Delete Duplicates from internal table with object references

Hi
How can I delete duplicates from an internal table in ABAP OO based on the value of one of the attributes?
I have created a method, with the following code:
LOOP AT me->business_document_lines INTO l_add_line.
 CREATE OBJECT ot_line_owner
 EXPORTING
 i_user = l_add_line->add_line_data-line_owner
 i_busdoc = me->business_document_id.
 APPEND ot_line_owner TO e_line_owners.
ENDLOOP.
e_line_owners are defined as a table containing only object references.
One of the attribute of the object in the table is called USER. And I would like to do a "delete ADJACENT DUPLICATES FROM e_line_owners", based on that attribute.
How can do this?
Regards,
Morten Nielsen

Hello Morten
Assuming that the instance attribute is public you could try to use the following coding:
SORT e_line_owners BY table_line->user.
DELETE ADJACENT DUPLICATES FROM e_line_owners
 COMPARING table_line->user.
However, I am not really sure (cannot test myself) whether TABLE_LINE can be used together with SORT and DELETE.
Alternative solution:
DATA:
 ld_idx TYPE sy-tabix.
LOOP AT e_line_owners INTO ls_line.
 ld_idx = syst-tabix + 1.
 LOOP AT e_line_owners TRANSPORTING NO FIELDS FROM ld_idx
 WHERE ( table_line->user = ls_line->user ).
 DELETE e_line_owners INDEX syst-tabix.
 ENDLOOP.
ENDLOOP.

Delete duplicate from internal table

HI Abapers,
I have a query on how to remove the duplicates from an internal table
My internal table data is as follows :
Cno Catg1 Catg2
01 0 1000
01 2000 0
I want to get only one record as
01 2000 1000
How to get the result.
I tried sorted by cno and used delete duplicates but it was not helpful.
Is there any other alternative to get this done
Please help me.

Priya

check it out with delete adjacent duplicate records
Deleting Adjacent Duplicate Entries
To delete adjacent duplicate entries use the following statement:
DELETE ADJACENT DUPLICATE ENTRIES FROM <itab>
 [COMPARING <f1> <f 2> ...
 |ALL FIELDS].
The system deletes all adjacent duplicate entries from the internal table <itab>. Entries are duplicate if they fulfill one of the following compare criteria:
Without the COMPARING addition, the contents of the key fields of the table must be identical in both lines.
If you use the addition COMPARING <f1> <f 2> ... the contents of the specified fields <f 1 > <f 2 > ... must be identical in both lines. You can also specify a field <f i > dynamically as the contents of a field <n i > in the form (<n i >). If <n i > is empty when the statement is executed, it is ignored. You can restrict the search to partial fields by specifying offset and length.
If you use the addition COMPARING ALL FIELDS the contents of all fields of both lines must be identical.
You can use this statement to delete all duplicate entries from an internal table if the table is sorted by the specified compare criterion.
If at least one line is deleted, the system sets SY-SUBRC to 0, otherwise to 4.

Deleting Duplicates from a table

Its a huge table with 52 fields and 30k rows. I need to delete the duplicates based on one of the fields. GROUP BY is taking a lot of time. Is there a quicker way to delete the duplicates using SQL.
Thanks.

How many duplicates have you got? Do you have even a vague idea? 1%? 20%? 90%?
One way would be to add a unique constraint on the column in question. This will fail, of course, but you can use the EXCEPTIONS INTO clause to find all the ROWIDs which have duplicate values. You can then choose to delete those rows using a variant on teh query already posted. You may need to run %ORACLE_HOME%\rdbms\admin\utlexcptn.sql to build the EXCEPTIONS table first.
This may seem like some unnecessary work, but the most effective way of deleting duplicates from a table is to have relational integrity constraints in place which prevent you having duplicates in the first place. To paraphrase Tim Gorman, you can't get faster than zero work!

