• Question about mySQL Date and NULL value

  I am using phpMyAdmin for a simple mySQL database. Am a little confused here, as I have two date fields that, as far as I can tell, are the same - ticked i.e. Date, with a default of null with the NULL value.

  If I update a record, but let both of these fields is empty, it remains empty, and the other is filled with the 0000-00-00 (and displays 30 November - 0001 Web site.)

  Pointers on why two supposedly identical fields are different?

  Thank you.

  It must be in the script.

  Is it possible to copy and paste the script here. The script that causes the problem is the script Insert or Update script. A list of the fields in the table will be also useful.

• oci_bind_by_name and null values

  Hi, I'm developing a PHP application that allows users to execute SQL statements on an Oracle database. The idea behind the app does the administrator pass a query with some bind variables, for example:
  
  SELECT NAME, SALARY, DEPTNO of EMPLOYEES WHERE SALARY >: salary AND DEPTNO =: deptno
  
  After this, users are presented with a series of screens that allow them to select columns that they want to see (in our case they could choose between NAME, SALARY and/or DEPTNO) and enter values for the bind variables (in our case it would be salary and deptno). So far, everything works as expected.
  
  The problem I have is that if a value null is entered (say for example in deptno, we know the employees that are part of any Ministry), the oci_bind_by_name() function function that I use php to make the bindings of variables does not match all records. I understand that if you put something like "AND DEPTNO = NULL" the query should return no results. But, is it possible to do with oci_bind_by_name() behave similarly as if the query would have been "AND DEPTNO IS NULL" when it receives a null value?
  
  Modify the query using PHP is an option that I would avoid because I can't make all the assumptions on the query as it is entered by an administrator.
  
  Thank you for your time.

  Because this behavior is not specific to PHP OCI8 or the use of bind variables, you'll need to arrive at a SQL solution.

  Your comment about not being able to make assumptions on the motion seem strange: If the administrator wants the semantics you describe, they will need to write the SQL statement that is appropriate for their desired output.

  Other types of solutions include put (s) in a PL/SQL procedure that returns a ref cursor You can hide the complexity of PHP by linking only to the PL/SQL procedure parameters. But this seems to deviate away from your goals.

• select_list_from_lov_xl and null values

  I'm creating a column on a report that will have a lov by using the code below: -.
  
  apex_item.select_list_from_lov_xl (p_idx,
  p_value,
  "ARL LOV."
  l_attributes,
  '' YES. ''
  "% null %."
  "Please select."
  NVL (p_item_id, item_id (p_idx, p_rownum)));
  
  The problem I have is that exisiting records where the value of the column (i.e. the lov for) is null, it is not translating null values in the text "Please select. The text is displayed in the lov when you click on the list, but it should appear as a default value, as for page elements that use the same lov.
  
  We saw what happens and you know how I can get around it?
  
  Andy.

  Try using the NULL value instead of null %. See this example:

  http://Apex.Oracle.com/pls/OTN/f?p=31517:209

  Add lines to the form of tables and see the selection list.

• APEX 3.2 copying the model Vertical Type 2 (including null values)

  I have normally do not change only by default APEX models, but rather to make a copy and edit my version with what I want to do.
  
  In the reports to a SQL report attributes TAB, I start using the "default report: vertical, look2 (include the Null columns)" for my report. I went to shared components, make a copy of the model that has been referenced in my application. (Took me by surprise, but he appeared in lists) When I go to replace the expression with the new COPY of the template, it is not in the LOV for models. I checked the copy worked and it is present if I show all THE MODELS...
  
  Why it displayed verses list reports?
  
  Can the attributes of reports / Tempalte LOV reports updated to include my new model?
  
  Thanks - Jim

  I start by using the "default report: vertical, look2 (include the Null columns).

  default: report models are hardwired into APEX and cannot be changed the way the theme templates can.

  >

  Models 'appear' under lists will list templates, not report models. Any similarity of name to a default: model report is a coincident.

  Can the attributes of reports / Tempalte LOV reports updated to include my new model?

  It will show only integrated default: / export: templates and report from the current theme templates.

  Using the web Inspector in a browser with the tools of development such as Safari or Firefox + Firebug you can look at the source of the report with a default: model to determine the HTML structure and classes used and applied by the APEX CSS selectors, so either replace these in a your own style sheet, or create a custom theme version of the model from scratch.

• Displaying a string instead of the "null" value in the columns of answers

  Hi, is it possible to display a string (e.g. "no data") in responses instead a NULL value in a column of a table or a PivotTable? I read everything by using the formula in the column section in the answers, but I do not understand what expression should be used... could you help me?
  
  Is this kind of possible substitution only in the web interface of answers, or still in BI Admin meta - data? I would be very interested to recognize from analysis UDML in metadata,
  Thanks in advance!

  You must do this in the business model and the Mapping layer

  Go to the properties of the column

  1. in general tab, you have "use existing columns of logic as a source.
  Select this check box. Click the period (...)
  In the formula for the column, you can add the condition of ifnull
  In this col formula editor, you can choose the logical columns.

  2. on the Data Type tab, you have the maps and logical sources
  Here too you can achieve.
  In this col formula editor, you can choose physical columns.

