Updating Z table according ALV rows

Hi All!
I'm updating several columns automatically in ALV grid rows into Z database (current user name, date and hour). However, when I change only one row, all existed rows on the list are updated.
How can I update only the changed data in ALV?
ps.: it's used REUSE_ALV_GRID_DISPLAY FM.
Points will be rewarded!

Updating multpile tables and multiple rows - JDBC adapter

Hi,
The scenario is like this. i receive an Idoc which has header information and various line items (multiple occurrance of a segment). the hearder details have to be sent to one table, TableA, and all line items has to go to another table, TableB, and for each line item, a new row has to be inserted in TableB.
How can i acheive this using JDBC adapter? how should my data type look like? what are the settings i need to do in adapter config?
Thanks and Regards,
Rashmi

Hi Rashmi,
You can use the following link for the JDBC adapter call :
http://help.sap.com/saphelp_nw04/helpdata/en/ae/d03341771b4c0de10000000a1550b0/frameset.htm
You need to provide the JDBC Driver, Connection,User Name and the password.
The data type structure you can take from the Bhavesh blog:
JDBC Receiver Adapter -- Synchronous Select Step by Step
Since you just need to update the tables, take only the sender side of the blog, i.e. the request part and configure the scenario accordingly.
Regards,
Sanjeev.

here if you have any other fields to be added to the dynamic structure based on your requirement, you can add then and apped them to t_ifc. There is a special handling for unicode conversion- so for the numc and char fields the length is passed in a different mothed.

Updating a table with billion rows

It was an interview question, what's the best way to update a table with 10 billion rows. Give me your suggestions. Thanks in advance.
svk

The best way to answer questions such as this is NOT with a absolute and specific answer. Instead, discuss your strategy for approaching the problem. The first step is to understand your exact requirement. It is surprising how often people
write update statements with an under-qualified where clause. NEVER update a row that does not need to be updated. For example, a statement like:
update mytable set cola = 'ABC' where id in (1, 45, 212);
Assuming id is unique for the table and the specified values exist in the table, we know 3 rows will be updated. Do all of those rows need to be updated? Think about it. If cola is already set to 'ABC' for any of those rows, we could ignore
those rows and make the update more efficient. To do that, you need to add "and cola <> 'ABC' " to the where clause. That is just one example of understanding exactly what you need to do - and doing only that which needs to be done.
Once you understand exactly what you need to do, you need to analyze the impact of the update and identify any potential issues. Updating a lot of rows can take a lot of time and consume large amounts of log and disk space. What else is using
the table? Can you afford to lock the table for the duration of the update? Are there concurrency issues, regardless of whether you update in batches or in one single statement? When using a batch approach, is there an issue if someone runs
a query against the table (i.e., the result is different from that of the same query run after all updates have been completed)? Are you changing something which is included in an index? Are you changing part of the clustered index?
Ultimately, every question you are asked is (or should be) designed to test your problem-solving skills and your skillset. IMO, it is relatively easy to improve your skillset of any particular tool, language, or environment. The other - not so much
and that is why they are more valuable IMO.

Updating database table using ALV Grid class CL_ALV_CHANGED_DATA_PROTOCOL

Hi,
I am trying to use class CL_ALV_CHANGED_DATA_PROTOCOL to update a database table from an ALV grid.
I have used program BCALV_EDIT_04 as an example.
I am able to successfully processed inserted or deleted lines using the attributes
MT_DELETED_ROWS
MT_INSERTED_ROWS
but I also want to process modified lines.
I was just wondering whether anyone out there has some example code for this.
I can see that there are the following attributes available
MT_MOD_CELLS
MP_MOD_ROWS.
I would ideally like to use MP_MOD_ROWS rather than MT_MOD_CELLS but it is not clear to me what type MP_MOD_ROWS is.
If anyone has any example code for this sort of thing, please let me know.
Thanks,
Ruby

hi Ruby,
Yes we can use that *data reference variable *.
It is a variable( something comparable to a pointer ) that points to a int table( table with changed contents )
which ll be created at run-time based on the data type ot the internal table that we pass to the parameter it_outtab of method set_table_for_first_display ...
assign er_data_changed->mp_mod_rows->* to a field-symbol and use it...
Check the below code for example -> method refresh_changed_data

Update SAP tables after ALV report is displayed

Hi All,
I have to display a ALV report using function module REUSE_ALV_GRID_DISPLAY.
After the report is displayed, user can edit some of the flds in the report, and the fields need to updated in the table. How do I proceed to accomplish this.
Is it possible to use FM 'REUSE_ALV_DRID_DISPLAY' to do this or we need to use OOPS ALV to do this.
I searched for this in this forum, but couldnt get.
Thanks in advance,
Ananth

You can use the REUSE_ALV_GRID_DISPLAY. and can make it a changable. You can specify the column to be changable. Once the user enters data into that coloumn the interna table automatically gets populated with the values.
I have done a similar program. However you might need to copy some standard GUI status based on your requirements.
Whats ur mail ID. I can send you the program I have developed.

