CFQUERY results return a null value for a varchar(MAX) field in SQL

I'm using ColdFusion 9 and SQL Server 2008.
One the fields in a table is defined as a varchar(MAX). Other fields in the table are ints, varchar(8000) varchar(256), etc.
When doing a query for records in the table and displaying the results using the cfdump tag, I see values in all fields in a row EXCEPT for the data in the varchar(MAX) field. The varchar(MAX) field shows a null value.  Yet, I can verify through the SQL interface or through Microsoft Access querying the database that the varchar(MAX) fields have data.
How can I retrieve data from this field type?
Thanks in advance for your help.

I'm wrong. I AM getting query results, but not what I expect. I had maxrows set as a variable in my original query, so when it returned 5 rows, the first row always showed as [empty string]. I've tried numerous queries now (where UID >100, where UID >200, where UID> 300, etc.) When I use <CFDUMP> to return the query, the first records always shows empty strings.
Here's an example of some records retrieved from this simple query:
<CFQUERY NAME="BuildBack" DATASOURCE="STORBASE">
SELECT *
FROM CallUnit
WHERE CCU_ID>172
</CFQUERY>
Any ideas?

  • Delete after trigger returns a NULL value for the old primary key??

    I am creat an After trigger that I was using to delete a row from another table. However, the OLD value returned for my primary key is a NULL value. I have an UPDATE and an INSERT portion to this same trigger that work fine with just grabbing NEW values, but this OLD value cannot be grabbed for some reason, although it seems to work on other tables when the owner is me, the problem table is not owned by me though. Has anyone run into this before? Is there a view that I need access to from this table or perhaps a setting I need to turn on? I am at a loss. Thanks.

    Cannot reproduce with this modified trigger code … right now I believe the problem is in this part:
    BEGIN
      col_ret := vpack.vOPCollectIO(tpid, User, 'SCOTT.OINFTABL', dmltype, vdata);
    EXCEPTION

    new akey=2
    new astring=cba

    vdata(3)=null
    vdata(4)=null
    1 row updated.
    flip@FLOP> delete from core.oinftabl where akey=2;
    old akey=2
    vdata(1)=2
    vdata(2)=null
    1 row deleted.
    So the trigger has the OLD AKEY value when DELETING and it does successfully store it in the VARRAY.
    Hence the problem is in that pl/sql block at the end.
    What are you doing in there?

  • DECODE to return a null value

    I would like to know how to return a Null value for a number based on users input.
    Somethingh like where A = DECODE(:input,'any',return is not null,:input)
    A is a number datatype.
    Thank you in advance
    -P

    Like if the input variable is 'any' then decode should return 'is not null' i.e. the query should return all the records where a particular column is not null.
    select * from EXAMPLE_TABLE where EXAMPLE_COLUMN =
    decode( :input, 'any', is not null, :input )
    Thanks for the quick response.

  • Validations: Null value for LOVs

    See http://htmldb.oracle.com/pls/otn/f?p=24317:239
    I have a "Item is not null" validation on that LOV item. The item has "Display null value" set to Yes and a LOV of STATIC2:1,2,3
    If I leave the Null return value for the item to blank, the engine defaults it to %null% and the validation "knows" that this is really the same as a null value and so it kicks in (good).
    But if I change the Null return value to something like %, the validation doesn't complain, it thinks that this is a not-null value.
    Why the inconsistency? Does this mean that we are expected to use the default value of the Null return value i.e. leave it blank and let the engine put in %null%?
    Comments? Thanks

    Vikas - The declarative not null validation types recognize "actual" null or %null% as null values. This equivalence holds in numerous other situtations during page processing. Why does %null% get special treatment? A convention was chosen and that's it. And it works for almost everybody in almost all situations. In other words, it's useful, if not perfect. If you want a different value, you can specify one in the LOV (as you described). Then you can recognize and convert these values to null or %null% in an after-submit computation so that validations and other mechanisms work normally. (Perhaps it would help if the Builder created such a computation for items having LOVs with specified null values.) One use case for using a specified null return value might be where you want to distinguish a POSTed "actual" null value from the selected "null" value for which you have specified a null return value. Then you can tell if the value was selected from the LOV or whether it got a null value from the item's cache or source methods.

