  EXISTS checks for the existence of an element, not a value. Since you're using VARRAY (btw, it is not recommended), your only choice is a loop through:

  SQL> DECLARE
    2       TYPE dnames_var IS VARRAY(7) OF VARCHAR2(30);
    3       dept_names dnames_var := dnames_var('Shipping','Sales','Finance','Payroll');
    4  BEGIN
    5      for i in 1..dept_names.count loop
    6        if dept_names(i) = 'Shipping'
    7          then
    8            dbms_output.put_line('Exists ................');
    9            exit;
   10        end if;
   11      end loop;
   12  END;
   13  /
  Exists ................

  If you use the nested table, you can use MEMBER, SUMBULTISET, MULTISET EXCEPT:

    3       dept_names dnames_var := dnames_var('Shipping','Sales','Finance','Payroll');

• How to make the metadata field existing in the form page to customize

  Hi all

  I want to add some fields in my form. I managed to create the new field, and then make a settlement and put it in the profiles of school boards. My form has display fields, I just created. My questions are:

  1. how I want to add the existing field such as title, author and security group (the box highlighted in red according to the attachment) in my form?

  2. I noticed that when I create the new field, it will be added in standard integration page. There are fields to check standard on the page become more. How can ensure me that the fields that I created was not display in standard integration?

  I noticed the global and non-global rules but not enough on this clear. Could someone help me or provide some steps for me with regard to my two questions?

  Here, I have attached my form page and standard check in the page that I want to put in my form page.

  

  

  Thank you.

  If you ask about control in the profile of Content Server native interface user then: -.

  If you want to add the title, author, group security (system default metadata) as well as your metadata created in your check-in form.

  then add these fields in your rule. The rule is the same that you have created for your profile (ARA).

  For your second question: -.

  Whatever profiles, all metadata added in the content server, are displayed in the Standard profile balance.

  You can hide the standard profile, if it's not necessary.

• How to check if a table exists in the database or not?

  People,

  Hello. I use the server of Oracle 11 GR 1 material with Oracle Linux 5 database.

  My instance of database is named HRCS90, which the user access Id is MyName, and his identification of user SYS system.

  I have a few questions about user ID to access the PSRECDEL and PSROLEDEFN table in the HRCS90 database as below:

  SQL > select * from PSRECDEL;

  His output under the SYS user: table or view does not exist.

  His output under user myName: no selected lines. This means that the table THAT PSRECDEL exists, and myName user can access.

  SQL > select * from PSROLEDEFN;

  His output under SYS and MyName: table or view does not exist.

  My questions are:

  How to check if a table really exists in the instance of database HRCS90 or not?

  Thanks in advance.

  
  

  If a table is present in the database, it must be present in DBA_OBJECTS. If he fell, he would be present in the TRASH. If he fell purged, it is not available in the database, Cant it confirm you this object is not in the database? See a little test here

  SQL > CREATE TABLE TESTTAB (ID);

  Table created.

  SQL >

  SQL > SELECT MASTER, OBJECT_NAME FROM DBA_OBJECTS WHERE OBJECT_NAME = 'TESTTAB.

  OBJECT_NAME OWNER

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

  SCOTT TESTTAB

  SQL >

  -Drop table (without purging. So now, it will be in the recyclebin)

  SQL > DROP TABLE TESTTAB;

  Deleted table.

  SQL >

  SQL > SELECT * FROM DBA_RECYCLEBIN WHERE ORIGINAL_NAME = "TESTTAB;

  OBJECT_NAME ORIGINAL_NAME OWNER

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

  SCOTT BIN$ 8LKloIv3SYWA0WJ33GS + Aw == $0 TESTTAB

  Now see this case when you use PURGE. If it won't move the table to the trash. First of all I am clear the existing dba_recyclebin to the user entries. Then I'm falling table using purge.

  SQL > PURGE TABLESPACE USERS USER SCOTT.

  Purged tablespace.

  SQL >

  SQL > SELECT * FROM DBA_RECYCLEBIN WHERE ORIGINAL_NAME = "TESTTAB;

  no selected line

  SQL > CREATE TABLE TESTTAB (ID);

  Table created.