How to update a table with ALV list reocrds

Dear All,
I have a requirement to display records in ALV list and these records
should get updated in a table and I should also be able to insert new
records in an ALV list.
Could any body please let me know how to do this. This is an urgent requirement.

You can use Table Control instead. Check the following examples in SE38

Selecting multiple rows a table according to rows passed with a table valued parameter

Ive got a table, which looks like this:
CREATE TABLE MyTable (
MyChars CHAR(3) NOT NULL,
MyId INT NOT NULL,
CONSTRAINT PK__MyTable_MyChars_MyId PRIMARY KEY (MyChars, MyId),
CONSTRAINT FK__MyOtherTable_Id_MyTable_MyId FOREIGN KEY (MyId) REFERENCES MyOtherTable (Id)
Records look like i.e.:
Chars | Id
'AAA' | 1
'BBB' | 1
'CCC' | 1
'AAA' | 2
'BBB' | 2
'CCC' | 2
'DDD' | 2
'EEE' | 3
'FFF' | 3
'AAA' | 4
'DDD' | 4
'FFF' | 4
Now I have a SP, which takes a table valued parameter like:
CREATE TYPE dbo.MyTVP AS TABLE ( MyChars CHAR(3) )
This SP should return a set of Ids, which match all the rows of the parameter.
I.e.:
if the TVP contains 'AAA', 'BBB' & 'CCC', i get as result 1 & 2
if the TVP contains 'AAA' & 'FFF', i get as result 4
if the TVP contains 'BBB' & 'EEE', i get an empty result
What my SP is currently doing, is to build a query with string concatination, which is then executed with the EXEC statement. If we take my first example, the built query would look like this:
SELECT DISTINCT t0.MyId
FROM MyTable t0
INNER JOIN MyTable t1 ON t0.MyId = t1.MyId
INNER JOIN MyTable t2 ON t1.MyId = t2.MyId
WHERE t0.MyChars = 'AAA' AND t1.MyChars = 'BBB' AND t2.MyChars = 'CCC'
It works, but I'm not very fond of building the query. Maintaining such things is always a pain. And it also might not be the most efficient and elegant way to do this.
Since I can't think of any other way of doing this, I wanted to ask, if someone of you got an idea, if there is a better way to accomplish this.

Let me give you a "cut and paste" I use in the SQL Server groups:
1) The dangerous, slow kludge is to use dynamic SQL and admit that any random future user is a better programmer than you are. It is used by Newbies who do not understand SQL or even what a compiled language is. A string is a string; it is a scalar value like
any other parameter; it is not code. Again, this is not just an SQL problem; this is a basic misunderstanding of programming principles.
2) Passing a list of parameters to a stored procedure can be done by putting them into a string with a separator. I like to use the traditional comma. Let's assume that you have a whole table full of such parameter lists:
CREATE TABLE InputStrings
(keycol CHAR(10) NOT NULL PRIMARY KEY,
input_string VARCHAR(255) NOT NULL);
INSERT INTO InputStrings
VALUES ('first', '12,34,567,896'),
('second', '312,534,997,896'),
etc.
This will be the table that gets the outputs, in the form of the original key column and one parameter per row.
It makes life easier if the lists in the input strings start and end with a comma. You will need a table of sequential numbers -- a standard SQL programming trick, Now, the query,
CREATE VIEW ParmList (keycol, place, parm)
AS
SELECT keycol,
COUNT(S2.seq), -- reverse order
CAST (SUBSTRING (I1.input_string
FROM S1.seq
FOR MIN(S2.seq) - S1.seq -1)
AS INTEGER)
FROM InputStrings AS I1, Series AS S1, Series AS S2
WHERE SUBSTRING (',' + I1.input_string + ',', S1.seq, 1) = ','
AND SUBSTRING (',' + I1.input_string + ',', S2.seq, 1) = ','
AND S1.seq < S2.seq
GROUP BY I1.keycol, I1.input_string, S1.seq;
The S1 and S2 copies of Series are used to locate bracketing pairs of commas, and the entire set of substrings located between them is extracted and cast as integers in one non-procedural step. The trick is to be sure that the right hand comma of the bracketing
pair is the closest one to the first comma. The relative position of each element in the list is given by the value of "place", but it does a count down so you can plan horizontal placement in columns.
This might be faster now:
WITH Commas(keycol, comma_seq, comma_place)
AS
(SELECT I1.keycol, S1.seq,
ROW_NUMBER() OVER (PARTITION BY I1.keycol ORDER BY S1.seq)
FROM InputStrings AS I1, Series AS S1
WHERE SUBSTRING (',' || I1.input_string || ','
FROM S1.seq
FOR 1) = ','
AND S1.seq <= CHARLENGTH (I1.input_string))
SELECT SUBSTRING(',' || I1.input_string || ','
FROM C1.comma_place +1
FOR C2.comma_place - C1.comma_place - 1)
FROM Commas AS C1, Commas AS C2
WHERE C2.comma_seq = C1.comma_seq + 1
AND C1.keycol = C2.keycol;
The idea is to get all the positions of the commas in the CTE and then use (n, n+1) pairs of positions to locate substrings. The hope is that the ROW_NUMBER() is faster than the GROUP BY in the first attempt. Since it is materialized before the body of
the query (in theory), there are opportunities for parallelism indexing and other things to speed up the works.
Hey, I can write kludges with the best of them, but I don't. You need to at the very least write a routine to clean out blanks, handle double commas and non-numerics in the strings, take care of floating point and decimal notation, etc. Basically, you must
write part of a compiler in SQL. Yeeeech! Or decide that you do not want to have data integrity, which is what most Newbies do in practice altho they do not know it.
A procedural loop is even worse. You have no error checking, no ability to pass local variables or expressions, etc.
CREATE PROCEDURE HomemadeParser(@input_string VARCHAR(8000))
AS
BEGIN
DECLARE @comma_position INTEGER;
CREATE TABLE #Slices
(slice_value INTEGER);
SET @input_string = @input_string + ','; --add sentinel comma
SET @comma_position = CHARINDEX(',', @input_string);
WHILE @comma_position > 1
BEGIN
INSERT INTO #Slices (slice_value)
VALUES(CAST(LEFT(@input_string, (@comma_position - 1)) AS INTEGER));
SET @input_string = RIGHT(@input_string, LEN(@input_string)-@comma_position)
SET @comma_position = CHARINDEX(',', @input_string)
END;
END;

