• Updated with the values in the same table, for other records corresponding to conditions

  Hi Experts,

  Sorry do not provide the structure of the table (it is a simple structure)

  I have a requirement where I need to update the columns of a table based on the same table with some match empid and date values. If the date and empid match so I have these values to any other folder and update of one who is not having details of Office . I need the Update query

  Before the update my array of values is as below

  Sort_num Emp_id Bureau start_date

  1 101 AUS 01/01/2013
  2 101 01/01/2013
  3 101 15/01/2013
  4 103 USA 01/05/2013

  7 104 FRA 01/10/2013
  8 104 10/01/2013

  Thanks in advance

  I don't have the time to create the table with the data, but basically, you should be able to code the following text

  update one table

  Office set = (select desktop in table b where b.emp_id = a.emp_id)

  and b.start_date = a.start_date

  and b.office is not null

  )

  where is ([as well as overall query])

  and a.office is null

  In my opinion, who will do the trick.

• Compare several records in the same table

  Hello, I m writing a bat file so I can export information that I question.
  
  I have an automatic integration which checks from time to time if there is no new client´s and generates a trigger.
  If an error levonorgestrol I the process is repeated until the client is located in the database.
  I can't create tables or change the structure.

  Could you please help me?

  Hello

  It works very well with my data.
  What data do you use? After a few lines of sample data (CREATE TABLE AS executable... or INSERT... statements are best) that give you wrong results.

  Make sure that everything is spelled correctly.
  For example, roughly halfway through the query, you say

  and io.status = 'Erro' 
  

  and at the end you say

  having max(decode(io.status, 'Error', 1, 2))  ...
  

  That is the same ("Error" or "Error") in both places?

• If I have the two LOV in the same table then how to connect when I select first and second LOV value also change?

  Mr President

  If I have the two LOV in the same table then how to connect when I select first and second LOV value also change?

  My two fields are FLOW AND DR_NAME

  FLOW = ACCT_ID

  DR_NAME = ACCT_NAME

  I created with success of LOV for these fields.

  First LOV gives acct_id in the debit field and second LOV gives the value of acct_name to dr_name.

  How can I report these lov, it's that when I change my acct_id then acct_name also change

  I have these two tables

  CREATE TABLE "NOM"  (
    "ACCT_ID" VARCHAR2(7) NOT NULL ENABLE, 
    "ACCT_NAME" VARCHAR2(50) NOT NULL ENABLE, 
    "O_BAL" NUMBER(13,2),

• Make a column based on another value of the column in the same table

  JDev 11.1.1.6.0

  It may be a silly question but I'm stuck

  I need to conditionally return a column that said Condition is as if the value in the other column of the same table B is equal to F. I should make A column only when this condition is met. I tried the following code:

  	< af:column sortProperty = "PhoneNumber1."
  	sortable = "false".
  	headerText = "#{bindings." A.hints.PhoneNumber1.label}.
  	ID = "c146.
  	rendering = "#{rank." PhoneNumber1ResponseFlag eq 'F'} ">"
  	< af:outputText value = "#{rank." PhoneNumber1}.
  	ID = "ot130" / >
  	< / af:column >
  	< af:column sortProperty = "PhoneNumber1ResponseFlag."
  	sortable = "false".
  	headerText = "#{bindings." B.hints.PhoneNumber1ResponseFlag.label}.
  	ID = "c80" rendered = "true" >
  	< af:outputText value = "#{rank." PhoneNumber1ResponseFlag}.
  	ID = "ot129" / >
  	< / af:column >

  The data presented in the table for the PhoneNumber1ResponseFlag column are F. Still my condition does not work.

  Well, I've finally sorted it myself by managed bean.

  Here are the steps I followed:

  1. Wrote a new bean managed.
  2. Added a Boolean variable called flag and made to true when the "'PhoneNumber1ResponseFlag ' current line attribute is equal to F."
  3. Changing the property made column on this indicator.

