Updating a field in a record

hello,
when i update a database field in a record in my form without using a pre-update trigger, just changing the value and commiting the form.
:deleted:= 1 (deleted is the database item in my database datablock)
commit_form;(a question to save the form)
the record is not updated, why?

Check the following properties are correct in that Item property
Database Item = TRUE
Update allowed = TRUE

How to update specific fields of a db table using MODIFY

Hi all.
I understand that MODIFY allows us to insert a record into the database if the a record with the same key is not there. If a record is there, it would update that record.
However, when the record is there, could i update SPECIFIC fields of the record, instead of updating ALL fields of the record?

Yes, you can with exception that you can not modify primary key values.
Here are the details about MODIFY db table command with examples
MODIFY - Change a database table
Variants:
MODIFY dbtab. or   MODIFY *dbtab. or
MODIFY (dbtabname) ... .
MODIFY dbtab FROM TABLE itab. or   MODIFY (dbtabname) FROM TABLE itab.
MODIFY dbtab VERSION vers. or   MODIFY *dbtab VERSION vers.
Effect
Inserts new lines or updates existing lines in a database table (s. relational database). If a line with the specified primary key already exists, an UPDATE is executed. Otherwise, an INSERT is performed. You can specify the name of the database table either in the program itself in the form MODIFY dbtab ... or at runtime as the contents of the field dbtabname in the form MODIFY (dbtabname) ... . In both cases, the database table must be defined in the ABAP Dictionary. If the program contains the name of the database table, it must also have a corresponding TABLES statement. Normally, records are inserted or updated only in the current client. Data can only be inserted or updated using a view, if the view refers to a single table and was created in the ABAP Dictionary with the maintenance status "No restriction".
MODIFY belongs to the Open SQL command set.
When the statement has been executed, the system field SY-DBCNT contains the number of edited lines.
The Return code is set as follows:
SY-SUBRC = 0:
    All lines were successfully inserted or updated.
SY-SUBRC = 4:
    One or more lines could not be inserted or updated.
Notes
   1. You cannot modify a line if there is already a line in the table with identical key field values in a UNIQUE index.
   2. Automatic definition of INSERT and UPDATE is expensive. You should therefore use MODIFY only if you cannot define the INSERT and UPDATE cases yourself in the program.
   3. Since the MODIFY statement does not perform authority checks, you have to program them yourself.
   4. Adding or changing lines with the MODIFY command is only completed after a database commit (see LUW) has been performed. Before the database commit has been performed, any database changes can be reversed with a database rollback (see Programming transactions).
   5. Synchronization of simultanous accesses by several users to the same set of data cannot be exclusively achieved with the lock mechanism of the database system. In several cases, you are recommended to use the SAP lock mechanism.
Variant 1
MODIFY dbtab. or
MODIFY *dbtab. or
MODIFY (dbtabname) ... .
Extras:
... FROM wa
... CLIENT SPECIFIED
See Cannot Use Short Forms and
Cannot Use *Work Areas.
Effect
Inserts a new line or updates an existing line in a database table. If you specify the name of the database table yourself, the primary key for identifying the line to be inserted or updated and the relevant values are taken from the table work area dbtab or *dbtab (see TABLES). If you declare the name of the database table explicitly, the program must also contain a corresponding TABLES statement. If the name of the database table is not determined until runtime, you need to use the addition ... FROM wa.
Example
Insert or change data of the customer Robinson in the current client:
TABLES SCUSTOM.
SCUSTOM-ID        = '12400177'.
SCUSTOM-NAME      = 'Robinson'.
SCUSTOM-POSTCODE = '69542'.
SCUSTOM-CITY      = 'Heidelberg'.
SCUSTOM-CUSTTYPE = 'P'.
SCUSTOM-DISCOUNT = '003'.
SCUSTOM-TELEPHONE = '06201/44889'.
MODIFY SCUSTOM.
Addition 1
... FROM wa
Effect
The values for the line to be inserted or updated are not taken from the table work area dbtab, but from the explicitly specified work area wa. When doing this, the data is read from left to right according to the structure of the table work area dbtab (see TABLES). Since the structure of wa is not taken into account, the work area wa must be at least as wide (see DATA) as the table work area dbtab and the alignment of the work area wa must correspond to the alignment of the table work area. Otherwise, a runtime error occurs.
Note
If a work area is not explicitly specified, the values for the line to be inserted or updated are also taken from the table work area dbtab if the statement is in a FORM or FUNCTION where the table work area is stored in a formal parameter or local variable of the same name.
Addition 2
... CLIENT SPECIFIED
Effect
Switches off automatic client handling. This allows you to edit data across all clients even when dealing with client-specific tables. The client field is treated like a normal table field that can be programmed to accept values in the table work area dbtab or *dbtab where the line to be edited occurs.
The addition CLIENT SPECIFIED must be specified immediately after the name of the database table.
Variant 2
MODIFY dbtab FROM TABLE itab.or
MODIFY (dbtabname) FROM TABLE itab.
Addition:
... CLIENT SPECIFIED
Effect
Mass modify: Inserts new lines or updates existing lines of a database table. The primary keys for identifying the lines to be inserted or updated and the relevant values are taken from the internal table itab. The lines of the internal table itab must satisfy the same conditions as the work area wa in addition 1 to variant 1.
Note
If the internal table itab is empty, SY-SUBRC and SY-DBCNT are set to 0.
Addition
... CLIENT SPECIFIED
Effect
As for variant 1.
Variant 3
MODIFY dbtab VERSION vers. or
MODIFY *dbtab VERSION vers.
See Cannot Use the VERSION Addition.
Note
This variant is obsolete.
Effect
Inserts a new line or updates an existing line in a database table, the name of which is taken from the field vers at runtime. If no line exists with the specified primary key, an INSERT is executed. Otherwise, an UPDATE is performed. The database table must be defined in the ABAP/4 Dictionary and its name must conform to the naming conventions for R/2 ATAB tables. These stipulate that the name must begin with 'T' and may contain up to four further characters. The field vers must contain the table name without the leading 'T'. Only lines in the current client are inserted or updated. The line to be inserted is taken from the statically specified table work area dbtab or *dbtab.
SY-SUBRC is set to 0 if the line is successfully inserted or updated. SY-SUBRC <> 0 is not possible since any other result causes a runtime error.
Hope this helps.

