I have an UPDATE statement in ABAP which looks like :
UPDATE zicstt099 FROM TABLE lt_zicstt099
The Update is failing every time with sy-subrc eq 4.
The database Table ZICSTT099 has three primary keys : WEB_USER_ID & EMAIL_ID along with MANDT field.
I am trying to change the EMAIL_ID value but the same is not getting Updated.
Kindly help.
You cannot change primary key fields using the UPDATE <target> FROM <wa>. and UPDATE <target> FROM TABLE <itab>. statements, since they use the primary key to lookup the record(s) they must update.
Use the UPDATE <target> SET <set1> ... WHERE ... statement instead.
You can find the specifics over here:
https://help.sap.com/doc/abapdocu_753_index_htm/7.53/en-US/abapupdate_source.htm#!ABAP_ALTERNATIVE_1#1#
After using UPDATE, if sy-subrc = 4, then at least one line was not able to be changed, either because no appropriate line was found, or because the change would generate a line that leads to double entries in the primary key or a unique secondary index in the database table.
The statement UPDATE sets sy-dbcnt to the number of changed lines.
You can't 'change' key fields in data bases.
You may delete your original entry and insert a new one with another key. But you can't change a key field. (I can't check actual, if modify is doing it on it's own.
If you have to change a key field, you should think about your DB-definition.

Can we update primary key values of a table?
hi i tried to create the table with your keys as mentioned , I advice you to use the below syntax
update lt_zicstt099 set email_id = 'some value' where WEB_USER_ID = 'some web id'.
To check if the table is updated you can use sy-dbcnt to know the number of lines updated.
if still you face issues please comment below

I am getting the following error. Could you please help me?
Msg 547, Level 16, State 0, Line 1
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Sup_Item_Sup_Item_Cat". The conflict occurred in database "dev_bo", table "dbo.Sup_Item_Cat". The statement has been terminated.
Code:
insert into sup_item (supplier_id, sup_item_id, name, sup_item_cat_id,
status_code, last_modified_user_id, last_modified_timestamp, client_id)
values (10162425, 10, 'jaiso', '123123',
'a', '12', '2010-12-12', '1062425')
The last column client_id is causing the error. I tried to put the value which already exists in the dbo.Sup_Item_Cat into the column, corresponding to the sup_item.. but no joy :-(
In your table dbo.Sup_Item_Cat, it has a foreign key reference to another table. The way a FK works is it cannot have a value in that column that is not also in the primary key column of the referenced table.
If you have SQL Server Management Studio, open it up and sp_help 'dbo.Sup_Item_Cat'. See which column that FK is on, and which column of which table it references. You're inserting some bad data.
Let me know if you need anything explained better!
I had this issue myself, regarding the error message that is received trying to populate a foreign key field. I ended up on this page in hopes of finding the answer. The checked answer on this page is indeed the correct one, unfortunately I feel that the answer is a bit incomplete for people not as familiar with SQL. I am fairly apt at writing code but SQL queries are new to me as well as building database tables.
Despite the checked answer being correct:
Mike M wrote-