Deleting entry from internal table

Hi Experts,
i have the following internal table:
data : it_result1 TYPE crmt_object_guid_tab
and work area
data : wa_result1 type crmt_object_guid.
i have to delete a guid from internal table based on some condition.
loop at it_resul1 into wa_result1
if lv_priority eq priority.
delete this entry from internal table.
endif.
endloop..
i tried using delete table it_result with table key CRMT_OBJECT_GUID = wa_result. but this is giving syntax error.
what should be done to delete the entry?
Thanks and regards
Shilpi

Hi
Check Syntax for DELETE operator on pressing F1
1. DELETE itab.
2. DELETE TABLE itab WITH TABLE KEY k1 = v1 ... kn = vn.
3. DELETE TABLE itab [FROM wa].
4. DELETE itab INDEX idx.
5. DELETE itab FROM idx1 TO idx2.
6. DELETE itab WHERE logexp.
7. DELETE ADJACENT DUPLICATES FROM itab.
delete table it_result with table key CRMT_OBJECT_GUID = wa_result
this is wrong
delete it_result where CRMT_OBJECT_GUID = wa_result

wa_tab TYPE mara.
wa_tab-matnr = '1000'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '1001'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '1002'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '1003'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '2001'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '3001'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '4010'.

Duplicates From Internal Tabl

Hello,
I have an internal table with 6 fields and if the first five fields are same then its called a dublicate and I shud collect these duplicates in an other table moving the original to the other internal table. So from the basic Internal table I need to form 2 tables one with originals and the other with duplicates..How do i do this?
Thanks
Viky

Hi
Say itab is your first table and
    itab2 is table of the same type as itab
wa_itab and wa_itab are work areas of the type of your internal table.
Loop at itab into wa_itab.
clear cnt.
Loop at itab into wa_itab1 where field1 = wa_itab-field1
                                               field2 = wa_itab-field2
                                               field3 = wa_itab-field3
                                               field4 = wa_itab-field4
                                               field5 = wa_itab-field5
cnt = cnt + 1.
If cnt gt 1.
append wa_itab1 to itab2.
DELETE itab from wa_itab1.
endif.
Endloop.

Reg deleting entries from internal table

Hi experts,
 I have two internal tables , ITAB1 and ITAB2 (same structure), i like to delete the records from ITAB1 which are in ITAB2 without looping .How it can be done?
regards,
Kannan

Lozan,
itab1 is having 1,2,3,4.
itab2 is having 1,2,5,6,7.
Now I move the contents in itab1 and itab2 to itab3.
itab3 is having now 1,2,3,4,1,2,5,6,7.
Now I will sort this itab3,thus itab3 is now having
1,1,2,,2,3,4,5,6,7.
Now,if I use delete adjacent duplicates from itab3,will it won't result in
1,2,3,4,5,6,7 in itab3?

Deleting duplicates from a table ,who's size is 386 GB

Need to delete duplicate records from the table.Table contains 33 columns out of them only PK_NUM is the primary key columns. As PK_NUM contains unique records we need to consider either min/max value.
Sample data :
PK_NUM
Name
AGE
1
ABC
20
2
PQR
25
3
ABC
20
Expected data should contains only 2 records:
PK_NUM
Name
AGE
1
ABC
20
2
PQR
25
*1 can be replaced by 3 ,vice versa.
Size of table : 386 GB
Total records in the table : 1766799022
Distinct records in the table : 69237983(Row distinct with out Primary key)
Duplicate records in the table : 1697561039(Row duplicates without primary key)
Column details :
4 : Date data type
4 : Number data type
1 : Char data type
24: Varchar2 data type
DB details : Oracle Database 11g EE::11.2.0.2.0 ::64bit Production
My plan here is to
Pull distinct records and store it in a back up table.(ie by using insert into select)
Truncate existing table and move records from back up to existing.
As data size is huge ,
Want to know what is the optimized sql for retrieving the distinct records
Any estimate on how much it will take to complete (insert into select) and to truncate the existing table.
Please do let me know ,if there is any other best way to achieve this.My ultimate goal is to remove the duplicates.

