Do we have a ROWID or equivalent in HANA ?

Hi,
We are in the process of putting our HR data into HANA. The existing Oracle system uses a lot of analytical functions like LEAD, LAG, FIRST_VALUE to manipulate data. I m manually coding for these functions which is making my life really tough. My life would become a little easier if I can find an equivalent to the Oracle concept of ROWID. In Oracle ROWID is a hexadecimal value which recognizes a row in the table. For example if a table has 2 duplicate rows then by using ROWID we can distinguish them. Do we have something similar in HANA ?
When HANA is planning to provide analytical function to calculate LAG, LEAD functions to calculate the previous n value and post n values of a row by partitioning the data. These are very essential and can not think of proceeding without these.
Thanks a ton in advance.
Regards,
Samarpan

For RowID it is a variable providing this information.
For example:
select  "$rowid$" from yourtable
is working and it is probably  providing like result what you  are expecting.
Nevertheless: $rowid$ is purely internal and non-documented. Because of that Richard mentioned that  Rowid functionality is not available.
Another option is to use SQL scripting where you have rownum() function fully supported.
Any way it is recommended to use Sql scripting because the calculation engine provide a better parallelisation of your queries.
HANA has also functions like LEAD, LAG ...and others working with MDX calls.
Next step wil be to provide all these analytical functions like SQL functionality.
At his stage any of this function can be achieve using modeling
I hope this will help you.

  • Does the Lumina 820 have Gorilla Glass or equivale...

    I am really liking the new Lumina 820 and it sounds like it could be one of the best new phones for the money.  One issue is in the specs it does not state it has Gorilla Glass.  Maybe that is an omission (the 800 has it) or maybe an equivalent "tough" glass is used?  If not this would be a deal breaker as I am not wiling to go back to using stone age screen protectors!
    Thanks, Mike

  • What is the SQL ROWNUM equivalent in HANA SQL script

    Hi,
    Could any one let me know what is the ROWNUM equivalent in HANA? Thanks for the help.
    Thanks,
    Jyothirmayi

    Hi Jyothirmayi,
    ROW_NUMBER() OVER (ORDER BY <FIELD LIST>) is the function to generate row numbers.
    ORDER BY clause is mandatory to generate row numbers in HANA.

    How do I get a refund for my iCloud purchase? I purchased the $100.00 one and my data was too large so it could not be backed up

    Refund:
    If in the US, follow the link below (you must request a refund within 15 days) -

  • Form based on view: ROWID error??? (please help)

    I have a report. One of the columns is linked to a form that is based on a view. When i click the link, I get:
    Cannot link to the module: 5049492634 ORA-01446: cannot select ROWID from view with DISTINCT, GROUP BY, etc. (WWV-16062)
    An unexpected error occurred: ORA-01446: cannot select ROWID from view with DISTINCT, GROUP BY, etc. (WWV-16016
    That seems fair: views do not have ROWID's. How can I make it work??? In the ORDER BY settings from the form, I can choose ROWID, but as far as i am concerned, a view does not have one...
    I really need this to work.
    Thx.
    Paul.

    View should have a rowid. To create a rowid tables have to have foreign key relation. And also in where clause you should have PK-Field-Name=FK-Filed-Name statement.

  • Oracle Equivalent user

    Hi,
    OS: IBM-AIX
    Oracle: Oracle10g 10.2.0.3.0
    I created Oracle user with relavent groups. With logging in as oracle user, I can perform DBA activities.
    My senario is that, I have to create oracle equivalent user say (neworacle). So I have created neworacle user in unix and assigned Oinstall and dba groups.
    I try to login as 'neworacle' user and try to take export of a schema.
    I get the following error
    Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production
    With the Partitioning, OLAP and Data Mining options
    ORA-31626: job does not exist

    ORA-27092: size of file exceeds file size limit of the process

    Are this errors cause due to exporting dump through a new user 'neworacle'?
    Is it possible to perform oralce activities using 'neworacle'?
    Thanks in advance

    Why did you need to give access to datafile 5 to the new user? In fact to change my question to a statement. You should not have had any need to give access to the datafiles to any users.The oracle account should own them and that manages all access to them.

