• compare two table with cluster inside

  Hello

  I want to compare two tables containing a cluster with several groups in it. When you use the equal the result is the same pattern as the cluster of entry. But I just need a true or false. It doesn't bother me that it changed on position 1 or any other position.

  Is there an elegant way to do it?

  Thanks for any help.

  Right-click equality and change to compare aggregations. That, or add a table and later.

• Compare two tables, APEX

  Hello
  
  I am trying to compare two tables, but I want to display values that are the differnet from one to the other,
  both tables have the same columns and have the same PK.
  
  Thank you.

  Hello

  You probably need a report based on a query like this:

  SELECT
     d1.deptno,
     d1.dname,
     d2.dname,
     d1.loc,
     d2.loc
  FROM
     dept1 d1
     INNER JOIN dept2 d2
     ON d1.deptno = d2.deptno
     AND (      d1.dname <> d2.dname
              OR d1.loc <> d2.loc
            )
  

  You can also consider using FULL JOIN where you have different values of primary key in both tables and you want to include in the report.

• BUG? Statement of BRIDGE to compare two tables

  Hello
  
  I tried to compare two tables different dbs and remembered a post on applications to Connectin Cross
  http://barrymcgillin.blogspot.com/2010/11/cross-connection-queries.html

  BRIDGE temparb AS "EB05 01"
  (SELECT * FROM arb)
  (SELECT * FROM temparb 
  MINUS 
  SELECT * FROM arb
  )
  UNION ALL
  (SELECT * FROM arb
  MINUS
  SELECT * FROM temparb 
  );

  I expect to get the differences between the ARB table in my current schema and the table alias temparb arb in the other db. Yet it seems that in this case only the table in my current schema is read.
  
  I materialize at the table BRIDGE with

  BRIDGE temparb AS "EB05 01"
  (SELECT * FROM arb)

  and select the value that I know to be only in the remote schema

  SELECT id FROM temparb WHERE id = 2562;
  SELECT id FROM arb WHERE id = 2562;

  Both times I get no results. I even tried to use aliases on the table, same result. Tested in EA3 3.0 and 3.1.
  
  Has anyone tried this before?

  Hi Marcus,

  Have you tried without the quotes around the name of connection?

  I have a named connection
  system_local
  which I run the following command

  drop table testbridge_remote;
  drop table testdbrige;
  create table testbridge (col1 int);
  insert into testbridge values (1);
  insert into testbridge values (2);
  insert into testbridge values (3);
  commit;

  I have a named connection
  Name of the connection with space
  I performed the following in the

  drop table testdbrige;
  create table testbridge (col1 int);
  insert into testbridge values (4);
  insert into testbridge values (5);
  insert into testbridge values (3);
  commit;

  Then I can execute the following statement in the connection of system_local/worksheet

  BRIDGE testbridge_remote as the name of connection with Space(select * from testbridge)
  + (SELECT * FROM testbridge_remote +)
  LESS
  SELECT * from testbridge
  +)+
  UNION ALL
  + (SELECT * FROM testbridge +)
  LESS
  SELECT * from testbridge_remote
  +);+

  It works well.
  Returns the rows in the remote table not in the local table and lines in the local table, not the remote table.

• Compare two table

  Hello

  can you please help me.

  How can I compare two table. following my code...

  var my_array:Array = Array (5,10,15,20,25,30)
  var new_array:Array = Array (7,8,9,10,11,12,13)
  for (var i: Number = 0; i < my_array.length; i ++) {}
  {if(my_array[i]==new_array[i])}
  trace (my_array [i])
  }
  }

  Thanks in advance,

  JaxNa

  Then, you're almost on correct... See the same code that I modified a little,

  var my_array:Array = Array (5, 10, 15, 20, 25, 30);
  var new_array:Array = Array (7, 10, 9, 10, 10, 30, 13);

  for (var i: Number = 0; i
  If (my_array [i] is {new_array [i]})
  trace ("' my Array'" + i + "("+my_array[i]+")"new_array' "+ i +"("+new_array[i]+") = Matching");
  } else {}
  trace ("' my Array'" + i + "("+my_array[i]+") 'new_array'" + i + "("+new_array[i]+") = is only not to");
  }
  }

  If this is not so, explain exactly what you want

• Compare two Tables question

  Hello
  
  I need to compare two tables (T1, T2) and update existing records only in T2, but not in T1. So basically, the lines updated in T2:
  
  Select * from T2 where T2.id not in (select id from T1).
  
  What would be a good way to achieve this in ODI?
  
  I created an ODI interface with a join T2.id not in T1.ID, but it did not work "coz:" ORA-01427: einreihig subquery returns several lines "."
  
  Appreciate any input/access map.
  
  Thank you.

  Hi Michele...