As data size is huge ,
Want to know what is the optimized sql for retrieving the distinct records
Any estimate on how much it will take to complete (insert into select) and to truncate the existing table.
@ 1. - Your best chance seems to be (should require a single FTS only)
create backup_table as
select pk,name,age,a_date,a_string,a_number, ...
from (select pk,name,age,a_date,a_string,a_number, ...
 row_number() over (partition by name,age order by a_date) rn
 from big_table
where rn = 1
@ 2. - Having statistics in place and (at least nearly) up to date explain plan should return an appropriate estimate

pls help me with logic.
thank you for helping me

Hello Guys,
It is not advisable to delete the entries from the internal table you are looping upon. See this thread: [Sy-tabix in loop : Doubt|Sy-tabix in loop : Doubt]
And to answer the OP's question select data into some local internal table & based on the condition populate your final table. Creating a local table of the same type as the final table will not create too much performance overhead

DELETED rows from internal table

Hi Experts,
If I delete row/s from an internal table
using the command DELETE ADJACENT DUPLICATES,
is there a way to get these deleted rows.
Thanks in advance.
Rose

Hi roselie,
1. ofcourse not.
2.hence, before that,
u can declare another internal table,
similar to original,
and use like this.
3. ITAB1[] = ORIGINALITAB[].

Deleting block from internal table with AT / ENDAT

Hi.
I have the following code:
sort itab by pred_doc.
loop at itab into wa_cust.
At end of pred_doc.
sum.
write :/ wa_cust-pred_doc, wa_cust-amount.
if wa_cust-amount = 0.
Delete entire block of this pred_doc
endif.
endat.
endloop.
Within that "IF" statement, I want to delete the entire block (all entries with that pred_doc). How do I do this? I'm not sure of the syntax. In other words, I just need to do subtotals of the internal table by pred_doc on amount. If the subtotal equals zero, the records for that pred_doc need to be removed from the internal table.
Thanks,
Clay

Hi,
I agree with Rob. Use two internal tables for this purpose.
data: itab1 like itab. New internal table which will hold the required entries
sort itab by pred_doc.
loop at itab into wa_cust.
At end of pred_doc.
sum.
write :/ wa_cust-pred_doc, wa_cust-amount.
if wa_cust-amount ne 0. " If the workarea has the subtotal entry with amount not equal to zero, then transfer it to a new internal table
append wa_cust to itab1
endif.
endat.
endloop.
Now itab1 will contain your required entries. But please note that this will be the 'summed up' entries and not the the individual entries before summing up.
Hope this helps!
Cheers,
Mahesh

Delete row from internal table using field symbol.

Hi friends,
I created dynamic internal table using field symbol. I want to delete some data using where clause.
for example. i want to use like,
DELETE <FS> WHERE KUNNR = WA_KNA1-KUNNR.
Like the above statment it won't work. How i can use delete with where clause in field symbols.
Hope any one can help me.
Thanks and regards
Srikanth. S

hi Srikanth,
I think you have to LOOP through the whole internal table and check each line and decide to delete or not:
LOOP at <itab> INTO <wa>.
ASSIGN COMPONENT 'KUNNR' OF STRUCTURE <wa> TO <field>.
CHECK <field> IS ASSIGNED.
IF <field> EQ WA_KNA1-KUNNR.
DELETE ...
ENDIF.
UNASSIGN <field>.
ENDLOOP.
hope this helps

Delete records from internal table using another internal table

HI,
I have two internal tables itab1 and itab2 which have same records initially.Later some records of itab2 are deleted .Then i want to delete those records from itab1 also ie,those records not found in itab2 .Is there any method other than looping.
So that itab1 again becomes equal to itab2.
Thanks in advance.
Sowmya.

Soumya,
Itab1 , Itab2 .
Before deleting the records from itab2 move those records to one more internal table itab3.
Now you have deleted records of itab2 in itab3.
SORT ITAB3,ITAB1 by your main key field.
LOOP AT itab3.
READ TABLE ITAB1 WITH KEY key field = itab3-
keyfield.
IF sy-subrc EQ 0.
DELETE itab1 where keyfield eq itab3-keyfield.
ENDIF.
ENDLOOP.