Do this with a long parameter list. You can pass up to 2000+ parameters in T-SQL, which is more than you probably will ever need. The compiler will do all that error checking that the query version and the procedural code simply do not have unless you write
a full parser with the standard error codes. You can now pass local variables to your procedure; you can pass other data types and get automatic conversions, etc. In short, this is just good software engineering.
CREATE PROCEDURE LongList
(@p1 INTEGER = NULL,
@p2 INTEGER = NULL,
@p3 INTEGER = NULL,
@p4 INTEGER = NULL,
@p5 INTEGER = NULL)
x IN (SELECT parm
FROM (VALUES (@p1), (@p2), (@p3), (@p4), (@p5)) AS X(parm)
WHERE parm IS NOT NULL;
You get all the advantages of the real compiler and can do all kinds of things with the values.

[ADF BC | ADF Faces] Updating a table with values updated in transaction

Summary: A table is based on a view with a bind variable. Based on some action, I update rows in the view so that they no longer satisfy the query. How do I update the table to reflect this?
I have an ADF Faces page with a multi-select table component on it, mapped to an ADF Business Components view object. The view object has a bind variable (:Status), which is used in the query to only retrieve rows with a specific status.
The user selects rows in the table that should have their status changed, and then hits a button to perform the action. In the backing bean for the page, the button click is processed and the selected rows are updated to a different status. At this point the transaction is not committed.
Changing the status of these rows now means that they no longer match the where clause of the view object, yet they still appear in the table.
My question is, how can I update the table so that rows which don't match the where clause are removed?
This is a simplified version of the problem I am working on - this needs to work when rows that aren't in the table are being updated so that they now MATCH the where clause and rows may also be added or completely removed.

Quite an interesting little problem....
I have created a simple test case to illustrate your scenario - perhaps Steve M could comment...
My scenario:
1). create an EO based on the HR.EMPLOYEES table
2). create an updatable VO based upon the aforementioned EO. Add "COMMISSION_PCT IS NULL" to the where clause.
3). Add the VO to an app module as usual.
4). Create an ADF Faces page by dropping the VO from the data control as an ADF table. Show only first name, last name, and commission pct.
5). Add a command button to the page so I can call various code from the backing bean.
Now, when I update the commision for the first record to ".1" and press the submit button (the one in the table actions facet), the update "takes" - I assume that it's just in the EO cache at this point. The record still shows on the screen, even though it no longer meets the where clause criteria.
When I add some code to the command button (#5) to perform a commit - the record STILL shows on the screen after committing to the DB. I can make the record disappear by either (in the same backing-bean method that does the commit)
a). Re-execute the iterator after the commit
b). Call "clearVOCaches" on the application module (forces the iterator to re-execute)
I even tried programmatically adding the where clause back in (via addWhereClause) and re-executing the iterator - no go. I suspect that the only way to do this would be to post the changes to the DB (without committing them) and then re-execute the query. This, however, would be a killer from a scalability perspective.

