Delete rows in a table when the columns from two tables match

• The column that does not match when comparing two records

  Hi all

  We try to compare two tables and find the differences. So if two records (1 of each table) have same PK but not always matching because of some columns, then we would display this columnname. For example:

  Table 1

  PK	Parent	Child	Property1	Property2
  1	A	A1	P1	PR1
  2	B	B1	P2	oraPR2
  3	C	C1	P3	SRP

  Table 2

  PK	Parent	Child	Property1	Property2
  1	A	A1	P1	PR1
  2	B	B1	P2	PR2
  3	C	C1	P3	PR4

  In the above example when I compare 2 tables all matches except Property2 online n ° 3. Thus, we would like to get an output like:

  PK	Column_Mismatch
  3	Property2 (this must be the name of the column that does not match)

  Appreciate the help.

  Thank you

  Why you don't want no matter what exit for pk = 2?  Property2 does not correspond either to pk.

  What happens if the 2 columns (or more) do not match?  The following query would produce a list delimited, such as ' parents; PROPERTY2 '.

  WITH got_mismatch AS

  (

  SELECT pk

  , CASE WHEN t1.parent <> t2.parent THEN '; PARENT' END

  || CASE WHEN t1.child <> t2.child THEN '; CHILD ' END

  || CASE WHEN t1.properry1 <> t2.property1 THEN '; PROPERTY1 ' END

  || CASE WHEN t1.properry2 <> t2.property2 THEN '; PROPERTY2 ' END

  AS the offset

  FROM table_1 t1

  JOIN table_2 t2 ON t2.pk = t1.pk

  )

  SELECT pk

  , SUBSTR (incompatibility, 3) AS column_mismatch

  OF got_mismatch

  WHERE mismatch IS NOT NULL

  ;

  If you would care to post CREATE TABLE and INSERT statements for your sample data, and then I could test this.

  The query above does not count NULL values as inadequate.  If you want that, the same basic approach will work, but you can use DECODE instead of <> to compare columns.

  What happens if a pk exist in a table, but not the other?  You want an outer join, where I used an inner join above.

  Hello

  I read on how to do to remove a compressed table column - first set unused and then drop unused columns. However, in the example below on the basis of data, I ran it, it does not work. Please, can you tell me WHEN this approach does not work. What is dependent on - settings or something else. Why can't I drop unused columns?

  And the example and errors:

  create table tcompressed compress in select * from all_users;

  > TCOMPRESSED table created.

  ALTER table tcompressed add x number;

  > table TCOMPRESSED altered.

  ALTER table tcompressed drop the x column;

  >

  Error report:

  SQL error: ORA-39726: unsupported operation column add/drag on compressed tables

  39726 00000 - "operation column add/drop not supported on compressed tables. ''

  * Cause: Not support add/column operation move compressed tables

  elapse.

  * Action: When adding a column, do not specify a default value.

  DELETE column is only supported in a column SET UNUSED

  (remove the column metadata).

  ALTER table tcompressed unused column of the set x;

  > table TCOMPRESSED altered.

  ALTER table tcompressed drop unused columns;

  >

  Error report:

  SQL error: ORA-39726: unsupported operation column add/drag on compressed tables

  39726 00000 - "operation column add/drop not supported on compressed tables. ''

  * Cause: Not support add/column operation move compressed tables

  elapse.

  * Action: When adding a column, do not specify a default value.

  DELETE column is only supported in a column SET UNUSED

  (remove the column metadata).

  As you can see even after changing the table defining the column as unused X I still can't drop by DROP UNUSED COLUMNS.

  Thank you.

  If you enable compression for all operations on a table, you can delete the columns in the table. If you enable compression for the only direct-path inserts, you can't remove columns.