• How to update columns with the value of other lines in the same table

  Hello
  
  I use Oracle 11.2, I'd use SQL statements to update a column based on values in other rows in the same table. Here are the details:
  
  create table TB_test (number 4 myId, crtTs date, date of MDPU);
  
  insert into tb_test (1, to_date ('20110101', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110201', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110301', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110901', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110902', 'YYYYMMDD'), null);
  
  After you run the SQL code, I would like to have the following result:
  
  1, 20110101, 20110201
  1, 20110201, 20110301
  1, 20110301, null
  2, 20110901, 20110902
  2, 20110902, null

• update to column values (false) in a copy of the same table with the correct values

  Database is 10gr 2 - had a situation last night where someone changed inadvertently values of column on a couple of hundred thousand records with an incorrect value first thing in the morning and never let me know later in the day. My undo retention was not large enough to create a copy of the table as it was 7 hours comes back with a "insert in table_2 select * from table_1 to timestamp...» "query, so I restored the backup previous nights to another machine and it picked up at 07:00 (just before the hour, he made the change), created a dblink since the production database and created a copy of the table of the restored database.
  
  My first thought was to simply update the table of production with the correct values of the correct copy, using something like this:
  
  
  Update mnt.workorders
  Set approvalstat = (select b.approvalstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  where exists (select *)
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  
  It wasn't the exact syntax, but you get the idea, I wanted to put the incorrect values in x columns in the tables of production with the correct values of the copy of the table of the restored backup. Anyway, it was (or seem to) works, but I look at the process through OEM it was estimated 100 + hours with full table scans, so I killed him. I found myself just inserting (copy) the lines added to the production since the table copy by doing a select statement of the production table where < col_with_datestamp > is > = 07:00, truncate the table of production, then re insert the rows from now to correct the copy.
  
  Do a post-mortem today, I replay the scenario on the copy that I restored, trying to figure out a cleaner, a quicker way to do it, if the need arise again. I went and randomly changed some values in a column number (called "comappstat") in a copy of the table of production, and then thought that I would try the following resets the values of the correct table:
  
  Update (select a.comappstat, b.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi - this is a PK column
  and a.comappstat! = b.comappstat)
  Set b.comappstat = a.comappstat
  
  Although I thought that the syntax is correct, I get an "ORA-00904: 'A'. '. ' COMAPPSTAT': invalid identifier ' to run this, I was trying to guess where the syntax was wrong here, then thought that perhaps having the subquery returns a single line would be cleaner and faster anyway, so I gave up on that and instead tried this:
  
  Update mnt.workorders_copy
  Set comappstat = (select distinct)
  a.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi
  and a.comappstat! = b.comappstat)
  where a.comappstat! = b.comappstat
  and a.workordersoi = b.workordersoi
  
  The subquery executed on its own returns a single value 9, which is the correct value of the column in the table of the prod, and I want to replace the incorrect a '12' (I've updated the copy to change the value of the column comappstat to 12 everywhere where it was 9) However when I run the query again I get this error :
  
  ERROR on line 8:
  ORA-00904: "B". "" WORKORDERSOI ": invalid identifier
  
  First of all, I don't see why the update statement does not work (it's probably obvious, but I'm not)
  
  Secondly, it is the best approach for updating a column (or columns) that are incorrect, with the columns in the same table which are correct, or is there a better way?
  
  I would sooner update the table rather than delete or truncate then re insert, as it was a trigger for insert/update I had to disable it on the notice re and truncate the table unusable a demand so I was re insert.
  
  Thank you

  Hello

  First of all, after post 79, you need to know how to format your code.

  Your last request reads as follows:

  UPDATE
    mnt.workorders_copy
  SET
    comappstat =
    (
      SELECT DISTINCT
        a.comappstat
      FROM
        mnt.workorders a
      , mnt.workorders_copy b
      WHERE
        a.workordersoi    = b.workordersoi
        AND a.comappstat != b.comappstat
    )
  WHERE
    a.comappstat      != b.comappstat
    AND a.workordersoi = b.workordersoi
  

  This will not work for several reasons:
  The sub query allows you to define a and b and outside the breakets you can't refer to a or b.
  There is no link between the mnt.workorders_copy and the the update and the request of void.

  If you do this you should have something like this:

  UPDATE
    mnt.workorders     A      -- THIS IS THE TABLE YOU WANT TO UPDATE
  SET
    A.comappstat =
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B   -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  WHERE
    EXISTS
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  

  Speed is not so good that you run the query to sub for each row in mnt.workorders
  Note it is condition in where. You need other wise, you will update the unchanged to null values.

