• Simple find() return is not the expected results

  I'm new to ColdFusion, but have been programming for a while now.  I have (what seems) an easy problem that I thought would be a simple solution, but I'm currently stuck.  Any guidance would be appreciated!

  I have the following code:

  < cfset brand = Trim (products. BRAND name) / >
  < cfif Find (brand name, ",") >
  < cfset brand = ""' & brand & ' "" / >

  < / cfif >

  My goal is to surround the text with 'if the string contains a comma.  I tried the standard comma, as Chr (44), but neither returned the expected results.

  What I am doing wrong?  The CSV file, creating, is sprayed upward for the name of a company is like 'Test Company, Inc.'

  Please help us save my sanity!  TIA!

  I think the first thing we do is to read the docs.  And if you may have read 'em a little closer... ;-)

• ctxrule - match does not return a result

  v.11.1.07 - I created a ctxrule index as described below. However, although a query must match on the given document, it does not return. Any ideas?
  

  begin
  ctx_ddl.create_preference('ot_lexer', 'basic_lexer');
  ctx_ddl.set_attribute('ot_lexer', 'index_stems', 'ENGLOSH');
  end;
   
  begin
  ctx_ddl.create_section_group('ot_sec_group', 'auto_section_group');
  end;
   
  create table ot_profile_test
  (profile_id number,
  query clob);
   
  create index ot_profile_rule_ndx on ot_profile_test(query)
  indextype is ctxsys.ctxrule parameters
  ('stoplist ctxsys.empty_stoplist
  section group ot_sec_group
  lexer ot_lexer');
   
  insert into ot_profile_test values(1, '($apple and $pear) and (1 within food)');
  commit;
   
  exec ctxsys.ctx_adm.set_parameter('log_directory', '/yourdir');
  exec ctx_output.start_log('ot');
  exec ctx_output.add_event(ctx_output.event_index_print_rowid);
  exec ctx_output.add_event(ctx_output.event_index_print_token);
  exec ctx_ddl.sync_index('ot_profile_rule_ndx', '2040M', null, 1, null, ctx_ddl.lock_nowait_error);
  exec ctx_output.end_log;

  Then, run a query:
  

  declare
  a clob := 'apple orange pears banana
  <metadata>
   <indicators>
     <food>1</food>
   </indicators>
  </metadata>
  ';
  vn_profile_id number;
   
  begin
   
  select profile_id into vn_profile_id
  from ot_profile_test
  where matches(query, a) > 0;
   
  dbms_output.put_line(vn_profile_id);
   
  end;
   
  ERROR at line 1:
  ORA-01403: no data found
  ORA-06512: at line 8

  Profile_id = 1 should not be returned?
  
  
  In addition, the log file should not have 2 lines written in $I?
  WRITING APPLE: ((PEAR) TOKEN = (PEARS)) * ((1) IN FOOD), 0
  WRITING APPLES: ((PEAR) TOKEN = (PEARS)) * ((1) IN FOOD), 0

  As noted earlier, you must use a list of words, not a lexer to control, like the two conflicts between them. All what you need to do is remove the following line from your code:

  ctx_ddl.set_attribute ('ot_lexer', 'index_stems', 'ENGLISH');

  You can still have a lexer with other attributes; Just do not set the attribute index_stems to the lexer. Set the attribute generator of forms derived from the list of words only.

• Strange case. =' and 'AND' do not return a result expected

  Hello

  I need to select rows in a table, excluding rows with col2 = 'o' AND 'EA' in the column BOXCODE.

  Lines with col2 = "O" where BOXCODE is equal to any other value except "EA" must be included in the result.

  I created a test table, inserted a few lines:

  create the test56 table (col1 varchar2 (1), col2 varchar2 (1), boxcode varchar2 (2))

  insert into test56 values ('1', 'o', 'EA')

  insert into test56 values ('2', 'o', 'BB')

  insert into test56 values ('3 ', ' 1', 'EA')

  I need to return these rows:

  ('2', ' O ', « BB »)

  ('3 ', ' 1', 'EA')

  Here is my SQL:

  Select * from test56

  where col2! = "O" AND BOXCODE! = "EA."

  /

  No row is returned:

  COL1 COL2 BOXCODE

  -------  -------  ----------

  0 response (s) selected

  Why? Oh why? No explanation?

  Thanks for your comments

  I need to select rows in a table, excluding rows with col2 = 'o' AND 'EA' in the column BOXCODE.

  Lines with col2 = "O" where BOXCODE is equal to any other value except "EA" must be included in the result.

  ALWAYS, ALWAYS, ALWAYS use parentheses when writing the conditions made.

  Did I mention that you should ALWAYS do that?

