How to delete records from dynamic internal table.

Hi Experts,
Need urgent help!!!
Issue is with Dynamic internal tables.
Below is code written by me :
FORM select_query USING Lw_tabnam
                  TYPE t682i-kotabnr.
DATA : lw_line TYPE REF TO data,
          lw_line1 TYPE REF TO data.
    CREATE DATA Lw_line    TYPE (lw_TABNAM).
    ASSIGN      Lw_line->* TO   <WA_tbl>.
    CREATE DATA LW_LINE    TYPE STANDARD TABLE OF (Lw_tabnam)
                           WITH NON-UNIQUE DEFAULT KEY.
    ASSIGN      Lw_line->* TO <TBL>.
    SELECT * FROM (Lw_tabnam)
             INTO CORRESPONDING FIELDS OF TABLE <TBL>
             WHERE (t_keys).
Endform.
code is working fine.
here even the table name and where condition are dynamic,everything is fine upto this point.
Now i have to delete some record from <TBL> based on some conditons.
     for ex : ( here lc_fieldname is KUNNR)
      loop at t_kunnr.
          lw_tabix = sy-tabix.
        Read table <tbl>
                with key (lc_fieldname) = t_kunnr-kunnr ASSIGNING <wa_tbl>.
        If sy-subrc = 0.
        *Delete
        delete <tbl> from <wa_tbl>
delete <tbl> index lw_tabix.
        Endif.
     Endloop.
The above delete statement doesn't work ,even we can't use index as it gives a syntax error " something related to "index is not allowed in standard table or hash table.
Can you help me ab't how to delete records in Dynamic internal table?
Other option that i am thinking of is to create a static table of type dynamic table.
means, data itab type standard table of <tbl> .I know the syntax is wrong ,however is there any way to do this?
Thanks in advance ,
If you have any suggestion ab't this then do let me know.
bye,
Gaurav.

How to delete data from dynamic internal table

Hi,
I have dynamic internal table and I have some slection screen fields , using these selection screen fields
(select -options), I have to filter the data? assigning will work with READ , but I have select options not the parametre,
and also delete will not work for dynamic table..
as we cannot use assigning with delete..
So how to do this?
and one more thing is , I cannot filter the data while selection( in select, I cannot filter the data-> as it's not coming directly from table, it's coming from buffer),
so now after selection of data, I need to filter the data from dynamic table.
Is there any way to do this?
Regards,
Mrunal

Hi matt,
I tried with below code as you said. But I am getting dump. can you help?
here is my piece of code.
FIELD-SYMBOLS: <LS_DATA> type any,
                           <LT_DATA> TYPE table,
                            <L_FIELD> type any.
    ASSIGN <l_buffer_entry>-dataptr->* TO <LS_DATA>.
    ASSIGN <l_buffer_entry>-dataptr->* TO <LT_DATA>.
LOOP AT <LT_DATA> ASSIGNING <LS_DATA>.
ASSIGN COMPONENT 'BUKRS' OF STRUCTURE <LS_DATA> TO <L_FIELD>.
IF <L_FIELD> NOT IN SO_BUKRS.
DELETE <LT_DATA>.
ENDIF.
UNASSIGN <L_FIELD>.
ASSIGN COMPONENT 'BELNR' OF STRUCTURE <LS_DATA> TO <L_FIELD>.
IF <L_FIELD> NOT IN SO_BELNR.
DELETE <LT_DATA>.
ENDIF.
UNASSIGN <L_FIELD>.
ENDLOOP.
and here is the description of my dump:->>>
You attempted to access an unassigned field symbol
(data segment 32772).
This error may occur for any of the following reasons:
- You address a typed field symbol before it is set using ASSIGN
- You address a field symbol that points to a line in an internal table
that has been deleted
- You address a field symbol that had previously been reset using
UNASSIGN, or that pointed to a local field that no longer exists
- You address a global function interface parameter, even
though the relevant function module is not active,
that is it is not in the list of active calls. You can get the list
of active calls from the this short dump.

How to delete columns from a 2D array

Hi guys,
I read a matrix from a text file and I want to delete the first and last columns of the matrix. I've been trying to do it with delete from an array function but it doesn't do it the way I want. Any suggestions?

