  • Oracle error messages may seem like annoying roadblocks, but some of them are actually designed to make the customer base more efficient in some way. While this may seem counterproductive, if the program simply allowed dataIf a user could make Oracle mistakes, it wouldn’t evolve into the dynamic, optimized database product it’s known for. The error message ORA-00001 points to this pattern of thinking.

    How do you know when a unique constraint is violated?

    Drop unique index/constraint on table A.Run an update/insert/merge query on table A.Run select col_b, col_c, col_d, count(*) on table group A because col_b, col_c, col_d have count(*) > 1.The results of the predicament reveal your perpetrator(s).Correct data/request.Recreate this unique constraint/index on table A.

    ORA-00001 information is triggered when a clear discipline is violated. Essentially, your user raises an error when they try to run an INSERT or UPDATE declaration that generated a duplicate reward on a restricted field. Errors can often be found when a real program tries to insert a borrowed row into a table.

    How do I fix Ora 00001?

    Modify the better SQL so that the unique constraint is not violated.Change the restriction to allow duplicate values.Remove the constraint from the column.Turn off completely differente limitation.

    Before discussing the progress of the problem, it is desirable to get more information about the error. If you’re not at all sure what the constraint that appears to have been violated to cause ORA-00001 is, you can run an SQL statement to get important information about it. You can enter my following command:

    SELECT DISTINCT table_name
    FROM all_index
    WHERE index_name = ;
    'constraint_name'

    Restriction detection can be found by looking for errors in the message itself. The limit must be specified in parentheses after the ora-00001 notice. Then this pThe process will definitely return the name of its table containing the broken problem.

    Now that we know the constraint and the table in question, we can move on to troubleshooting the problems themselves. There are several main options. You can change the SQL to not create duplicate values ​​and not throw errors. If you don’t want to, you can just exclude the most important table altogether. This is only recommended if the restriction is really not necessary for your workplace.

    How do you fix a violation of unique key constraint?

    Find the table where this violation occurred.Find out if there are any cleanups associated with the table as a whole.If there is no loss or if the purge is configured correctly, look at the keys in the table to understand which service sector is most likely the problem.

    Another option could be some kind of change restriction, so it could also allow for duplicate values ​​in your common. Several tricks can be achieved depending on your version of this oracle. The first and universal method, of course, will be to manually set the limit. However, if you are using Oracle 11g or Flourishing, you can use the Ignore_row_on_dupkey_index flag. This advantage allows you to insert duplicate SQL and actually ignore them to avoid running the ORA-00001 project.

    Tips like this can help you get around the ORA-00001 error in many cases. The trigger method can also be a proactive approach to minimize the rate of ORA-00001 errors. These autoincrement columns may want to override the initial value of the identifier by inserting the initial value into the subroutine in its place. On a very large scale, being aware of the various constraints you typically work with helps you not only avoid mistakes, but more importantly, be able to react quickly when they occur. If you’re still unsure about some of these specific limitations of your tables, or want to know more about some of the latest versions of Oracle that contain favorable references to Ignore_row_on_dupkey_index, it might be worth contacting a Las Vegas bankruptcy attorney using your Oracle license. . -Advice for other ideas.
