• Question of assignment to the value of the variable ODI

  Hello

  I have a value assigned question of one ODI variable to another

  Scenario:

  I have 2 variables var1 and var2 and you want to assign the value of var1 and var2. Assuming that var1 has a value of 11

  I want in the end

  var1 = var2 = 11

  What do I do?

  At the project level, stated 2 variables var1 and var2 alphanumeric two, without history

  In the package

  (1) I said as a refreshment var1 variable assigned a value via refreshing option

  (2) declared a second SET variable var2

  (3) assigned (tried various options) value with different options

  # < Project code > .var1

  "# < Project code > .var1.

  "# < Project code > .var1.

  < % = odiRef.getOption ("var1") % >

  The value of VAR2 attaches not to the value of VAR1.

  Hello

  I am sure that I answered a question similar at least twice in recent months. Please do a search...

  However do this changes

  • put your variable to the most RECENT VALUE
  • Rename them in capital LETTERS
  • Equip your package the following steps
    1. declare VAR1
    2. say VAR2
    3. Refresh VAR1
    4. Assign VAR2 with this #PROJECT value. VAR1

  Let us know.

  Hello

  to get the answer, we need to know what is your expected results (showing an example).

  I don't know if this is appropriate for your needs:

    SELECT trans_id, debit_credit_indicator, MAX (trans_amt) trans_amt, 'MAX' min_max
      FROM test_bank
  GROUP BY trans_id, debit_credit_indicator
  UNION ALL
    SELECT trans_id, debit_credit_indicator, MIN (trans_amt)trans_amt, 'MIN' min_max
      FROM test_bank
  GROUP BY trans_id, debit_credit_indicator
  ORDER BY trans_id, debit_credit_indicator, min_max DESC;

• How to get the value of a * Global * Application point of JS

  If we declare an element of the request, which is NOT a level of the page in question, how we get the value of this element in an Action dynamic JavaScript on a page?
  
  For example, we declare a "global" variable as an Application named DEFAULT_AJAX_SEPERATOR and set its value with a calculation of the claim "on the new Instance" a moment later, on a page of the application, we would like to get the value of DEFAULT_AJAX_SEPERATOR via JavaScript.
  
  Page* level syntax element...

  $v( 'DEFAULT_AJAX_SEPERATOR' );

  .. How does not work. I don't understand why it's like $v can only access the elements on the page. However, the APEX is clearly able to get these global values since, for example, they are available in PL/SQL blocks. Also, I know that it is on the session object, because I can see it when viewing the session.
  
  So... What is sauce secret for obtaining this value?
  
  Thank you

• formula to subtract the value of the fixed number field

  I'm new to javascript and have been unsuccessfully trying to complete what I know is a very simple task.  I have a form with 12 fields containing a sum in dollars.  "C1" field has a formula that counts the number of 12 fields contain a value.  This formula works correctly.  I want the "c2" field to display the number of fields without value.  I thought it would be simple subtract the value of "c1" of 12 to get the value of "c2", but I can't make it work.  The formula below is what I currently have in the custom calculation script window.  Any help with the drafting of a code that works would be greatly appreciated!

  var a = 12;

  var b = this.getField ("c1");

  var c = this.getField ("c2");

  c.Value = a.value - b.value;

  You must make sure that b.value is a number, not a string with a number.

  var a = 12;

  var b = this.getField("c1").value;

  this.getField("c2").value = a - b;

  See you soon

  Hello

  The string "100" comes before "2" in the sort order for the same reason that 'ALL' comes before 'B '.

  If you want to t_value a number, make a NUMBER, not a VARCHAR2 column.

  I f you can do that, then you can try to use TO_NUMBER to convert it to a NUMBER.
  but you will get an error if Island column already contains everything that cannot be interpreted as a NUMBER.

• ([JDev12c, ADF] 1) how to get the value of a field of the line currently selected in question 2) af:table: flowScope

  Hallo,

  How can I get the value of a field in the row that is currently selected in an af:table?

  I need to pass this value to a setCurrentRowWithKeyValue who took the record to display in another (by a button) called page:

  Limited workflow

  Page1 - goToPage2-> setCurrentRowWithKeyValue-> PAGE2

  I defined a managed bean flowScope for the workflow in which I created the variable 'CodeToSetPage2Row '.

  I will store the value of the field for the selected line in this variable so that I can move on to the setCurrentRowWithKeyValue.

  Could be this method OK? Ore is there any good practice to achieve this goal?

  The managed bean flowScope used to go to the stubborn task may take some values from the outside?

  The workflow defined will be executed in a dynamic region.

