How to get the last row of a database table.

HI ,
I want to get record exactly from the last row of a database table.
How is that possible?

Hi,
To fetch last record from an internal table, just do find the number of records in it and read using index.
DESCRIBE TABLE ITAB LINES L_LINES.
READ TABLE ITAB INDEX L_LINES.
You can also use LOOP .. ENDLOOP but the above method is better (performance wise).
using LOOP .. ENDLOOP.
LOOP AT ITAB.
**do nothing
ENDLOOP.
**process ITAB (Header record of ITAB).
**after ENLOOP, ITAB will have the last record of the internal table.
[here ITAB is internal table as well as header record.]
But what is the requirement?
If you are looking for the current record of an employee then you can use ENDDA = HIGH_DATE.
My advice is to review your requirement again and try to fetch only that record which you need.

I dont know what table names and fields you have but
say you have a table called XYZ which has a primary
key field called keyID.
So in order to get the last row inserted, you could
do something like
Select *
from XYZ
where keyID = (Select MAX(keyID) from XYZ);
Good Luckwhat gubloo said is correct ...But this is all in MS SQL Server I don't know the syntax and key words in MYSQL
This works fine if the emp_id is incremental and of type integer
Query:
select      *
from      employee e, (select max(emp_id) as emp_id from employee) z
where      e.emp_id = z.emp_id
or
select top 1 * from employee order by emp_id descUday

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.

How to get the last row in a resultset or query

Hi All
Say If I have a complex query which returns a resultset say 15 rows. Now I want to limit the output showing only the last row.
How can we do this

Keep in mind Oracle does not keep "row" order as such. Unlike a graphical type db like Access, Oracle will not always give you back the results in order.
Even if you were to use a sequence, your query is never guaranteed to give back the results in the order you are expecting. You must then give an order by statement to all queries expecting the order.
Your definition of last row too is vague - if it is in fact the greatest amount, use the inline view suggestion. If you simply want to see the last inserted row, consider adding a last_update_date column inserting the sysdate (by a trigger perhaps). This would then allow you to see the last inserted row.
Enjoy!

How to get the last row

I have 10 rows in my table and I have to retrive last row using rownum.
For this I use
SELECT * from <table_name>
where rownum<=10
minus
SELECT * from <table_name>
where rownum<=9
The result is no rows selected
In the same case if I use
SELECT rownum from <table_name>
Where rownum <= 10
minus
SELECT rownum from <table_name>
where rownum <=9
The result is 10
Why this happend.
If the result is 10, then why the row whose rowid is 10 is not retrived

All
Please bear in mind that ROWNUM is an attribute of the query NOT the table. The last row returned by an unORDERed SELECT statement may be the most recently inserted row but is not guaranteed to be so.
The only way of assuring yourself of returning the most recent row is either to timestamp all your tables with a date_created column or to use a primary key with an ascending value.

How to get the field row name of database from a form?

Hello experts,
I am newer in OIM and developments with the API's.
I have this environment,
one resource that have the attribute department
relationship with the database row
UD_RESOURCE1_DEPARTMENT and other resource with the same attribute in, UD_RESOURCE2_DEPARTMENT
I am programing one java class that put values in the
form field through the table name, sample,
UD_RESOURCE_DEPARTMENT.
I let some code:
# Hash table with the value of Department
myMap.put("UD_RESOURCE_DEPARTMENT", value);
# and save in the resource form
tcFormInstanceOperationsIntf tcform = (tcFormInstanceOperationsIntf)tcUtilityFactory.getUtility(dataProvider,"Thor.API.Operations.tcFormInstanceOperationsIntf");
tcform.setProcessFormData(Long.parseLong(formKey), myMap);
But this solution implies know the name of the field in the database and not is a global solution.
I am interesting in know how I can obtain the name of the
row field of the database for the atribute. Does anybody know how to obtain the row field name of database from an IT Resource or through the field name of the form?
Is this the correct way to store data in a form?
Thanks in advanced.

Hi,
Thank you.
I have seen this function in the OTN help, but how can i get the index number. My requirment is when saving the data, I need to save both the value and the element name into the database,
Also it is tabular block, more than one rows
Thanks again

How to get the latest row from my Logical Table Source?