  • FM returns wrong total value for Limit type PO's

    Hi all,
    I am working on SRM 5.0 (SP13) ECS.
    I have implemented the BADI "BBP_WFL_APPROVAL_BADI" for determining the Approvers for PO whenevr a PO is changed.If the diference between the Old PO value and new PO value is > 1000 and the approval text field(custom text under "Documents" link) is set to "YES",then the WF approval is required and the approvers are determined.
    The above logic works fine for the Standard type PO's where the difference between the old value and new value is determined using FM "BBP_PD_PO_GETDETAIL"  by passing the GUID (for the change version and the active vesion) obtained at runtime in the BADI.
    However for the limit type PO's,whenevr I change the total value for the Limit item,I see that the FM "BBP_PD_PO_GETDETAIL" doesnt return the changed value but  always returns blank!
    Bcause I need to check bth the values i.e. Custom text set to "YES" as well as Total value diff ,I cant use the start conditions in tcode SWB_COND.ALso I need to fetch the approvers based on the price diff so I need this value at runtime in the BADI using the FM "BBP_PD_PO_GETDETAIL".
    Please advise why the FM is not returning the changed values for the Limit type PO and is there any other way(other table/FM) to get the changed value at runtime for the LIMIT type PO.
    Thanks for your time.
    Edited by: Rads1234 on Nov 18, 2010 4:39 AM

    Thanks for the rpely.
    Yes.I am using the GUID available at runtime in the  BADI "BBP_WFL_APPROV_BADI" which is the current change version GUID.I tried using that GUID to get the data from both FM as well as CDHDR and CDPOS tables.
    I think this is something related to LImit type PO because for Standard type PO's the FM returns the corretc changed value (as in the screen) for the change version GUID.I fail to understand why the changed values are shwon on the screen but are not stored anywhere in the system before actually ordering the PO!

  • Pro*C & SQLDA with NULL value for predicate column

    Hi: I am using a C program to update a table via a dynamic sql (method 4) and SQLDA. In the update statement predicate, I have place holders (as in TBLCOL=:C000). One of the columns in the predicate contains null values, so I set L[n] = 0, V[n] = pData (which pData[0] = '\0'), *(I[n]) = -1, and T[n] = 5 (for text). I cannot find the row that I know is there.
    I cannot change my statement to contain TBLCOL IS NULL, since I don't know ahead of time if I'm looking for rows with null values for this column. The Pro*C manual says that by setting the appropriate *(I[n]) = -1, it indicates to Oracle to simulate the "IS NULL" clause, and update the appropriate rows. In my case, I receive 1403 as SQLCODE when I use TBLCOL=:C000 vs TBLCOL IS NULL. What am I doing wrong? Thank you for your help.

    You should include these columns as well;
    ChangeType (see mxi_changetype)
    ValOwner (repository)
    UserID ("jobid=<>", usermskey, GUI (mmc), DG (dyngrp), reconcile)
    IdAudit  (This is the event task (add and del member for assignments)
    ParentAuditId (AuditID of parent which last updated the attribute, not consistent)
    ChangedBy (Holds the MSKEY of the user which last changed the attribute)
    ExpiryTime
    to make sure you get a fuller picture of the audit record.

  • How do I set a NULL value for the parameter field

    Hi
    I've another question. I'm going to set single values for parameter fields.
    // e.g. set today for StartDate parameter field
    fc.setCurrentValue("", "StartDate", new Date());
    It should be possible to set a NULL value for date parameter fields.
    fc.setCurrentValue("", "StartDate", (Date)null);
    But this do not work. How do I set a NULL value correctly?
    Thank you in advance.
    Best regards,
    Thomas

    First question - is it a stored procedure parameter?
    You can't set a regular parameter field value to a null value.
    There was an issue with old version of the JRC, where it was allowing null to go through, but had unexpected behavior at times.
    Sincerely,
    Ted Ueda

  • How do I get a new value for the service name field and update it in Connection Properties?