Updating field when new records saved.

Hi,
I was wondering if there are any suggestions on updating a picklist field when a new record is saved (as field updates only work for modified records).
We recently created a custom Probability % field that is tied to both the Sales Stage and another custom picklist field called "Business Type" (has two options - New or Existing). The Probability % field is updated based on a simple workflow that says if Sales Stage = x and Business Type = y, then Probability % = z.
For example, if the Sales Stage is = to "Validation" and the Business Type is = to "New", the Prob. % will be 5. If the Sales Stage is = to "Validation" and the Business Type is = to "Existing", the Prob. % will be 10... (just so you get the idea).
Since the workflow is tied to modified records, the new records keep missing the Probability % field.
Any suggestions on how we can get those newly created records have an updated Prob. % field would be helpful.
Thanks in advance!

Thanks for the response, Min.
1) I've thought about the post default value, but the problem we encounter is that the user might not create an Opportunity in the very first sales stage- is there a way to place a default in the Prob. % field depending on the sales stage the record is created with?
2) I thought fields could only be updated when modified records saved - it isn't an option with the "new record is saved". Is there a workaround? I'm still quite new at this, so any help on how I can create a workaround would be great!
Thanks again.

Automatically update a 'Last Updated By' field when changes are made a database record.

Basically I'm building a database app using mySQL and PHP.
I'm from a design background, rather than a techie one, so I'm far
more comfortable using the DW and phpMyAdmin parts, but less so
with any code.
We want to have a 'Last Updated By' field that automatically
populates with whoever created or last edited a record.
What's the best way of achieving this?
I've looked at some mySQL stuff, but all looks a bit over my
head to be honest. Have a table of Users in phpMyAdmin - not one as
part of the database, but under privileges - so where 'root' is,
plus another couple I've added.
In the web directory, I just have a standard connection file
that looks like :
<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_connDevelopments = "localhost";
$database_connDevelopments = "developments";
$username_connDevelopments = "root";
$password_connDevelopments = "password";
$connDevelopments =
mysql_pconnect($hostname_connDevelopments,
$username_connDevelopments, $password_connDevelopments) or
trigger_error(mysql_error(),E_USER_ERROR);
?>
But how do I do it so that people log in to the database?
Alternatively, can I just use DW's log in (ie log in to
particular pages, rather than users log in to the database, using
database privileges?
And from there have a hidden field in my insert and update
pages that's set to the current user, and that value can then be
inserted in the table?
Any help or pointers with this greatly appreciated.
Cheers.

