Insert a null value?

does anyone know how to insert a null value?
For example:
insert into tbl_table (col1,col2)
values (null,null)
thanks.

insert into tbl_table (col1,col2)
values (null,null)
This query will insert null into the DB, if the column "NOT
NULL" property is false. Otherwise null can't be inserted into DB.
If "NOT NULL" is true then,
insert into tbl_table (col1,col2)
values ('','') blank value can be inserted, but not null.
Thanks

Inserting a 'null' value in an IF THEN ELSE statement

Greetings,
I'm using Business Object webi XiR3
I'd like to return a 'null' value in certain cases for an IF THEN ELSE statement. Depending on if I format the field as a text or a number, I can return blanks ("") and zeros (0). However, what I really need to do is leave the field / column formatted as a number and return a 'null' value. You can see the variable below ... this will return a blank but the column is text.
Suggestions?
thanks.
variable:
=If([Comp Rate Mid] = 0 And( ([Market Rate 50th].085) - [Annual Total Targeted Comp] >=0) ; ([Market Rate 50th]0.85) - [Annual Total Targeted Comp]; If([Comp Rate Mid] <> 0 And( ([Comp Rate Mid] 0.85) - [Annual Total Targeted Comp] >=0) ; ([Comp Rate Mid]0.85) - [Annual Total Targeted Comp];""))

I don't think this is possible using a formula, as formulas deal with content, and images can be placed in cells only as 'image fill', which is Format, rather than Content.
Might be possible using an AppleScript, but I'm not the person to advise you on that.

How to insert a NULL value in SQL using JDBC Adapter

Hi All,
I have a File -> JDBC scenario.
In the File and in the SQL table I have a column called "MR_DATE" that needs to be mapped
I have to do the following:
If MR_DATE is NOT equal to "00000000"
then pass MR_DATE to SQL table
else
set the MR_DATE column in the table as NULL.
Please suggest
regards,
Piyush

Hi Piyush,
In the receiver JDBC adapter select the option Interpretation of Empty String Values as NULL.
Pass date as empty, it will be interpreted as NULL by adapter and inserted in database.

How to insert a null value to combobox which is bind with datasource

Hi,
i am working on c# winforms application. I have 2 comboboxes one is CustomerCbBox and another is OrderCbBox. CustomerCbBox is bind with data source.
on CustomerCbBox SelectedIndexChanged event data is populated in OrderCbBox from data source.
i want to add a null or empty field in CustomerCbBox. all I want is that when the user don't Select Customer Name and OrderNo null or empty data enter in database. but when i click Insert Button it generate error "Object reference is not "object
reference not set to an instance of an object".
here is my code.
private void MainForm_Load(object sender, EventArgs e)
production pd = new production();
CustomerCbBox.DataSource = pd.Customer();
CustomerCbBox.DisplayMember = "Cust";
CustomerCbBox.ValueMember = "CustId";
private void CustomerCbBox_SelectedIndexChanged(object sender, EventArgs e)
try
string PartyName = CustomerCbBox.SelectedIndex.ToString();
PONum1.DataSource = pd.GetPOnumActive(PartyName1);
PONum1.DisplayMember = "PONum";
PONum1.ValueMember = "PONum";
catch (Exception ex)
MessageBox.Show(ex.Message);
Please help me to solve this problem thanks.

Hello,
We could check whether the user has selected any items before adding that to database.
if (CustomerCbBox.SelectedIndex > -1)
// do something
}else{//add dbnull to database}
And for adding null to databse, we could pass DBNull.Value instead.

Null value in Datetime field

I have a form that inserts data, but the date fields are getting a default value (1/1/1900 12:00:00 AM) even though I don't insert a value for that field. How would I insert a NULL value in the datatime fields in MSSQL.instead of the default value (1/1/1900 12:00:00 AM) that gets inserted?
Here is my insert statement.

