I am using rubyonrails 3.2 with oracle.
My table have an optimistic column so I added
self.locking_column = 'my_col'
in the model.
When I try to update a record, I can see the WHERE my_col = 42 but ror also try to set the new value (SET my_col = 43), which oracle does not accept (it update the value itself).
How can I make ror to not set the new value?
An error in the ORA-20000..20999 range is a user application error - in this case, there will be a trigger with some code that raises this error.

I am executing following UPDATE sql query against oracle database server -
UPDATE TEST.SS_USER_CREDENTIALS SET CREDENTIAL = 'UUHs4w4Nk45gHrSIHA==';
After executing this query in Oracle SQL developer, I can see spinner of execution status of query keeps spinning forever and hence no output is returned. However following SELECT query on same table returns result immediately -
SELECT * FROM TEST.SS_USER_CREDENTIALS;
Could you please help to understand why UPDATE query is not executed?
If you don't have autocommit enabled, you may need to run
COMMIT;
Otherwise oracle updates aren't actually applied to your data set
try with where clause
UPDATE TEST.SS_USER_CREDENTIALS SET CREDENTIAL = 'UUHs4w4Nk45gHrSIHA==' where id='someid';
as I see your command if the table has trillion of rows it will take time (as I guess this should not be foreign key)
UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;
If you are looking for a temp solution you can also change the ON UPDATE action to CASCADE and modify your ids if you got a foreign key problem
it can be you have another open uncommitted transaction for the same set of records, so they are locked for that transaction.
if you locked them, running the same UPDATE in another transaction.
Just Commit/rollback your transactions
This works for me:
Close the database connection and refresh it
Refresh the table
Restart the SQL Server in services
I know this is not a complete answer to this, hope it helped!
I tried to update the field "contract_id" in the table "contract_scan_image".
However, the update was failed and an error "746: Field contract_id and type of contract_scan_image cannot be updated!" was shown.
My SQL command is:
update contract_scan_image
set contract_id = '14864730'
where contract_id = '1486473'
and type = 'RM'
and account = '00193400944'
Does anyone know what happened and how to fix it?
Error message -746 is for user-defined errors. It typically is used in stored procedures in a RAISE EXCEPTION statement:
RAISE EXCEPTION -746, 0, "Field contract_id and type of contract_scan_image cannot be updated!"
The actual message text for error -746 in the message files is:
%s
That is, it prints the string it is given as a string.
So, you are going to need to track down the triggers and stored procedures invoked by those triggers on the contract_scan_image table, and deduce from where the error is generated what you are doing wrong. Superficially, though, it appears that you are not allowed to alter the contract ID, yet that is what you are trying to do.
First things first, I would take a look at a list of Reserved words in SQL - https://drupal.org/node/141051
I would get in the habit of surrounding fields with `` See below:
update contract_scan_image
set `contract_id` = '14864730'
where `contract_id` = '1486473'
and `type` = 'RM'
and `account` = '00193400944'
** Note - type is a reserved word
The error is caused by something being triggered. Then no table can be modified by UPDATE command.
Finally I deleted the record I want to update. Then added back the modified record.
I copy the error description here from the net for reference.
BTW, I asked my supervisor and he said he did trigger something to cause this. (He didn't tell me how to un-trigger it...)

THE SQL STATEMENT IN FUNCTION, TRIGGER, OR IN STORED PROCEDURE name VIOLATES THE NESTING SQL RESTRICTION
Explanation
If a table is being modified (by INSERT, DELETE, UPDATE, or MERGE), the table can not be accessed by the lower level nesting SQL statement.
If any table is being accessed by a SELECT statement, no table can be modified (by INSERT, DELETE, UPDATE, or MERGE) in any lower level nesting SQL statement.
System action
The SELECT, INSERT, DELETE, UPDATE or MERGE SQL statement failed.
Programmer response
Remove the failing statement from the named function, trigger or the stored procedure.

I'm having a strange problem with an SQLite Database, specifically with data validation on an UPDATE query. So let me begin, if i use the following query, i get a 'datatype mismatch' error when i try to run it. This is correct and expected because the field type is marked as an integer.
INSERT OR REPLACE INTO Table ('Column') VALUES ('shouldFail')
However, one would also expect that the following UPDATE query should return the same 'datatype mismatch' error, but it doesn't. I can run the following query perfectly fine, which allows me to end up with a 'String' data type in a column which is marked as INTEGER only...
UPDATE Table SET 'Column'='shouldFail' WHERE SecondColumn = 'Some value'
So can anyone tell me why the SQL datatype validation is working on the first query, but not on the second?
Many Thanks
Sam
With my MySQL knowledge I'd say that REPLACE is not an UPDATE, it's an DELETE, THEN INSERT. Further I bet your database is set to raise only a warning when a row is updated with wrong datatype and the value is set to default value (0 for integer). Inserts fail, updates raise warnings. Unfortunately I'm not that familiar with sqlite, but I heard somewhere they are not that different?
P.S.: Try SHOW WARNINGS; and see if there's something...
I would like the following SQL query to be executed in a migration file after adding a column (updating the new field with existing column value from the same row)
UPDATE users SET last_login=updated_at;
The SQL statements work properly when executed on the database, but in rails I tried multiple syntax using the ActiveRecord update_all method but without success
User.update_all("last_login=updated_at")
I get the following error
ActiveRecord::StatementInvalid: PGError: ERROR: current transaction is aborted, commands ignored until end of transaction block
: UPDATE "users" SET last_login=updated_at
Obviously something is missing in my syntax, but can't figure out what.
Can anyone point me to the right syntax?
Regards/J.
Syntax is indeed correct, the issue was relying in the fact that I had to rollback the previous transaction.
User.update_all("last_login=updated_at")
This statement works properly.
I am trying to update a row on an SQL SERVER 2005. When I run the SQL, I receive a message indicating that the Execution was successful and 1 row was affected. However, when I do a select against this row I supposedly updated, the value remains unchanged. What's going on with this SQL server when a successful query does absolutely nothing.
The query is:
UPDATE [database1].[dbo].[table1]
SET [order] = 215
WHERE [email] = 'email#email.com'
check for a trigger on [database1].[dbo].[table1], possibly it is doing something you are not aware of.
EDIT
without seeing the trigger code, you probably just need to add support for [order] into the trigger, since it is a new column (based on your comment).
Thanks KM I checked the triggers and you were right. There was a trigger that I had to disable to get the sql to work.
