• How only include a WHERE clause only when a connection variable has a value?

  I use JDeveloper 11 g using business components of the tables. I'm now modify the auto-generated SQL code to include WHERE clauses which depend on the values of bind variables. For example I have something like this:

  SELECT mytable.firstColumn
  FROM myTable 
  WHERE myTable.secondColumn= :VariableValue

  However, this means that when VariableValue is null SQL would fail and I get an error. Is there a way I can include the WHERE clause (or clause AND according to the position in SQL) only when a bound variable has a value (or a particular value)?

  Or use: WHERE NVL(:VariableValue,myTable.secondColumn) = myTable.secondColumn

  Hello world.

  If you use view criteria to make your filtering and scoring mode 'filter' of the Victoria Cross to be "Both" (database and in-memory), then the framework will automatically use your filter to filter the lines again without having to write code or use your own rowMatch object.

• Plugin Automation: how to select a spot channel when 2 channels have the same name?

  I have a CMYK document open in photoshop. In the "LAYERS" Panel, I just added 2 tones with the same name "color 1" Sport.

  I click on the spot channel to select, the "Listener" plugin will be released a few c ++ code like below:

  
  SPErr PlayeventSelect(/*your parameters go here*/void)
  {
  Result PIActionDescriptor = NULL;
  DescriptorTypeID runtimeKeyID;
  DescriptorTypeID runtimeTypeID;
  DescriptorTypeID runtimeObjID;
  DescriptorTypeID runtimeEnumID;
  DescriptorTypeID runtimeClassID;
  DescriptorTypeID runtimePropID;
  DescriptorTypeID runtimeUnitID;
  SPErr error = kSPNoError;
  Move it to the top of the routine!
  PIActionDescriptor desc0000000000003980 = NULL;

  error = sPSActionDescriptor-> Make (& desc0000000000003980);
  If (error) goto returnError;

  Move it to the top of the routine!
  PIActionReference ref0000000000001A48 = NULL;
  error = sPSActionReference-> Make (& ref0000000000001A48);
  If (error) goto returnError;

  error = sPSActionReference-> PutName (ref0000000000001A48, classChannel, "1 Spot color");
  If (error) goto returnError;

  error = sPSActionDescriptor-> PutReference (desc0000000000003980, keyNull, ref0000000000001A48);

  If (error) goto returnError;

  returnError:
  If (result! = NULL) sPSActionDescriptor-> Free (result);
  If (desc0000000000003980! = NULL) sPSActionDescriptor-> Free (desc0000000000003980).
  If (ref0000000000001A48! = NULL) sPSActionReference-> Free (ref0000000000001A48).
  error return;
  }

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

  You can see "PutName" adds the name of the channel 'Spot color 1' to make reference to and I think it will not work properly if I add such a code for my project as the PS can not differentiate the 2 channels than by their name. Can someone tell me if there is another method of selecting channel spot? Thanks in advance.

  Hello

  Here's something tht docs, you may find useful.

  Index of Tryusing instead of name:

  SPAPI OSErr (*)	( PutIndex ) (RefPIActionReference , DescriptorClassIDdesiredClass, uint32 value)
  	Puts an index into a reference ( formIndex ) as well as the class desired for reference.

  Unfortunately I do not have C++ here to try I used just definition of documentation.

  Hope this helps.

• How to create a procedure for REF CURSOR output with any WHERE clause?

  I have a requirement like this: I have a huge question that need to reuse in my code over 10 times. This SQL has about 50 lines. Here for these 10 odd times sometimes changes in WHERE clause (columns are the same). So I can't create a view as SQL is not static.
  
  I thought to write a procedure with a para of WHERE_CLAUSE entry. I pulled out a refcursor sys by adding where clause. But I can't do it because you cannot add a clause like this where clause.
  
  i.e.

  PROCEDURE dynamyic_query (p_where_clause IN VARCHAR2, p_out_query OUT SYS_REFCURSOR ) IS
  BEGIN
  
    OPEN p_out_query FOR SELECT ......... FROM table WHERE || ' ' || p_where_clause;
  
  END;

  The foregoing gives an error.
  
  How to handle such a situation? Any help would be greatly appreciated.

  Looks like you can only set column_name =: z, column_name =: values of type y. You can not it seems to replace it with no WHERE CLAUSE?

  A bind variable, such as: it, represents a single value.
  If: is the VARCHAR2 '1 = 1', then

  SELECT tname FROM tab_test WHERE tname LIKE '%ABS_V4%' AND :y
  

  takes the value

  SELECT tname FROM tab_test WHERE tname LIKE '%ABS_V4%' AND '1 = 1'
  

  I think you want something like this:

  CREATE OR REPLACE PROCEDURE FORMS_TEXT_DYN_SQL_TEST
  (     p_where_clause      IN      VARCHAR2
  ,      p_out_cursor      OUT      SYS_REFCURSOR
  ) IS
    v_stmt VARCHAR2(1000);
  BEGIN
    v_stmt := 'SELECT ename FROM scott.emp WHERE ename LIKE ''%A%'' AND '
            || p_where_clause;
  
    OPEN p_out_cursor FOR v_stmt;
  
  END;

  show errors

• Case statement in a WHERE clause

  Gurus,
  
  Im trying to avoid Union of several select statements using a CASE inside a WHERE clause. When the parameter is defined as "What's new" it is advisable to use a code and for "Update Items" another condition.
  