  • Error ORA-01446:cannot select ROWID  - Bug?

    Hi
    I am getting an error message in SQL Developer 3.0.04.34
    Error ORA-01446:cannot select ROWID from view with DISTINCT, GROUP BY, etc.
    (you can read the full details at http://www.techonthenet.com/oracle/errors/ora01446.php )
    when I create a view containing "DISTINCT" even though it doesn't have a rowid anywhere in the select.
    Is this a bug? The view seems to function well enough but sql developer itself seems to be struggling a bit.
    I have found accounts of similarish bugs on this site from about 2007 but relating to slightly different sets of circs, but if I am asking an old and obvious question then apologies in advance.
    C

    Hi C,
    Well, the question may be old (see at least: ORA-01446 error in SQL Developer 3EA4 but I doubt it's obvious.
    The simplest cases of create view ... as for the following selects
    select distinct deptno from dept; 
    select deptno, count(*) employees from emp group by deptno;work fine in all the 2.x, 3.x releases in the object viewer data tab. Of course, running a select which includes a rowid on these views from a worksheet will fail as expected.
    In such situations a simple, reproducible test case is always nice but, at a minimum, please provide a listing of the broken code and a description of exactly how/where in SQL Developer the error occurs.

  • How to get ROWID...

    As a relative rookie to Apex and a long time Forms guy, I was searching for a way to get the ROWID... mostly as a security blanket (in case I needed it).
    I first tried to create a field in an HTML region called P5_ROWID, source type of Database Column and Source Value or Expression of ROWID.
    The page worked without error, but the P5_ROWID field was blank. (Can someone explain this one?)
    Then I set the source type to SQL Query and Source Value or Expression to select ROWID from Table where PK = :p5_PK
    Now I have the rowid...
    Does anyone see a problem with this solution?

    Hi,
    Besides the fact that you're using the ROWID column when you already have a primary key, no.

  • ROWID confusion

    According to the docs, ROWID represents the physical address of the row and is unique in the entire database.
    http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96524/c13datyp.htm#17757
    So, select max(rowid) from a table, I think, will display the latest inserted row from the table. The latest row of course, is inserted next in the available memory (data file or block). My question here is, if for eg: a row is inserted in the physical location represented by rowid AAANH1AALAAAAIiAAA, the next inserted row gets inserted at AAANH1AALAAAAIiAAB and so on. If I delete the row with rowid AAANH1AALAAAAIiAAA and assume we run out of blocks or free space for any new row to be inserted. As AAANH1AALAAAAIiAAA physical address got freed because of deletion earlier, is there any possibility that the newly created row goes to the this address representing the rowid AAANH1AALAAAAIiAAA?
    I might've confused you guys with the question. Please let me know if you need further clarification. You are welcome even to conclude my question as an utter non-sense. I always thought max(rowid) is another alternative for selecting latest inserted row in the table. If it is not, please let me know why!
    To put my question short, is there any possibility that if a row with certain ROWID (AAA) gets deleted, any further new row can have this ROWID AAA as ROWID after all represents the physical location of the row?
    Cheers
    Sarma.

    Sarma,
    I think you got your answer for the situation when rowid is reused after being deleted.
    I would like to add that even if you never delete rows from the table, the assumption that max(rowid) means latest row is incorrect.
    rowid is the physical address of the row.
    This physical address consists of
    data object id,
    relative file number within the tablespace where data object resides,
    block id within the datafile,
    row number within the block.
    If your data object is in a tablespace with multiple data files, then latest row can be inserted into extent in datafile 1, but if there are any (even older) rows in datafile 2, all of their rowids will be greater than those in datafile 1.
    In fact, when you create a tablespace with multiple datafiles, then load data into a table in this tablespace, the extents for this table are usually created in round-robin fashion in all the datafiles that have enough free space to allocate next extent.
    Moreover, even with single datafile, if you ever free any space at the beginning of the file (drop or truncate a data object), then your table may create a new extent in the newly freed space at the beginning of the file.
    Then, some of the new rows may be created in the beginning of the file and their rowid will be less than for older rows at the end of the file.
    For partitioned tables there are even more variations because each partition has its own data object id (first four bytes of the rowid).
