) ================================================= In my VB 2005 Express, I created a project "KimmelCallNWspWithAdoNet" that had the following code: --Form_Kimmel.vb-- Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes
Public Class Form_Kimmel
Public Sub InsertCustomer()
Dim connectionString As String = "Integrated Security-SSPI;Persist Security Info=False;" + _
End Class ==============================================
I executed the Form_Kimmel.vb and I got no errors. But I did not get the new values insterted in the table "Custermers" of Northwind database. Please help and tell me what I did wrong and how to correct this problem.
Building the database I have come across different databases some that add a default value for every field and some that don't. I feel it is a hassle to add a default value, keep track if it is added. I guess with a default value there would be no "NULL" values in the database but one could also make sure in the C# code that all the fields have a value when inputed and on the way out check for nulls. What is the right way???? Pros and cons.........

Hi,I am trying to call a user defined function(UDF) from a stored proc,using a default parameter in the called UDF (e.g. @bid_price_type int= 0 ). However the calling stored proc complains that the UDF isexpecting a 2nd parameter when I only provide the @test parametervalue. Are default parameter values supported in UDF's?I wld really appreciate anybody's help. Thankyou in advance.UDF code:CREATE FUNCTION get_bid_price (@test int, @bid_price_type int = 0)RETURNS decimal(18, 4) ASBEGINdeclare @x decimal(18, 4)if (@bid_price_type = 0)beginselect @x = fieldNamefromtableNameendelsebeginselect @x = fieldName2fromtableName2endreturn @xEND' Calling Stored Proc codeCREATE PROCEDURE testASdeclare @x decimal(18, 4)set @x = dbo.get_bid_price(1)select @xGOthanks,Vic Y
How can I restore the original User Defined Function Template? I madean error and saved one of my UDFs as a template but would like theoriginal template restored?TIA
I have my stored procedure set to Territory_code IN (@Territory)
, now , how do i enter in more then one value. When i select the multi value check box, it gives me more spaces. But then doesnt recognize the values when i put in more then one. am i doing something wrong?
A have a multi-valued parameter (B) which is dependent on a single-valued parameter (A) on my report. When a value is selected in A, I want all matching values in B to be selected by default and the "Select All" option checked. To do this I have set the Default Values section in B to point to the same dataset as the "Available Values" section. Both A and B have default values so the report runs automatically.
One of the values in parameter A (say Value1) yields more values in parameter B than the other (say Value2).
If I run the report the first time with Value1 selected as the default for parameter A, all values in B are checked correctly. If I run the report with Value2 selected the first time and then change the selected value to Value2 and run my report, all values in B are displayed but only the values that were previously checked (when Value1 was selected), are now checked, leaving the "Select All" unchecked.
What am I doing wrong? Why are all the values in B not checked? The dataset is the same in "Available Values" section and "Default Values" section.
I have an example : A Simple Database Query using LINQ to SQL Before creating the project, I using SQLmetal to generate the Nosthwind Entity Classes "Northwind.cs" c:sqlmetal /namespace:nwind /code:Northwind.cs /pluralize /functions /sprocs /views "C:CongChinhNorthwindNorthwind.mdf" and then, I add the Northwind.cs in my project.

It throws a SQLExecption : Login failed for user ''. The user is not associated with a trusted SQL Server connection.I'm using SQLExpress and server name : CONGCHINHSQLEXPRESS and Windows Authentication I don't know how to solve this problem. Somebody help me,please !
I have inherited a database that has a column defined as bit. Looking at BOL it shows the valid values are 0,1, null. However there are several rows of data which have -1. Is BOL wrong? we think a VB program runs an update which changes this.

I need to set the default value of a field in my table to 'Regular' if nothing is inserted to that field. Is it not as easy as putting ('Regular') in Default Value?
We have a table that needs to have 00 as the default values in the columns until the point in time where they are updated with the values that we will use. The updated values will be two numbers 1-7 and 3-9 example 47, 14, 26, 68. This is a nvarchar data type in the columns. When I try to set the default values to double zero 00, after i click save it changes them to a single zero 0 instead of a double zero 00.

