How to fetch null values from DB

I need to fetch records where a field value is Null or nothing or space.
I tried :
where <field > eq space.
But this did not fetch any records though there are records in DB.
Is there any other way?
Thanks
Kiran

Hi kiran,
As you say, WHERE<field > EQ space should be works, try using WHERE <field > IS NULL..

Please help..it's Urgent..How to fetch the value from table row from Page

Hi,
I have created a table with 2 LOV's , LOV2 is dependent on LOV2.
Here I can not use the general Dependent LOV concept, as these values are coming from 2 different LookUps.
I am not able to fetch the user input for LOV1 (from page) .that is why not able to set the where cluse fro 2nd LOVVO.
I have used this code:
if ("ViolationCat".equals(lovInputSourceId)) {
OAMessageLovInputBean msglov =
(OAMessageLovInputBean)webBean.findChildRecursive("ViolationCat");
// String p_violation_category = "'"+(String)msglov.getValue(pageContext)+"'";
String p_violation_category =
(String)msglov.getValue(pageContext);
// System.out.println(" p_violation_category =" +
// p_violation_category);
String v_violation_category = "";
//System.out.println("vcat=" + vCat);
OAViewObject violationVO =
(OAViewObject)am.findViewObject("SNI_Violation_DtlsVO2");
Number vcatViolationIdnum =
(Number)violationVO.getCurrentRow().getAttribute("ViolationId");
String vcatViolationId = "" + vcatViolationIdnum;
pageContext.putTransactionValue("vcatViolationId",
vcatViolationId);
pageContext.putTransactionValue("p_violation_category",
p_violation_category);
String query =
" SELECT LOOKUP_CODE, \n" + " MEANING, \n" +
" LOOKUP_TYPE \n" +
" FROM apps.fnd_lookup_values \n" +
" WHERE LOOKUP_TYPE ='SNI_VIOLATION_CATEGORY' AND MEANING=?";
PreparedStatement ps = txn.createPreparedStatement(query, 1);
try {
ps.setString(1, p_violation_category);
ResultSet rs = ps.executeQuery();
//System.out.println("before while,");
// rs.next();
// v_violation_category = rs.getString("LOOKUP_CODE");
// System.out.println("v_violation_category="+v_violation_category);
while (rs.next()) {
//System.out.println("inside while");
v_violation_category = rs.getString("LOOKUP_CODE");
// System.out.println("v_violation_category=" +
// v_violation_category);
ps.close();
} //try ends
catch (Exception e) {
e.getMessage();
//System.out.println("in catch.." + e.getMessage());
OAViewObject subCatVO =
(OAViewObject)am.findViewObject("SNI_ViolationSubCategoryVO1");
//System.out.println("get VO before where clause: subCatVO::"+subCatVO.getQuery());
subCatVO.setWhereClause("LOOKUP_TYPE like '%SNI_VIOL_SUB_CAT_" +
v_violation_category + "'");
System.out.println("after set where clause VO: subCat VO::" +
subCatVO.getQuery());
subCatVO.executeQuery();
// System.out.println("query of subCat VO::" +
// subCatVO.getQuery());
//End of sub category Validation
It is working fine only for the 1st row of teh table.
I have tried to fetch the value using :
String violationCategory = (String)violationVO.getCurrentRow().getAttribute("ViolationCategory");
String violationSubcategory = (String)violationVO.getCurrentRow().getAttribute("ViolationSubcategory");
But it is fetching null value.
Please tell me how can I able to fetch the values.

Hi
in your scenarion,first u have to identify the particular row of table where the changes is being made ,u have to use this code .when u select the lov ,first it will give the row refernce and then u have to catch the lov event
OAApplicationModule am =
(OAApplicationModule)pageContext.getApplicationModule(webBean);
String event = pageContext.getParameter("event");
if ("<ItemPPREventName>").equals(event))
// Get the identifier of the PPR event source row
String rowReference =
262
pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
Serializable[] parameters = { rowReference };
// Pass the rowReference to a "handler" method in the application module.
am.invokeMethod("<handleSomeEvent>", parameters);
In your application module's "handler" method, add the following code to access the source row:
OARow row = (OARow)findRowByRef(rowReference);
if (row != null)

How to post null values from h:inputText?

