• Update multiple columns from multiple tables in a single UPDATE request

  Hello

  I'm trying to figure if I'm heading in the right direction.

  I want to update multiple columns from multiple tables in a single UPDATE request. Also, I would like to update multiple columns in a table from the tables.

  Scenario 1

  UPDATE Table2, Table 3
  SET T2.Column1 = T1.Column1 
  ,T2.Column2 = T1.Column2
  ,T3.Column2 = T1.Column2
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T1.id = T2.id
  and T1.id = T3.id
  
  

  Scenario 2

  UPDATE Table3
  SET T3.Column1 = T1.Column1 
  T3.Column2 = T1.Column2
  ,T3.Column3 = T2.Column3
  ,T3.Column4 = T2.Column4
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T3.id = T1.id
  and T3.id = T2.id
  
  

  Hello

  For scenario 1, you must write separate instructions UPDATE table2 and table3.

  To guard against someone else change one of these tables while you act so you can copy all relevant data in a global temporary table and update this global temporary table table3.

  ENGAGE only when two tables have been changed.

  You can write a procedure or an INSTEAD OF trigger to do all this.

  For scenario 2, you can reference many tables that you need when new table3.  It might be more efficient and simpler to use the MERGER rather than UPDATED.  For example:

  MERGE INTO table3 dst

  WITH THE HELP OF)

  SELECT t1.id

  t1.column1

  t1.column2

  t2.column3

  t2.column4

  FROM table1 t1

  JOIN table2 t2 ON t1.id = t2.id

  )             src

  WE (dst.id = src_id

  WHEN MATCHED THEN UPDATE

  SET dst.column1 = src.column1

  dst.column2 = src.column2,

  dst.column3 = src.column3,

  dst.column4 = src.column4,

  ;

• How to update a record, if it is a composite key (primary key is based on two columns) in the OPS? page?

  Hello

  Actually I got to know this update of a record must be made when the primary key is based on two columns.

  Previously, I used SPEL for a column. It was working fine.

  But I came to know that regardless of the folder I try to update, it was the update page is coming up with the first combination of the record.

  As if RC 131

  RC 124

  RC 125 are the records.

  If I click on update of RC 124 also, the update page is coming up with RC 131 values as it is the first.

  So I understand that the SPEL should be based on two parameters, because it is a composite key.

  How to do?

  Please let me know if you don't understand the problem.

  Thank you.

  Wow!

  I got it.

  Thank you brothers, always a hope that you could help me

• update of two columns at once

  HI can update us two columns at once by the regular update by mentioning two where clauses with respect to columns

  The where clause decide which set of lines will be updated.
  For example, if the set of rows is not the same for your two columns you must use two sentences--update.
  If the rowset is the same for your two columns you can use a single update statement (but then the where clause will be the same).

• Need add/update two records on click on the create/update button

  I have a table with 5 columns

  1 ID - primary key

  2 name

  3. address

  4 CARB

  5 KADER

  Now whenever I do an insert in this table to this table I have to add two rows, as shown below:

  1st row - (name1, Add1, 717, 717)

  2nd place - (name1, Add1, 515, 515)

  Name and address values are entries of the screen and the CARB & KADER values are fixed (717 or 515). So for each click on the button create two records needs to be inserted.

  Even when I update to say record particular Carb - 717 & kader-717, I must also update other file too Carb-515 & kader-515. For each click on the update button, so I need to update two records.

  Please tell me as to how I will do this

• Can we use two columns AS a command

  Dear all,
  
  Please suggest
  
  I have two columns of different table and I want to make a general query selection of values in a table based on one exact string of others. Please find the following query:
  
  Select a.col1, b.col2
  FROM table1, table2 b
  where a.clo3 like b.col4;
  
  Now a.col3 values can be like "asbd %" or "qw %" or "% zx.
  where, as in b.col4 it will be asbd or qw or zx.
  
  Please suggest what I would do.
  
  Thanks in advance.
  Ankit Rana

  Hi, stone.

  Yes, you can use LIKE this way.

  Do not forget that AS is asymmetric:

  x LIKE y
  

  is usually not the same as

  y LIKE x
  

  because wildcard characters ('%' and '_') have a special meaning in the right operand, which is the expression that comes after LIKE.

  So, it seems that you have to reverse the operands of TYPE:

  where   b.col4  like a.clo3;

• Validation of feature templates ADF - how to validate two columns using a query?

  Hello
  
  I'm trying to implement a validation for one of the fields in an ADF entity object. The logic is essentially as follows:
  
  database has a table - TABLE1 with columns COL1 and COL2 - two columns also exist on the TABLE2.
  
  When the user enters a value for create or update values TABLE1, before user could save I need to validate the following:
  
  This combination column1 and column2 entry corresponds to a line of TABLE2. (basically, they must exist as a line of TABLE2).
  
  I don't know how to do this with my current version of JDev (10.1.3.4), but I hope that it is possible.
  
  Thanks in advance.

  You can write a validator method at EO level that uses a viewObject with two binding settings to find the specific row in the other table.

• Update one column of the other

  Hi guys,.
  