  I wouold do it like this:

  UPDATE
    (
      SELECT
        A.workordersoi
        ,A.comappstat
        ,B.comappstat           comappstat_OLD
  
      FROM
        mnt.workorders        A      -- THIS IS THE TABLE YOU WANT TO UPDATE
        ,mnt.workorders_copy  B      -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
  
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    ) C
  
  SET
    C.comappstat = comappstat_OLD
  ;
  

  This way you can test the subquery first and know exectly what will be updated.
  This was not a sub query that is executed for each line preformance should be better.

  Kind regards

• Comparing the same tables of two schemas

  I had already posted a similair on this thread. So, I thought I would start a new thread on this to avoid confusion
  
  I want to generate a report that shows the difference in the data type of the columns in the same table in two different patterns.
  
  The query using LESS shows the difference below.
  
  

  create table SCOTT.mytab1 (empid number);
  create table HR.mytab1 (empid varchar2(34));
  
  
  SELECT   table_name, column_name, OWNER schema, data_type
  FROM     dba_tab_cols where owner = 'SCOTT'
  AND TABLE_NAME = 'MYTAB1'
  MINUS
  SELECT   table_name, column_name, OWNER schema, data_type
  FROM     dba_tab_cols where owner = 'HR'
  AND TABLE_NAME = 'MYTAB1'
  
  Result:
  TABLE_NAME      COLUMN_NAME     SCHEMA     DATA_TYPE
  --------------- --------------- ---------- ------------
  MYTAB1          EMPID           SCOTT      NUMBER

  But, since it is a report, I want to see the form of results the two schemas that has column of different data types with the same names of table
  
  Expected results:

  TABLE_NAME      COLUMN_NAME     SCHEMA     DATA_TYPE
  --------------- --------------- ---------- ------------
  MYTAB1          EMPID           SCOTT      NUMBER
  MYTAB1          EMPID           HR         VARCHAR2

  Anyway I could do this?

  Why not get a single line with two types of data:

  select a.table_name, a.column_name, a.data_type schema1_type, b.data_type schema2_type
  from all_tab_columns a, all_tab_columns b
  where a.owner = 'SCOTT'
  and b.owner = 'HR'
  and a.table_name=b.table_name
  and a.column_name=b.column_name
  and a.data_type!=b.data_type;
  

  This extracted single query columns present on the two schemas but with different data types. These columns only on one of the two schemas are not extracted.

• Name of the file and the measure in the same table?

  Hello

  I wrote the following VI which opens each image file in a folder and measure a certain size on the image. He then puts the result in a table.

  The table has a column and N lines since I N images in my folder. How can I change this VI so that it puts the name of the file in the same table as well as the measurement?

  I want the table to look like:

  File1 measurement1

  File2 GCA2

  ...

  and so on.

  Currently, it just shows

  measurement1

  GCA2

  ....

  and so on.

  The VI are:

  You cannot use the Table Express. Like the properties page says: this is for digital data. You will need to use a bit of real LabVIEW to create the table. A table is simply a string 2D array. Convert the digital chain, build an array of 1 d of the filename and numberic strings and use a shift register to build a 2D array. Something like the code below.

  

• Insert select on the same table: possible without side effects?

  I have a very large table T1 containing millions of records. I need to treat its lines and create a few new lines based on selection.

  Table T1 contains events and one of them, with the code 100, is created by the further development of other events inside the table.

  My code is as follows:

  insert /*+append */ into T1 (code,...) values (100, c1,c2,...)
  select c1,c2... from T1 where (code=20 or code=10) and <other conditions>...
  
  

  as you can see I'm extract T1 lines to insert again in T1 with a different code and I use the direct path in order to get good performance.

  My fear is: choose is made from the same table I risk data loss? In general it is a good practice? Or is it better to create another table?

  Hello

  No I don't think that there may be loss of data. But that may depend on the behavior of the application and your where clause.

  I will explain how it is treated, so you can see if it's ok:

  1. the table is locked because of the insert add, (as)

  2 lines are read by select and make compatible from the State that was at the beginning of the query - 1.

  3 rows are inserted at the end, after the high-water line

  4 columns for new lines are sorted to be merged in the index

  5. high watermark is adjusted - visible new lines and lock is released

  Note that 2. and 3. occur at the same time: rows are inserted all read.

  Note that anyone can choose in the table during the operation - they see the changes committed only - if the State 1.

  all other DML are waiting for the lock being released, and will see new ranks and then

  If you have things that prevent the direct-path insert, append the hint will be ignored. So, if you must rely on close to 1. then the best lock explicitly with table lock. But I don't think that you need.

  Kind regards