  Thank you

  Federico

  Federico, you cannot use a flow variable scope for this page. The region has no access to the bean. You must use a workflow for this parameter.

  To get an attribute of the currently selected line you make slide data vo of control on the page attribute. This will create a link attribute for this attribute. Once this link exists, switch to source mode and remove the component that you do not want.

  The framework passes the value of the current row in this affair of the attribute (table should be in single selection mode).

  Click on the button, you switch the binding of the attribute for the setting of task flow using a setPropertyListener.

  In the workflow, you call the setCurrentRowWithKeyValue with the parameter of workflow as the default activity.

  How to use the values of the input variables on the table select statement names?

  Hello

  Here's a way you can use dynamic SQL statements for this task:

  CREATE OR REPLACE FUNCTION IS_YDAYDATA_TO_TABLE

  (

  in_schema IN VARCHAR2,

  in_tablename IN VARCHAR2,

  in_datefield IN VARCHAR2,

  in_first_date DATE DEFAULT SYSDATE - 1,.

  )

  RETURNS INTEGER

  AS

  -IS_YDAYDATA_TO_TABLE returns 1 if in_schema.in_tablename.in_datefield

  -contains all the dates in the in_first_date of the range through included in_last_date

  - and it returns 0 if there is no such lines.

  -If in_last_date is omitted, the search only the data on in_first_date.

  -If in_first_date is omitted, it defaults to yesterday.

  -Time parts of the in_first_date and in_last_date are ignored.

  -Declaring variables

  sql_txt VARCHAR2 (1000);

  v_is_true INTEGER.

  BEGIN

  sql_txt: = 'SELECT COUNT (*).

  || 'FROM ' | in_schema | '.' || in_tablename

  || 'WHERE ' | in_datefield | ' > =: d1'

  || «AND» | in_datefield | '< >

  || 'AND ROWNUM = 1';

  dbms_output.put_line (sql_txt |) '= sql_txt in IS_YDAYDATA_TO_TABLE");  -For debugging

  Sql_txt EXECUTE IMMEDIATE

  IN v_is_true

  With the HELP of TRUNC (in_first_date) - d1

  TRUNC (NVL (in_last_date

  in_first_date

  )

  ) + 1                -- d2

  ;

  RETURN v_is_true;

  END is_ydaydata_to_table;

  /

  DISPLAY ERRORS

  If you must use dynamic SQL statements, put all the SQL statement in a single string variable, such as sql_txt in the example above.  In this way, you can easily see exactly what will be executed.  Comment out the call to dbms_output under test is completed.

  Try to write functions that will address not only the question that you have now, but similar questions that you may have in the future.  For example, now that interest you only to the verification of the data of yesterday, but later, you might want to check another day or range of days.  The above function combines the convenience of a function simple (looks like yesterday data if you don't tell him otherwise) with the power of a more complex function (you can use the same function to check any day or range of days).

  I'm sure that I'm missing out on a minor addition. Any hint on solving this would be appreciated.
  
  Thank you.

  Hello Florent.
  I have not read all your codes but from the title of your question. I think that you are not been able to get the status of the Update checkbox. To obtain the present value of checkbox, you must update 'OBJECTS' tableview to plant cells check box. For the State of the elements of this update...

  SIMPLE ALGORIGTHM
  -CLICK EVENT IS PAST IN THE CELL (BOX)
  -FUNCTION CELL_FACTORY TRIGGERS
  -YOU WILL GET THE INDEX OF THE LINE
  -UPDATE THE TABLE VIEW "ITEMS" WITH AND UPDATE THE SPECIFIC INDEX
  -THE CHANGES WILL HAPPEN THIS WAY

  Thank you

• Question from beginner on the fusion of the Recrords in the Table

  This question is about question 10-b of merger on page 3-41, it says:
  (page 3-41 "Oracle Database 10g SQL Fund. II Vol.1")
  
  Merge the data into the EMP_DATA table that is created in the lab last in the data in the table emp_hist. assume
  EMP_DATA external table data corresponds to the EMP_HIST of table, update the email column
  table EMP_HIST to match the row in the EMP_DATA table. If a row in the EMP_DATA table is not
  match, to be inserted in the tables of EMP_HIST lines are considered as corresponding whenever his first and
  family name are the same.
  
  For me, this issue is built wrong. First of all in the last lab we have not been asked to create EMP_DATA. Secondly, EMP_DATA is empty.
  Thirdly, this question asks us to merge into the table EMP_HIST while EMP_DATA is empty.
  
