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

How to fetch last record from the table to display in screen painter?

Hi Gurus,
              I have a requirement where i have to fetch the last record value in the table.
I have a screen where the TEXT name is REQUEST and I/P field name is REQ and SAVE push button.
In this I/P field automatically 1 should display when i excecute the program and when i save this, the request number should turn to 2 that is dynamically..once agin save then 3 and so on....and this 1, 2, 3 will be storeing in table.
I have succeeded till generating the values dynamically and saving in the table like 1 is displayed and when i click save it is changeing to 2..but the problem is when i am coming out of program and logon again the request number is again displaying as 1 rather it has to start with 4 because already 3 request are there in the table.
My code is...
Table zsave.
data declarations....
data req type i.
req = 0.
req = zsave-req.
PROCESS BEFORE OUTPUT
req = 0.
select req into table fun_st from zsave.
req = zsave-req.
zsave-req = req.
req = zsave-req + 1.
PAI
req = zsave-req + 1.
zsave-req = req.
when 'save'.
wa_funst-req = zsave-req.
Please can you provide me with the solution....answer will be rewared.
THKS

Can you tell me, when updaing the ZSAVE table with the counter value are you modifying the exisiting value or inserting the value as new record?
From the code in your first post, i see that you are extracting records into internal table but when you are moving to variable REQ, you are moving from table work area which is blank, so everytime when you execute it may be starting as 0.
Hope below code can help you understand on handling your requirement
Global Declaration:
>DATA: l_req TYPE i.
PBO:
SELECT MAX( req ) INTO l_req FROM zsave.
l_req = l_req + 1.
PAI:
DATA: wa TYPE zsave.
CASE ucomm.
WHEN 'SAVE'.
    wa-req = l_req.
    INSERT zsave FROM wa.
ENDCASE.

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.

Issue with fetching a record from IHPA table with PARNR value as condition

Hi All,
I am trying to fetch a particular record from IHPA table where i am giving the OBJNR number, PARVW and PARNR as customer no. , But I am not getting any record but if i will give OBJNR and PARVW it will generate a record with having same PARNR value.
Example :
case 1st :-
when i am passing following values in IHPA table,
OBJNR = IE000000000010070910
PRAVW = BP
PARNR = 620000562
it is not generating any record
case 2nd:-
But if i will pass
OBJNR = IE000000000010070910
PRAVW = BP
it will generate a record?(one row) which will include PARNR as same 620000562 along with other value.
Q1 - Why it's not generating in case 1st,
Q2 - How I will resolve this issue ? as i have to link some table as EQUI -
IHPA -
VCKUN
VCNUM ?
      I have written a code for this to join :
     SELECT A~EQUNR
       B~PARVW
       C~CCNUM
       D~CCNUM
       FROM EQUI AS A JOIN IHPA AS B ON AOBJNR = BOBJNR
       INNER JOIN VCKUN AS C ON BPARNR = CKUNNR
       INNER JOIN VCNUM AS D ON CCCNUM = DCCNUM
       APPENDING CORRESPONDING FIELDS OF TABLE IT_OBSO
       WHERE A~EQUNR IN S_EQN.
             AND PARVW = 'BP'.
      But it is not generating any record but when i am commenting the PARVW i am getting the mixed record of PARVW as (BP,SP,SH)
Let me know if any more clarification required.
Highly appreciate your help
Thanks & Regards
Shaw

Hi Santosh,
Thanks for your quick response.
But I am Sorry, I already checked with putting Zero before PARNR.
The issue is still as it is.
Thanks

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.

Need help for SQL SELECT query to fetch XML records from Oracle tables having CLOB field

