Default Date When Not Null?

Apr 23, 2008

I have a table that has a date field that can't be null.  When a new record is created, if a date is not passed in, I want the default to be the current date.  How can I set that?  I tried Now, Today, GetDate, etc.

Date Picker Bug - Drops The Default Value And Displays Default Value As Todays Date

Apr 3, 2008



Hi,
Does anyone have a workaround or know of a fix to this problem:
Default value set to 'date pick' from date currently within field by setting value equal to that field . ie if date is 01/01/2010 date picker opens in Jan 2010 - works ok.
However, once published to Sharepoint and run through browser the Date Picker ignores the default value and the date picker opens for today. ie April 2008.


Any words of wisdom gratefully recieved,

Howard Stiles

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




Key cannot be null. Parameter name: key

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.

Default Date(current Date) Function W/ Update?

Mar 10, 2008

I have a reference table that currently has no web front-end. It's a small table(<10 rows) that's not going to change very often (maybe once every few months).

We manually update rows on the table via the GUI table interface in Enterprise Mgr., not in T-SQL.

What I'd like to do is have SQL Server automatically update the "Last_Modified" column with the current timestamp. I can do it on an Insert using the GetDate() function, but if I update a row, this doesn't work.

Is there a function I can use that can auto-populate for both insert and updates?

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

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

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

How To Set Date As Default

Dec 7, 2005

Hi, I probably do something stupid, but I cannot figure out how to set the date as deault when
inserting a record in a table. I have created a Default in the database, giving it a name and the Value = GetDate() and bind it to the desired column.
 
When I insert a record without filling in a value in this datefield, the table shows me "01/01/1900" in stead of Today.
 
What am I doing wrong ?
Help is appreciated, Ger.

Default Date

Apr 17, 2008

I am developing reports against OLAP cube. I can select the date (calendar year) or Month Name from the date dimension to display as a parameter to the report. But, when I show that parameter drop down, how do I default the value for the current month or year? I tried the default values in the report parameters as a non-queried value writing an expression, but whatever I write there, it ignores when showing drop down. Any ideas?

Please remember again that this is against Date dimension and also that Month and Year are two separate parameters (thus constituting two separate combo boxes and they are not multi-value).