  SQL >

  SQL > SELECT MASTER, OBJECT_NAME FROM DBA_OBJECTS WHERE OBJECT_NAME = 'TESTTAB;

  OBJECT_NAME OWNER

  ------   ----------

  SYS TESTTAB

  SQL > DROP TABLE TESTTAB PURGE;

  Deleted table.

  SQL > SELECT * FROM DBA_RECYCLEBIN WHERE ORIGINAL_NAME = "TESTTAB;

  no selected line

  SQL > SELECT MASTER, OBJECT_NAME FROM DBA_OBJECTS WHERE OBJECT_NAME = 'TESTTAB;

  no selected line

  Since there is no entry to both DBA_OBJECTS and DBA_RECYCLEBIN. So that means that the particular object is not in the database.

• How to check if the field is always get incremented by 1

  Hello all-

  This might be a very basic question. I'm just checking if a field is get incremented by 1 only. Here's my table structure:

  CREATE TABLE 'DIM_STAR_DAY '.

  (

  NUMBER of "DAY_DW_ID."

  "DAY."

  NUMBER OF "DAY_NBR_IN_EPOCH."

  NUMBER OF "DAY_NBR_IN_EPOCH_LY."

  NUMBER OF "DAY_IN_WEEK."

  NUMBER OF "DAY_IN_PERIOD."

  NUMBER OF "DAY_IN_QUARTER."

  NUMBER OF "DAY_IN_YEAR."

  CONSTRAINT 'PKDIM_STAR_DAY' KEY PRIMARY ("DAY_DW_ID") WITH THE HELP OF INDEX PCTFREE, INITRANS 10 2 MAXTRANS 255 COMPUTE STATISTICS NOLOGGING STORAGE (INITIAL MINEXTENTS THEN 1048576 65536 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 USER_TABLES FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT) TABLESPACE "MART_INDX" ENABLE

  )

  I want to check the field DAY_DW_ID should it still increased by 1 which corresponds to DAY field which means this condition should never happen, because these are two continuous days and day_dw_id should increase by 1 only:

  • Day_DW_ID DAY
  • 5964-4/26 / 2014
  • 5981 4/27 / 2014

  How can I write a query that gives me all these days where corresponding day_dw_id is higher than its previous day_dw_id 1. Thanks for your help and your answers. Very much appreciated.

  Hello

  This sounds like a job for the analytic LAG function:

  WITH got_prev_day_dw_id AS

  (

  SELECT d. *- or else

  AS trolling (day_dw_id) prev_day_dw_id (ORDER BY date)

  OF dim_star_day d

  )

  SELECT *.

  OF got_prev_day_dw_id

  WHERE day_dw_id <> 1 + prev_day_dw_id - or >

  ;

  This will display the rows where day_dw_id is greater than 1 higher to day_dw_id on the previous line (where 'previous' means 'in the order of day").  It also displays the rows where day_dw_id is less than 1 higher than the previous day_dw_id.  If you want to only include rows where the difference is greater than 1, then use > in the WHERE clause instead of <> .

  I hope that answers your question.

  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.

  Explain, using specific examples, how you get these results from these data.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• How to check if a folder exists

  Hello
  
  I have a custom filter component:

  public class BarcodeMetadataFilter implements FilterImplementor{
  }

  I check here if the file exists in xCollectionId value, so I have two qustions:
  
  (1) should what service I call to check if the file exists?
  (2) how to call this service from the filter?
  
  Kuba

  Call a service such as COLLECTION_GET_INFO. Pass the parameter dCollectionID which must be xCollectionID. If you receive and error, it may mean that the folder does not exist. You should check the error (exception) to ensure what he wants to say to you is that the folder does not exist.

• How to check if the link exists in the remote site

  Hi all:
  
  Guys please can you me if there is a way I can check if the link exists in the remote site? for example
  
  < cfif hyper link to www.mysite.com exists in www.remotesite.com >
  good... We will continue
  < cfelse >
  Please add link to www.mysite.com before continuing
  < / cfif >
  
  Is this possible... you have to use the spider? If yes how?
  
