Restrict null values

Hi all

Can I restrict null values when passing parameters in procedures. can someone explain to me with a small example

Hello

Pascale says:
The table does not allow null values. It throws an exception when the value null is passed IN parameter

Are you talking about raising of arguments passed to a procedure or a table?

If a column in the table has a NOT NULL constraint, an error will be reported in the world tries to add a NULL value in this column, or if someone tries to change an existing value with a NULL value.

I don't know anyway auto to force an error when a procedure is called with a NULL argument. There may not be any built-in mechanism because it is so easy to test the NULL at the beginning of the procedure and explicitly to trigger an error.

  • SQL query to restrict null values

    Hello

    I have the following table
    Procurement_id         estimate_end_date          revenue
    
    1                              01-oct-2012                   $1000
    2                              02-oct-2012                   $1500
    3                              01-dec-2012                   $300
    4                              01-jan-2013                    $500
    5                              21-Nov-2013                   $900
    .
    .
    .
    I want only the procurement_ids that have a date of estimated that between 30 and 60 days. and if its estimated finish date is within 30 days, I show that a column monthstoend as 1 and in the 60s would be 2.

    If the output would be something like
    ProcurementId   Monthstoend   revenue
              1                  1              $1000
              2                  1              $1500
              5                  2              $900
    Basically, I want to remove all null values. the query I came was

    Select
    procurement_id,
    (case when (estimated_end_Date - sysdate) < = 30 then 1)
    When (estimated_end_Date - sysdate) between 21 and 60, then 2
    on the other
    null
    end) montstoend
    recipes
    Of
    Table;


    Is there a way to eliminate NULL values in the same query. I know that we can query on top of this request and then to eliminate NULL values, but I was wondering if we can do it in the same query. I use a similar in a much larger request functionality, if want to avoid that if possible.

    Any suggestions?

    Thank you

  • How to restrict Null values

    Dear all,

    I have the main query... And I wrote a query for the delivered quantity.

    The query retrieves the accurate data. And when I add the query in main query comes with extra null data.

    e.g. query for amount emitted fetches 16 records.
    and I run the main question fetches 20 records... there r Archives 4 who issued the amount is null.

    How can I limit who registers.

    Thank you.

    Add in which the condition

    where column_name is not null
    
  • Properties: Treatment of NULL values

    I wanted to ask you how you deal with NULL values, on the properties of JavaFX.

    Properties of the wrapper for the primitive data types like SimpleIntegerProperty or SimpleBooleanProperty Don t accepts NULL values.

    Example:

    1. IntegerProperty integerProperty = new SimpleIntegerProperty() )
    2. integerProperty. setValue (null) ;
    3. System. out. println () integerProperty. getValue ());

    Output is 0 (default value for "int").

    I think the primitive property wrappers (IntegerProperty, BooleanProperty and friends) as of the wrappers for primitive types. Probably they shouldn't really inherit WritableValue as which allows the call to setValue with a type reference, but I think that indigestion API would be worse than the implementation of setValue with a slightly incorrect signature. I would just avoid defining a wrapper of primitive type to null property: If you want to restrict yourself using set (.) instead of setValue (...) you are forced to spend in the primitive type: either you cannot pass null.

    If you want an integer property where null values are handled in an intuitive manner, use ObjectProperty .

    The test below shows that call setValue (null) on IntegerProperty assigns the default value. (Although I don't see the behavior documented anywhere).

    import javafx.beans.property.IntegerProperty;
    import javafx.beans.property.ObjectProperty;
    import javafx.beans.property.SimpleIntegerProperty;
    import javafx.beans.property.SimpleObjectProperty;
    import javafx.beans.value.ChangeListener;
    import javafx.beans.value.ObservableValue;
    
    public class PrimitivePropertyWrapperTest {
    
        public static void main(String[] args) {
            IntegerProperty integerProp = new SimpleIntegerProperty();
            integerProp.addListener(new ChangeListener() {
    
                @Override
                public void changed(ObservableValue observable,
                        Number oldValue, Number newValue) {
                    System.out.println("integerProperty changed value from "+oldValue+" to "+newValue);
                }
            });
    
            ObjectProperty objectProp = new SimpleObjectProperty<>();
            objectProp.addListener(new ChangeListener() {
    
                @Override
                public void changed(ObservableValue observable,
                        Integer oldValue, Integer newValue) {
                    System.out.println("objectProperty changed value from "+oldValue+" to "+newValue);
                }
            });
    
            integerProp.setValue(null);
            integerProp.setValue(1);
            System.out.println("setting integerProp back to null:");
            integerProp.setValue(null);
            System.out.println("setting integerProp to 0:");
            integerProp.setValue(0);
            integerProp.setValue(null);
    
            objectProp.setValue(null);

  • NULL values for some elements of the XML reading tree

    I am confirming that I interpret correctly all the elements of a custom data XML structure defined by my application (the schema is completely under my control).  Some of the elements in my XML tree are read as NULL values, even if similar items are readind as expected.  I have checked some obvious things like misspelling the names of keys, but have not yet find the problem.  Anyone who has debugged similar questions - what else could cause this?