Thanks David. That sounds about right - the last app I did
was an online photo library, and used the Log In stuff for that.
With this one, we want to track changes, as we'll follow the
progress of the developments from early info right through to
completion - hence last updated, and last updated by fields.
So I figured it should be do-able as an extension of the log
in stuff, ie pass the stored current user somewhere.
Regarding security - this is just a local app running on an
internal server, rather than out there in the wild.
To test it out, I've added a 'LastUpdatedBy' field to my
other app, and added in a hidden field in my update page :
<input name="LastUpdatedBy" type="hidden"
id="LastUpdatedBy" value="$_SESSION['MM_Username']">
I have the code that does the inserting :
if ((isset($_POST["MM_update"])) &&
($_POST["MM_update"] == "form1")) {
$updateSQL = sprintf("UPDATE Photos SET Link_ID=%s,
Title=%s, Rights=%s, Rights_Details=%s, Credit=%s, Width=%s,
Height=%s, Year=%s, Supplier=%s, Photo_File=%s, Orientation=%s,
Admin=%s, Region=%s, Country=%s, Easting=%s, Northing=%s,
LastUpdatedBy=%s WHERE Photo_ID=%s",
GetSQLValueString($_POST['Link_ID'], "text"),
GetSQLValueString($_POST['Title'], "text"),
GetSQLValueString($_POST['Rights'], "text"),
GetSQLValueString($_POST['Rights_Details'], "text"),
GetSQLValueString($_POST['Credit'], "text"),
GetSQLValueString($_POST['Width'], "text"),
GetSQLValueString($_POST['Height'], "text"),
GetSQLValueString($_POST['Year'], "text"),
GetSQLValueString($_POST['Supplier'], "text"),
GetSQLValueString($_POST['Photo_File'], "text"),
GetSQLValueString($_POST['Orientation'], "text"),
GetSQLValueString($_POST['Admin'], "text"),
GetSQLValueString($_POST['Region'], "text"),
GetSQLValueString($_POST['Country'], "text"),
GetSQLValueString($_POST['Easting'], "text"),
GetSQLValueString($_POST['Northing'], "text"),
GetSQLValueString($_POST['textfield'], "int"),
GetSQLValueString($_POST['LastUpdatedBy'], "text"));
The bits in bold I've added for the LastUpdatedBy - but no
joy - that's entering $_SESSION['MM_username'] into the table.
What should the syntax be?

Master Detail Form - How 2 update a field in the Detail form using a query?

Hello,
I have a master detail form with, each master record having a fixed(6) number of detail records. One of the fields in the detail record is the PART_DESCRIPTION field. I am trying to update this field by querying Table_X. TABLE_X is in the format of (desciption id, description). Description id runs from 1 to 6.
When the form displays, the PART_DESCRIPTION field for the 6 detail records needs to be automatically populated with the six values of description stored in Table_X. How can this be done?
Tried using session storage objects, but made no headway.
Would greatly appreciate pointers on how to go about doing this.
Thanks.

How can I update data fields in a merged document ?

Hi,
I'm looking for a way to update the values of data fields in a merged document with a script just as you can do with the user interface.
I don't find any method like "updateDataFields ()" in the DataMerge object.
Si I try to invoke the menu action "Update Data Fields", but it fails. The script error message is: "Error 53762, the script is not active." On the contrary, the action works if I use the interface.
Can anyone help me?
Thanks in advance,

Reg "created by" and "updated by" fields in Data Manager

Hi,
I just want to know if we have any solution for the "Create By" and "Update By" issue in data manager. Because in my system i have two users. The 1st user created the record and later if the 2nd user edits any field then only the "Update By" field should show the 2nd user name but as of now now it updates both the "Create By" and "Update By" by the 2nd user name.
Expecting your valuable inputs on this.
Thanks in advance !!

