the script, I get bunch of errors. Please see the script below: - Your help will be appreciated.
create or replace
trigger POWER_tr

Hello
At the end of trigger show errors / and post what errors are you getting exactly?
Here is a simple example for your reference, this will save old values in history table; you can replace it with new values if that's what do you want.
CREATE OR REPLACE TRIGGER TRG_DU
   AFTER DELETE OR UPDATE
   ON EMPLOYEE    REFERENCING NEW AS New OLD AS Old
   FOR EACH ROW
DECLARE
BEGIN
   IF UPDATING
   THEN
      INSERT INTO employee_hist
        VALUES   ('UPDATE',
                  :OLD.empid,
                  :OLD.name,
                  :OLD.deptid);
   ELSIF DELETING
   THEN
      INSERT INTO employee_hist
        VALUES   ('UPDATE',
                  :OLD.empid,
                  :OLD.name,
                  :OLD.deptid);
   END IF;
EXCEPTION
   WHEN OTHERS
   THEN
      -- Consider logging the error and then re-raise
      RAISE;
END TRG_DU;