Keep in mind that by default, 2-D LabVIEW arrays are row-based. So though you might be thinking that the first indexing input for the 'index array' primitive is for columns, it is actually for rows. You can either select the second input for the 'index array', or, if you are like me and think better in columns, you can transpose the array before you operate on it. I recommend getting used to the order of the inputs for the array tools and forcing yourself into the LabVIEW convention, as it gets complicated if you need to invert an array before you operate on it, and then again after so that the array returns to row-centric order, which is what all the rest of the LV array tools are expecting
Good luck!

Delete rows from Tabular form

Hi,
Anyone knows how dynamicly delete rows from Tabular Form (on button click, button is as item)?
Thanks.

I am in a great fix. We had a test instance.. and we had a version apex 3.2.. But when the same application has been uploaded to prod.. we used apex 4.0.Why on Earth would you do this? The whole point of the testing is to verify that the application will work in the production environment: the first requirement for this is that the test and production environments are equivalent.
has any body is facing the same issue as mine..Yes, as is easily discovered by searching the forum...see Delete button doesn't work in tabular form after upgrade from APEX3.2 to 4.

Delete record from the form and from the database

hi,
i want delete record from the form and the database ,but the record is only delete from the from !!!
this is my code :
if //condition then
delete_record;
commit;
end if ;
Any solutions ??
thnx

You have unique key field(s) on the table you are trying to insert which actually restricts you from inserting the same value again.
When you are deleting the record and issue commit there is a record to be inserted in the table which is a duplicate that's why you are getting this unique error.
As oracle is not able to insert your commit fails and stops your deletion of record from table

but, consider

Hi Naren,
First get the index number of the IT_data table and store it in one variable whose declaration like this.
data: tabix type sy-tabix.
while reading the internal table it_data set the tabix variable.
tabix = sy-tabix.
Instead of the above use below one.
Delete it_data-objek
Use the Below statement it will delete the row from the internal table.
Delete it_data-objek index tabix
Thanks,
Chidanand

How to delete some date in target table at a mapping?

How to delete some date in target table at a mapping?
I extract date from source tabel into target table,
but before extract date I want to delete some date from target?
how to do?

Just to change a bit of terminology in the reply, within the mapping, click on operator properties and choose TRUNCATE/INSERT.
Note that truncate is dependent on constraints, so you probably must disable those before doing this. You can of course do DELETE/INSERT...

How to delete duplicate records in all tables of the database

I would like to be able to delete all duplicate records in all the tables of the database. Many of the tables have LONG columns.
Thanks.

Hello
To delete duplicates from an individual table you can use a construct like:
DELETE FROM
    table_a del_tab
WHERE
    del_tab.ROWID <> (SELECT
                            MAX(dups_tab.ROWID)
                      FROM
                            table_a dups_tab
                      WHERE
                            dups_tab.col1 = del_tab.col1
                      AND
                            dups_tab.col2 = del_tab.col2
                      )You can then apply this to any table you want. The only differences will be the columns that you join on in the sub query. If you want to look for duplicated data in the long columns themselves, I'm pretty sure you're going to need to do some PL/SQL coding or maybe convert them to blobs or something.

How to move data from a staging table to three entity tables #2

Environment: SQL Server 2008 R2
I have a few questions:
How would I prevent duplicate records, when/ IF SSIS is executed many times?
How would I know that all huge volume of data being loaded in the entity tables?
In reference to "how to move data from a staging table to three entity tables ", since I am loading large volume of data, while using lookup transformation:
which of the merge components is best suited.
How to configure merge component correctly. (screen shot is preferred)
Please refer to the following link
http://social.msdn.microsoft.com/Forums/en-US/5f2128c8-3ddd-4455-9076-05fa1902a62a/how-to-move-data-from-a-staging-table-to-three-entity-tables?forum=sqlintegrationservices

You can use RowCount transformation in the path where you want to capture record details. Then inside rowcount transformation pass a integer variable to get count value inside
the event handler can be configured as below
Inside Execute SQL task add INSERT statement to add rowcount to your audit table
Can you also show me how to Check against destination table using key columns inside a lookup task and insert only non
matched records (No Match output)
This is explained clearly in below link which Arthur posted
http://www.sqlis.com/sqlis/post/Get-all-from-Table-A-that-isnt-in-Table-B.aspx
For large data I would prefer doing this in T-SQL. So what you could do is dump data to staging table and then apply
T-SQL MERGE between tables (or even a combination of INSERT/UPDATE statements)