Hi Arumugam,
goto Console and check the "Selected Fields" property of your "Create By" fields. You should choose a field that does not change at all if some updates the record. A good choice is a Auto ID that is created only once when the record is created. So you can ensure that your Create User will not change if anyone is updating the record later on.

Start routine to update some fields of a ODS based on the another ODS

Hi I know i have to do abap coding at the start routine to update a ODS based on another ODS. I have tried doing the code for quite some time now and i have not been successful. I think I havenu2019t followed the definition required for this routine.
I have 2 ODS, ODS1 has 3 key fields and ODS2 has 1 key field
I have to map the ODS based on a 1:3 relation.
I am writing this start routine for the update rules from ODS2 to ODS1.
The logic is if the key field of ODS2 is equal to either Key field 1 or Key field 2 or Key field 3 of ODS1 then that record from ODS2 has to be updated to the corresponding matching record of ODS1, else no update. The 3 key fields of ODS1 have different character length and character types and the key field of ODS2 has a different character length and type when compared to the any of the key fields of ODS2 can match any of those.
Like key field 1 of ODS1 has length 10. Key field 2 of ODS1 has length 10 and key field 3 of ODS1 has length 20 and all these fields are not alpha converted, but the key field of ODS2 has length 60 and it is alpha converted.
Can anyone please help me in this code.
My Code is as below.
ITAB1-T_BOL = DATA_PACKAGE-/BIC/ZLBOL.
***********NISTEVO SELECT******************************
SELECT /BIC/ZLBOL FROM /BIC/AWLONST0100 INTO ITAB1-T_BOL
              WHERE /BIC/ZLBOL = ITAB1-T_BOL .

    SELECT /BIC/ZLRDELNU /BIC/ZLRSHIPNU /BIC/ZLREXTID
              FROM /BIC/AWLOR3O0400

              WHERE
              /BIC/ZLRDELNU = ITAB1-T_BOL OR
               /BIC/ZLRSHIPNU = ITAB1-T_BOL OR
               /BIC/ZLREXTID = ITAB1-T_BOL .
      SORT ITAB1 BY T_DELNU T_SHIPNU T_EXTID .
      LOOP AT DATA_PACKAGE.
        READ TABLE ITAB1 WITH KEY T_DELNU = DATA_PACKAGE-/BIC/ZLBOL.
        IF SY-SUBRC = 0.
          EXIT.
        ENDIF.
        READ TABLE ITAB1 WITH KEY T_SHIPNU = DATA_PACKAGE-/BIC/ZLBOL.
        IF SY-SUBRC = 0.
          EXIT.
        ENDIF.
        READ TABLE ITAB1 WITH KEY T_EXTID = DATA_PACKAGE-/BIC/ZLBOL.
        IF SY-SUBRC = 0.
          EXIT.
        ENDIF.
        DELETE DATA_PACKAGE .
      ENDLOOP.
    ENDSELECT.
ENDSELECT.
Points will be awarded.

Can you try below logic :
Below is not code it needs to be manipulated as per requirement.
ODS2 ---> ODS1
SELECT <key fields of ODS1>
FROM /BIC/A<ODS1>00
INTO ITAB
FOR ALL ENTRIES IN DATA_PACKAGE
WHERE
keyfield1 = data_package-key1
or
keyfield2 = data_package-key2
or
keyfield3 = data_package-key3
**Now itab has all entries which neednot be deleted from data_package.****
if sy-subrc=0.
***Check Itab and delete only those records not present in itab from data_package****
endif.
Hope this helps.

Help needed in PL/SQL for updating the column for multiple records

Hi,
I am new to PL/SQL and need some help. What is the most effiecient way to update some field in a table as I may need to update thousands of records. I have a coulmn groupid can have multiple records tied to it. All the records attached to some groupid have a priority field also.
How can I update the prorityfield value for all the groupids in a profiecient way. Here is a sample data
GroupId     Priority
1            1
1            2
1            3
1            4
1            5
2            1
2            2
2            3
3            1Here I have three groups 1, 2, 3. Now if any group contains only one record the priority remains same e.g. groupid=3 on top. If any group contains more than one record e.g. groupid=1 & 2 I want to re-arrange the priority fields e.g. If I want to update groupid=1 now if I change the priority of 2 to 5 (make it the last) I want to rearrange the remaing records priority i.e. if 2 becomes 5 as I have 5 rows for groupid=1 then 5 becomes 4, 4 becomes 3, 3 becomes 2 and 1 remains the same.
Same wya if I want to make the priority 1 to 3 for groupid=2 then need 2 to become 1 and 3 to become 2 etc....
Any help is appreciated.
Thanks