  Table EMP_HIST currently copied data from the employees table. Structure EMP_HIST:
  
  FIRST NAME VARCHAR2 (20)
  LAST_NAME NOT NULL VARCHAR2 (25)
  EMAIL NOT NULL VARCHAR2 (45)
  
  EMP_DATA table is empty. I created it as follows:
  
  create or replace directory emp_dir
  like 'F:\emp_dir ';
  
  drop table emp_data;
  
  CREATE TABLE emp_data
  (first name VARCHAR2 (20))
  , last_name VARCHAR2 (20)
  , email VARCHAR2 (30)
  )
  EXTERNAL ORGANIZATION
  (
  TYPE oracle_loader
  Emp_dir default DIRECTORY
  ACCESS SETTINGS
  (
  RECORDS DELIMITED BY NEWLINE CHARACTERSET US7ASCII
  NOBADFILE
  NOLOGFILE
  FIELDS
  (first name POSITION (01:20) TANK)
  , last_name POSITION (22:41) TANK
  CHAR POSITION (43:72) by email)
  )
  LOCATION ('emp.dat'));
  
  Back to our question, I've done the merger as follows:
  
  merge into e emp_hist
  with the help of emp_data d
  on (e.first_name = d.first_name)
  When matched then
  game update
  Select = d.last_name,
  e.email = d.email
  When not matched then
  Insert values (d.first_name, d.last_name, d.email);
  
  I get this error:
  
  Error report:
  SQL error: ORA-29913: error in executing ODCIEXTTABLEOPEN legend
  ORA-29400: data cartridge error
  KUP-04040: file emp.dat in EMP_DIR not found
  ORA-06512: at "SYS." ORACLE_LOADER', line 19
  29913 00000 - "error in the execution of %s legend".
  * Cause: The execution of the specified legend caused an error.
  * Action: Examine the error messages take appropriate measures.
  
  On the other hand, I said I'm going to try this:
  
  merge into emp_data d
  using e emp_hist
  on (d.first_name = e.first_name)
  When matched then
  game update
  d.last_name = select,
  d.email = e.email
  When not matched then
  Insert values (e.first_name, select, e.email);
  
  I get this error because the external table's final after its creation (no update, insert, delete authorized) as far as I know:
  
  Error report:
  SQL error: ORA-30657: operation not supported on external organized table
  30657.0000 - "operation not supported on external-organized table".
  * Cause: User attempted on the operation on an external table which is
  not supported.
  * Action: Don't do that!
  
  **********************************
  
  I don't know what to do. I did my best, please help.

  What happens if I want to import large data set in the external table?

  Hmm, external table is just a definition on how you want to watch a file as a table in the database. Think of it as a tool to import data.

  1. first of all, have a ready file (with data).

  2. create an external table using the format of the file.

  3. now you should be able to see the data when you do this. Select * from my_external_table.

  4. now, create an ordinary table where you want the data to insert permanently.

  5 insert into permanent_table select * from my_external_table.

  I hope this helps.

• How to select the values for each check box in a group of records

  Hello
  
  I have a requirement in form 10g. In this form there are 10 records are display each record has a checkbox is there if I click on the check box save number one and number three and make some changes in the text field (field adjustment is the number data type) and then finally, I want to see the total a total amount called field.
  
  In this, my question is how to select specific to a group of records records? and finally these selected records are inserted in a table.
  Because I am not able to read these records at a time.
  Is there any table to define a record group to fetch each of them individually for example Rec [1] Rec [2]... like this if yes please suggest me the steps how to do this.
  
  Thanks in advance

  OK, so you want to shoe the total amount in the form itself (I guess that somewhere under the dashboard lines?).

  You can do this easily using formulat elements:

  1 create a new item in your block where the field amount is places, set "section of the database" on the 'No', 'calculation mode' to the 'formula' and the 'formula' himself to something like:

  CASE WHEN :BLOCK.CHECKBOXITEM=CHECKVALUE THEN :BLOCK.AMOUNT+:BLOCK.ADJUSTMENT ELSE 0 END;
  

  This formula returns 0 if the checkboxitem is not checked, otherwise the sum of amount and adjustment (of course you can adjust the names of elements and the value for 'Checked')
  2. place the element in the layout, if you wish.
  3. set the property "Query all Records" to "true" for your block elements, this is necessary for the calculation to work
  3 create a control block to keep summary article in a, "Single Document" set to 'True '.
  4. place a new element in this control block, set 'Calcuation mode' to 'Summary', 'Summary block' to your block elements, 'Summary point' in newly created formula section in the block elements
  and function of synthesis for the "sum".
  5. place the element in the layout

  She's.