    I am running Windows Vista. I just upgraded to Firefox 4. When I try to log on to the internet, it tells me the proxy server is refusing connections. A diagnostic reported Error 815 and said the remote server is not responding because there is an invalid value for the "Service Name" field. It said to get a new value and update it in Connection Properties. How do I do this?

    When you create a new film script, the first page you see is a title page.
    The page after this title page is the one where you generally type in your scenes.
    It looks like you are facing some issue and not able to delete any text.
    Can you please send me this script so that I can have a better look at your issue?
    You can save this script to disk by using option 'File -> Save to disk'. This will create a '.stdoc' file on your system.
    Just mail this '.stdoc' file to me at 'roverma <at> adobe <dot> com'
    Thanks

  • Can you set default values for person/group picker fields? To current user?

    Two-part question/issue . . .
    Part 1:
    In InfoPath 2013 in use with SharePoint 2013, how do you set a Default Value for Person/Group Picker fields? Other field types like Text Boxes have a Default Value section in the Data tab of Properties.  There doesn't appear to be any equivalent for
    the Person/Group Picker field type in Properties.  I'd like to set a default person for a few fields in a form I've created.  Is this possible?
    Part 2:
    The default user I want to set for one of those Person/Group fields is the "current user."  I want a user to log into our SharePoint 2013 intranet, load a new form for edit/creation, and have one of the Person/Group fields in that form to
    automatically populate this particular user.  Is this possible?

    Hi Stephen,
    You can auto populate your InfoPath farm with current user Name and all other property that you have in your User profile, you have couple of options.
    First you can make a secondary connection in your InfoPath form with user profile and can use the UserProfileService.asmx and call the GetUserProfileByName method. Here is the steps you can follow.
    http://blogs.technet.com/b/anneste/archive/2011/11/02/how-to-create-an-infopath-form-to-auto-populate-data-in-sharepoint-2010.aspx
    Secondly you can use JQuery and SPServices ,
    $().SPServices.SPGetCurrentUser function to populate the values with script to achieve the same in this case you no need to use InfoPath form just create simple text type column in SharePoint
    list and auto populate it with getting the current user Name from User Profile here is the scripts
    <script language="javascript" type="text/javascript" src="../../jQuery%20Libraries/jquery-1.4.2.min.js"></script>
    <script language="javascript" type="text/javascript" src="../../jQuery%20Libraries/jquery.SPServices-0.5.4.min.js"></script>
    <script language="javascript" type="text/javascript">
    $(document).ready(function() {
      var userCurrentName = $().SPServices.SPGetCurrentUser({
        fieldName: "CurrentUser"
      $("input[Title='CurrentUser']").val(userCurrentName);
      var userPhone = $().SPServices.SPGetCurrentUser({
        fieldName: "WorkPhone"
      $("input[Title='Phone']").val(userPhone);
    </script>

  • Using Convert to handle NULL values for empty Strings ""