  I have two columns in a table, FIRSTNAME and LASTNAME. Currently, the firstname and lastname appear in the column "Firstname". I would separate the name of this column and insert in the "LASTNAME" column
  
  For example, here is what I currently have:
  
  Line: -.
  
  First name last name
  
  Peter Andre
  James Dean
  Men watch
  Jenna Klare
  James Smith
  Tina Adams
  Blair Witch
  
  
  Currently, my "Lastname" column is empty. I want to update the table to insert lastname in the "First NAME" field in the "LASTNAME" column, so the output will look like:
  
  First name last name
  Peter Andre
  James Dean

• Validation of a region defined as a QUERY SQL type (updated report)

  Hello
  
  I am trying to perform validation on a region defined as type of QUERY SQL (editable report). The report has two columns.
  One of the columns is a Select list and I want to make sure that the user can select the same value twice
  in the report. For example, if the selection list has 5 values A, B, C, D, E, I don't want a user to be able to select
  B twice in the report. Will it use javascript to perform validation? If Yes, could someone provide some guidance on
  where to embed the javascript? Are there other alternatives than javascript? I create an element that came from a sql query
  counts the number of lines where the value of the column is the same. I then used the item in my validation logic. The problem with this logic
  is that a user can enter the same value and it is not until the 3rd attempt to select the same value that the validation works using the number of lines which is why I think that I need to somehow capture the value of the selection list when a user selects and then compare it to what is already in the database column Select.
  
  I hope that my question and explanations are clear.
  
  Thanks in advance for your help,
  
  Michael

  Hello

  This can be managed using javascript or a validation of the page. Here is an example of use of javascript: [http://htmldb.oracle.com/pls/otn/f?p=267:7]

  To do this, I have:

  1 - a model of button which does not send the page but just runs javascript. The model will depend on your theme, but should include:

  <a href="#BUTTON_ATTRIBUTES#">#LABEL#</a>
  

  If #BUTTON_ATTRIBUTES # appears on the template, delete it as we need it only once. You must create a new button model based on a copy of your existing across models, shared components. Normally, he would show href = "" #LINK # "-we do not want that this would become doSubmit('buttonname')." If your model does not use tags for buttons, you might need to create one from scratch.

  2 - I have updated the button on my page to use this template and then assign the setting button attributes:

  javascript:check();
  

  3. in the header of the HTML page, I added:

  <script type="text/javascript">
  function check()
  {
   var e = 0;
   var f = document.getElementsByName("f02");
   var k1;
   var k2;
   var v1;
   var v2;
   if (f)
   {
    for (k1 = 0; k1 < (f.length - 1); k1++)
    {
     v1 = f[k1].value;
     for (k2 = (k1 + 1); k2 < f.length; k2++)
     {
      v2 = f[k2].value;
      if (v1 == v2)
      {
       e = 1;
      }
     }
    }
   }
   if (e > 0)
   {
    alert("Duplicates found!");
   }
   else
   {
    doSubmit("SUBMIT");
   }
  }
  </script>
  

  In this example, SUBMIT is the name of the button and "f02" is the name attribute of the select list items that we want to check - change these needs by your page.

  Now, when the Submit button is clicked, instead of directly submit the page, the javascript function is called. This function loops through each selection list and gets its value. Then, he compared it to the remaining items. If there is a match, the e flag is set to 1. After all the items have been verified, if e is not 0, then a message appears. Otherwise, the page is sent.

• iBooks/iPad two columns per page

  Since this morning after an update to the iPad, iBooks is showing the book pages in two columns instead of a full page, from left to right.  How can I change this back to a page on the screen?

  I saw that too. Stupid solution. Increase your font a to the top of the smallest.

  The smaller police apparently goes into two columns.

• SQL monitor help with column of chronology

  

  In the report attached to sql, in the timeline column means the whole last 3 began simultaneously and hash join is the first exploited who started?

  my understanding is 'index range scan' should start first and give the data to "Single Partition range". Only once this step completed, he should 'TABLE ACCESS Full'. Isn't this correct?

  Thanks for your time!

  Your description is correct - and I think that you just have to allow some defects in the rounded, graphic display of errors and inconsistencies in what is "the order of execution.

  If it is still possible, you can watch dbms_sqltune.report_sql_monitor output text () as numbers COULD clarify the sequence - on the other hand, the granularity of the timer is not very fine.

  You may find that the chronology of hash join begins before the access times two table - which highlights the problem of "means to launch an operation."  The subroutine "do a hash join" must begin before the two tablescans, on the other hand the mechanism 'return rowsource to parent' cannot start until after the second table access began to return the hash join lines.

  Another sign of the available seeds, of course, is that the select statement does not seem to have started until a few seconds after the hash join has started!

• using outer joins if the two column is null? Use only (+)

  Hi all

  See what returns the count? You have grouped according to TR_NO and TL_NO_ID. You must take into consideration the TL_NO_ID just put COUNT (TR_NO) does not increase the NUMBER of the whole group. To get the NUMBER on the whole group, I used the analytical function and did. Like this, see the number of the analytical function here