Would CFQueryParam work? For example:
<cfqueryparam cfsqltype="CF_SQL_DATE" value="#DateLastUpdated#" null = "#YesNoFormat(NOT Len(Trim(DateLastUpdated)))#">
So, using your given example, your insert would be:

Component binding return null value

I'm migrating a JSF 1.2 application to JSF 2.1, specificly I'm currently using mojorra 2.1.24.
The application consists of request scoped beans, and in order to pass data between requests, it embeds the data inside UI components.
The following behaviour works well with JSF 1.2, but not with JSF 2.1.
The application has the following configuration:
<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>
The page contains the following snippet:
<h:form prependId="false">
     <h:inputHidden binding="#{bean.inputHidden}" />
     <h:panelGroup rendered="#{bean.rendered}">
      <h:commandLink value="onAction" action="#{bean.onAction}" />
     </h:panelGroup>
</h:form>
The bean is the following:
@ManagedBean
@RequestScoped
public class Bean {
private UIInput inputHidden;
private AItem item;
public setInputHidden(UIInput inputHidden){
    this.inputHidden = inputHidden;
    if(item != null){ this.inputHidden.setValue(item); }
public AItem getItem(){
    return (AItem) getInputHidden().getValue();
// other getter/setter
public String onNavToPage(AItem item){ this.item = item; return "page"; }
public String onAction(){ //... do something return ""; }
public boolean isRendered(){ return getProcessItem() != null; }
The steps are the following:
to navigate to page page the method bean.onNavToPage is invoked from within another page;
upon page rendering the bean.item is set as bean.inputHidden value;
after the page is diplayed, the command link is pressed.
At this point no command link is invoked, because the bean.inputHidden.getValue() returns null, and the command link is not processed.
I noticed that the inputHidden parameter passed to the setInputHidden method during restore view phase has, inputHidden.getValue() == null, no value has been saved previously in the view.
I would guess that something has changed in the component state management, but debugging the JSF code I didn't find what.
Debugging JSF code I found that the component state has been masked before the state has been saved in the view, so the ComponentStateHelper.saveState saves the deltaMap and not the defaultMap, where all the state has been put.
public Object saveState(FacesContext context) {
        if (context == null) {
            throw new NullPointerException();
        if(component.initialStateMarked()) {
            return saveMap(context, deltaMap);
        else {
            return saveMap(context, defaultMap);
is this a bug?
If not, how can I restore JSF 1.2 behaviuor and save the defaultMap?
Thanks in advance for the help.

NULL values are inserted into interface table for read only columns

Hi, I developed a custom Integrator where some of the columns has to be displayed as read only in the layout. I am using SQL content to populate the data. When I upload the data NULL values are inserted into table interface? Is there any work around for this?
Thanks

Doesn't WebADI drive you insane at times?
I must say, when it's all working it looks great and it is very user friendly (end-user that is, NOT for developers!) but before you get to that stage… please please Oracle invest some time making Web ADI a bit more logical an coherent, get the obvious bugs out, please let us not have to update BNE tables anymore to get things done.
Anyway, I sorted this one out by setting the Width to zero (0) in the Layout. HTH.

APEX post restful service inserts null value

Oracle APEX 4.2.5
Oracle Rest Data Service 2.0.7
Apache Tomcat 7
Oracle database 11.2.0.4
Oracle APEX PUT web service inserts null value into column. This is either a bug or the documentation does not properly cover how to correctly set PUT restful services.
GET web services works fine.
I have granted the role of apex_rest_public_user to both apex_public_user and the schema owner.
The payload is a small xml document, but even a text document will yield the same result.

Thank you,

I am experiencing the same issue.
I implemented the 'chunked file loading' example from Kris Rice's blog at Kris' blog: August 2013 in y workspace at the Oracle hosted APEX site and everything works fine.
However, I get a null value for 'data' when I implement the same example at my work site.
Work Site config is
Apache Tomcat 7
Oracle REST Data Services version : 2.0.6.27.18.06
Application Express 4.2.2.00.11
Oracle RDBMS 11.2.0.3
I am NOT using SSL at my work site. However this does not seem to affect a POST with form values.

How to transfer database table contain null values, primary key, and foreign key to the another database in same server. using INSERT method.

how to transfer database table contain null values, primary key, and foreign key to the another database in same server. using INSERT method. thanks

INSERT targetdb.dbo.tbl (col1, col2, col3, ...)
SELECT col1, col2, col3, ...
FROM sourcedb.dbo.tbl
Or what is your question really about? Since you talke about foreign keys etc, I suspect that you want to transfer the entire table definition, but you cannot do that with an INSERT statement.

