Delete from database Table
Hi,
To delete data from database table using internal table I am using following statement.
DELETE dbtab FROM TABLE itab.
Itab is a sorted table.Just wondering if table type matters while deleting database entries using internal table.which is efficient table type for deleting records from database table?
Regards
Nilesh
Hi Nilesh
The row type of the internal table must be a data object with at least the same length and alignment as the key structure of the database table. The key is read according to the structure of the table line, and not that of the row type. It is a good idea to define the row type with reference to the structure of the database table.
From SAP Help
DATA: BEGIN OF WA,
CARRID TYPE SPFLI-CARRID,
CONNID TYPE SPFLI-CONNID,
END OF WA,
ITAB LIKE HASHED TABLE OF WA
WITH UNIQUE KEY CARRID CONNID.
WA-CARRID = 'UA'. WA-CONNID = '0011'.
INSERT WA INTO TABLE ITAB.
WA-CARRID = 'LH'. WA-CONNID = '1245'.
INSERT WA INTO TABLE ITAB.
WA-CARRID = 'AA'. WA-CONNID = '4574'.
INSERT WA INTO TABLE ITAB.
DELETE SPFLI FROM TABLE ITAB.
Besides, it is so technical what algorithm is run to delete records from the DB table when an internal table is given. If you want you can have a quick test using GET TIME. However, it seems logical that if your internal table is sorted with respect to any index, especially the primary index, of the DB table this may increase performance.

Dynamic record deletion from database table
Hi,
I need to delete selected records from database table(dynamic names). Table names are being passed from main program with some of their field names. The record to be deleted from the database table is being decided based on the fields passed for the table and their contains passed from the main program.
It is not possible to write dynamic where clause for DELETE statement directly.
So, I created a dynamic internal table and i am trying to fetch all records using SELECT statement(for which we can write dynamic where condition, something like...SELECT...WHERE (itab). ) which need to be deleted in the iternal table.
Piece of code :
CONCATENATE c_im v_tablefield1 INTO v_imprtfield1.
CONCATENATE v_tablefield1 c_in v_imprtfield1
into s_condition separated by space.
APPEND s_condition TO t_condition.
PERFORM GET_DYNAMIC_ITAB USING s_flds_agtab-tabname
changing t_itab.
ASSIGN t_itab->* TO <itab>.
*Select the data (to be deleted) from the database table
SELECT * FROM (s_flds_agtab-tabname) INTO TABLE <itab>
WHERE (t_condition).
*Delete the records from the table
IF SY-SUBRC = 0.
DELETE (s_flds_agtab-tabname) FROM TABLE <itab>.
ENDIF.
Here t_condition is of standard table of WHERETXT.
t_condition at the run time before giving dump was:
SPART IN IM_SPART
AND KUNNR IN IM_KUNNR
Here IM_SPART is renge type of SPART and IM_KUNNR is renge of KUNNR.
I am getting a DUMP:
The WHERE condition has an unexpected format.
Error analysis
The current ABAP/4 program attempted to execute an ABAP/4 Open SQL
statement containing a WHERE condition of the form WHERE (itab) or
WHERE ... AND (itab). The part of the WHERE condition specified at
runtime in the internal table itab contains the operator
IN (v1, ..., vn)
in incomplete form.
How to correct the error
If the error occurred in a non-modified SAP program, you may be
able to find a solution in the SAP note system.
If you have access to the note system yourself, use the following
search criteria:
"SAPSQL_IN_ILLEGAL_LIST"
"SAPLZSD_TAB_REFRESH " or "LZSD_TAB_REFRESHU01 "
"Z_SD_REFRESH_AGTABLES"
If you cannot solve the problem yourself, please send the
following documents to SAP:
I would like to know whether "IN" operator is allowed in (itab) of WHERE clause. While testing I changed the "IN" to "=" specifying a suitable value there. It worked. So please let me know if i can give "IN" operator using renge table in the dynamic where clause.
Thanking you,
SuryaHi again, so if you can not use the IN in a dynamic where clause you might be forced to dynamically build the entire select statement, Here is a sample program which may give you some ideas, notice that we are writing the select statement code, putting it in another program and generating the subroutine at runtime, then call this routine. I'm sure that this will help you see what you need to do.

DELETE FROM database table takes more time...
Hi Friends,
The below statement takes more time.
LOOP AT i_final.
DELETE FROM zcisconec WHERE werks = i_final-werks
AND aufnr = i_final-aufnr
AND vornr = i_final-vornr.
ENDLOOP.
Internal table I_FINAL will have more than 80,000 records.
DB Table zcisconec have 4 primary key fields out of 10 fields.
Below 4 fields are primary key fields
WERKS
AUFNR
VORNR
MATNR
Please guide me..How to optimize it?
Regards,
VijiHI,
Check this one ,
put a break point on that delete statement and add another line of code after, like .... CHECK SY-SUBRC = 0. Now got to debug and stop at the DELETE statement, check the number of records in your DB table, now hit F5 to step to the next statement, now go back to SE16 and refresh, do you see the number change? It should.........if you are selecting the data correctly, make sure that you are getting data into the IT_ table.
DELETE zcisconec from i_final.
CALL FUNCTION 'DB_COMMIT'.

Ansari.

