View 14 RepliesI am trying to have a query with the option for items to be null. (So users don't need to fill in the other fields if they choose not too) SELECT Tickets.TicketID, Tickets.UserID, Tickets.SystemID, Tickets.Title, Tickets.Description, Tickets.Software, Tickets.Date, Systems.OS, OS.OS AS OstitleFROM Tickets INNER JOIN Systems ON Tickets.SystemID = Systems.SystemID INNER JOIN OS ON Systems.OS = OS.osIDWHERE (Tickets.Title LIKE '%' + @title + '%') AND (Tickets.Software LIKE '%' + @software + '%') AND (Tickets.Description LIKE '%' + @descrip + '%') AND (Systems.OS = @osid) OR (@osid IS NULL)This works when i give the LIKE values % as a parameter. So they can choose to search by title + software but not description or description and nothing else etc etc etc. The problem is, the osid. If I give it a value it works but if i try to do null, *. or % it always displays every item in the databse ignoring any of the previous like statements. Anyone have an idea?
View 3 Replies View RelatedI have straight forward Insert Query, which takes values mainly from text boxes, however I am having trouble when the value is null.
eg
cmdP0.Parameters["@EmpID"].Value=txtEmpNo.Text;
When I run the Query I get...
Message="Parameterized Query '(@ID int,@EmpID int,@Photo nvarchar(260),@DoB smalldatetime,@Med' expects parameter @EmpID, which was not supplied."
I also get this when the parameter can be a string.
I have set the parameter properties so that SourceColumnNullMaping to true (it was set as false - so hoped this might fix it!)
No luck.

Hi
I am trying to view my reporting service web site for the first time,
but I've got this Error message "StringStartsWith can't accept null parameters"
I am using Widows Vista and
Report Manager and Report Server Web site has been set to Default web Site and
Windows Server Identity.BuiltIn Account has been set to Local System and
Web Service Identity.ReportServer and Report Manager has been set to Classic .Net App Pool.
Can anybody help me on this issue.
Best Regards
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

View 5 Replies View RelatedI 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.
I have two fields CourseID and Erpid in table.
CourseID has identity property with integer datatype.
I need to add a default value for Erpid column which will show a value like 'A' + CourseID column. Erpid is Varchar column.
How can I use Convert function in default constraint?
Thanks!
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. Diane

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

View 1 Replies View RelatedI am designing a new table with a few columns that may or may not havea value on each row that is inserted.What issues determine whether to allow a NULL value to be inserted forthat column or define a default value to be used?I want to think through the repercussions of this decision before I getinto production.
View 3 Replies View RelatedI 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?
hi,
I am using sql as a back-end server. My application requires to insert a default string values when the user do not provide any input or if the inpur is NULL. I have used the following code, but the defaul values are not inserted. I am not getting the desired result.
CREATE TABLE Employees1 (
EmployeeName varchar(50),
State char(3) NOT NULL DEFAULT 'NSW' ,
PostalCode int default 2000,
Country varchar(32) NOT NULL default 'Australia');
insert into Employees1 values ('diana', ' ' , 2,' ' )
The output is: EmployeeName State PostalCode Country

how can you alter a table so that you can add a default value whenever the field is NULL? for example, whenever the table is brought up in a query, NULL is replaced with UNKNOWN
View 1 Replies View RelatedHi,
What would be the Syntax in a SELECT statement to convert a Null Value to 0,
ie,
SELECT RowID, Amount FROM TableA
and Amount is a smallmoney field. For example it is coming back with:
RowID Amount
1 2.3000
2 15.0300
3 NULL
4 7.8900
But I want it to return:
RowID Amount
1 2.3000
2 15.0300
3 0.0000
4 7.8900
Thanks

I have to varchar columns that contain date and time columns.
Date Time
22-06-2015 12:28:29
My output that I want:
Date
2015-06-22 12:28:29
Is there a function that I can convert the date format like I want.
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.

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)
I want all the null (blank) values returned by a stored procedure to be shown as a string like "n/a", how to do that easily? Thanks

I am loading a flat file to a table but I also need to scrub the data a bit before the data hits the table. The main update required is converting a dot (.) character to a null value. The source file is using this character to indicate a blank. I know I can use the Dervived Column Transformation, but I have quite a few columns which will take a while to manually configure. Is there another transformation option that anyone can point me to?
Thanks
Hi
I've got a view which returns Null values due to an left outer join. The field which sometimes returns Nulls is called ClientCount. I want to create a new field which displays the value of ClientCount if ClientCount is not null and 0 if it is null.
In MS Access I use the following: IIF([ClientCount] Is Null,0,[ClientCount])
This does not seem to work in MS SQL. Is there some equivalent function I could use?
Thanks

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)
I have a stored procedure with a SELECT statement, that retrieves 1 row.
SELECT name FROM tblNames WHERE nameID = "1"
I want all the NULL values in that row to be change in some default values.
How do I do this?
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,
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

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.
I'm trying to have a default or null value in the dropdown list of the parameters on SSRS report. The dataset is bound with the Dynamics-AX 2009 AOT query. In the screen shot below you can see that I need a show All option in the dropdown list.
