How to select instances without null value?

hye all,
i need to do th ereprocessing data whereas i have to select the instances without null value from the database..
for example:
id name
123 izza
345 alex
567
the id = 567 contain null value..so..its automatically will not be selected from the database...
how about if it have about 10 or more attributes to be selected..
how can i work with the SQL thanks..

Hi,
Query for your example should like like this:
SELECT * FROM <your_table>
WHERE name is null;
how about if it have about 10 or more attributes to be selected..
If using 10 or more attributes you mean 10 or more columns with null use this:
SELECT * FROM <your_table>
WHERE <col1> is null AND <col2> is null etc...Peter D.

How to select columns with null values

HI
In my table ‘A’ I have 10 columns and 30,000 records. I need all those columns whose value is null for all the records.
For example in the below table column 'suffix' is null for all the records. So I want column suffix to be selected.
Name Suffix Street
James 1100 Washington street
Richard 273 GEORGIA ST
Arnold 3018 OAKHILL AVE
MICHAEL 834 E 161ST ST
Joseph 410 PINE AVE
Thanks in advance

True...
But, i think here null needs to handle otherwise it will again throw some error like this ->

How does APEX check for null values in Text Fields on the forms?

Hello all,
How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
Declare
v_valid boolean;
Begin
IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := FALSE;
ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := FALSE;
END IF;
return v_valid;
END;
My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
Thanks

See SQL report for LIKE SEARCH I have just explained how Select list return value works..
Cheers,
Hari

How can I avoid the null values in cross tab?

How can I avoid the null values in cross tab?

Hello Anindita,
Let me explain you the problem in detail.
I have selected User and Program as rows in the cross tab. In Summarized Field I am counting the Programs.
In DB I can have both User and Program null.
Letu2019s take these scenarios...
1) For a User, Program can be null
2) For a Program, User can be null
3) And both can be null.
A null Program does not give problem since Cross tab does not count the null values and in my case too, it remove the Program which are null from the Cross tab because of the counting its doing on Program. Hence scenario 1 and 3 is not a Problem.
Problem comes in scenario 2 (For a Program, User can be null).
In this case since Program is not null it will get counted and will be grouped under null user but I donu2019t want to show the null user Grouping in my cross tab.
"Suppress empty rows" and "suppress empty colums" does not help.
Thanks & Regards,
Amrita

How do I pass a null value to the reportDocument?

I'm using CR 2008 and VS 2005.
I am using a stored procedure as the datasource for one of my report, which we run using the C# API.   The stored procedure is expecting a NULL in certain cases and I find I cannot pass a NULL with my current code:
// Here I get the parameter
// If we are dealing with an empty string or a NULL value, let's give it
                        // a value of a space so that Crystal's DLLs don't choke.
                        if ((value.Length == 0) || (value == "NULL"))
                            value = " ";
                        arrParams.Add(value);
Object strParam = arrParams<i>;
this.reportDocument1.SetParameterValue(num, strParam);
The stored procedure parameter type is INT so in the report it shows up as NUMBER.
How do I get a NULL value to the stored procedure?
Thanks.

See if this does the trick:
Dim crParameterDiscreteValue As New CrystalDecisions.Shared.ParameterDiscreteValue()
crParameterDiscreteValue.Value = Nothing
C# would look something like;
CrystalDecisions.Shared.ParameterDiscreteValue crParameterDiscreteValue;
crParameterDiscreteValue = new CrystalDecisions.Shared.ParameterDiscreteValue();
crParameterDiscreteValue.Value = null;

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 to replace BLANK or NULL values in rule file

Hi,
I have a source file which contains Blank or Null values which i need to replace them with a number "042" .How we can do this in the rule file using "Replace "(Field->Properties).I tried keeping spaces but its failing. I am actually new to essbase please let me know how we can do this.
Thanks in Advance

Hi,
Unfortunately you can't replace blank/null/space values directly. What you need to do is add a text field in your rules file first, then merge the text field with the column containing blank/null/space. Then you can use some creative find and replace to solve this problem.
For example, I often add a column called "TextCleaner" to my rules files where I suspect b/n/s values. After merging there are 3 possible options for the value.
1) "TextCleaner" (The original value was null)
2) "TextCleaner " (The original value was space)
3) "TextCleanerUSA Region" (The original value was valid data, such as USA Region)
Now you can use the find and replace as follows
First, F&R to remove any instance of "TextCleaner" and replace with 042. Be sure to check the "Match Whole Word" button. This swaps null values with 42
Second, do the same thing but with "TextCleaner ". This swaps any space/blank values with 42.
Third, replace "TextCleaner" with nothing. Do not check the "Match Whole Word" button. This changes any original valid values back to the original value.