How do I insert/add a default value in if the query above generates zero result?
I have a row of data being inserted in to a db table with default values, say: Name Date1 Date2 and I'm inserting VALUES 'myName','12/04/83',NULL Is there any way for the field Date2 to take the value being inserted into Date1 (ideally via default value)? (Any good database tutorials would be handy! Thanks)
Does anyone know if or how I can insert a default value of the (+) character into a column? when I try to save it I get an error message saying it has a problem with ')'.
I have a DTS package that is connected to a table in an Access97 database and to a duplicate(by schema) table in SQL2000. If there is a default value in the Access97 field properties the DTS package will import that value regardless of any other value in the Access field. I can not see anything in the DTS designer that handles this choice.
Even when I look at the Access connection in preview it shows only the default values.
The columns fro which we do not enter any values.Fro eg in my table i did not insert any values to Balance col,in my table. In SQL 2005,management studio,when i said modify table and changed the default to 0 from NULL and also unchecked the checkbox saying Allow Nulls.
I did the above changes and said save.It gave an error saying
'AccountsBalance' table - Unable to modify table. Cannot insert the value NULL into column 'Balance', table 'AccountBalanceSheet.dbo.Tmp_AccountsBalance'; column does not allow nulls. INSERT fails. The statement has been terminated.
How can i change the default value of a column? I already have a columnnamed DateOfRental but I want to alter it so that it has default valuegetdate()ThanksDavid--http://www.nintendo-europe.com/NOE/...=l&a=Prodigious
Pardon the newbie question...but I'm trying to load a dimension table in a small data mart that has columns in it that are unique to the dimension and not sourced from any source table. Two of those columns are date columns that I want to default to the system date and the other column I want to load with a default value. I can't figure out how to do this within a data flow task. The source columns flow from the input db source into a scd transform but I can't seem to edit the columns in the target table table if they don't actually come from a data source. There doesn't seem to be a data transform object to handle this.
I have a report that I run where the selected MONTH and YEAR defaults to the prior month and year. When I run the report it shows the parameter values show as June 2007. Which is correct since this is July.
If I schedule the report to run on the 1st of every month will it default to the prior month/year automatically (I have the "use default" box checked).
I have a this SP that inserts values into a table with results from a query, but at the same time I want to insert some default values.But thats NOT working the way I hoped for, actually sqlserver 2005 dont let me create this SP at all."Incorrect syntax near the keyword 'DEFAULT'."Can someone please tell me how I can achieve this? create procedure %PROC% ( @Ordre_ID int ) asbeginIF NOT EXISTS(SELECT Ordre_ID FROM tbl_Ordre WHERE Ordre_ID = @Ordre_ID AND Ordrestatus IN ('2', '3', '4'))BEGIN return 0;ENDIF EXISTS(SELECT Ordre_ID FROM tbl_Faktura WHERE Ordre_ID = @Ordre_ID)BEGIN return 0; ENDBEGIN TRANSACTIONINSERT INTO tbl_Faktura( Ordre_ID ,PostNummer ,KID ,Fakturastatus ,Kontonummer ,Forfallsdato ,Belop ,BekreftetBetaltDato ,Faktura_GUID ,Adresse ,PostBoks ,Fornavn ,Etternavn ) (SELECT O.Ordre_ID ,K.PostNummer ,DEFAULT ,DEFAULT ,SI.Kontonummer ,(getdate()+14) ,v_OTS.TOTALBELOP ,DEFAULT ,DEFAULT ,K.Adresse ,K.PostBoks ,K.Fornavn ,K.Etternavn FROM tbl_Ordre AS O INNER JOIN tbl_Kunde AS K ON O.Kunde_ID = K.Kunde_ID INNER JOIN v_OrdreTotalSum AS v_OTS ON O.Ordre_ID = v_OTS.Ordre_ID ,tbl_StatiskeInnstillinger AS SI WHERE O.Ordre_ID = @Ordre_ID ) UPDATE tbl_Ordre SET Ordrestatus = '6' WHERE Ordre_ID = @Ordre_ID COMMIT end go
Hi, I have something similar to the following: CREATE PROCEDURE dbo.MySproc @columnVal int = nullASBEGIN SELECT * FROM MyTable WHERE MyTable.column = @columnVal END If columnVal is not passed into the stored proc i want it to just select everything from 'MyTable' (without the WHERE clause)....how can I do this in as few lines of code possible?thanks
Hi, all, does anyone know of a way to change default values inside of a table without affecting existing values?
I have a table with default = 0 in usermask column. Some rows already have non 0 values in them. I now need to change the default to 1 but still want the non 0 values be there. I also want the new default to take effect when new rows are entered. What's the best and quickest way to do it?
In my datawarehouse fact table I have a column (revenue) that I want to populate based on the values of number of columns, for simplicity, say just 2 columns, 'productid' and 'affiliateid'.
I have a revenue lookup table, with those same 2 columns and the amount. So far so simple, but rather than have one row for every possible combination, I use 0 to mean default. For instance, all the affiliates have the same revenue value apart from a couple, so instead of 200 rows identical except for the affiliateid, I have one row with a '0' for the affiliateid and 4 rows with specific affiliateIDs where it differs from the default.
To update the values, I join to the revenues table twice, one for both columns matching, and once for the default. I.E.
UPDATE facttable SET revenue = ISNULL(rev1.revenue, ISNULL(rev2.revenue,0)) FROM facttable FT LEFT OUTER JOIN revenues rev1 ON FT.AffiliateID = rev1.AffilateID and FT.TypeID = rev1.TypeID LEFT OUTER JOIN revenues rev2 ON rev1.AffilateID = 0 and FT.TypeID = rev1.TypeID (In fact, this is over-simplified, because in fact there are 3 columns, so I have to have 8 joins like this).
This works very well, and cuts down the management of revenues significantly, there are a few 100 rows instead of the more than 100,000 there would be if I put every possible combination of values in its own row.
However, now there is a requirement to increase the granularity of the revenue allocation up to 5 columns, which makes 36 joins and there could well be more columns added later.
Has anyone come across a situation like this (and found a neater solution).