Reg:How to delete the column in table control also from database table.
Hi Experts,
Once again thank u all for giving the responses.
one more doubt is how to delete the columns of table control and also the record shold delete from ztable.
With Regards,
Saroja.P.Hi,
If you want to delete the rows in the table control and simultaneously delete it from the database table, then you can implement a 'DELETE' functionality specific to your table control. Have a MARK field (you will find that in the screen attributes of the table control -> give a name for the MARK field, you will find an additional MARK column at the beginning of your table control). You can check whatever rows you want to delete from the table control, call the delete module.
"This portion of code inside the LOOP...ENDLOOP.
IF sy-ucomm eq 'F_DELETE'.
gt_itab2-check = mark. " Store the MARK field status into your internal table's correspoding field 'check'
MODIFY gt_itab INDEX tabcontrol-current_line.
ENDIF.
iF sy-ucomm eq 'DELETE1'.
DELETE gt_itab WHERE check eq 'X'. "Your internal table does not have rows that you want to delete
ENDIF.
Now you can modify your database table using the MODIFY statement.
MODIFY ZDB FROM TABLE gt_itab. -
How to delete a row from database table in facade client
Hi all,
I followed the tutorial in creating a persistence entity from database table, then a session facade. Then I followed the tutorial to create a sample client to test the model. In the session facade, I could use persistEntity method to insert a record to the database. I am just thinking of an extension to the tutorial, i.e., being able to delete the record too. So I created a new method removeEntity in the session facade
public void removeEntity(Object entity) {
entity=em.merge(entity);
em.remove(entity);
em.flush();
and called it in the sample client. It was executed without any error, but the record in the table still exists.
I tried to look around for a solution, but I did not find one. Would anybody here please help out? Many thanks in advance!Hi Frank,
I tried the code snippet, but I got the following exception when executing this code:

Delete entry from Database table
Hi,
I configured one PCR scenerio in SPRO node -> business Packakes/ funtional packages-> Manager self service-> Personal Change request -> Group Change request scenerio.
later I deleted that entry in backend, but still the same entry exist in db table "TWPC_PCR_Groups" .
How can we delete that entry?
thanksHi,
If you just want to delete a single entry from database table then you have to it in debug mode .
go to se11->Give table name->Press F7( ie: display table entries)-> Goto the table contents (CTRLSHIFTF10)->Select the entry you want to delete->Give /H in the command bar ->enter into debug mode-> Give code as DELE -> save it. and press enter. Your entry will be deleted from database.
Hope this helps.. -

Hi,
I want to delete from internal table some regords.
I write code:
delete isrot where bldat < '01.09.2005'.
it doesn't work, what is wrong?
regards,
Joannahi,
you write the statement like....
<b>delete FROM isrot where bldat < '01.09.2005'.</b>
now it will work...
To select the lines that you want to delete using a condition, use the following:
<b>DELETE FROM <target> WHERE <cond> .</b>
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.
follow this link for more information on internal table operation.

Hi,
I am trying to design a page which will delete a particular row from one or more database tables. The jdeveloper version is 11.5 and the database is oracle 10.2 version.
How can I do it?
ThanksHi all, Thanks for the reply..
Actually I am trying to delete one record at a time, from the same table, from which m populating it on the jspx..
That means the list source and the base source are same..which is not possible..
What can be the solution for it ??
I tried to create a separate view object for population on jspx and kept it in list source.. And I am using different view object in base source.. Both view objects refer to the same table..
But it is not working out..the problems are..
The record is getting deleted only for the first time when i run it.. Even after getting deleted from database, the record shows up in the list..
And when i do the same operation one more time in the same session, 1st record in the table is getting updated with the value which i tried to delete..
And I am not using managed bean..

DELETE FROM DATABASE + restored again?
there is a statement
DELETE FROM DATABASE <dbtab> (<ar>) [CLIENT <cli>]

Suppose I have mistakenly deleted from the database

there is a syntax like DELETE FROM DATABASE as you mentioned.
But never ever use that to delete a record in DATABASE TABLE as you cannot recover that data.

Create Trigger to Delete from multiple tables
Hello:
I'm trying to write a trigger which will allow me to delete from multiple records. I have two tables where the record for the same client_id needs to be deleted.
Is it possible to do this? I started writing some code and this is what I have so far:
create or replace trigger app_t1
before delete on <table1> ?? -
for each row
begin
delete from client where clientid = :new.clientid;
delete from key where pk = :newclientid;
end;I'm stuck on the line where I have "before delete on" where I'm supposed to provide a table name. I can only use one table and I need to delete from two.
This trigger is supposed to be used within APEX. In APEX, fields are designated as :P1_clientid where P1 references page 1 of the application. Yet, :P1_clientid is set to the field clientid in the table.
So when I write my trigger, I'm not sure how I'm supposed to set my variables.
Can someone help?
I'm also going to post this into the APEX forum.
Thanks.It's not clear to me if you are just trying to keep two tables in syn or whether you are trying to achieve something else.
A couple of points though:
- In delete database triggers the :new attributes are NULL. You probably mean to use the :old attributes.
- Is there some relationship between the two tables? If so, setting the foreign key to CASCADE DELETE might do the trick for you.
- Another option - better than a database trigger in my opinion - is to just code a procedure that deletes from both tables and call that one from APEX.

Please some one guide me.As I said in the other thread, this really isn't the place to ask questions about a database API unrelated to the Illustrator SDK. You're far more like to find people familliar with your problem on a forum that is dedicated to answering those kinds of questions instead.

I have an ODBC datasource called sui and a table called alarms, i need to write into the column Ack to true when DT equals msgdate and TM equals msgtime, the error returned is Operation must use an updatable query.
I believe the SQL has no problem because there is no SQL syntax error and i'm not updating any resultset returned from select query.
When i delete, i get could not delete from specified table. Anyone has any idea wh'at's wrong?