• update other items with the same value when when the column contains Y

   
  CREATE TABLE TEST 
     (     "QUATINTY" NUMBER(17,2), 
       "AMOUNT" NUMBER(17,2), 
       "ERRORRED" VARCHAR2(16 BYTE), 
       "PO" VARCHAR2(12 BYTE), 
       "LINE" VARCHAR2(10 BYTE), 
       "SEQ" VARCHAR2(14 BYTE), 
       "INVOICE" VARCHAR2(16 BYTE)
     ) 
  
  Insert into TEST (PO,QUATINTY,AMOUNT,ERRORRED,LINE,SEQ,INVOICE) values ('123',5,50,'Y','1','1','inv1');
  Insert into TEST (PO,QUATINTY,AMOUNT,ERRORRED,LINE,SEQ,INVOICE) values ('123',5,50,null,'1','2','inv1');
  Insert into TEST (PO,QUATINTY,AMOUNT,ERRORRED,LINE,SEQ,INVOICE) values ('125',5,50,null,'1','1','inv2');
  Insert into TEST (PO,QUATINTY,AMOUNT,ERRORRED,LINE,SEQ,INVOICE) values ('125',4,50,null,'1','2','inv2');

  If you notice the table above which im trying to Edifier is updated the errorred column with 'Y' if the po and invoice are the same and have a 'Y' on the wrong column.
  in other words, I should finish with "Y" in the column for INV1 errorred.
  Can someone point me in the right direction, I can't for the life of me figuered it out.

  Hello

  Here's one way:

  UPDATE     test
  SET     errorred     = 'Y'
  WHERE     NVL (errorred, 'N') != 'Y'
  AND     (po, invoice)          IN (
                            SELECT  po, invoice
                       FROM      test
                       WHERE      errorred  = 'Y'
                             )
  ;
  

  This requires that the po and invoice are not NULL. If a column can be NULL, then the solution might be a little messier, according to the results you want, but only a little. Post some sample data (with null values) which shows what types of situations, you need manage, and the results of the SAMPLES.

• the column 'from' on my mail has changed all the names being a sender

  I get messages from PayPal payment everytime someone pays me. The problem is on one of my email accounts that include all messages from PayPal for payments received from them. Everyone who sent me a payment last week all have the column with name changed to one name instead of that the message was in fact. The column now has only one customer name in it.

  For example:

  The original message in the column used to say "John doe via Pay Pal"... Now all the messages in the column now say 'jane doe via Pay Pal' when they said originally from john doe. All payments that have been received before and after this specific one payment now all read 'jane doe via Pay Pal' and NOT what they initially said in the column.

  I checked with my webmail provided and verified that the e-mail server and e-mail messages are properly formatted on the webmail with the sender correctly displayed in the column. It seems that the problem lies between the web and where it appears in Thunderbird.

  Help, please!

  Go to your address book and find the entrance to PayPal. Delete the name of this contact. It displays the name of the person where you first saved the contact. No doubt when you have selected to always display content from this sender.

• Copy the data from two rows together in a new line

  Hello everyone.

  This is the current situation. The lines STATE_1 and STATE_2 contain different information separate.

  In the past data were recorded at random in one of these lines.

  It's the state table:

  2	11	Mr. Smith, no answer.	Wait until December
  3	11	Pls Create PO.	Old PO has been cancelled
  4	5	No access to the system.

  Now, everything must be recorded in the STATE_3 void, but I also need than the old entries from the past which must also be copied together in STATE_3

  Like this:

  ID	Cust_id	STATE_1	STATE_2	STATE_3
  1	88	Customer is waiting.	Call since yesterday.	Customer is waiting. Call since yesterday
  2	11	Mr. Smith, no answer.	Wait until December.	Mr. Smith, no answer. Wait until December.

• Is it possible to have the audio from two different sources and routed to separate outputs at the same time?

  I currently have a string of the guitar signal electric-Rocksmith Real Tone cable - ASIO 4 all help IK Multimedia Amplitube 3.   I would like to know if I could also watch DVD with her while the implementation of the programme of Amplitube with sound.  It would be great that I use the DVD for guitar and play at the same time.   I don't have the signal of two merged as one.  In my mind, I should be able to disable the ASIO devices and use them with DirectX as usual.  I could send the ampitube signal to the headphones and use external speakers for the guitar signal, and use the lessons of speakers for the DVD (or maybe YouTube) laptop on board.

  Is this possible?

  How can I do?

  Yes.  For example, I have my Skype phone calls go to my helmet (normal just plugged in the headset) while my media player plays my speakers.  You can choose your default communication or multimedia devices with a right click on the volume control icon and choosing "playback devices".

  Other programs can also be built to be "to the output current" and allow you to choose the output too.
