• Validation form column against the value of another Table

  Hello

  I'm new to this forum, so please bear with me a bit!  I only have a small amount of writing PL/SQL experience, and I've never written Javascript or JQuery before.  I am an Oracle DBA and I coding experience C and PERL, so I have a strong technical background.  But I need some advice on the best way to approach a problem.

  I have an application of data base in Oracle Apex (version 4.2) with a tabular form on a table: Let's say that #1 with the conditions of licence 1 a, 1 b, and1C.  I have to make sure that the value entered in col B is not greater than the value of a column in another table (for example table #2 pass 2 (a).  From a conceptual point of view, the amount of money available is in the #2 table, and my tabular form lines are an act of spending money (such as orders or invoices), so I have to make sure that we spend more that we have.  Who is?

  Does anyone have tips for the best way to do it?  I'm figuring that the biggest problem here is perhaps to account for people who enter multiple lines in the form of tables at the same time, right?  So, if a person is entered 3/invoices, I need a total to ensure that they do not have spend more than we have in the #2 table.

  I really appreciate your help!

  Best regards

  Ah, I was not totally with you on this charge then. My validation works overall, but it totals the amount for each line, regardless of the task. Okay - who was not totally my solution but more a demonstration of the technique that you can use to validate your tabular presentation in this way.

  You could solve this issue with a safe collection, or with a table plsql where you add an entry for each task name and keep the amount stored in there.

  Anyway, it would be better for you to spend a little time on playback on the plsql collections or collections apex!

  • 5 use PL/SQL of Collections and records
  • APEX_COLLECTION

    l_amount NUMBER;
    l_max NUMBER;
  BEGIN
    -- F02 is the taskname
    -- F03 is the amount
    -- adapt to your situation!
    FOR i IN 1..apex_application.g_f02.count
    LOOP
      l_task := apex_application.g_f02(i);
      l_amount := apex_application.g_f03(i);
      IF NOT t_taskamount.exists(l_task) THEN
        t_taskamount(l_task) := l_amount;
      ELSE
        t_taskamount(l_task) := t_taskamount(l_task) + l_amount;
      END IF;
  
      -- it's not the best idea to perform a select each time and could be
      -- done better but for the sake of the example it's fine
      -- not too bad either if the rowcount is small.
      SELECT maxamount
        INTO l_max
        FROM table2
       WHERE taskname = l_task;
  
      IF t_taskamount(l_task) > l_max THEN
        -- returning will stop further processing and throw an error message as soon as a budget has been overrun
        -- it might or might not be required behaviour but that's up to you
        RETURN 'The max amount ('||l_max||') for task ' || l_task ||' has been exceeded. Reduce the total amount on associated tasks!';

• update of NULL in the column with the values of the adjacent column

  Examples of data

  with test_data as
  (select 1 as one, null as two, 2 as three,5 as four, 6 as five, null as six from dual
  union all
  select 1 as one, null as two, 2 as three,5 as four, 6 as five, null as six from dual)
  select * from test_data;
  

  This is one of those cases, the case may be where any value of a column can be null

  or two similar columns can be null. If the column is null then I want to update the adjacent column

  average value of the column, if the first column is null so I want to take the next non-null column and update, if the last column is null

  so I want to take prev not zero column and to update.

  In this case would be my expected output

  Un	Two	Three	Four	Five	Six
  1	1.5	2	5	6	6
  1	2	3	5	6	6

• Fill two empty columns with the values in a column (all in the same table)

  Can someone point me in the right direction? I want to fill the column prefix and suffix with the AcctNum data.
  
  "Prefix is the part of the number before the '-' and the suffix is everything after the '-'. '. Write a SQL command to fill the column prefix and suffix.
  