What is missing from this answer is simply;
You must build the table containing the Primary Key first.
Another way to say it is;
You must Insert Data into the parent table, containing the Primary
Key, before attempting to insert data into the child table containing
the Foreign Key.
In short, many of the tutorials seem to be glazing over this fact so that if you were to try on your own and didn't realize there was an order of operations, then you would get this error. Naturally after adding the primary key data, your foreign key data in the child table must conform to the primary key field in the parent table, otherwise, you will still get this error.
If anyone read down this far. I hope this helped make the checked answer more clear. I know there are some of you who may feel that this sort of thing is pretty straight-forward and that opening a book would have answered this question before it was posted, but the truth is that not everyone learns in the same way.
You are trying to insert a record with a value in the foreign key column that doesn't exist in the foreign table.
For example: If you have Books and Authors tables where Books has a foreign key constraint on the Authors table and you try to insert a book record for which there is no author record.
You'll need to post your statement for more clarification. But...
That error means that the table you are inserting data into has a foreign key relationship with another table. Before data can be inserted, the value in the foreign key field must exist in the other table first.
The problem is not with client_id from what I can see. It looks more like the problem is with the 4th column, sup_item_cat_id
I would run
sp_helpconstraint sup_item
and pay attention to the constraint_keys column returned for the foreign key FK_Sup_Item_Sup_Item_Cat to confirm which column is the actual problem, but I am pretty sure it is not the one you are trying to fix. Besides '123123' looks suspect as well.
Something I found was that all the fields have to match EXACTLY.
For example, sending 'cat dog' is not the same as sending 'catdog'.
What I did to troubleshoot this was to script out the FK code from the table I was inserting data into, take note of the "Foreign Key" that had the constraints (in my case there were 2) and make sure those 2 fields values matched EXACTLY as they were in the table that was throwing the FK Constraint error.
Once I fixed the 2 fields giving my problems, life was good!
If you need a better explanation, let me know.
I ran into this problem when my insert value fields contained tabs and spaces that were not obvious to the naked eye. I had created my value list in Excel, copied, and pasted it to SQL, and run queries to find non-matches on my FK fields.
The match queries did not detect there were tabs and spaces in my FK field, but the INSERT did recognize them and it continued to generate the error.
I tested again by copying the content of the FK field in one record and pasting it into the insert query. When that record also failed, I looked closer at the data and finally detected the tabs/spaces.
Once I cleaned removed tabs/spaces, my issue was resolved. Hope this helps someone!
Double check the fields in the relationship the foreign key is defined for. SQL Server Management Studio may not have had the fields you wanted selected when you defined the relationship. This has burned me in the past.
run sp_helpconstraint
pay ATTENTION to the constraint_keys column returned for the foreign key
I had the same problem when I used code-first migrations to build my database for an MVC 5 application. I eventually found the seed method in my configuration.cs file to be causing the issue. My seed method was creating a table entry for the table containing the foreign key before creating the entry with the matching primary key.
Parent table data missing causes the problem.
In your problem non availability of data in "dbo.Sup_Item_Cat" causes the problem
I also got the same error in my SQL Code, This solution works for me,
Check the data in Primary Table May be you are entering a column value which is not present in the primary key column.
The problem was reproducible and intermittent for me using mybatis.
I'm sure I had correct DB configuration (PK, FK, auto increment etc)
I'm sure I had correct order of insertions (parent records first), in debug I could see parent record inserted with respective PK and just after that next statement failed with inserting child record with correct FK inside.
The problem was fixed by for reseeding identity with
DBCC CHECKIDENT ('schema.customer', RESEED, 0);
DBCC CHECKIDENT ('schema.account', RESEED, 0);
Exactly the same code that failed before started to work.
I would like somebody to explain me what was causing the issue.
In my case, I was inserting the values into the child table in the wrong order:
For the table with 2 columns: column1 and column2, I got this error when I mistakenly entered:
INSERT INTO Table VALUES('column2_value', 'column1_value');
The error was resolved when I used the below format:-
INSERT INTO Table (column2, column1) VALUES('column2_value', 'column1_value');
If your FK column table should contain that FK value as a primary key Value then data will be inserted.
A business user requested that I change a dropdown list to a textbox for creating records. The dropdown list is what was created by default for relating to tables in my database. As requested I made the change and replaced the dropdown list with an #Html.EditorFor element. I now get this error message when I try to create records. Is there a possible solution that can fix this error? There aren't any syntax errors that stop me from compiling my code. This error occurs at runtime.
