• How to check the existence of a value in a table before copying the data?

  Experts,
  
  I have a requirement in which I need to copy data (4 columns) table A to table B (4 columns)
  
  Table A (entry)
  
  PART_ID PART_NAME PART_OPT_CD ENGG_OPT_CD
  
  1 "AAA" 10 100
  2 'BBB' 20 200
  3 'CCC' 30 300
  4 'DDD' 40 400
  5 'EEE' 50 500
  
  
  I have a table named OPTIONS with a single column. This is a table of reference of business which has the master list of option codes.
  
  OPT_CD
  10
  20
  30
  50
  60
  100
  200
  400
  500
  
  
  I need to copy Table A to Table B, but in doing so, I need to check the values of columns 3 and 4 in the OPTIONS array.
  If there is copy the folder B. Otherwise error in the log in a file/table and continue with the next copy
  
  TABLE B (exit)
  
  PART_ID PART_NAME PART_OPT_CD ENGG_OPT_CD
  
  1 "AAA" 10 100
  2 'BBB' 20 200
  5 'EEE' 50 500
  
  WARNING file or a table should have the details below.
  
  300 ENGG_OPT_CD does not exist in the table OPTIONS, so part_id 3 have not migrated
  40 PART_OPT_CD does not exist in the table OPTIONS, then part_id 4 have not migrated
  
  Company don't bother about the format of error, we need this information to correct the OPT_CD in the OPTIONS table.
  
  Can anyone suggest a better way to do this. Thank you for your help in advance

  Hello

  Its very similar to your previous post.
  Re: PL/SQL help
  The only difference being that you have to outer join to your superimposed master table, since your search in two columns values occur only in a single column on your Master table.

  Something like that;

  create table a (part_id number, part_name varchar2(10),part_opt_cd number,engg_opt_cd number);
  
  insert into a
  (select 1 Part_ID, 'AAA' Part_Name, 10 Part_Opt_CD, 100 ENGG_Opt_CD from dual union all
  select 2, 'BBB', 20, 200 from dual union all
  select 3, 'CCC', 30, 300 from dual union all
  select 4, 'DDD', 40, 400 from dual union all
  select 5, 'EEE', 50, 500 from dual union all
  select 6, 'FFF', 60, 500 from dual
  )
  /
  
  create table b (part_id number, part_name varchar2(10),part_opt_cd number,engg_opt_cd number);
  
  insert into b
  (select 1 Part_ID, 'AAA' Part_Name, 10 Part_Opt_CD, 100 ENGG_Opt_CD from dual union all
  select 2, 'BBB', 20, 200 from dual union all
  select 5, 'EEE', 50, 500 from dual
  )
  /
  
  Create table master (OPT_CD number);
  
  insert into master (
  select 10 opt_cd from dual union all

  You could do a count of the records before hand, but read on the PL/SQL manual could also help

• How to check if the variable (of type uint) has a value or not?

  Hi all

  I'm just trying to write an instruction conditional to check if my uint variable has a value or not.  I tried to check "null" and "undefined", but without any luck (see below)

  private var _tempIndex:uint;

  ...

  ...

  If (_tempIndex! = null) {}

  code here

  }

  had an error with that one, then tried

  If (_tempIndex! = undefined) {}

  code here

  }

  had an error with that as well.

  So, how can I check if a variable has been assigned a value or not? Any ideas? Thanks in advance!

  Mike

  A uint always has a value between 0 and 2 ^ 32-1 inclusive. It cannot store a value 'no' as undefined or null. If you declare a variable of type uint without assigning a value, it is given a default value of 0.

  You need to maintain an indicator Boolean separate or to use a type of data larger such as number (which can store NaN), object (which can store NaN or null), or * (which can store a value, including NaN, null, and undefined).

• How to check if the value of text is in a view accessor? How can I check for validation?

  Hi Experts ADF,

  JDeveloper 12.1.1.3.0

  I have a VO with a Segment1 column. And I have an accessor in my VO as SegmentVA which contains all the numbers.

  So in the user interface, I'm having a Segment1 as an inputText. The user should then enter values in inputText.  How can I check to validate that the value you enter must be valid within the ViewAccessor.

  Thank you

  Animesh

  You can use a declarative approach and define the Validation rule on EO attribute.

  Or you can create the method in your ViewObjectImpl class, expose this method as a customer interface, create custom for your input field validator and invoke the VO method from there.

• How to check the page dirty with default values existing in viewObject?

  Hi all

  I use JDeveloper 11.1.1.4.

  I have two pages in my application. I am browsing for page2 page1.

  Before opening page 2 I created new line page 2 notice of object using method 'Create Insert()' with some default values by using the ViewRowImpl class.

  My problem is that I have a button to return to Page 2. If I click the back button, then check the Application module is dirty or not.

  But it always shows AM is dirty due to I'm setting some default values in ViewRowImpl. If I avoid the default values in ViewRowImpl then AM dirty check works fine.

  My Question is how to check the AM (or) dirty Page with default values in the object view?

  My bean Codes:

  Links DCBindingContainer = (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

  DataControl dc = bindings.findDataControl("AppModuleDataControl");

  ApplicationModuleImpl am = ((ApplicationModuleImpl) dc.getDataProvider ());

  If (am.getDBTransaction (.isDirty (()))

  {

  return "Page is dirty."

  }

  My Jspx Codes:

  < af:commandLink id = "cl6" text = '2 '.
  shortDesc = "Add Row in Page2"
  actionListener = "#{bindings." Action CreateInsert.execute}' = 'Edit' >

  Thank you

I heard that "automatic cursor sharing" is enabled by default in GR 11, 2. But how to check, if a sql stealthily to its dregs id? Can someone share the query if you have?

  And also, all the links in this regard suggest me pls.

• How to check that the variable 'does not contain' value?

  Hello

  I use CP 7.0.1.237.

  We want to use the widget text box for a custom quiz and verify a response. While we understood how to check the existence of certain key words, we are not able to find a way to check that the content does NOT contain certain keywords. For example, we want to ensure that the text entered in this widget does not contain a "Transformation" and "Non-compliant.

  Is this possible at all?

  Thank you

  Anthony

  Anthony, it works perfectly. Created this conditional action with 4 decisions. I used the interaction of training text scrolling in CP8 (because now you can control the variable - which means I might have a Reset button):

  First decision:

  

  Second decision (the third is similar to the following)

  

  Fourth and final decision

  

  I put the variable words (v_first... v_fifth), it's a reflex I use since I shared actions that much. The variable associated to the ETB (you can now reset an empty var in CP8) is v_TextArea and the Boolean value that will decide if positive feedback (StarOK) should be shown is v_TA_OK. If you want to display a negative feedback, put this in the ELSE part of the final decision.

  FYI: it took 15 minutes, including the creation of assets and the variables and tests. Personally I would have needed more time to do it in JS, but that's just me.