Hi,
You don't need PL/SQL to do this (though you can put the following in PL/SQL if you want to):
UPDATE     table_x
SET     priority = CASE
               WHEN groupid     = 1
               AND   priority = 2
                    THEN 5
               WHEN groupod     = 1
               AND   priority     BETWEEN 3 AND 5
                    THEN priority - 1
               WHEN groupid = 2
               THEN
                    CASE
                         WHEN prioity = 1
                         THEN 3
                         ELSE priority - 1
                    END
             END
WHERE     groupId          IN (1, 2)
AND     (     priority     BETWEEN 2 AND 5
     OR     groupid          = 2
     );There are lots of different techniques that can reduce your coidng: for example, the nested CASE statement used for groupid=2 above.
You could do several smaller UPDATEs (for example, one just for groupid=1). Execution will be slower, but coding and testing will be faster.
You could make the "magic numbers" 2 (for groupid=1) and 1 (for groupid=2) variables, even outside of PL/SQL.
If you need more help, post the information that Satyaki requested.

CSV upload and update table fields

Hi,
Is there any way to update any field of the underlying table from HTMLDB while importing the CSV file?For e.g, if there are XYZ table have 200 ermployee where empno is primary key.
Once we upload the data from CSV its fine.Now after 2 weeks i need to update the sal and ename corresponding to the previous 100 employees only.So now when i trying to update the data a unique constraints violation occurs since the empno have already present so my concern is that -- how to get out of this problem specially when updation of huge no. of records needed and also no updation required for some records already present?Do the CSV update be helpful on that circumstances?
One thing we can do that we can track down the list of 100 employee whose information going to be updated.Put those info in excel and add rest 100 emplyee to that excel and again doing the CSV upload ?
This is a huge issue and not only the tedious task but also errorprone and that task will be increased with the amount of data increasing in the table.
Please anyone can suggest ?
Regards,
ROSY.

The best way to solve your problem is next way.
1º) Save the file with the data to import like a BLOV ITEM.
Ok it can be done. CSV placed on BLOB data field.2º) Make a procedure to manage this BLOV item that can be fired by user pushing a buttom. (you can do it easy from HTMLDB).
how to manage ? What need to be fire to push the CSV to the target table with the actual field population ?3º) Into this procedure insert the records freely and dont worry for anything more. (maybe you can be worry about duplicate records is so, only, into this same procedure make any pl/sql lines to be sure record is not duplicate before insert)
? ? ? If the data already exist it should be needed to truncate before insert that is not my reqr rather the existing data should be updated based on PK if any chages occurs in the CSV fo that data.4º) after you are sure the insert work properly and if you need any other treatment to record, with a trigger in the table or calling any other procedure from the same trigger make the traeataments that you need.
that can be done highly .......before insert trigger.Remember. Dont put any commit.
sure.......5º) Go down from horse. Dont take coffe or Tea in exceed. And remember all we are the same, people that only want go to eat with childs in week-end.
i m in land no way to go down........nothing i take ya eat & eat much ....but this is not the right place for making comments about Weekend....Regards and good luck.
anyway embargo starts...........enjoy Cheers...........Wish u All Hp XMas...

How does the Updated by Field Work....

Hi Experts,
Can anyone help on how the *Updated By* field values are populated, specially when the values are updated through a Workflow.
I read the following in the MDM Documentation.
If trigger action is Record Add, Record Update, or Record Import for a workflow. The [System] is the creator and launcher of the job but is not a real user.
This is even true if the Owner of the workflow is the Admin.
After our server migration was done, instead of showing [System] as the Updated By it now shows the Admin.
What could be the reason for this. Do i need to contact SAP or is there something that needs to be done at the respository level to get the Updated By field to work as expected.
Regards,
Aditya.