  You have written the requirement correctly. If you have added in brackets in your English needs you'd have this:

  excluding the ranks with (col2 = 'o' AND 'EA' in BOXCODE)

  And then rewrite that you would have the following code:

  to the exclusion of the ranks with ((col2 = 'O') AND BOXCODE = "EA"))

  Then the "outside" becomes the NOT operator

  NO ((col2 = 'O') AND BOXCODE = "EA"))

  "To the exclusion of the lines with" applies to ALL of these conditions so NOT a to apply to EACH of them. So just put ALL brackets.

  where col2! = "O" AND BOXCODE! = "EA."

  That! Applies ONLY to the FIRST condition

• REGEXP_LIKE return is not the expected results

  My first attempt at REGEXP_LIKE and I am obviously missing something. I tried several suggestions I found on the forum but can not get the correct results.

  y at - it something wrong with my request as it is only showing to the user who is logged in the drop-down list to the bottom of the list and not the accesslevel = 1 users too.

  Thank you very much

  Your application uses AND, which means that both conditions must be met: 1 user access level and specific ID. As a result, you will get a single result.

  If you want all the people with the 1 and the specific user access level (regardless of the level of access), to modify AND where.

• % ROWCOUNT SQL does not return the expected result

  I have the following function within a package:

  --Update APPERY_JTI_deleted_USERS table:
  FUNCTION fn_updt_app_jti_dlt_usr(
      p_update_co      IN VARCHAR2,
      p_appery_user_id IN APPERY_JTI_deleted_USERS.appery_user_id%TYPE,
      p_outlet_code    IN APPERY_JTI_deleted_USERS.outlet_code%TYPE)
    RETURN NUMBER

  EXCEPTION
  WHEN OTHERS THEN
    RETURN -1;  
  END fn_updt_app_jti_dlt_usr;
  
  

  The function called several times as part of a job. Basically, the main function (Say M), call a few functions (for example A1... A9). Each of these functions is to do something and updated the application using the above function. Therefore, each of the nine functions will call the above function with different parameters.

  The problem that I am facing is:

  First run, invoke only first of all for the above function will return the positive result ($sql rowcount > 0). When I run M the second time, only first and second calls for the above function will be to return positive results and so on.

  How odd, it's that if I change the values again and run a function M, it will start from the beginning. And what strange more, the dynamic update statement is executed correctly and data are updated successfully. It's just sql rowcount % do not return is not the expected results.

  I tried to run execute immediately without (begin, end). I also tried to run it without HELP ON. It's always the same. I'm really confused, what Miss me here.

  I don't know if this is relevant. But for what it's worth, invoking the function above updates the SAME lines in the table appery_jti_deleted_users that the columns are different. So for all the work, the same lines need to be updated. Each function (A1... A9) will call the above function to update a different column of these lines.

  If you REALLY want to help you having US SHOW, not tell us:

  1. WHAT you do

  2. HOW to

  3. WHAT results you get

  4. WHAT results you expect to get

  First run, invoke only first of all for the above function will return the positive result ($sql rowcount > 0). When I run M the second time, only first and second calls for the above function will be to return positive results and so on.

  How odd, it's that if I change the values again and run a function M, it will start from the beginning. And what strange more, the dynamic update statement is executed correctly and data are updated successfully. It's just sql rowcount % do not return is not the expected results.

  Perhaps that the foregoing is true and maybe he's not. We have NO WAY of knowing because you don't SHOW US anything.

  I tried to run execute immediately without (begin, end). I also tried to run it without HELP ON. It's always the same.

  Yet once you showed us NOTHING >

  You do NOT FOLLOW best practices when you use dynamic sql statements: the sql statement real so that you can print:

  1 SEE what's running - make sure there are no syntax errors, and it seems to be what you wanted

  2 EXECUTE/TEST manually - to see if he really runs without error and see what results it really give.

  3. FIX any syntax or other problems and retest it

  Instrument properly your code and you won't have the problems you are having.

  You should know by now what are the parameters are transmitted when you run the function. So, there are at least three sets of these parameters.

  So you should be able to:

  1 run the instrumented manually function three times

  2. see that all three SQL statements are

  3 manually run these instructions

  4. see that the number of lines is after each execution

  We have no idea of what the output of the function is every time you call it. Apparently, you have, if you save the results of the function somewhere, but you didn't post any of this info.

  We need real details to help you - just listen to your story is not enough.

• Invoke VMScript write-progress not released

  Hi all

  For the last few weeks, I'm building a deployment based on Excel-entry script.

  Basiclly to process goes like this;

  -you fill an excel file with all kinds of CPU, MEM, space drive, but also if you want to install IIS or SQL.

  -When you start the script, the system reads all this excel sheet cells and fills in the variable using PowerCLI.

  -PowerCLi then creates the computer virtual, based on your input.

  -Once the VM is created, there is only 1 file that will gets execution by invoke-vmscript.

  This line looks like.

  Invoke-VMScript - vm $VMName - ScriptText "Powershell.exe - ExecutionPolicy bypass - c:\PSScripts\StartConfiguration.ps1 of the file" GuestUser - administrator - GuestPassword *.

