Setting A Null Value Through A Table Adaptor

Jan 31, 2008

(If this is not the right forum, please advise and I'll repost).
I am using Visual Web Developer 2005 Express (ASP .NET 2,0), with a SQL 2005 database.  I have programmed a Data Access Layer using table adaptors: this is my standard way of using the database. 

I had defined a table, Voyages: -
CREATE TABLE [dbo].[Voyages](
    [VOYid] [uniqueidentifier] NOT NULL CONSTRAINT [DF_Voyages_VOYid]  DEFAULT (newid()),
    [VOYUser] [varchar](50) NOT NULL,
    [VOYShipName] [varchar](255) NOT NULL,
    [VOYDepartPort] [uniqueidentifier] NOT NULL,
    [VOYDepartDate] [datetime] NULL,
    [VOYArrivePort] [uniqueidentifier] NOT NULL,
    [VOYArriveDate] [datetime] NULL,
    [VOYCaptain] [varchar](50) NULL,
    [VOYComment] [varchar](1024) NULL,
    [VOYUpdateid] [uniqueidentifier] NULL,
 CONSTRAINT [PK_RESVoyages] PRIMARY KEY CLUSTERED

I defined a table adaptor based on the query
SELECT     Voyages.*
FROM         Voyages
and defined variables in my VB code: -
    Dim tavoyages As New ShippingTableAdapters.VoyagesTableAdapter
    Dim tbvoyages As Shipping.VoyagesDataTable
    Dim trvoyages As Shipping.VoyagesRow

and read data into these variables with:-
            tbvoyages = tavoyages.GetDataByVoyid(Voyageid)
            If tbvoyages.Count > 0 Then
                trvoyages = tbvoyages(0)
                 ....
All of this works perfectly, and trvoyages contains all the correct data.
I wanted to set VOYUpdateID to NULL, so I coded 
    trvoyages.VOYUpdateid = Nothing
    tavoyages.update(trvoyages)
However this set the database field to "00000000-0000-0000-0000-000000000000", not to NULL.   However this code, in which we use another of the Update overloads naming all variables and "Nothing" in the VOYUpdateid position, works perfectly: -
tavoyages.Update(trvoyages.VOYid, trvoyages.VOYUser, trvoyages.VOYShipName, trvoyages.VOYDepartPort, trvoyages.VOYDepartDate, trvoyages.VOYArrivePort, trvoyages.VOYArriveDate,
                 trvoyages.VOYCaptain, trvoyages.VOYComment, Nothing, trvoyages.VOYid)
   
Is there any way in which trvoyates.VOYUpdateid can be set to Null.  I tried dbnull, but just got an error message.
Thank you,
Robert Barnes.

Setting Duplicate Fields To NULL

Mar 19, 2008



I have a result set stored in a temporary table variable. The fields need to have heirarchy when they finaly get displayed to the user. I need to replace the repeating fields per group with NULL and leave out only one set of unique records per group.

I want to do something like this- make the fields in red NULL while leaving out the ones in green.

{ Col.Group I } { Col. Group II }

Col1 Col2 Col3 Col4 Col5
------- ------- ------- ------- -------
ValA ValA2 ValA3 ValA40 ValA50 {
ValA ValA2 ValA3 ValA40 ValA50 Row. Group A
ValA ValA2 ValA3 ValA41 ValA51 }

ValB ValB2 ValB3 ValB40 ValA50 { Row. Group B
ValB ValB2 ValB3 ValB41 ValA51 }



I was able to achieve this by using @@ROWCOUNT with in a while loop by performing one UPDATE at a time (SET ROWCOUNT = 1). But i have to run Count(*) each time I loop through the update query to figure out the remaining number of rows I have per group as I need to leave out one untouched. But the Count function is taking too much time and I'm having performace issues.

Any idea how I might be able to do this in my stored proc. efficiently?

Thanks,

Setting A Date/time Field To Null

Mar 2, 2005

Hello!

I am using a Ms-Access DS which is accessed by a website's server-side scripts.

What I would like to do is set an existing record's date/time field to null. I have tried to simply alter its value by not including any data within the sharps (##), however that did not work.

How can I accomplish this?

Thank you!

Setting Empty Text Box Input On Form To Null Parameter For Sql

Feb 19, 2007

Hi,
 I'm pretty new to ASP.NET and VB, but I'm working on a project which is essentially a staff directory. Using VS 2005, I've setup a basic grid view which connects to an object which connects via a data layer to a SQL database with Name, Surname, Email, Extension No and Department fields.
I have it working so that if a user enters a name and surname for example, it will return all records with either the name matching or surname matching input parameters. What I want to do is to set up a SQL query which is:
 SELECT * FROM records WHERE (Name LIKE @Name) AND (Surname LIKE @Surname) AND (Email LIKE @Email) AND (Dept LIKE @Dept)
so that if the user only enters the first name and surname for example as above, it ONLY returns the record which matches the first name and surname and not all records with either/or. One way I've thought of to do this is to convert the empty fields to "Nothing" so that it fullfils the search parameter for the empty fields. If someone can explain how to do this, or can suggest a better way, I'd be grateful.
Cheers,
Tom