Hi Aditya,
As far as i am concerned, this is not true. Field Updated by type of User Stamp should only show user's which are there in User's table of MDM console under node Admin-->Users. When we don't have any User of repository with name System, there is no point it will show you user System for field Updated by.
Query 1: Can you please confirm, do you have this User "system" available in your repository under node admin-->Users in MDM console ?
Query 2: Also, After our server migration was done, instead of showing System as the Updated By it now shows the Admin.
I seriously have doubt on this. Can you please check do you have really user System for existing records too? I mean you can do Free-form search for field Updated by with value system. I am sure even for existing records (whether in before server migration or in existing) you will not get single record with field updated by "system" . Can you please confirm on this ?
May be I am wrong, so kindly revert with your findings and confirm above both queries..?

Update multiple fields using select query efficiently – 9i

I need to populate a table called prop_charact used for synching data to a legacy system.
Prop_charact has fields that are found in a few other tables (no one field is found in more than one table outside of prop_charact). I want to pull the data from the corresponding fields in the source tables and put it into prop_charact. I only want to populate prop_charact with records that have been updated, but want to pull all fields for those records (whether or not that field has been updated). I am getting the list of updated records from a transaction history table.
After getting that list, I was not sure what to do with it.
I put what I want to do in terms of strictly SQL. I am thinking there are more efficient (less system resources) ways of doing this, but I am not sure what to pursue. I can use PL/SQL, but please keep in mind I am limited to using version 9i. Anyone have any hints about what I should look into using instead of just thes particular SQL statements?
insert into eval.prop_charact (parcelno, propertyid)
select distinct p.parcelno, p.propertyid
from eval.transaction_history tr,
admin.properties p
where tr.propertyid = p.propertyid
and trim(tr.tablename) in ('PROPERTIES', 'PROPERTYCHARACTERISTICS','EQID','NEWCHARACTERISTICS','DIMENSIONS', 'NON_RESIDENTIALS')
and trim(tr.fieldname) in ('BLDGCODE', 'CATCODE', 'UNFINISHED', 'TOPOGRAPHY', 'GARAGETYPE', 'GARAGESPACES', 'OPENSPACES',
'VIEW', 'GENERALCONSTRUCTION', 'YEARBUILT', 'ESTIMATEDYEAR', 'TOTALROOMS', 'TOTALBEDROOMS',
'BASEMENTTYPE', 'NUMBEROFFIREPLACES', 'HEAT', 'CENTRALAIR','CONDITION','SITE_TYPE','TOTALDWELLINGAREA',
'PLOTFRONT','PLOTDEPTH','PLOTSQFT','SHAPE','STORIES','FULLBATHROOMS','PARTBATHROOMS','MULTIPLE_BLDGS')
and tr.trans_date >= to_date('01-01-2010', 'MM/DD/YYYY')
and tr.trans_date < sysdate
order by p.parcelno;

The following example may be of help.
SQL> create table mytable(col1 number(1),
2 col2 date);
Table created.
SQL> insert into mytable values(1,sysdate);
1 row created.
SQL> select * from mytable;
      COL1 COL2
         1 20-AUG-04
SQL> update mytable
2 set (col1,col2) = (select 2, sysdate-1 from dual);
1 row updated.
SQL> select * from mytable;
      COL1 COL2

Ideal way to update a field in a table

Hi All,
We need to update a field in a table which have some 8 million records.
The value of the field needs to be updated in all the above mentioned records.
Now, we have an input file with all the primary key fields and the field to be updated.
Can any one suggest the ideal way to update the field.
1.     Updating the database for each record.
Loop at itab.
Update.
Endloop.
2.     Updating the database with a set of 100 records.
We are planning to schedule the job in the background.
Thanks for your help.
Regards,
Krishna

Hi,
be very carefull with the update, ´cause you can damage 8 million records !!
You better use instruction Update for this:
update mytable set field = value where conditions.
Try to use all key fields in the conditions and never use something like
update mytable set: field1 = value1
                    field2 = value2
                    field3 = value3 where conditions.
The loop in your case 1 is not absolutely necessary, ´cause you update a whole bunch of records at once with the conditions in Update.
Test the changes in the development system before you do it in production
