Column Null Or 0 Default Value

Feb 3, 2005

Hi





I have a table with the list of employee and 15 column with data type float or money , that represent the number of hours, airfare,gas,parking food, etc....





I have 2 choice:


-Put 0 as a default value for each column, like that I do not have to use coalesce when I do SUM for each column.


-Leave the default value null but I will have to use coalesce.





In term of performance, what is the best solution?





Thanks

Subscription Issue With Null Default Parameter - Key Cannot Be Null

May 3, 2007

I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.

The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.

Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.



An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help

Default Constraints NULL / Not NULL

Aug 2, 2015

I have 595 default constraints in my database. I can return a list of them using the following:

select * from sys.default_constraints

Is there a way I can return a list of just the ones where NULL is still allowed? I want to update all of the columns with a default value to not allow NULLs.

Question On Not Null With Default'

Jan 29, 2008

I have defined 8 varchar columns as not null with default, i.e.


[Namad8] [varchar](40) COLLATE Latin1_General_CI_AS NOT NULL DEFAULT (' '),


I run a script transformation (Flat file source, OLE DB dest) that splits a crlf delimited field an array, and then loads each array element into one of the not null table columns as above. However there may be less than 8 elements present in the input field, which means the remaining columns are not populated.

When I run the data flow task, I get the error
"

Error: 0xC020901C at Capture Assessments, OLE DB Destination 1 [1]: There was an error with input column "Namad8" (24) on input "OLE DB Destination Input" (14). The column status returned was: "The value violated the integrity constraints for the column.".


I know I'm trying to insert a null value into the column, but my understanding was that SQL would default the column to spaces. If I define the column to allow nulls, the data flow works fine.

Any idea what I'm doing wrong here?

SQL 2012 :: Can Default To 0 When Pass NULL Explicitly

Sep 23, 2014

I have a Nullable columns. I want the value to be zero if NULL is passed.

1) having a view for every such table,
2) using ISNULL for needed columns in that view
3) using those view for inserts instead of using tables directly.

This way i can reduce the number of places to use ISNULL in all my SPs.I dont want to make it to NOT NULL, as my application impact will be high. And Default constraint does not work here.

CANT We Set Default Value Null To Parameter In Stored Procedure

Feb 18, 2008



Hello

I've written a stored procedure with 4 parameters

create procedure dummy
( @a int, @b int, @c varchar(50), @d varchar(50))

now from front end(I'm using c#.net)
I want to send the values according to some criteria
So in the process...I've only values for @a & @c ...

so In order to reduce the code of sending Null values explicitly to other parameters...

can't I set like default values for it so that If I don't send values to certain parameters it will have the default value or Null value.

like I want something like this:

create procedure dummy
( @a int NULL, @b int NULL, @c varchar(50) NULL, @d varchar(50) NULL)

- Using Inner Join When The Field In My Data Table Has The Null Default Value:

Jul 16, 2006

I have a datatable : Data_Table  and a look up table: Lk_table. Myfield that I
use in Inner Join  is defined in both the
data and look table.

 

So I build my query like this:

SELECT     * FROM         dbo. Data_Table  INNER JOIN

                     
dbo. Lk_table ON dbo.Data_Table.MyField = dbo.Lk_table.Myfield

                

The pb, sometimes  I
have myfield still with its default null value in the datatable: Data_Table.
So, I end up getting 0 record when I execute the query shown above.

How do I turn that around so that even if myfield in Data_Table
is Null, I still get the records from Data_Table. (I don t want a set of
records including all possible values from the look up table: Lk_Table)

Quick Question... How To Use Default Values (after Allowing NULL)

Oct 17, 2005

Hello,

I have a BIT column which accepts NULL values.

What would be a good method to allow an INSERT (or UPDATE) statement to insert NULL into this column but then automatically change the NULL to 0 (zero). In other words, test for NULLs after INSERT (or UPDATE) and change the value to 0 (zero).

Not exactly sure how to do this with a Trigger. Also, what is that [Formula] option used for (column properties in the Table Design view)... and would this apply with my problem?

Thanks,

Reading Default Values Instead Of NULL From A Flat File

Oct 22, 2007

Hi,

I have the following problem: I'm connected to flat file source and trying to read data that is later inserted in an MS Access database. Everything wokrs fine instead of one thing - when I have null values in the flat file, I want those NULL values to be inserted in the MS Access db, instead of that what happens is that I actually get the default values for a column type from the flat file and later insert that defalut value. For example if I have a null value in an four-bite-signed-integer column of the flat file, I get 0 as value.