Hello,
I have a scenario wherein i need to fetch records from several oracle tables having CLOB fields(which is holding XML) and then merge them logically to form a hierarchy XML. All these tables are related with PK-FK relationship. This XML hierarchy is having 'OP' as top-most root node and ‘DE’ as it’s bottom-most node with One-To-Many relationship. Hence, Each OP can have multiple GM, Each GM can have multiple DM and so on.
Table structures are mentioned below:
OP:
Name Null Type
OP_NBR NOT NULL NUMBER(4) (Primary Key)
OP_DESC VARCHAR2(50)
OP_PAYLOD_XML CLOB
GM:
Name Null Type
GM_NBR NOT NULL NUMBER(4) (Primary Key)
GM_DESC VARCHAR2(40)
OP_NBR NOT NULL NUMBER(4) (Foreign Key)
GM_PAYLOD_XML CLOB
DM:
Name Null Type
DM_NBR NOT NULL NUMBER(4) (Primary Key)
DM_DESC VARCHAR2(40)
GM_NBR NOT NULL NUMBER(4) (Foreign Key)
DM_PAYLOD_XML CLOB
DE:
Name Null Type
DE_NBR NOT NULL NUMBER(4) (Primary Key)
DE_DESC NOT NULL VARCHAR2(40)
DM_NBR NOT NULL NUMBER(4) (Foreign Key)
DE_PAYLOD_XML CLOB
+++++++++++++++++++++++++++++++++++++++++++++++++++++
SELECT
j.op_nbr||'||'||j.op_desc||'||'||j.op_paylod_xml AS op_paylod_xml,
i.gm_nbr||'||'||i.gm_desc||'||'||i.gm_paylod_xml AS gm_paylod_xml,
h.dm_nbr||'||'||h.dm_desc||'||'||h.dm_paylod_xml AS dm_paylod_xml,
g.de_nbr||'||'||g.de_desc||'||'||g.de_paylod_xml AS de_paylod_xml,
FROM
DE g, DM h, GM i, OP j
WHERE
h.dm_nbr = g.dm_nbr(+) and
i.gm_nbr = h.gm_nbr(+) and
j.op_nbr = i.op_nbr(+)
+++++++++++++++++++++++++++++++++++++++++++++++++++++
I am using above SQL select statement for fetching the XML records and this gives me all related xmls for each entity in a single record(OP, GM, DM. DE). Output of this SQL query is as below:
Current O/P:
<resultSet>
 <Record1>
 <OP_PAYLOD_XML1>
 <GM_PAYLOD_XML1>
 <DM_PAYLOD_XML1>
 <DE_PAYLOD_XML1>
 </Record1>
 <Record2>
 <OP_PAYLOD_XML2>
 <GM_PAYLOD_XML2>
 <DM_PAYLOD_XML2>
 <DE_PAYLOD_XML2>
 </Record2>
 <RecordN>
 <OP_PAYLOD_XMLN>
 <GM_PAYLOD_XMLN>
 <DM_PAYLOD_XMLN>
 <DE_PAYLOD_XMLN>
 </RecordN>
</resultSet>
Now i want to change my SQL query so that i get following output structure:
<resultSet>
 <Record>
 <OP_PAYLOD_XML1>
 <GM_PAYLOD_XML1>
 <GM_PAYLOD_XML2> .......
 <GM_PAYLOD_XMLN>
 <DM_PAYLOD_XML1>
 <DM_PAYLOD_XML2> .......
 <DM_PAYLOD_XMLN>
 <DE_PAYLOD_XML1>
 <DE_PAYLOD_XML2> .......
 <DE_PAYLOD_XMLN>
 </Record>
 <Record>
 <OP_PAYLOD_XML2>
 <GM_PAYLOD_XML1'>
 <GM_PAYLOD_XML2'> .......
 <GM_PAYLOD_XMLN'>
 <DM_PAYLOD_XML1'>
 <DM_PAYLOD_XML2'> .......
 <DM_PAYLOD_XMLN'>
 <DE_PAYLOD_XML1'>
 <DE_PAYLOD_XML2'> .......
 <DE_PAYLOD_XMLN'>
 </Record>
<resultSet>
Appreciate your help in this regard!

Hi,
A few questions :
How's your first query supposed to give you an XML output like you show ?
Is there something you're not telling us?
What's the content of, for example, <OP_PAYLOD_XML1> ?
I don't think it's a good idea to embed the node level in the tag name, it would make much sense to expose that as an attribute.
What's the db version BTW?

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...
Thanks

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.

To fetch ALTERNATE records from a table. (EVEN NUMBERED)

suppose i having tABle employee columns empid,empname ,emplocation it having 20 rows and i want to fetch 10 records which are even how to write query
jitendra

it was interview question
Then you ask back to the interview: what do you mean with even rows? In a relational database there is no inherit number for a row. In fact a table is by definition an unordered set. Of course, we can extract only the even empid:s, but there is no guarantee
that there is exactly ten of them. Chance could have it that all empids are odd.
If the interviewer insists you can say that we can always run a query with row_number, but that frankly does not make any sense.
If nothing else, this sort of response may reveal what sort of interviewer you are talking to. Is is exactly as clueless as the question suggest? Or is he purposely asking you a stupid question to see if you are smart enough to call his bluff?
I don't know about interviews in general, but if I were interviewing people, I would certainly be impressed by someone who has the guts to object and come with sound objections. That is exactly the kind of people I want to work with.