Problem With Isnull. Need To Substitute Null If A Var Is Null And Compare It To Null And Return True

Sep 20, 2006

Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you

set ansi_nulls off


go

declare

@inFileName VARCHAR (100),

@inFileSize INT,

@Id int,

@inlanguageid INT,

@inFileVersion VARCHAR (100),

@ExeState int

set @inFileName = 'A0006337.EXE'

set @inFileSize = 28796

set @Id= 1

set @inlanguageid =null

set @inFileVersion =NULL

set @ExeState =0

select Dr.StateID from table1 dR

where

DR.[FileName] = @inFileName

AND DR.FileSize =@inFileSize

AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)

AND DR.languageid = isnull(@inlanguageid,null)

AND DR.[ID]= @ID

)

go

set ansi_nulls on

How Do I Enter NULL In A Table Cell In The Enterprise Manager UI For Table Data Entry?

Sep 9, 2005

I have a column defined as smalldatetime. Default length (4), and "allow NULLS" is checked.In the Enterprise Manager UI, when i enter data into that table row, if i just tab past that column, all is well, and the value is represented in the UI as <NULL>.The problem comes once i ever enter a date into that column.  Say i have entered a date (all is well), and now i want to remove that entry and go back to NULL (after the date value has been committed, different entry session, say).How is that done?It seems to me, once a date has ever been entered into that column, now, if i try to remove it, i get the error "The value you entered is not consistant with the data type or length of the column, or over grid buffer limit".  I have tried deleting the value, entering spaces, entering the string NULL or the string <NULL>; maybe some other tries as well, but none works, i always get that error message and am not allowed to proceed past that cell until i restore a date value to it.  I want to get back to <NULL>.Anybody know?Thank you.Tom

What's The Accepted Way To Retrieve Records In A SQL Table With Null Values Using A Visual Studio 2005 Table Adapter?

Jan 21, 2008

I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database.
 I have a very simple dilemma.  In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields.
It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table.
In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters.
The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND   (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%')
If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null>
My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>.
For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null>  (accounting for about 95% of the records in the database). Thanks in advance Simon

SQL Server 2008 :: Non Blank / Non Null Value From Table To Update Same Table

Mar 13, 2015

Here is the sample data for table.

create table #sample (emp varchar(max),data1 varchar(max),data2 varchar(max), Rdate date)
insert into #sample (emp,data1,data2,rdate)
values('john','','',getdate())

insert into #sample (emp,data1,data2,rdate)
values('tony','','',getdate())

[Code] ...

I need to update the data1, data2 from yesterday or before but they should be non blank and non null and update to todays data.

It means, I can't update to 2015-03-12 values to 2015-03-13, as they are blanks or nulls.

So I need to go 2015-03-11 and check the values, if they are not blank , i need to update with todays values.

Before the update :

empdata1data2Rdate
john3/13/2015
tony3/13/2015
john3/12/2015
tony3/12/2015
johncd3/11/2015
tonyab3/11/2015

After the update:

empdata1data2Rdate
johncd3/13/2015
tonyab3/13/2015
john3/12/2015
tony3/12/2015
johncd3/11/2015

SqlDataSource SelectCommand - Dynamically Setting The Name Of The Table?

May 7, 2007

Can you dynamically set the name of the table in the SelectCommand section of the SqlDataSource? (If it is relevant, I code in C#)

<asp:SqlDataSource runat="server" ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:Test-MySQL %>" ProviderName="<%$ ConnectionStrings:Test-MySQL.ProviderName %>" SelectCommand="SELECT * FROM TestTable">
I would like to replace 'TestTable' with the name of a table that is extracted from a string array in the code-behind.

SQL 2012 :: Query Based On Column Name / Setting Up Database Table

Oct 30, 2015

I have a set of data spread across a number of tables regarding stock market data. An example of this follows:

Market Capitalization...

Date CompA CompB
01/01/11 100 5
02/01/11 102 4

Share Price....

Date CompA CompB
01/01/11 100 100
02/01/11 101 99

Event Data...

Date Company
01/01/11 CompA
02/01/11 CompB

Pretty simply, I need a way to retrieve the market capitalisation and share price data based on the event data. So for instance I say 'oh, there is an event on the 01/01/11 involving company A, the market capitalisation on this day was 100, then for the next event it was 4 for company B.

I can also transpose the data so that the company name is in the rows and the dates in the columns for the market cap and share price tables, but this leads to the issue that when I try and get the data, I don't know how to query the correct company for that date.

For instance:
SELECT Event.Date, Event.Company
FROM Event

how do I now say.....

SELECT MarketCapitalisation.Column
WHERE Column = Event.Company
AND MarketCapitalisation.Date = Event.Date.

I have played around with a few basic joins, but I am having issue with the principle of that second to last line of SQL (so only getting the correct column).