Listening to change in a row of a table a and update a table in a diferent Database

With Service Broker?
Without Service Broker, you would do:
UPDATE targettbl
SET col1 = b.col1,
   col2 = b.col2,
FROM   targettbl a
JOIN   srctbl b ON a.keycol1 = b.keycol1
   AND a.keycol2 = b.keycol2
It is important that a row in targettbl maps to at most at one row in srctbl, or else the result will not be predictable.

Updating a table to add a count of duplicates to each row

I wondered if it is possible to do the following using a single SQL statement?
To simplify my example, I have a table such as:
create table tempftm_dups (product_id number, product_name varchar2(10), duplicate_count number);
insert into tempftm_dups (product_id, product_name)
values (1, 'CD');
insert into tempftm_dups (product_id, product_name)
values (2, 'BOOK');
insert into tempftm_dups (product_id, product_name)
values (3, 'DVD');
insert into tempftm_dups (product_id, product_name)
values (4, 'BOOK');
This gives the result as below:
SQL> select * from tempftm_dups;
PRODUCT_ID PRODUCT_NA DUPLICATE_COUNT
1 CD
2 BOOK
3 DVD
4 BOOK
I would like to update the table so the the duplicate_count column shows the number of times the PRODUCT_NAME is duplicated within the table. (ie. rows 2 and 4 would show a DUPLICATE_COUNT = 2, whereas rows 1 and 3 would show DUPLICATE_COUNT = 1).

Something like this should do the trick.
update tempftm_dups      t
   set t.duplicate_count = (
        with w_counter as (
                select td.product_name
                     , count(*)           cnt
                  from tempftm_dups       td
                 group by td.product_name
        select wc.cnt
          from tempftm_dups       td
             , w_counter          wc
         where td.product_name = wc.product_name
         and   td.product_id    = t.product_id
        )Hope this helps,
Gregory

How to update a table that has hundred thousand rows?

Hi all !
I detect that I did wrong with column SHAPE (in GRAG table ) ,namely at Gtype : 3003
(MDSYS.SDO_GEOMETRY(3003,50632625,'null',MDSYS.SDO_ELEM_INFO_ARRAY(1,5,1,1,2,1),MDSYS.SDO_ORDINATE_ARRAY(276.2339,-179.7433,0,276.2498,-179.7361, 0 ))
And I need to update value Gtype :3003 to 3002 .
My problem is I don't know how to implement it because GRAG table has 30000 rows . I cannot update every row manually .
Do you have any advice ?

AFAIK oracle11g cannot simply update SDO_GEOMETRY.
so you have to create new SDO_GEOMETRY with all but one old values.
try to modify this (I wrote it once to circumvent the cannot modify SDO_GEOMETRY problem):
-- clones a geometry but with different values
-- we can "alter" the SRID
-- note: oracle 11g cannot modify geometries
function alter_geometry(p_geo sdo_geometry, p_srid number default null)
return sdo_geometry is
v_result sdo_geometry;
v_srid number;
begin
if p_srid is null then
v_srid := p_geo.SDO_SRID;
else
v_srid := p_srid;
end if;
v_result := sdo_geometry(p_geo.SDO_GTYPE,
v_srid,
p_geo.SDO_POINT,
p_geo.SDO_ELEM_INFO,
p_geo.SDO_ORDINATES);
return v_result;
end alter_geometry;
--then do an update like
--test before with an create table as select
update crack c set c.shape = alter_geometry(shape, ...)

Updating A Table in a for each row trigger

I have a trigger,
create or replace trigger ins_ibpm_temp_trig
after update of ethic_dt on ethics_approval_info for each row
My issue is that I need to update the ethics_approval_info for each record based on the ethics date that was updated. I am getting the error
ORA-04091: table ORACLETEST.ETHICS_APPROVAL_INFO is mutating, trigger/function may not see it.
So the issue here of course is that I am trying to update a table, that is already in the middle of updating. Is there any way to get around this?

Read only set for few rows of a column in a table (not ALV)

Hi Gurus,
I have a table with multiple rows and columns. Under a particular column, I have to make few rows as read only, few rows as editable based on a coondition. How can I achieve this. I know how to make the whole column as editable or read only. But I'm not able to achieve few rows in a particular column as editable and few read only. Please give me more detail code.
Appreciate your help.
Regards,
David.

Hello,
That you can achieve by creating an attribute isReadOnly of type WDY_BOOLEAN in the context node that you bind to the TABLE. And set isReadOnly attribute based on your condition whether to set readonly or editable for all the context elements.
And in the layout view, for the column which has to be made readOnly or editable, bind the property readOnly to the context attribute isReadOnly.
When you run application, you will see the column as readOnly if the attribute was set to true and editable if it was set to false.
Hope this helps!
Regards,
Srilatha