Hello,
I have a form made of h:inputText fields that map to an entity class as the backing bean. Whenever I post the form from a web page, all the fields that I did not fill out and that are mapped to String fields in the entity class are set to "" (empty string) instead of null.
However, I would like to post null values to my entity, because that would indicate that the user did not fill out the field. In other contexts (outside of the web app) it is possible to set the fields to empty strings, but from the web app it should always be null. How can I get JSF to do this correctly?
Also, when reading entitys with null values from the database, these are converted to empty h:inputText fields, so this direction works as expected.
Ulrich

I haven't seen a solution for this as far.
This is how I do it:
public void action() {
    if (isEmpty(inputValue)) {
        // do your thing
    } else {
        // do your thing
public static boolean isEmpty(Object value) {
    if (value == null) {
        return true;
    if (value instanceof String && ((String) value).trim().length() == 0) {
        return true;
    if (value instanceof Collection && ((Collection) value).size() == 0) {
        return true;
    // And go so on .. make it an utility method.
    return false;
}

How to replace NULL values from main table

Dear all,
I like to remove the NULL values from a main table field. Or the question is how to replace any part of the string field in MDM repository main table field.
e.g. I have a middle name field partly the value is NULL in some hundreds of records, I like to replace NULL values with Space
any recommendation.
Regards,
Naeem

Hi Naeem,
You can try using Workflows for automatically replacing NULLs with any specific value.
What you can do is: Create a workflow and set trigger action as Record Import, Record Create and Record Update. So, that whenever any change will occur in the repository; that workflow will trigger.
Now create an assignment expression for replacing NULLs with any specific value and use that assignment expression in your workflow by using Assign Step in workflow.
For exiting records, you will have to replace NULLs manually using the process given by Preethi else you can export those records in an Excel spreadsheet which have NULLs and then replace all NULLs with any string value and then reimport those records in your MDM repository.
Hope this will solve your problem.

Varun

Fetching Null Value from table

I have a table where I am want to findout the total number of product (count of product) based on the ProdName.
I have the following table with two columns:
create table newproduct (prodid integer, prodname varchar(30));
Insert into newproduct values (100, 'TowerA')
Insert into newproduct values (160, 'TowerA')
Insert into newproduct values (170, 'TowerB')
Insert into newproduct values (120, 'TowerB')
Insert into newproduct values (140, 'TowerC')
Insert into newproduct values (180, '')
So here the query that I trying to use:
Select Distinct prodname from newproduct;
Select prodid from newproduct where prodname is null; /* Correct way */
Select prodid from newproduct where prodname in (''); /* I want result (180) by using this query */
How can I do it?

I'm not sure why you're trying to accomplish it that way, but you could try to use NVL to do that.
You just need to make sure whatever value you input in the NVL is something you won't ever obtain as a real column value.
Select prodid from newproduct where nvl(prodname, 'NULL VALUE HERE!') in ('NULL VALUE HERE!');Also, for performance reasons, since you're applying a function to the column, it won't be looking up indexes for matches, unless you create a function-based index.
Nulls are not indexed anyway, but I'm not sure what you're trying to do with this query.

How to include null values from DB

Hi,
I want to see all columns values even though it may contain null values. Right now all null columns are being suppresed by XSQL. Is there any way i can configure this.
Thanks in advance
Regards
Veera

use the following attribute in the <xsql:query> element (see the xsql help!):
<xsql:query null-indicator = "yes">..
</xsql:query>
Indicates whether to signal that a column's value is NULL by including the NULL="Y" attribute on the element for the column. By default, columns with NULL values are omitted from the output. Valid values are 'yes' and 'no'.(Default value is 'no')

How to remove null values from list?

I had created a list in forms 6i and I am getting list values at run time using add_list_item function. The problem is I am getting null value at end of the list. In the property pallet I kept required yes and set the initial value but it is not removing null value. Can any one help me. Thank you.......

Hello
Sorry mis-read question on first reply.
1. Have you set a default value?
2. Is this default value still in your list?
3. What happens if you default the list's value to a value you know exists after you have populated it?

How to pass null values From DTW

I have update value of Acctntcode of OACT table
Now i have to insert null in the field of Acctntcode From DTW (Data Transfer WorkBench)
How Can i do it ?

Hi,
little late to the party on this one but I had a similar issue today and found the answer.
Use a "/" (forward-slash) in your DTW file and it will set the field to NULL for you.
I don't know if this works for numeric fields (probably not) but it worked for me on several string fields I needed to clear in various Master Data objects.
HTH!

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

Hi,
Use NVL or COALESCE:
NVL (col_a, col_b)
Returns col_a if col_a is not NULL; otherwise, it returns col_b.
Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

How can I delete null values from List Item?

Hi Friends,
I used List item for field job_Type, I entered values in List item at design time through property pallet. When I run form I will see null values in this List Item.
How can I remove these null values from the List?
Best regards,
Shahzad

Dear Shahzad,
It can be removed by adding the following code in the When-new-Form-Instance.
Set_item_property('List name', required, property_true);
:block_name.list_name := <put your default value here>; (If you didn't oput the default value, then you will get some problem and the cursor may not navigate away from the list).