How to query for a NULL value?

Hi all,
how can I query for a NULL value in a ViewObject. I tried to set null as where-clause param [setWhereClauseParam(0, null)]. But the created statement looks like this:
SELECT ...
FROM ...
WHERE param = null
I would expect it to create something like WHERE param IS NULL. I hope anybody has a solution for this.
Thanks,
Axel

I think you should use setWhereClause("COL_NAME IS NULL")
You could use setWhereClauseParam(0, "NULL"), but only if you have a predefined query similar to: "SELECT X, Y, Z FROM A WHERE X IS :0" (which is a pretty useless query, as you can ONLY set "NULL" as the value for ":0").

How to find out the null values in table

hi experts,
my version is oracledb10g:
i h'd simple doubts.
for eg:
create table ex1( e varchar2(20));
insert into ex1 (null).
insert into ex1(e)
count will be: 2
i can easily found out the value 'e'.
so my question is:
how can i found out the null values in the table and i want to delete the null values from the table.

delete from <table_name>
where <column_name> is null;Ideally you'd just place a NOT NULL constraint on the column in question, thereby prohibiting NULL values from entering into the system (assuming your business requirement is that the column MUST always have a value).

How to Select More then 1000 values in Multi-Select prompt!!!

Hello Users,
I have Scenario where i have to pass all the values from prompt to report and the values in the prompt are coming from session variable, so whatever value access user has the report will run with that only...
Now the question is that Multi-Select Prompt is not able to take more then certain values, so is there any way that we can increase the limit for selected values??
in-short how to increase the limit for selected values in multi-select prompt??
Thanks In Advance!!!

Hey David,
The Scenario is like, we have data level security on "Unit" attribute. now based on the user selection when user logs in he should able to see the report only for those units which he/she has access.
in total we have 1800 units available, now for 5-10 units access is fine, but the question will arise when user will not have only some units access from 1800 units.
because report will not take those values from the multi-select prompt reason is that multi-select prompt is not able to take more then certain values in selected side.
now in multi-select until-unless u have data coming in selected side those values will not pass. so i have kept the sql in default for that prompt.
so when user logs in he will able to see those values in selected side for the multi-select prompt, but when values increase from some level it's going automatically in un-selected side.
i want everything on selected side of multi-select prompt.
Let me know if you need any further details.

How to Select each check box values in a group of records

Hi,
I have a requirement in forms 10g. In that form there are 10 records are displaying each record has one check box is there if i click the check box on record number one and record number three and do some changes in the text field(adjustment field is number data type) then finally I want to see the total on one field called total amount.
In this my question is how to select particular records in a group of records? and finally these selected records are inserted into one table.
Because I am not able to fetch these records at a time.
Is there any Array to define a record group to fetch each of them individually for example Rec[1],Rec[2]...like that if yes please suggest me the steps how to do this.
Thanks in advance
Prasanna

I'm sorry, but i didn't get your requirement in detail.
Do you want to do the summing of the selected records in forms ? Or do you just want to know which records are selected and then process them?
If you want to process the selected records in sql you could use an object-type to store the list of id's (of whatever primary key you use), loop over the block to fill it, and then afterwards process them.
For this approach, first create an object-type in the database:
CREATE OR REPLACE TYPE ID_LIST AS TABLE OF NUMBER;
/Then, in forms you could do something like this to fill a list of id's:
DECLARE
lIds ID_LIST:=ID_LIST();
BEGIN
GO_BLOCK('MYBLOCK');
FIRST_RECORD;
LOOP
    EXIT WHEN :SYSTEM.RECORD_STATUS='NEW';
    IF :BLOCK.CHECKBOXITEM="CHECKEDVALUE" THEN
      lIds.EXTEND(1);
      lIds(lIds.COUNT):=:BLOCK.PRIMARYKEYITEM;
    END IF;
    EXIT WHEN :SYSTEM.LAST_RECORD='TRUE';
    NEXT_RECORD;
END LOOP;
-- Now you can use the object-list in SQL like :
INSERT INTO MYNEWTABLE (cols..)
SELECT (cols..)
    FROM MYOLDTABLE
   WHERE ID IN (SELECT COLUMN_VALUE FROM TABLE(lIds));