• Separate s processed NULL values in indexes

  http://docs.Oracle.com/CD/B19306_01/server.102/b14220/schema.htm#i20690

  Indices and null values

  NULLthe index values are considered as distinct except when all non - NULL in two or several lines of an index, the values are the same, in which case the lines are regarded as the same. Therefore, UNIQUE i index prevents the lines containing NULL values to be treated as identical. This does not apply if there is not a no - NULL values - in other words, if the lines are fully NULL .

  The bold part: who's trying to tell me that the lines for the NULL indexed lines, that if these indexed 2 NULL values maintain the same values for the rest of the line that oracle treats as unique to them?

  That being said, the bold part is qualified with this statement:

  Therefore, UNIQUE i index prevents the lines containing NULL values to be treated as the same.

  
  

  
  

  
  

  In fact all this 2 average values in a single column being zero, with the rest of the line being exactly the same, is not treated as identical.

  
  

  I'm sure that's what the DOC tries to explain.
  

  Consider that you have a composit index SINGLE a two columns COL1 and COL2. And you want to insert some values like this

  ROWNUM COL1, COL2
  ------- -------- --------
  1 1 NULL
  2 2 NULL
  3 3 NULL
  4 3 NULL

  NULL values in the index are considered to be separate

  This statement indicates that NULL in COL2 values are considered to be UNIQUE values. If the NULL in COL2 ROWNUM 1, 2 are considered to be two different values.

  But the following statement

  except in the case of all values not NULL in two or more rows of an index are the same, in this case, the lines are considered to be identical

  This statement says ROWNUM 3, 4 for COL1, where they have identical values, where the NULL in COL2 value are not considered as UNIQUE values but as identical. That's why the 4 ROWNUM insert will fail with UNIQUE constraint violation.

  PROFILE of column

  I havets is of type VARCHAR2. I know that again I can partition as Oracle convert internally to varchar2 in number when the data is inserted. But the INTERVAL is not possible.  However, so could you please suggest how RANGE partition on PROFILE?

  CREATED_ON column:

  It's the NUMBER with decimals. Could you guide me please?

  Please let me know if you need more information?

• ADF BC - difference between the number and the Types of attributes DBSequence

  Hi all
  
  The ADF tutorials and examples, when you define an entity object, I understand that we could make use of the type of the DBSequence attribute and a trigger of DB to set a unique ID column on a table in the INSERT.
  For the same primary key attribute, I tried to use the Number data type. Now, with the DB of active trigger, I was able to achieve the same result as before. Additional configurations, I had to make sure that when using the data type numbers will allow "Refresh after insert", define Updatable when new and define a default value (I put this as - 1).
  
  My question is what is the difference between using a number and DBSequence of the types of data for a field? Is that just a data type DBSequence avoids the manual installation of the above properties?
  
  Thank you

  Hello

  With your approach, you tried to create several lines and then engaging them? Seems that your solution works for as long as there is only one line, you create both

• Bad high and low value with the varchar2 data type

  Hello
  
  It is an application on e - biz on database 9205, with inventory module.
  
  In one of the mtl_txn_request_headers of the table, the data for the number of application type is varchar2 (30). When I checked the low_value & high_value in dab_tab_columns, I see that the low_value is 100001 (6 digits) and high_value is 99999 (5 digits).
  
  I used the utl_raw.cast_to_varchar2 (low_value) to convert the value.
  
  In our case, we save a large part of the value in incremental number and some of our query will be in the predicate of the range (between).
  
  How should I handle this kind of situation and which option do I?
  
  Appreciate any help. Thank you.

  Accepted this looks like a classic bad-data type problem, but as this picture seems be part of Oracle E-Business Suite the OP should probably talk first Oracle.

• How to return a NULL value in LOV and insert into a field of allowingNULL number 4?

  Hello
  
  I have the following LOV and the return_value is PeopleId which is number 4, allowing NULL. And the LOV options are as follows:
  
  LOV named--> select named LOV-
  Show Extra values-> no
  Dynamic translation-> - untranslated-
  The number of columns - > 1
  Display Null-> Yes
  Null-> - Select value-
  Return NULL,-> NULL value
  ^^^^^^^^^^^^^^^
  
  ----------------
  
  List of values definition:
  Select Lname | ', ' || Fname | ' ' || Mname as display_value, PeopleId as return_value
  of PEOPLETB
  where PEOPLETYPE ('i', 'HERE', 'IF')
  order by 1
  --------------
  
  Given that PoepleId is a number 4, allowing NULL. I want a NULL value will be inserted, if the user does not select anything in the drop-down list. It seems that I would get "ORA-01722: invalid number" error when the PeopleId msg is null (ie: user doesn't have a selection). What is the good 'return Null value' I need to put it in? I tried "NULL" (see above) or nothing, it still does not work.
  
  Any suggestions?
  
  Thank you very much
  Helen

  Hello Helen,.

  You have found one of the many sources of my frustration with APEX. Here's what I do:

  In the definition of the element in your page, go to the LOV part and implemented like this:

  Display Extra values: Yes a dynamic conversion (I ignore this)
  Number of columns: 1 display Null: No.
  Display null value: (leave blank) return Null value: (leave blank)

  An empty row is displayed when the user comes first to the screen. If they do NOT select the drop-down list, the value is left empty (null).

  If anyone has a better way, I will definitely experiment with it.