I still have a copy of the data in excel so can flip things around as needed, but that would only mean that I would have the issue of WHERE Column = Event.Date instead of Event.Company.

Built In Limit Or Setting That Limits The Number Of Rows From An OLE DB Source Table In A Data Flow Task?

Feb 16, 2007

I have a table that I'm loading as part of a control flow that in turn is copied to a target table by using a data flow task. I am doing this because a different set of fields may be used from the source entry to create the target entry based on a field in the source table. That same field may indicate that multiple entries need to be created in the target table from one source table entry for which I use a multi-cast transformation.

The problem I'm having is that no matter how many entries there are in the source table, the OLE DB Source during execution only shows 7,532 entries being taken from the source table. If there are less than 7,532 entries in the source table, everything processes fine. More than 7,532 and the data flow task only takes 7,532 and then seems to hang. It also seems as though only one path of the multi-cast transformation is taken when the conditional split directs a source entry down that path.

Seems like a strange problem I know, but any insight anyone could provide is appreciated. Thanks.

Alter Table Add Constraint Null Value

Lookup Table Foreign Key Null

May 1, 2007

I'm using SQL Server 2000. I have an EXTERNAL_FUNDING table and an EXTERNAL_FUNDING_TYPE table. The DDL for the tables is listed below. Each EXTERNAL_FUNDING record has a type field, which is a foreign key to a record in the EXTERNAL_FUNDING_TYPE table. However, I would like for the type to be allowed to be null. When displaying the data, if the type is null, I'd like to show blank text. Here is the query I'm trying to use:
SELECT EXTERNAL_FUNDING.id, date_requested as [Request Date],source as [Source/Sponsor],EXTERNAL_FUNDING_TYPE.type AS [Type],amount as [Amount], granted as [Granted]
FROM EXTERNAL_FUNDING,EXTERNAL_FUNDING_TYPE
WHERE (project_id = @project_id) AND
(EXTERNAL_FUNDING.type = EXTERNAL_FUNDING_TYPE.id)
ORDER BY date_requested ,source,type

But this query does not return the records with NULL for the type field. Can someone explain to me how I can also return the rows with a NULL type? Thanks!

Table DDL:
CREATE TABLE [dbo].[EXTERNAL_FUNDING] (
[id] [int] IDENTITY (1, 1) NOT NULL ,
[project_id] [int] NOT NULL ,
[date_requested] [datetime] NULL ,
[source] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[type] [int] NULL ,
[amount] [money] NULL ,
[granted] [bit] NULL ,
[date_granted] [datetime] NULL
) ON [PRIMARY]

CREATE TABLE [dbo].[EXTERNAL_FUNDING_TYPE] (
[type] [nvarchar] (30) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
[id] [int] IDENTITY (1, 1) NOT NULL
) ON [PRIMARY]

Cannot Set Numeric To Null Before Inserting To Table

Jun 21, 2007

Hi,



I have a flat file whose data looks like this:



"Opening Balance", Acct1234, 1001.01

"Closing Balance", Acct1234, 1001.01



In my script component for "Opening Balance", I set my output columns like this:



Row.AccountNumber = CDate(rowValues(1)

Row.OpeningBalance = CDec(rowValues(2))

Row.ClosingBalance = Nothing



Because I don't have a value for ClosingBalance in this row, I set ClosingBalance = Nothing.



And for "Closing Balance", I set my output columns like this, because there's no value for OpeningBalance.



Row.AccountNumber = CDate(rowValues(1)

Row.OpeningBalance = Nothing

Row.ClosingBalance = Nothing



Then, in my column mappings I map OpeningBalance = OpeningBalance and ClosingBalance = ClosingBalance.



The idea being that if there's no value, then it should be set to NULL. However, in my table, I see that instead of NULLs, there's 0.00000. Which is not what I want to see.



Any ideas why this is happening?



Thanks

CANNOT INSERT A NULL VALUE INTO TABLE RECORD

Apr 26, 2007

Hi all!

I'm runing an access application that has an sql server 2000 as its back end. Up to few weeks ago everything was fine, but now when a user tries to add a record from an access form into the database I get an error that it cannot insert a null value into the field.

The two fields that cause the problem do not allow nulls as they keep the user name and the time that the record was inserted into the table.

I trace the access program but I cannot pinpoint where the valuees are inserted into the table. All the other fields are bound on the form. When the problem first appeard I found out that at that same day the active directory server that keeps the logins to the network was restarded. The problem appears on the live database that the users use and as well as on my test sql server that is not connected to the main database server but is instaled on my pc together with the access application.

But I still have to login onto the same network to use my pc that is part of the same domain

The authentication on the sql server 2000 is windows only.



Any solutions or directions for this proplems?

Thanks for any help

Trigger Doesn't Log Into The Audit Table If The Column Of Table Has Trigger On Is Null

Jan 23, 2008



Hi,

I have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out

and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up

Any thoughts?


Here is my t-sql


Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)

select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d

where i.req_guid = d.req_guid

and i.req_fname <> d.req_fname



Thanks,
leo
