I have a table that needs to be reorganised using the reorg command in DB#, However due to large size of the table, I am unable to do so. So I plan to delete entire data from the table and then do any reorg if required..
Is there any possible way for doing so?
I already used
DELETE FROM TABLE-NAME
and
TRUNCATE TABLE SCHAME-NAME.TABLE-NAME IMMEDIATE
But both the above queries aren't working and are giving the following error which is the one for reorg.
Error: DB2 SQL Error: SQLCODE=-668, SQLSTATE=57016, SQLERRMC=7;DB2ADMIN.CERTIFICATE_TAB, DRIVER=3.50.152
SQLState: 57016
ErrorCode: -668

We have a stored procedure in SQL Server which inserts data from a staging table into a fact table. This is first joined onto various dimension tables to get their id columns.
Intermittently, it will throw the following error:
('42000', '[42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Cannot bulk load. The bulk data stream was incorrectly specified as sorted or the data violates a uniqueness constraint imposed by the target table. Sort order incorrect for the following two rows: primary key of first row: (305603, 0xedd9f90001001a00), primary key of second row: (245634, 0x0832680003003200). (4819) (SQLExecDirectW)')
(The two rows mentioned in the error message usually change each time the error occurs)
The fact table doesn't have any primary key or clustered index, although it does have a few non-clustered indexes, so the error message is really confusing me.
The dimension tables DO have primary keys, but the fact table has no foreign keys related to them.
I have searched for hours on the internet but don't seem to have found a solution.
Does anybody know why I would receive such an error in this case? any help would be appreciated. We are using Azure SQL database.
I am aware that the database is badly designed however it was created before my time.
I have been getting the -668 error trying to expand a column from 8 octets to 20 octets. I got the -668 error which when I looked it up at ibm.com I got
"-668 THE COLUMN CANNOT BE ADDED TO THE TABLE BECAUSE THE TABLE HAS AN EDIT PROCEDURE DEFINED WITH ROW ATTRIBUTE SENSITIVITY"
So reading about an edit procedure, I see:
An edit procedure receives the entire row of a base table in internal Db2 format. It can transform the row when it is stored by an INSERT or UPDATE SQL statement or by the LOAD utility. An edit procedure can be defined as WITH ROW ATTRIBUTES or WITHOUT ROW ATTRIBUTES in a CREATE TABLE statement.
I did the reorg statement mentioned at
Failing update table in db2 with SQLCODE: -668, SQLSTATE: 57016, SQLERRMC: 7;
and then I could alter the table as I wished. However, the REORG seems to be more for defragging or somehow optimizing the table, but it does not say anything about removing an edit procedure. Could someone explain how there's an edit procedure, and further it has row sensitivity, yet there's no triggers, procedures in the schema that I can see. When I generated the DDL for the table, I didn't see anything suggesting an edit procedure.
Thanks for reading this post. I am running into a strange issue in Oracle 10g. I am trying to figure out how to truncate a table without errors being generated.
What I need to do:
truncate a table that my user owns
truncate table EXAMPLE_USER.EXAMPLE_TABLE;
What is happening: rows within the table are successfully removed, but the following error is generated:
Error starting at line 1 in command:
truncate table EXAMPLE_USER.EXAMPLE_TABLE
Error report:
SQL Error: ORA-00604: error occurred at recursive SQL level 1
ORA-00942: table or view does not exist
ORA-06512: at line 50
00604. 00000 - "error occurred at recursive SQL level %s"
*Cause: An error occurred while processing a recursive SQL statement
(a statement applying to internal dictionary tables).
*Action: If the situation described in the next error on the stack
can be corrected, do so; otherwise contact Oracle Support.
What I have already done:
Ensure that EXAMPLE_USER has the "drop any table" privilege
Make sure that the rows are removed after truncate statement is ran
Additional Info:
I cannot simply drop and re-create the table because the truncation happens as part of a large database upgrade/update script which is out of my control.
The error is leading me to believe that the truncate statement within Oracle uses some sort of sys package or procedure that my user does not have privilege to access or use, based on the "at line 50" portion of the message. The actual truncate statement itself is a single line script. Does anyone have experience with this issue in Oracle?

When entering the following command:
\copy mmcompany from '<path>/mmcompany.txt' delimiter ',' csv;
I get the following error:
ERROR: duplicate key value violates unique constraint "mmcompany_phonenumber_key"
I understand why it's happening, but how do I execute the command in a way that valid entries will be inserted and ones that create an error will be discarded?
The reason PostgreSQL doesn't do this is related to how it implements constraints and validation. When a constraint fails it causes a transaction abort. The transaction is in an unclean state and cannot be resumed.
It is possible to create a new subtransaction for each row but this is very slow and defeats the purpose of using COPY in the first place, so it isn't supported by PostgreSQL in COPY at this time. You can do it yourself in PL/PgSQL with a BEGIN ... EXCEPTION block inside a LOOP over a select from the data copied into a temporary table. This works fairly well but can be slow.
It's better, if possible, to use SQL to check the constraints before doing any insert that violates them. That way you can just:
CREATE TEMPORARY TABLE stagingtable(...);
\copy stagingtable FROM 'somefile.csv'
INSERT INTO realtable
SELECT * FROM stagingtable
WHERE check_constraints_here;
Do keep concurrency issues in mind though. If you're trying to do a merge/upsert via COPY you must LOCK TABLE realtable; at the start of your transaction or you will still have the potential for errors. It looks like that's what you're trying to do - a copy if not exists. If so, skipping errors is absolutely the wrong approach. See:
How to UPSERT (MERGE, INSERT ... ON DUPLICATE UPDATE) in PostgreSQL?
Insert, on duplicate update in PostgreSQL?
Postgresql - Clean way to insert records if they don't exist, update if they do
Can COPY be used with a function?
Postgresql csv importation that skips rows
... this is a much-discussed issue.
One way to handle the constraint violations is to define triggers on the target table to handle the errors. This is not ideal as there can still be race conditions (if concurrently loading), and triggers have pretty high overhead.
Another method: COPY into a staging table and load the data into the target table using SQL with some handling to skip existing entries.
Additionally, another useful method is to use pgloader
I want to delete all rows from table in sql server 2000 but whenever I want to delete manually or with query it shows error. In help tab it shows ODBC error: <0s>.
My table contains some '0' values but its datatype is String. Is that's the reason for this
error.
code is:
stat2=conn.createStatement();
stat2.executeUpdate("Delete * from pat.dbo.PHPL");
"Key column information is insufficient or incorrect. Too many rows were affected by update" that's warning and when click help it shows: ODBC error: <0s>. An ODBC error has been generated. You might have deleted a record that has a foreign key value related to it, or you might have violated a check constraint. For details, refer to your ODBC documentation.
Use
Truncate Table PHPL
I think you have duplicate identities, check you are not allowing duplicates on this column.