I thouth of solution using a "Derived Column" transformation which can transform the zeros into nulls, but decided to check with you guys if there is a smarter thing to do (for example to edit the flat file source to read the NULLs correctly).

Any advice is appreciated! Many thanks

Reporting Services :: DateTime Parameter With NULL Value Is Default

Jul 4, 2015

I have a report with datetime parameter which is required to be optional (there should be an option not to select this parameter which would cause in not narrowing result of this report by this parameter).

I used datetime parameter

@daTo (to have the calendar control for selecting date) and check on "Allow Null" value. Here is default Value.

I've also tried to set DefaultValue expression was "=Nothing".  

IN my query of data set, here is the part I use the parameter @daTo
 ... Where (@daTo IS NULL OR TRUNC(@daTo) >= TRUNC(pe.start_time) ....

But when I run the report, I got below error:

ORA-00932: inconsistent datatypes: expected DATE got NUMBER

I think it @daTo value actually not null so it try to TRunc the value

I don't know how to set null value default in my report.

Data Flow Task - Have Null Values Take Table Default

Jun 6, 2006

Hi,


I have a data transform from a flat-file to a SQL server database.
Some of the flat-file fields have NULL values. The SQL table I'm
importing into does not allow NULL values in any field, but each field
has a Default value specified.


I need to have it so that if a null value comes across in a field using
the data transform, it takes the table default on import. I could of
sworn I had this working a few days ago, but I get errors now that
state I'm violating table constraints. Has anyone done this before?


Thanks
Jeff

Hi all,

One of my columns is the table has some Null values, and I Would like to stop having NULL values into that column any more.

I know, If I alter the column to NOT NULL will throw me an error, since it does a batch update.

Is there any way to achieve this...

Default To NULL Instead Of Blank/empty String During Flat File Import

Aug 15, 2006

Hi,

In SSIS flat file import using fastload, I'm trying to import data into SQL 2005 previously created tables.

The table may contain column that are NULLable BUT there is NO DEFAULT for them.

If the incoming data from flat files contains nothing either between the delimeters, how can I have a NULL value inserted in the column instead of blank/empty string?

I didn't find an easy flag unless I'm doing something wrong. I know of at least two ways to do it the hard way:

1- set the DEFAULT(NULL) for EVERY column that needs this behaviour

2-set up some Derived Column option in the package to return NULL if the value is missing.

Both of the above are time consuming since I'm dealing with many tables. Is there a quick option to default the value to NULL WHEN there is NO data ELSE insert the data itself? So the same behavior that I have right now except that I want NULL in place of empty string/blank in the varchar(x) columns.



Thanks

Anatole

T-SQL (SS2K8) :: Cannot Define Primary Key Constraint On Nullable Column But Column Not Null

Sep 30, 2014

We have a database where many tables have a field that has to be lengthened. In some cases this is a primary key or part of a primary key. The table in question is:-

/****** Object: Table [dbo].[DTb_HWSQueueMonthEnd] Script Date: 09/25/2014 14:05:09 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[DTb_HWSQueueMonthEnd](

[Code] ....

The script I am using is

DECLARE@Column varchar(100)--The name of the column to change
DECLARE@size varchar(5)--The new size of the column
DECLARE @TSQL varchar(255)--Contains the code to be executed
DECLARE @Object varchar(50)--Holds the name of the table
DECLARE @dropc varchar(255)-- Drop constraint script

[Code] ....

When I the the script I get the error message Could not create constraint. See previous errors.

Looking at the strings I build

ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] DROP CONSTRAINT PK_DTb_HWSQueueMonthEnd
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] Alter Column [Patient System Number] varchar(10)
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] ADD CONSTRAINT PK_DTb_HWSQueueMonthEnd PRIMARY KEY NONCLUSTERED ([Patient System Number] ASC,[Episode Number] ASC,[CensusDate] ASC)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

They all seem fine except the last one which returns the error

Msg 8111, Level 16, State 1, Line 1
Cannot define PRIMARY KEY constraint on nullable column in table 'DTb_HWSQueueMonthEnd'.
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.

None of the fields I try to create the key on are nullable.