  Thanks guys,.
  A
  

  to develop the excellent suggestion of tclaremont:

  You can use refindnocase() to search the returned by cfhttp filecontent
  call us at:

  http://www.yourwebsite.com">
  method http://www.VisitorsPage' = 'GET' result = 'Foobar '.
  ResolveUrl = "yes" getasbinary = "auto" >
  <>
  foobar. StatusCode is "200 OK" >
  ] * href [^ >] *' & replace (myurl, '. ',' \.',)
  'all') & '[^>]*>(.*?) <\>', Foobar.filecontent) >
  link
  
  no link...
  
  
  ... connection error or the web page you requested does not exist...
  

  of course, if the www.VisitorsPage site is sneaky and has the link to
  your site code page, but hide it with css/javascript, it's going to
  be difficult to discover using regexp... better just go and watch their
  Web site...

• How to check if a node exists in the XML file?

• How to check if a file exists?

  Hi guys.

  I am running javascript in Acrobat .pdf file created in LiveCycle Designer.

  I need to check in silence if an external file outside the open document (C:\something\something\something.pdf) exists or not.

  I understand that I'm only able to do this as a function of confidence within a script to the folder level javascript.  I am familiar with those.   The problem is, I don't know what function I should use and will have a difficult time in the research on it.

  Try to use: doc.exists?

  Try to open the document with a function and catch the error if the file does not exist?

  I'm not so sure that if I just spend my path as a string, say "/ C/Something/something/something.pdf" or if I should first deal with the file as an object like:

  var myFile = new File("/C/Something/something/something.pdf") (which was not in Acrobat... don't try to run it as a function of confidence)

  Please notify.

  Thank you!

  I finished this figure myself.

  XFA/JavaScript in my paper, I call a custom function that I have written and pass a string (or a string variable containing) my file path for that I would like to check:

  if(typeof(MJS_FileExists) == "function") {
      try {
          if(MJS_FileExists("/C/something/somethingelse/filetocheckfor.pdf") == true) {
              xfa.host.messageBox("file is there");
          } else {
              xfa.host.messageBox("file is NOT there");
          }
      }
      catch(e) {
          app.alert("Processing error: "+e)
      }
  }
  

  The function I call is a folder level javascript.   You have to maybe do some Googleing on how and where to install them.   In the my file .js file real javascript level where the function is housed I use:

  var MJS_FileExists = app.trustedFunction(function(filename) {
      app.beginPriv();
      var existingDoc = false;
      try {
           var checkDoc = app.openDoc(filename);
           checkDoc.closeDoc();
       existingDoc = true;
      } catch(e) {
       existingDoc = false;
      }
      return existingDoc;
      app.endPriv();
  });
  

  It took me a lot of trial and error.  It sucks there is not a lot of in on the internet on how to do it via Acrobat / Live Cycle.   Hope this helps someone else.

  Tom

  You mean from the host? You can use the FTP functions. "FTP Get path Info.vi" returns error code 550 if a file is not but a code of success if he finds. You can also check the output of "path info". The type will tell you unknown if there isn't but the file if it is there.

• How to check a field whose type "list check box"

  Hello

  How can you check if a field with the field type "list box" is checked or unchecked in a web - app.

  If I use

  {% If the element.} ['Open everyday of the week']! = « » -%}

  {{point. ["Days of open doors week"] | {{replace: ',', ' '}}

  {endif %}

  It shows all the values checked in the chain.

  If I use == "" == "0" (to check if the string is empty), it does not show anything. "

  I want to trigger the checkboxes 'disabled '. The question is: how?

  Thanks for any help.

  Kind regards

  Carla

  It is events Dynamics Carla. BC didn't spit on a value checked or unchecked in this regard.

  If it's to do with the front-end server and users by clicking on this javascript.

  In terms of BC, it spits out data, NOT html. This output is not html, so you must use the value to train your HTML code. IF it is a value, then you can checked in your entrance to box OR not if it's the other value.