Hi everyone,
I have a SALARY_HISTORY table that holds the Salary Date and the Salary Amount for an employee, as a simple example. In my Business Model, I want to have a Display Folder called "Current Salary" and use the Where Clause restriction to derive the latest salary for each of my employees.
In standard SQL Plus, I used a nested SQL statement, e.g. "where a.SalaryDate = (select max(b.SalaryDate) from SALARY_HISTORY b where b.employeeid = a.employeeid)".
Is there anyway in the "Where Clause" filter of the LTS to derive this type of a query?
I have tried things like "DB".""."SCHEMA"."AL_SALARY_HISTORY"."SalaryDate" = EVALUATE('SELECT_PHYSICAL MAX(SALARY_DATE) FROM "DB".."SCHEMA"."AL_SALARY_HISTORY" WHERE employeeid = %1)', "DB".""."SCHEMA"."AL_SALARY_HISTORY"."employeeid"). And I know I can't use any of the analytic functions in a where clause.
So how do I go about this other than creating a View in the database or creating a function in the database to give me the maximum salary date for my employee?
Thanks
Paul

Hi Paul,
You could achieve this requirement using a sub query. Briefly, the steps are
1. Just create one report with max(salary_date) for each employee.
2. Create another report with SALARY_DATE included.
3. Create a filter (Based on another analysis) on this report, as employee is in(Employee of report in step1) AND SALARY_DATE IS IN(SALARY_DATE of report in step1)(this is the max_salary_date for him)
You could notice that BI Server would send two queries to the backend for this info.
Hope this helps.
Thank you,
Dhar

Hi, San,
Here's one way:
WITH     sample_data     AS
     SELECT DATE '2011-04-04'     AS dt
     FROM     dual
SELECT dt
,     TO_CHAR (dt, 'WW')     AS week_num
,     NEXT_DAY ( dt - 1
           , TO_CHAR ( TRUNC (dt, 'YEAR') - 1
                  , 'Day'
           )          AS end_o_week
FROM     sample_data;Another way is to use date arrithmetic:
WITH     sample_data     AS
     SELECT DATE '2011-04-09'     AS dt
     FROM     dual
SELECT dt
,     TO_CHAR (dt, 'WW')     AS week_num
,     TRUNC (dt, 'YEAR')
      + (7 * CEIL ( (dt - (TRUNC (dt, 'YEAR') - 1))
            / 7
      - 1               AS using_date_arithmetic
FROM     sample_data;

How to get the last day of a month?

HI,
I want to know how to get the last day of a month.
In my JClient form, I tried to get it by using oracle.sql.Date method, that is:
lastday=oracle.sql.Date anydate.lastDayOfMonth();
But it does not work. The result is lastday=anydate.
Why?
Stephen

You can use the Calender class...
Calendar c = Calendar.getInstance();
and then something like...
c.add(c.MONTH, 1);
int dayOfMonth = c.get(Calender.MONTH);
c.add(c.DAY_OF_MONTH, - (dayOfMonth-1) );
other usefull functions are:
System.out.println(" YEAR : " + c.get(Calendar.YEAR));
System.out.println(" MONTH : " + c.get(Calendar.MONTH));
System.out.println(" DAY_OF_MONTH : " + c.get(Calendar.DAY_OF_MONTH));
System.out.println(" DAY_OF_WEEK : " + c.get(Calendar.DAY_OF_WEEK));
System.out.println(" DAY_OF_YEAR : " + c.get(Calendar.DAY_OF_YEAR));
System.out.println(" WEEK_OF_YEAR : " + c.get(Calendar.WEEK_OF_YEAR));
System.out.println(" WEEK_OF_MONTH : " + c.get(Calendar.WEEK_OF_MONTH));
System.out.println(" DAY_OF_WEEK_IN_MONTH : " + c.get(Calendar.DAY_OF_WEEK_IN_MONTH));
System.out.println(" HOUR : " + c.get(Calendar.HOUR));
System.out.println(" AM_PM : " + c.get(Calendar.AM_PM));
System.out.println(" HOUR_OF_DAY (24-hour): " + c.get(Calendar.HOUR_OF_DAY));

How to get the last error for while loop? I just want transfer the last error for while loop, but the program use the shift register shift all error every cycle.

What do you mean by "get" and "transfer"?
If the shift register is not what you want, use a plan tunnel instead.
Typically, programmers are interested in the first, not last, error.
Can you show us your code so we have a better idea what you are trying to?