    After having had the problem with null values not being returned as nulls and reading some suggestion solution I added a converter to my application.
      <converter>
        <converter-id>NullStringConverter</converter-id>
        <converter-for-class>java.lang.String</converter-for-class>
        <converter-class>com.j2anywhere.addressbookserver.web.NullStringConverter</converter-class>
      </converter>
    ...I then implemented it as follows:
      public String getAsString(FacesContext context, UIComponent component, Object object)
        System.out.println("Converting to String : "+object);
        if (object == null)
          System.out.println("READING null");
          return "NULL";
        else
          if (((String)object).equals(""))
            System.out.println("READING null (Second Check)");
            return null;       
          else
            return object.toString();
      public Object getAsObject(FacesContext context, UIComponent component, String value)
        System.out.println("Converting to Object: "+value+"-"+value.trim().length());
        if (value.trim().length()==0 || value.equals("NULL"))
          System.out.println("WRITING null");
          return null;
        else
          return value.toUpperCase();
    ...I can see that it is converting my values, however the object to which the inputText fields are bound are still set to empty strings ""
    <h:inputText size="50" value="#{addressBookController.contactDetails.information}" converter="NullStringConverter"/>Also when reading the object values any nulls are already converted to empty strings before ariving at the converter. It seems that there is a default converter handling string values.
    How can I resolve this problem as set nulls when the input value is an empty string other then checking every string in my class individually. I would really hate to pollute my object model with empty string tests.
    Thanks in advance
    Edited by: j2anywhere.com on Oct 19, 2008 9:06 AM

    I changed my converter as suggested :
      public Object getAsObject(FacesContext context, UIComponent component, String value)
        if (value == null || value.trim().length() == 0)
          if (component instanceof EditableValueHolder)
            System.out.println("SUBMITTED VALUE SET TO NULL");
            ((EditableValueHolder) component).setSubmittedValue(null);
          else
            System.out.println("COMPONENT :"+component.getClass().getName());
          System.out.println("Converting to Object: " + value + "< to " + null);
          return null;
        System.out.println("Converting to Object: " + value + "< to " + value);
        return value;
      }which produces the following output :
    SUBMITTED VALUE SET TO NULL
    Converting to Object: < to null
    Info : The INFO line however comes from my controller object where I print out the set value :
    package com.simple;
    import java.util.ArrayList;
    import java.util.List;
    public class Controller
      private String information;
      /** Creates a new instance of Controller */
      public Controller()
        System.out.println("Createing Controller");
        information = "Constructed";
      public String process()
        System.out.println("Info : "+getInformation());
        return "processed";
      public String reset()
        setInformation("Re-Constructed");
        System.out.println("Info : "+getInformation());
        return "processed";
      public String setNull()
        setInformation(null);
        System.out.println("Info : "+getInformation());
        return "processed";
      public String getInformation()
        return information;
      public void setInformation(String information)
        this.information = information;
    }I also changes my JSP / JSF page a little. Here is the updated version

        </f:view>
      </body>
    </html>The converter is declared for the String class in the faces configuration file. From the log message is appears to be invoked, however the object is not set to null.
    I tested this with JSF 1.2_04-b20-p03 as well as 1.2_09-b02-FCS.
    any other suggestions what could be causing this.

  • AJAX - How do we check if the response text returns a null value

    Hello,
    Could someone please help me with this issue?
    I am trying to disable a select box based on my responseText value.
    I need to check if my responseText is a null and disable my select if it is a null.
    Here is my code:
    if (xmlHttp.readyState==4)
              if(xmlHttp.status==200)     
              var getVal = xmlHttp.responseText;
              alert(getVal); //MY ALERT SHOWS A NULL     
              if(getVal == null) //but my null comparison fails
              document.all[ajaxBean.ajaxId2].disabled = true;               var valarray=getVal.split(",");
    else
                   for (var i=0; i < valarray.length;++i)
         var valarrayinner = valarray.split("|");               addOption(document.getElementById("secondBox"), valarrayinner[1], valarrayinner[0]);
    could someone tell me if its the right way to check for null value in responseText? or an alternative way to do the same
    Your help is appreciated!
    Thanks
    Priya

    Hello,
    Thank you for your promt response...I tried doing them as well. but nothing seems to work.
    It returns a length value of 1. It appears to be strange. I even tried to catch the null and set some junk text. When i try to check for the returned text again it returns a false.
    I dont know if this is the way responseText works. I tried setting a form variable but it doesnt do that too. Is there a specific way to check for the values in returned responseText?
    Thanks