  It's a powershell script that will make a loop through a folder containing all sorts of PS-scripts. I do this so I have a modular deployment script.

  PS-scripts on the local computer virtual have writing and writing-exit courses, but I don't see them in my hand-console. The one where I started this...

  When I run the on my virtual machine itself, I see the progress bar and the out.

  How can I get what I see progress in my main screen to work?

  Moreover, I also tried running a file (with the progress-bar,...) with vmscript invoke, but does not

  Looks like my call vmscript;

  Invoke-VMScript - vm $VMName - ScriptText "Powershell.exe - ExecutionPolicy bypass - c:\PSScripts\001-WAN-LAN_networkconfig.ps1 of the file" GuestUser - administrator - GuestPassword *.

  Hope someone knows.

  Best regards

  Dave

  The Invoke-VMScript cmdlet uses the methods GuestOperationsManager to run a command on or copy files to/from the guest OS.

  For this, he uses the VMware Tools interface.

  In short, when you use Invoke-VMscript to run a PowerShell script inside a guest, what happens in the background is this:

  • Copy the script / command in OS invited
  • Run the script/command of the copied file
  • capture the result in a file
  • Copy the file with the output to the caller of Invoke-VMScript

  The Write-Progress output is in a stream that is not captured by the above process, so you do not get this output on the side of the appellant.

  On a sidenote, the Invoke-VMScript isn't a kind interactive session.

  If you want to see progress on the calling station, you will have to go to Remote PowerShell Sessions.

  It is indeed strange.

     cursor c_layer(p_xml xmltype) is
        select t.title, t.format, t.style
          from xmltable(
  

  or,

  (2) with the help of a FLWOR expression extended:

  for $d in //Layer
  where $d/TileMatrixSetLink/TileMatrixSet = "EPSG:28992"
  return $d
  

  You may have already noticed, but the problem only occurs in a context of PL/SQL.

• Validator do not return is not the results.

  Hi all

  I extended the StringValidator class in order to create a user name validator. When a new user is registered, the user name is validated on the server to check if it exists.

  The code is not thrown error and I know the remoteobject calls to work. The push sets the message, but the problem is that the result is not returned.

  The flow is correct?

  public class PosUsernameValidator extends StringValidator {
            
            private var userServiceRO:RemoteObject = new RemoteObject();
            private var validatorResults:Array = new Array();
            
            public function PosUsernameValidator(){
                 super();
                 userServiceRO.destination = "UserService";
                 userServiceRO.getUserByUserName.addEventListener("result", getUserByUserNameRH);
                 userServiceRO.getUserByUserName.addEventListener("fault", getUserByUserNameFH)
            }
            
            override protected function doValidation(value:Object):Array {
                 validatorResults = super.doValidation(value); 
                 return doForUserName(value);
            }
            
            private function doForUserName(value:Object):Array{
                 userServiceRO.getUserByUserName(String(value));
                 return validatorResults;
            }
            
            private function getUserByUserNameRH(r:ResultEvent, t:Object = null):void{
                 var user:User = r.result as User;
                 if(user!=null){
                      validatorResults.push(new ValidationResult(true, null, "Username error","Username already taken!"));
                 }
            }
            
            private function getUserByUserNameFH(f:FaultEvent, t:Object = null):void{
                 Alert.show(ObjectUtil.toString(f));
            }
            
       }
  

  Once the error message string from the server side, link it to property 'errorString' of any component of entry, you want to display the error on. This will give you the red border and a ScreenTip as if you used a validator. Don't forget to set the error return string to "" to clear the message once validation passes.

  My event.result may or may not return a node in the xml file. How can I avoid that TypeError: Error #1009: cannot access a property or method of a null object reference.

  I have a very simple question. I want to take the value of

  Event.Result.Item.nodeindex1.nodeindex2.Row.MyValue;

  and assign it to a text field

  mytextTi.text = event.result.item.nodeindex1.nodeindex2.row.myvalue;

  But if a part of the tree is missing, which is also valid, so I get TypeError: Error #1009: cannot access a property or method of a null object reference.

  I tried various solutions such as the following. Is there any simple way to do this?

  If (event.result.item.nodeindex1.nodeindex2.row.myvalue! = undefined)-does not work

  Unfortunately, one must test all levels to ensure that it is not null before the reference to it. You can take advantage of the short-circuit evaluation in tying together, for example

  if (event.result.item
      && event.result.item.nodeindex1
      && event.result.item.nodeindex1.nodeindex2
      && event.result.item.nodeindex1.nodeindex2.row
      && event.result.item.nodeindex1.nodeindex2.row.myvalue)
  {
      // access the variable
  }
  else
  {
      // one of the XML nodes in the path is null
  }
  

  Or you could stay away from her a little hacky and wrap the reference in a try/catch block.