Index (or not) for excluding NULL values in a query

Hello,
I have table that can become very large. The table has a varchar2 column (let's call it TEXT) that can contain NULL values. I want to process only the records that have a value (NOT NULL). Also, the table is continuously expanded with newly inserted records. The inserts should suffer as little performance loss as possible.
My question: should I use an index on the column and if so, what kind of index?
I have done a little test with a function based index (inspired by this Tom Kyte article: http://tkyte.blogspot.com/2006/01/something-about-nothing.html):
create index text_isnull_idx on my_table(text,0);
I notice that if I use the clause WHERE TEXT IS NULL, the index is used. But if I use a clause WHERE TEXT IS NOT NULL (which is the clause I want to use), a full table scan is performed. Is this bad? Can I somehow improve the speed of this selection?
Thanks in advance,
Frans

Null Values from a Data Source

This is more of an implementation question than a
troubleshooting question. Also, since I've been unable to find any
documentation on this I was wondering if anyone has come across
this behavior or found a bug with it.
Yesterday I was working on an application to explore some
proof of concept aspects of Flex for an application I'm developing.
I started running into a problem with Flex Data Services throwing
back an 'Unknown Property: "clientaddress1"' error whenever I tried
to update data. It seemed that whenever I tried to update a record
in the database it would thrown the Unknown Property error. I spent
a good chunk of the day trying to figure out what was causing this
and finally gave up and called it a day.
This morning I was reassessing what the problem was and
trying to find the differences between my database and my code and
I stumbled upon the fact that I could add no records and modify
them without a problem, however if I tried to access an existing
record and update it I'd get the Unknown Property error.
I start analyzing the database and found that I'd configured
the database to use null values for empty values and the records
that I created with the database had null values, however, any of
the values inserted from Flex were inserted as blank values. As
matching my action script class as clientaddress1 = ""; So, upon
further testing I fould that Flex was not processing the null
values correctly, so that when it came back and rightly generated a
Conflict Error...and then called AcceptServer() it was unable to
find the clientaddress1 property of the class.
Also, if any of the properties in the database are null it
throws the same error. Basically it seems to have invalidated the
object just because one value was null. So if all of my values from
the DB are set to something and only one field is set to null it's
still throwing the error on the first alphabetical item of the
properties.
I can resolve the problem by not using null values in the
database, but...what sort of effect would this have on someone
working with a large legacy database that extensively uses nulls
for undefined values?
Also, if a Flex guru could explain the reasoning for this
happening I would greatly appreciate it!

I realize that I didn't clarify that I am using ColdFusion
for getting the data. This class was generated by the Create CFC
wizard in Flex Builder.

Null value in poplist

Hi,
I'm using forms6i, I'm having a poplist in my form, which i populate in when-new-form-instance.
So when i open the form, and try to select one value, i'm seeing one null value, and if i select one value from list and again try to change the value then the previous null value is gone.
So to avoid that in when-new-form-instance itself , i assigned one value to the poplist using Get_List_Element_Value.
But the problem is since i'm assigning value, the form goes in insert status, and so even if i dont enter any valuees and try to exit, it is asking Close Form? (because i have few non-null items also).
How can i get one safe solution (like as it work when we assign some static values to the poplist).
ie i dont want nulls to be seen iin the list also i dont want the close form? message
I tried one solun by setting the form status as new again in w-n-f-i. But since i have multirecord block, this problem comes with every record.
Please suggest one better solution

Hi Divya
why don't u try putting the same code of the w-n-f-i in when-validate-record or when-new-record-instance may be it work...
if not working pls share us the code what about an example:
declare
rg_name varchar2(40):='r_area_record1';
rg_id Recordgroup;
LIST_ID ITEM;
errcode NUMBER;
begin
rg_id:=Find_Group(rg_name);
if Id_null(rg_id)
then
rg_id :=Create_group_from_query(rg_name,
'select VC_ID , research_area from research_info
where proff_id= 9');
LIST_ID:=FIND_ITEM('TRY_BLOCK.TRY');
end if;
errcode:=populate_group(rg_id);
POPULATE_LIST(LIST_ID,RG_ID);
end; Regards,
Abdetu...

Null value in a select-option

Hi all,
I have the follow question:
can I populate a range vith a null value?
I have a field in a standard table which can be "space" or "null". But if I insert:
sign = I
option = EQ
low = space
records with "null" field aren't extracted by the select statement. So is there any way to populate:
low = null or something similar?
Best Regards,
Raffaele Frattini

If the field is of type char then you need to wrte the same in quotes woth caps
else
declare
constants : c_null type i value '0'.
then assign the same
You check the null value using INITIAL laso.

Insert a null value?