  Having a problem with the following... I know that BOX in WHEREs instructions are allowed only can not make it work for this one.
  
  

  and case  when 'New Items' = 'xxx' --p_item_status 
           then  msi.creation_date = msi.last_update_date
        when 'Updated Items' = 'bbb' --p_item_status  
           then  msi.creation_date != msi.last_update_date
        else 1=1
  end;  

  Points for correct and helpful answers!

  Hello

  The great thing about CASE expressions, is that they allow you to use a login IF-THEN-ELSE in the clause SELECT, the ORDER BY clause or anywhere else. The WHERE clause has its own way to IF-THEN-ELSE logic, so even if you can use a CASE expression in a clause WHERRE, it usually does not help anything. You can do somehting like this:

  WHERE     (     :p_item_status        = 'New Items'
       AND     msi.creation_date  = msi.last_update_date
       )
  OR     (     :p_item_status        = 'Updated Items'
       AND     msi.creation_date  != msi.last_update_date
       )
  OR     (     :p_item_status        NOT IN ( 'New Items'
                             , 'Updated Items'
                             )
       )
  

  This guess: p_item_status is not NULL.
  If: p_item_status can be NULL, and you want to include all the lines where it is, and then change the last condition to

  OR     ( NVL (:p_item_status, 'OK') NOT IN ( 'New Items'
                               , 'Updated Items'
                               )
       )
  

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and INSERT, only relevant columns instructions), some values of the parameter and the expected results of these data for each value of the parameter.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• My watch connects the cloud. How to solve the problem

  I associated with my new iPhone 6 s more the iWatch after reset. He was previously associated with my iPhone 5s and worked perfectly. The software on all phones are up-to-date and Bluetooth is on. My problem is that the watch disconnects from the phone if the phone is not connected to the wi - fi in the House. It will automatically reconnect when I go in the House. How to solve this? It shows that it is connected to the cloud when I go in the House. I don't know how it happened. Even when I désapparier it from the phone, that he still continues to show as connected to the cloud. How to solve this.

  HI - it can help try the following steps:

  On your watch, go to: homescreen (via a simple press on the digital Crown) > (cog icon) settings > general > reset > erase content and settings.

  Then match your watch in your iPhone again, choose either backup restore (if the option is available) or set up as a new watch.

  Before doing so, it may be useful to close open applications on your iPhone (double-click the Home button and then drag upward on each app preview) and also to restart your iPhone.

  - Set up your Apple Watch - Apple Support

  For best performance, keep the Bluetooth and Wi - Fi enabled at all times on your iPhone (settings > Bluetooth settings > Wi - Fi).

  If you have a different user account with administrative privileges, Panel you can connect that account and change the password of your account of origin of the user accounts applet in Control Panel. If you do not have another account like this set upwards or that you do not have the password which you will need to log on to the built-in Administrator account. In XP Home, start the computer in Mode safe. This, by repeatedly pressing the F8 key as the computer starts. This will put you in the right menu. Navigate using your arrow up; the mouse does not work here. Once in safe mode, you will see the normally hidden administrator account. The default password is white.

  In XP Pro, you don't need to go to Safe Mode. In the home screen, do Ctrl-Alt-Del twice to get the classic Windows logon box. Type in "Administrator" and the password that you assigned when you set up Windows.

• a slightly different similar query where clause

  Hi all, I am facing a problem with my request.
  I have a query that looks like this
  
  with names like
  (select name, lastname, id
  FROM table1
  where id = 1
  and type = "enu".
  and asset = 'other '.
  and cashid = 2
  and $vdate = system_date
  )
  Select * from names
  (< joins with other tables)
  
  the thing is that enu value is past as parameter of the procedure. This is only of value if away from the front end.
  further, I have to spend 2 different values now ("cae", "peq")
  However, for these two values, of what I need not use the active column in where clause and the cashid will have to be change to cashid in (3.4)
  
  I was thinking a dynamic query construction and function of the value pass, I'll build the query. I am looking for another way to implement these changes with minimal impact on the code. Anyone know how to go around this case?
  
  with these two new values for the query are very similar with the exception of the active column that is more use and cashid will include an IN clause. only a value will be in the procedure, either enu, cae, peq. for enu, the query must be as above, but for the other two active column values are not in the query and cashid must be cashid in (3.4). How to take care of these scenarios

  with names as
  (select name, lastname, id
     from table1
    where id = 1
      and (
      (type = 'enu' and asset = 'others' and cashid =2)
      or
      (type in ('cae','peq') and cashid in (3,4))
      )
      and vdate = system_date
  )
  select * from names