    Example XML:

    
        1.0.0.0
        1000
        MyAppsName
        
            
                1000
                userDefined
                StructName
            
        
    
    

    And extracted C++ w/comments at the end of each line about what I see (DataManager is my class of CRUD operations):

    In DataManager.hpp:

    QVariant mCustomDataStructsTopLevel;
    QVariantMap mCustomDataStructsTopLevelMap;
    

    In DataManager.cpp:

    mCustomDataStructsTopLevel = mXda.load(Utils::dataFilePath(customDataStructsFileName));  // XmlDataAccess; verified loading w/no errors
    mCustomDataStructsTopLevelMap = mCustomDataStructsTopLevel.toMap();
    
    qDebug() << "appName element value: " << mCustomDataStructsTopLevelMap["appName"]; // Outputs "MyAppsName" as expected
    qDebug() << "lastId element value: " << mCustomDataStructsTopLevelMap["lastId"]; // Outputs null (specifically: QVariant(, ) ) - this is NOT expected
    qDebug() << "appVersion element value: " << mCustomDataStructsTopLevelMap["appVersion"]; // Outputs null (specifically: QVariant(QString, "") )  - this is NOT expected
    

    OK, I got the feeling (and actually hoped) it was a silly mistake of face-palm on my part (compared to a problem of BB10 who had little chance of getting fixed).

    The problem is that I copy the structure of custom data from Starter to my Active dir to my data directory to first install but do not crush him on subsequent launches, as the copy in the data directory is what the user changes and relies on.  I was not a delete and reinstall on each of my iterations, so I wasn't really loading the modified versions of my XML I wanted--just, I was getting a day old stale version which was actually for the items I didn't expect NULL values for nulls.  DOH!

  • PersistentStore.getPersistentObject returns the null value?

    I use a random key to retrieve a shape of the object PersistentStore

    persist is PersistentStore.getPersistentObject (KEY);.

    Works fine on the Simulator (OS 5), when I take the code signed to the device (BB OS 5.0 Bold 8900)

    For some reason, it returns null, without exception. Thereafter any API I inoke on PersistentStore / persist returns null without exception persist even when the null value.

    I don't know if it's one thing to eclipse debugger, but even if the debugger shows that objects are null. Controls null applied in the code seems to fail, what does code see these objects as non-null. Pheww! How is it possible.

    In this code still shows up as null, then safetyTable and orderedkeys. However, the value null check in the failure code.

    At a later stage in the code, when I try to access orderedkeys are null again! Are struggling with this problem for two days, all the pointers would be very comfortable.

                        persist = PersistentStore.getPersistentObject( KEY );
                        persistOrderedKeys = PersistentStore.getPersistentObject(KEY_ORDERED_KEYS);
                        safetyTable = (Hashtable)persist.getContents();
                        orderedKeys = (Vector)persistOrderedKeys.getContents();
                        if (safetyTable == null)
                        {
                            safetyTable = new Hashtable();

                        }

                            {
                                Enumeration addressKeys = safetyTable.keys();

  • How to implement 'Null value replace' inside a RTF

    Hello

    This is my area:

    <? for-each - group:current-group(); / RP_CURRENCY? >

    <? If: RP_CURRENCY = "ABOVE"? >

    <? for-each - group:current-group(); / RPT_DESCRIPTION? >

    <? If: RPT_DESCRIPTION = 'debit card '? >

    <? sum (current - group () / RP_CI_EQUIVALENT_CALC)? >

    <? end if? >

    <? end for each group -? >

    <? end if? >

    <? end for each group -? >

    If this field does not always reach the sum, and then returns a NULL value. I need it to return 0 instead, but I think I'm this overload since RTF are not flexible.

    I tried to reach '+ 0' at the end and it works when its null, but if the number is not null, then it adds a 0 to the result rather than adding it.

    The XML code is attached.

    Please use this amount

    My question is that how to avoid this error.

    Concerning

    You can do a null control in your expression.

    If (Staxrate! = null & Salestax! = null) {}

    Return ((Purqty*Unitpurprice) + (Purqty * Unitpurprice) * Staxrate/100)

    }

    You can do this in a single DELETE statement (it is not a request), using an EXISTS or IN the subquery.  For example:

    REMOVE table_x m

    WHERE the value IS NULL

    AND THERE ARE)

    SELECT 0

    FROM table_x s

    WHERE s.id = m.id

    AND s.node = m.node

    AND s.value IS NOT NULL

    )

    ;

    If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test it.

  • NULL values in partition Table of Partition key

    Hi all

    I'm using Oracle 11.2.0.3.

    I can add a null value on partition of Partition table key.

    If so, how?

    Kind regards.

    • You cannot specify NULL in the VALUES clause.

    Referring to clauses PARTITION you set - not the data that you insert.

    If you cannot define a range partition that uses the VALUES LESS THAN and use null to this division. But you CAN use NULL values in the VALUES of integration clause.

    DROP TABLE mytable;

    CREATE TABLE MyTable

    (

    CREATION_DATE DATE,

    Identification number

    )

    PARTITION BY RANGE (CREATION_DATE)

    (

    PARTITION prior_to_2016 VALUES LESS THAN (TO_DATE ('2016-01-01', 'YYYY-MM-DD'));

    LESS THAN PARTITION of VALUES undesirable (MAXVALUE)

    )

    Insert into myTable values (null, null)

    You can use a VALUES clause to insert NULL values - this line will go into the MAXVALUE partition.