  *Accounts* 
  
  AcctNum   Prefix   Suffix

  123-0098
  F3377-D

  F3377-D
  X089-057
  X089-058
  3-009712

  That's what I came with, but it does not work because it is basically putting multiple values into a single cell:

  update accounts
       set prefix=(select substr(acctnum, 1, instr(acctnum,'-')-1) from accounts),
       suffix=(select substr(acctnum, instr(acctnum, '-')+1) from accounts)
       where acctnum=(select prefix||'-'||suffix from accounts);

  I want this query is incredibly easy and I have forget something. Any help is greatly appreciated.

• Add column if the value in another column

  How can I add a column as column name 'YES_OR_NO.
  
  SELECT VALUE_ID IN THE TABLE TABLE_NAME
  
  VALUE_ID
  ---
  1
  2
  3
  4
  5
  
  Now, I want to create another column in the sql query called YES_OR_NO and that if there is a value in VALUE_ID then column YES_OR_NO must say 'YES' if there is no value in the column VALUE_ID of this line YES_OR_NO must say 'NO '.
  
  or just a way for her also to work would be to show this new column or not if a value in another column of table_name_2 (this would be ideal)
  If new column yes_or_no and fill by a Yes or a no if a value is found in another table

  Assuming that you are on a version that supports the CASE expression:

  SELECT VALUE_ID

• PDF form: fill in the field with the value of another field

  Hello

  I have a PDF form that one of our employees has to be completed on a regular basis.

  There is a 'product' - text field, which is present on the form several times, which will contain the same information.

  From now on, my colleague has fill all these these one by one manually. But with the copy - paste, it doesn't take more than a few seconds.

  However, to facilitate work a little, I want to it to be able to simply fill out one of the fields (can be a specific, must not be dynamic) and all the other 'product' - fields automatically takes the value of the field of this first.

  How can I accomplish this?

  I noted the possibility of JavaScript controls.

  I am familiar with basic JavaScript, however never used it for PDF files.

  Any help and pointers would be appreciated.

  Thank you very much.

  This isn't a problem with script. Just give each field of the same name. Once the field names are the same, a change in one will be to another. For some reason that it does not work with standard HTML forms, probably the reason why you ask.

• 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

• Documentation about adding column with the DEFAULT value.

  Hello
  
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/statements_3001.htm#i2198241
  
  < quote >
  If you add a column, then the initial value of each row in the new column is NULL unless you specify the DEFAULT clause. In this case, Oracle database updates each row in the new column with the value specified for the DEFAULT value. This update operation, in turn, triggers AFTER UPDATE triggers defined on the table.
  < quote >
  
  I am not able to understand the emphasis on the part AFTER UPDATE while the column with DEFAULT values addition triggers both BEFORE and AFTER triggers defined on UPDATE.
  
  According to the documents of 11 g
  
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_3001.htm#i2133105
  
  n.m. (u) r only changes with the NON NULL columns, but focus on AFTER UPDATE is still there. No trigger defined on the fire of the update in this case.
  
  This insistence is intended? If not, IMO, it should be changed.
  
  Kind regards

  Hi Sissi. After further discussion, we have added some information about a change in behavior. Here is what says the next version of the doc:

  When you add a column, the initial value of each row in the new column is null.

  * If you specify the DEFAULT clause for a column NOT NULL, then the default value is stored as metadata, but the column itself is not populated with data. However, the following queries that specify the new column are rewritten so that the default value is returned in the result set.

  This optimized behavior differs from earlier versions, when as part of operation ALTER TABLE Oracle database updated every line in the newly created with the default column and then fired defined update triggers on the table. In this release, no trigger is triggered because the default value is stored only in the form of metadata.

  * If you specify the DEFAULT for a nullable column clause, then the default value is added to existing lines under this ALTER TABLE statement, and any update triggers defined on the table are activated. This behavior also means if you change a NOT NULL column with a default value to be nullable.

  Hope that helps to clarify the matter further.

  Kind regards

  If seen many answers on how to make the field itself disappear based on value, but I did find something that causes another field or shape appear or disappear depending on the value of another field.
