How to delete records from a table that has a composite unique key duplicate

Hello
I get the customer data from various sources in the staging of the table where I insert in the database table where the combination of two columns is considered as a unique key. But there is a possibility of duplicates. How to find duplicates in a SQL or pl/sql

Thank you
Manoi.

Kassa,

You can see the duplicates by using the following query...

sql> select * from temp_rajesh;

      COL1       COL2 MESSAGE
---------- ---------- ------------------
       100        200 message
       100        200 message2
       300        400 message3
       400        500 message 4

sql> select col1, col2, count(*)
  2     from temp_rajesh
  3       group by col1, col2
  4         having count(*) > 1;

      COL1       COL2   COUNT(*)
---------- ---------- ----------
       100        200          2

-If in the case of duplicate records, you should see only the duplicates (according to some timestamp etc., you can use the functinon row_number analytic..)

  1  select col1, col2 from (
  2  select col1, col2,
  3         row_number() over (partition by col1, col2
  4                            order by message) rn
  5    from temp_rajesh)
  6*   where rn > 1
sql> /

      COL1       COL2
---------- ----------
       100        200

In the above example, I use message to order, you can replace it with activity_timestamp or the insertd_date according to your logic... when there are two records... one that you choose to duplicate.

Thank you
Rajesh.

    Nope.
    You can insert into multiple tables by using a single query, INSERT ALL job, but you cannot delete more than one table using a single query.

  • How replicates all records from one table to another table without using expdp, impdp

    Hi I have two database in a database, that I have a table called t1 and another base data, I have the second table .so, my first table have records, that I need to transfer all records second T2 without use of expdp and impdp in every 5 min... what I do

    ??

    The best solution for this scenario is to use Oracle Golden Gate

    However, it requires a license, and you must pay for it.

    If this is not possible, you can create a job scheduler that uses a link DB in order to reproduce the recordings of the target database, but it will take the entire table to the target database and then INSERT AS SELECT truncate the data of the entire table every time that the job is running (because you can't follow only the records that have been changed or modified).

    In addition, read here on the replication of data using materialized views.

  • How to delete columns from a table

    Hello

    I have a 2D chart composed of 12 columns. I want to just use the first three columns within LabView. What is the best way to extract the data from these three columns?

    Greetings

    Kristoffer

    You can watch from two different angles:

    • You can remove the extra columns
    • You can keep only the fist three columns

    Would be easier to use "subset of the table" and select the first three columns. See photo.

    (This assumes you want the three columns as a 2D array. If you want in three tables 1 d, you would use 'index array' resized to three exits.)

    You should not select Trial1 - you already have data. Simply insert this value.

    Create or replace trigger trg_move_to_trial2
After insert on Trial1
for each row

begin

  • Delete records from sys.aud$ stored procedure

    We have a stored procedure that attempts to move the records from the table of sys.aud$ to a history table (in order to keep sys.aud$ to a more reasonable size, I guess - full disclosure, I have not written this proc). Base flow is:
    Select count (*) in the number of lines of sys.aud$
    If {(rowcount > 1000)
    copy all rows in sys.aud$ in the history table
    remove from sys.aud$
    }

    I says this proc used to work perfectly in a troubled past (I'm new on the client) but now has not worked for a while. When we try to compile the proc, we get the error
    "table or view does not exist", and the line is the "deletion of sys.aud$. The line "select count (*) from sys.aud$ ' seems to cause no problems, but the proc does not compile as is. If I comment out the line "remove from sys.aud$", however, the proc compiles very well.

    Confusingly, if I log in as the same account that owns this proc, I can run both the count (*) select from sys.aud$ AND remove clauses sys.aud$ with no complaint at all (by modifying slightly to work with 1 single record at a time, of course), but I can't seem the same to compile in a stored proc.

    I guess that it is related permissions? Can someone point me to the permissions of the owner needs to be able to remove from sys.aud$ in a stored procedure? Or is there something else that needs to be done here? Pointers much appreciated.

    Thank you.

If you don't want this to be the case, do not share some files on the network. In other words, if I don't want then it in my music, I do not share my music directory.

  • The use of sequence and generate the number in a table that has data

    Hello

    There is a custom table that has a column Rowid (NULL).
    This table already has 10 k with rowid as null lines, now the user asks me to enter a unique number for the Rowid.
    I created a sequence, but don't know how to use this sequence and generate numbers for the Rowid.

    Could you suggest.

    Thank you.

    "rowid" is an oracle reserved word and should be avoided. Perhaps "Rowid" between quotes or something.

    Here's how to "fill" a column by a sequence:

    SQL> create table t (id number, value varchar2(100));

Table created.

SQL> insert into t (value) select object_name from all_objects where rownum <= 10000;

10000 rows created.

SQL> create sequence idgen_sequence;

Sequence created.

SQL> update t set id = idgen_sequence.nextval;

10000 rows updated.

    Given that the sequence was used all the 'id's will be unique.