Selecting rows with null values in an sql 3 table

Hi everyone I use oracle database 11g and have the following SQL statement:
SELECT Oprema.Opr_Id, Oprema.Datum_Nabavke, Oprema.Datum_Zaduzenja, Oprema.Dobavljac, Oprema.Jedinica_Mjere,
     coalesce ((Oprema.Zaduzio), 0), Oprema.Vrijednost, Oprema.Kolicina_Nabavna, Oprema.Kolicina_Otpisana, Oprema.Kolicina_Trenutna, Oprema.Status, Oprema.Konto,
     Oprema.KontoIsp, Oprema.Broj_Naloga, Oprema.Sifra_Objekta, Dobavljaci.Naziv AS DobNaz, coalesce(to_char(Uposlenici.Prezime), 'hm'), Objekti.Objekat_ID
FROM OPREMA Oprema, UPOSLENICI Uposlenici, DOBAVLJACI Dobavljaci, OBJEKTI Objekti
WHERE Oprema.Dobavljac=Dobavljaci.Dob_Id AND Oprema.Zaduzio=Uposlenici.UposlenikId AND Oprema.Sifra_Objekta=Objekti.Objekat_IDWhat I need is to show all the rows in the database. The problem is that some of the foreign keys Zaduzio and Objekti are NULL. This means the databse won't show those and only shows me rows where both have values. In all of these rows except for 3 only one of the two foreign keys has a value.
So what I need is an sql that would show me all 3. As you can see I tried with Coallesce but it didn't work, still only 3 rows show.
I also tried with UNION
SELECT Oprema.Opr_Id, Oprema.Datum_Nabavke, Oprema.Datum_Zaduzenja, Oprema.Dobavljac, Oprema.Jedinica_Mjere,
     Oprema.Zaduzio, Oprema.Vrijednost, Oprema.Kolicina_Nabavna, Oprema.Kolicina_Otpisana, Oprema.Kolicina_Trenutna, Oprema.Status, Oprema.Konto,
     Oprema.KontoIsp, Oprema.Broj_Naloga, Oprema.Sifra_Objekta, Dobavljaci.Naziv AS DobNaz, Uposlenici.Prezime, Objekti.Objekat_ID
FROM OPREMA Oprema, UPOSLENICI Uposlenici, DOBAVLJACI Dobavljaci, OBJEKTI Objekti
WHERE Oprema.Dobavljac=Dobavljaci.Dob_Id AND Oprema.Zaduzio=Uposlenici.UposlenikId AND Oprema.Sifra_Objekta=Objekti.Objekat_IDBut then the rows that have both Zaduzio and Objekti values are multiplied and selected twice.
So any ideas on how to do this?

Hi,
If those foreign keys are NULL, then an inner join won't produce any results. Maybe you need to make it an outer-join, like this:
SELECT Oprema.Opr_Id
,      Oprema.Datum_Nabavke
,      Oprema.Datum_Zaduzenja
,      Oprema.Dobavljac
,      Oprema.Jedinica_Mjere
,     COALESCE ( Oprema.Zaduzio
           , 0
           )          AS zaduzio_or_0
,      Oprema.Vrijednost
,      Oprema.Kolicina_Nabavna
,      Oprema.Kolicina_Otpisana
,      Oprema.Kolicina_Trenutna
,      Oprema.Status
,      Oprema.Konto,
     Oprema.KontoIsp
,      Oprema.Broj_Naloga
,      Oprema.Sifra_Objekta
,      Dobavljaci.Naziv     AS DobNaz
,      COALESCE ( TO_CHAR (Uposlenici.Prezime)
           , 'hm'
           )          AS prezime_or_hm
,      Objekti.Objekat_ID
FROM            OPREMA
JOIN            DOBAVLJACI ON   Oprema.Dobavljac      = Dobavljaci.Dob_Id
LEFT OUTER JOIN      UPOSLENICI ON       Oprema.Zaduzio     = Uposlenici.UposlenikId
LEFT OUTER JOIN OBJEKTI     ON       Oprema.Sifra_Objekta = Objekti.Objekat_ID
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Simplify the problem. For example, if you really need to display 18 columns, but 15 of them have nothing to do with the problem, then post a question that just includes e or 4 of those columns.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

Thanks prety much,I am using XML to upload data from there into RTF templete. I've already insert table through load data option, but my problem is, how could I select a value from a list of values and based on that value selected from the list, it should displaydata corrosping to it. For example, I have few codes like TTAG, AMAG, TOTOM and if I select TOTM, it should display the complete address of that hotel named TOTM. If above given scenario is not at all possible, then Is there any alternate method to achieve this?

but I get a null valueThe method rettext() returns the String text, which only gets assigned a value after the button on the TextEnter gets clicked. Try assigning text a default value and see if that helps.

How to select instances without null value?