This means that your forward thinking database designer placed a constraint in your database to stop people entering invalid values. Your application allows the user to enter invalid values, but luckily your database is stopping it.
A foreign key is how you ensure that a table only gets it's 'lookup' values from a valid list.
If you remove the constraint you will risk putting garbage into your database that is a great effort to fix.
If you start putting invalid values in this table it means things like inner joins stop working and data starts going missing in reports.
Need a bit more information such as tables being inserted and the foreign keys on it. Likely the text entered doesn't match that of the drop down. You would likely have to remove the foreign key. However if the design was that a numeric value was being inserted and not just a text one, The users now have a text area... where's the numeric value (I'm assuming some design here which is why I asked for tables and keys)? I'd likely do the following:
Change the table structure so that the value being inserted is character based (if not already)
Remove key constraint
Update the existing records so the text of the lookup value is replacing the numeric values (assuming numeric design of foreign key.
Drop original lookup table.
Alter design so code uses distinct on the column in the remaining table for it's list of values.
The alternative is that you'd have to insert the new text value first into the lookup table, then get it's new key value then do the insert statement. I suppose this could be handled with triggers and a before update statement but the question; but unless there's a reason to keep them separate, the above numbered list seems simpler in the long run
Previously with the dropdown, you were allowing the user to chose from the predefined values, i.e. values that were present in your lookup table to which you have put a foreign key constraint. But now as user can enter any value(which might not be present in the foreign table) thus resulting in this error.
To remove this error you can drop the constraint
ALTER TABLE <TABLE_NAME> DROP CONSTRAINT <FOREIGN_KEY_NAME>
or check the value(against the foreign key table) entered by user before inserting it.
UPDATE
If you have removed the foreign key constraint, then you'll have to insert any new(you'll have to check if data is new or old) data in the lookup table, assign it an ID and then insert this new ID in the main table to create the link between the two. NOTE: You can maintain the foreign key constraint in this case.
Assume that I know that updating a primary key is bad.
There are other questions which imply that the inserted and updated table records match by position (the first of one matches the first of the other.) Is this a fact or coincidence?
Is there anything that could join the two tables together when the primary key changes on an update?
There is no match of inserted+deleted virtual table row positions.
And no, you can't match rows
Some options:
there is another unique unchanging (for that update) key to link rows
limit to single row actions.
use a stored procedure with the OUTPUT clause to capture before and after keys
INSTEAD OF trigger with OUTPUT clause (TBH not sure if you can do this)
disallow primary key updates (added after comment)
Each table is allowed to have one identity column. Identity columns are not updateable; they are assigned a value when the records are inserted (or when the column is added), and they can never change. If the primary key is updateable, it must not be an identity column. So, either the table has another column which is an identity column, or you can add one to it. There is no rule that says the identity column has to be the primary key. Then in the trigger, rows in inserted and updated that have the same identity value are the same row, and you can support updating the primary key on multiple rows at a time.
Yes -- create an "old_primary_key" field in the table you're updating, and populate it first.
Nothing you can do to match-up the inserted and deleted psuedo table record keys -- even if you store their data in a log table somewhere.
I guess alternatively, you could create a separate log table that tracked changes to primary keys (old and new). This might be more useful than adding a field to the table you're updating as I suggested right at first, as it would allow you to track more than one change for a given record. Just depends on your situation, I guess.
But that said -- before you do anything, please go find a chalk board and write this 100 times:
I know that updating a primary key is bad.
I know that updating a primary key is bad.
I know that updating a primary key is bad.
I know that updating a primary key is bad.
I know that updating a primary key is bad.

:-) (just kidding)
I have Table-A with a column called serial_number, and Table-B has the same column.
Update a single table is not possible to their linkage, upon attempt though, this is the error:
The UPDATE statement conflicted with the FOREIGN KEY constraint
"L_231". The conflict occurred in
database "Main", table "dbo.Products".
The statement has been terminated.
I know how I can delete the field in both in case I need to, I just don't know how to update it simultaneously.
Thanks.
this is a BAD design. if this isn't a "one time thing" to fix an issue, but part of your applicaion, you need a redesign.
You shouldn't update keys, use a surrogate key (like an identity) instead and then store the serial_number as a plain data column (which can be easily changed).
You should be able to set the constraint as ON UPDATE CASCADE.

Good question but ????
one Method is Update trigger
you update in same time on different table
