• Exchange of values between two columns

  I have a MEMBERS_SYSTEMS_ID table with three columns ID, B1, B2.

  You cannot update a variable as part of an update, only columns in the table. And, in fact, you don't have an intermediate variable, just do the update directly as:

  SQL> SELECT * FROM t;
  
          ID DESCR1     DESCR2
  ---------- ---------- ----------
           1 Descr2     Descr1
           1 Other2     Other2
           2 Two1       Two2
  
  SQL> UPDATE t
    2  SET descr1 = Descr2,
    3      descr2 = descr1
    4  WHERE id = 1;
  
  2 rows updated.
  
  SQL> SELECT * FROM t;
  
          ID DESCR1     DESCR2
  ---------- ---------- ----------
           1 Descr1     Descr2

• How to highlight the minimum value in a column?

  I need to highlight the lowest value in each column in my spreadsheet. I try to use the conditional nail, but I can't find a function to work as I need.

  One way would be to calculate the minutes in a cell of a footer row, select the cells in the body of the column and apply conditional highlighting like this:

  

  You must click on the chip address first, and then select the comparison cell, A8 here, then be sure to keep the row and column.

  

  The A8 from the example formula is = MIN (A).

  The result is a bold 2 (not shown in the screenshots).

• I have a column with two values, separated by a space, in each line. How to create 2 new columns with the first value in a column, and the second value in another column?

  I have a column with two values, separated by a space, in each line. How do I create 2 new columns with the first value in one column and the second value in another column?

  Add two new columns after than the original with space separated values column.

  

  Select cell B1 and type (or copy and paste it here) the formula:

  = IF (Len (a1) > 0, LEFT (A1, FIND ("", A1) −1), ' ')

  shortcut for this is:

  B1 = if (Len (a1) > 0, LEFT (A1, FIND ("", A1) −1), ' ')

  C1 = if (Len (a1) > 0, Member SUBSTITUTE (A1, B1 & "", ""), "")

  or

  the formula of the C1 could also be:

  = IF (Len (a1) > 0, RIGHT (A1, LEN (A1) −FIND ("", A1)), "")

  Select cells B1 and C1, copy

  Select cells B1 at the end of the C column, paste

• Query, which returns lines adding up to a value in a column

  Hello

  You are looking for an application that will process and return only the many lines that add up to a special value on a column value.

  for example

  ID name date_joined allocated salary

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

  1 Tom January 1, 2010 1000 5000

  Dave 2 3000 5000 February 1, 2010

  3 Cindy 1000 5000 01-apr-2010

  4 Ian 01-mar-2010 1000 5000

  5         Matt          10 -jan-2010 1000-5000

  Return the lines where wages adding upto or beyond the value allocated to 5000, order by date_joined or more former employee first.

  The query should return:

  ID name date_joined allocated salary

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

  1 Tom January 1, 2010 1000 5000

  2         Matt          10 -jan-2010 1000-5000

  We do not want to deal with or include other lines summarizing calculation, would instead add first, if deficit adds to the line.

  Tried with lead, windowed with range UNLIMITED etc. that PRECEDES, that would not come up with good logic.

  I could make it work with PL/SQL, but do it in SQL turns out to be delicate.

  Thank you.

  A.

  Thanks for the input guys.

  Here, the ask is:

  1. how to treat only as lines that satisfy the "allocated" value, without treatment of all lines.

  > Thanks to Jarkko year John for the right direction.

  > RanitB thank you for your approach to the application of the model, I am not well versed with model query that I'll get to. But for the moment its not useful for me.

  2. to get only as much lines that are either less than or equal to 'assigned' value or satisfy "allocated", from less than "attributed" just beyond "allocated".

  (Sorry for the language, if its not very clear, I do not know how this fits better, following example should help demonstrate).

  I came up with the following code, although there could be best way to do it, I hope to see someone.

  {code: sql}

  create table t:

  Select object_name, join_dt, the salary of 1000 last_ddl_time, allocated 5500

  of object;

  Select

  / * gather_plan_statistics * / *.

  Of

  (select

  object_name, join_dt, salary, allocated, sofar, lag (sofar, 1, 0) over (order by join_dt) lag_sofar

  Of

  (select

  object_name, join_dt, salary, allocated,

  Salary on sofar (order by no_lig)

  Of

  (select object_name, join_dt, salary, allocated, row_number() on no_lig (order of join_dt) t) t - must do it has several join_dt even inputs (objects have same time ddl)

  )

  )

  where

  allocated > lag_sofar;

• Using the value of the column of the report in view state

  Hi all

  I have a little trouble as long as you report column. Here's the problem I have face.

  I have a classic report in apex5 (universal theme). Please find the page here https://apex.oracle.com/pls/apex/f?p=62495:5:

  I want to have a condition that SAL column should appear only if DEPTNO! = 10. For this, I put a conditional display for SAL column that "point value / expression 1 column! Expression 2 ="and #DEPTNO # expression1 and expression2 10. But this doesn't seem to work. Can someone help me understand the issue.

  Note: I want to view only the column of the report, not the page item in the condition.

  Thank you

  It is not possible to report baseline values in the State of the reference column. It would be unwise to do so: how APEX can determine if the column should be included or not until all rows are retrieved?

  Note: I want to view only the column of the report, not the page item in the condition.

  Why? In the example given, this is the correct (and more effective) approach. If the condition must be based on the expected query results, then use a Exists (SQL query returns at least one row) or NOT Exists (SQL query returns no line) condition.

• How to map the entered value of attribute column to another attribute in the table for each row.

  Hi Experts ADF,

  JDev 12 c.

  I create a button and a table below. If the user clicks on the button create, I invoke CreateInsert. The new line now appears as an editable fields.

  So I suppose I have a column that is displayed in editable mode. If the user enters values in that. Has another column B whose value is not displayed in the UI must have the same value as the column.

  This occurs for each row added. During the click on save if user entered 2 in column A, then the value in column B must be same 2.

  Thank you

  Roy

  There is more than one way, for example:

  Generate ViewRowImpl Java class (with generate audited accessors) you will get for an attribute setter.

  Change the Set accessor to set the attribute B (IE, calling setAttribute ("B", value)) after setting a value

  OR, write valueChangeListener for inputText representative and set the B attribute to the same value

  Thank you

  Renon,

  When you write code, try to understand what makes each line. (If you don't understand all the lines, feel free to ask)

  row.setAttribute ("ItemStatus", row.getAttribute ("ItemStatus"));

  What do you think that the above line done? You try to get the value of the attribute and trying to put the same value. How is it, that will have an impact?

  You need to do 2 things.

  1. change the insertRecord method and the State of return of this method.

  Change the definition of the function:

  public String InsertRecord (String itemstyle, String itemcust, String itemsize, String itemcolor, String ordrno,

  String desc)

  Add a return statement at the end after validation.

  TR.Commit ();

  return the situation;

  }
  

  2 accept that status in CO and set the value to the attribute details VO.

  String status = (String)am.invokeMethod ("InsertRecord", param);

  row.setAttribute ("ItemStatus",status);

  I hope this helps.

  See you soon