  At first glance, there are at least 2 ways to do it:

  (1) put the steps in "(select id from T1)" (you can use an ODI API to get the schema dynamically) as an object filter to T2 (interface), use the incremental update IKM SQL and put "Insert" option on 'No'. " This will do a few updates.

  OR

  (2) in an interface set the T1 and T2 and left join (based on T2) load a temp table where all fields accept the value zero. Next to the columns to update (of course the T2), create an ID column (I named him as T1_Temp_ID) and map the Id of the T1 to it.
  Now just create new interface where the temperature is source and put a filter like "T1_Temp_ID is not null.

  The first option is less complex and can bring better performance.
  The second option gives a better follow-up of the use of the table and the columns, but can be less performatique.

  This help you?

• compare two tables and update the differences

  Hi all
  Sorry for the newbie question, but I am a beginner in the present.
  
  I have two tables, both have same structure-
  
  CODE - code NUMBER (6,0) store is the primary key does not change and is unique
  ADDRESS1
  ADDRESS2
  ADDRESS3 - all VARCHAR2 (100)
  
  One of the tables is named MASTER, the other being updated. MASTER contains hundreds of lines, while the table of UPDATES may have anywhere from zero to 10 or more.
  I want to compare the table of UPDATES against the MASTER of the table and if there is a difference, ask the differences in the table in UPDATES to the MASTER of table - so if the address of an Exchange store, then the change is reflected in the MASTER table by crushing with the data contained in the UPDATES table.
  
  I thought that maybe using sliders and compare each field but there must be a more efficient way.
  
  I hope that I have explained quite clearly... any help would be greatly appreciated.
  
  Thank you

  Thank you

  Based on your last post that only good data must match exactly and your definition of junk:

  WHERE (decode (substr (A.col5, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ', "junk," A.col5 ") = decode (substr (B.col5, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ',"junk", B.col5"))

  AND (decode (substr (A.col6, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ', "junk," A.col6 ") = decode (substr (B.col6, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ',"junk", B.col6"))

  And so on for the six columns.  This assumes that this junk * still * starts with a ~.  In addition, it assumes that the unnecessary and null words are not in the form of good data.

• How to compare data from the two table column by column and connect the result compared to the separate table

  Hello experts...

  I'm new to this forum and Oracle coding complex.

  I have a task in which I want to compare two tables with the same structure, same columns. My Oracle database is 11g Release 2. I want this column-by-column comparison and save the result in a separate table. (say result_table)

  The structure of the table would be as follows:

  SQL > desc emp;

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  EMPNO NOT NULL NUMBER 4

  ENAME VARCHAR2 (10)

  JOB                                                VARCHAR2(9)

  MGR                                                NUMBER(4)

  HIREDATE DATE

  SAL                                                NUMBER(7,2)

  COMM                                               NUMBER(7,2)

  DEPTNO NUMBER (2)

  SQL > emp_comp desc;

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  EMPNO NOT NULL NUMBER 4

  ENAME VARCHAR2 (10)

  JOB                                                VARCHAR2(9)

  MGR                                                NUMBER(4)

  HIREDATE DATE

  SAL                                                NUMBER(7,2)

  COMM                                               NUMBER(7,2)

  DEPTNO NUMBER (2)

  Both of the tables EMPNO is the primary key.

  I want to compare these two tables based on the EMPNO (EMPNO even is both tables).

  The result log table would be as follows:

  SQL > create table result_table

  2 (check_sr_no, number (5),)

  table_name 3 varchar2 (30),

  ROW_ID 4 varchar2 (20).

  column_name 5 varchar2 (20).

  6 column_data varchar2 (1000).

  compared_by 7 varchar2 (10));

  Table created.

  SQL > alter table result_table

  2 Add the constraint result_table_pk

  3 primary key (check_sr_no);

  Modified table.

  The name of the table and the name of the column will not be hardcoded (based parameter by user)

  I tried to use the dbms_comparison package, but do not find comparison of column to column.

  I also used by using the query operator LESS. It's showing the difference in rank.

  I also went to https://asktom.oracle.com/pls/apex/f?p=100:11:0:P11_QUESTION_ID:2151582681236

  Your help will be very appreciated.

• Stored procedure to compare two data tables

  Hello
  
  I want to have a stored procedure that will compare two tables data (only one column) and remove the line that is not present in the second table.
  
  For example.,.
  I have 2 tables called Table1 and Table2, that have the same column called ID (PK).
  Data in Table1 are 1,2,3 and data into Table2 are 1.3. When the stored procedure is running, it must compare the ID column in Table1 to ID column in Table2 and since '2' is not there in Table2, I want to remove this line from Table1.
  
  Thanks in advance.

  delete from table1
  where does not exist (select 1 from table2 where table2.id = table1.my_field)
