DBNull Error

Apr 2, 2007

Am getting errors on this syntax:



Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)

Row.myColumn = DBNull.Value



Value of type 'System.DBNull' cannot be converted to type 'String'



Any ideas? Just want to set the myColumn to NULL.



Thanks

DBNULL Error - SQL Server2000/ASP.NET

Jul 20, 2005

Dear GroupI'm having a very weird problem. Any hints are greatly appreciated.I'm returning two values from a MS SQL Server 2000 stored procedure to myASP.NET Webapplication and store them in sessions.Like This:prm4 = cmd1.CreateParameterWith prm4..ParameterName = "@Sec_ProgUser_Gen"..SqlDbType = SqlDbType.VarChar..Size = 10..Direction = ParameterDirection.OutputEnd Withprm5 = cmd1.CreateParameterWith prm5..ParameterName = "@Sec_ProgUser_Key"..SqlDbType = SqlDbType.VarChar..Size = 10..Direction = ParameterDirection.OutputEnd With....cmd1.ExecuteNonQuery()....Session("Sec_ProgUser_Gen") = prm4.ValueSession("Sec_ProgUser_Key") = prm5.ValueBoth output parameters are declared as varchar(10) within the storedprocedure. If I run the stored procedure in SQL Analyzer, I'm getting astring value for each of them. E.g. @Sec_ProgUser_Gen is "1110011",@Sec_ProgUser_Key = "1100".Now the strange thing happens if I try to run the following code:Sub MyTest()Dim MyString1 As StringDim MyString2 As StringMyString1 = CStr(Session("Sec_ProgUser_Key"))....MyString2 = CStr(Session("Sec_ProgUser_Gen"))End SubIt fails in line 'MyString2 = CStr(Session("Sec_ProgUser_Gen"))' with Castfrom type 'DBNull' to type 'String' is not valid.I don't understand this. They are both the same, the only difference is thelength of the string. Help!Additional Information:The values for @Sec_ProgUser_XXX are created in the stored procedure with astatement like this:SET @Sec_ProgUser_Key = (SELECT Convert(varchar(1),Key_CanCreateKey) +Convert(varchar(1),Key_CanCreateTransaction) +Convert(varchar(1),Key_CanView) + Convert(varchar(1),Key_CanDelete) FROMi2b_proguser_securityprofile WHERE SecurityProfileID = @SecurityProfileID)The datatype of the source columns used to be bit then changed them toInteger as I thought this might cause the problem. (Although it shouldn't asthe values get converted to varchar without a problem in the storedprocedure. No fields contain NULL values, only 1 or 0.

Error 30311: Value Of Type 'System.DBNull' Cannot Be Converted To 'Date'

Apr 24, 2007

I'm creating an ISP for extractig data from a text file and put it in a database.

One of the fields in my textfile contains the value '0' or a date. If it's '0' it should be converted to the Null Value. The column in which it has to be saved is of type smalldatetime.



This is the code of my script where I want to check the value of the field in my textfile and convert it to a date or to Null.



Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)

If Row.cdDateIn = "" Or Row.cdDateIn= "0" Then

Row.cdDateInCorr = CDate(DBNull.Value)

ElseIf Row.cdDateIn_IsNull Then

Row.cdDateInCorr = CDate(DBNull.Value)

Else

Row.cdDateInCorr = CDate(Row.cdDateIn)

End If

End Sub



The error that I get is:

Validation error. Extract FinCD: Conversion of cdDateIn [753]: Eroor 30311: Value of type 'System.DBNull' cannot ben converted to 'Date'.



How do I resolve this problem ?

Getting Rid Of DBNull Values In DB

May 3, 2007

As a part of migration to .net we are redesigning sql server 7 database and moving it to sql server 2005. There are a lot of fields with dbnull value in the existing db. It would be nice to populate them with some default value while transfering data to the new datbase on sql server 2005.
What is the best way to deal with the issue, are there any possible drawbacks and problems.
Your input will be greatly appreciated.

Dealing With DBNull

Jan 10, 2008

Hello!
Is there an easy way to deal with this situation below when reading in data from a SQL Database:
int? myNullableColumn;myNullableColumn = Convert.ToInt32(datarow["datacolumn"]);
 
Where, ideally, 'myNullableColumn' would be 'null' if the value was 'DBNull.Value'.  This does not work because Convert.ToInt32 will not convert 'DBNull.Value to null', but instead throws an error.
Is there a built in funtion that does do this?
Thanks!

How To INSERT DBNull.Value's ? ...

Jan 26, 2004

Hello,

If I have a database table with column that can accept null values and I want to insert a null value into that column, what is the correct syntax?

db_cmd = New SqlCommand( "sp_stored_procedure", db_connection )
db_cmd.CommandType = CommandType.StoredProcedure
db_cmd.Parameters.Add( "@col_to_set_to_null", ??? )

ie: what expression can be used for "???"

Ideally, I want to check if a string value is empty and if so insert a null, but I have yet to see any examples, ie:

if ( str.empty ) then
insert DBNull.value into column
else
insert str into column
end if

Sincerely,

Brent D.

Does SQL Substitute Float = 0 With DBNull.Value?

Mar 11, 2004

Hi
I have only been coding in .Net for about six months, and am not sure if this is a C# problem or an SQL one. I use the Data Access Application Block in my program.

I have two optional fields on my form (RangeFrom and RangeTo). If the user chooses not to enter data into these textboxes(textbox = ""), an entry on the db is created with null values. It works.

But sometimes the user wants to enter 0 as either an upper or lower end of a range. This is where my problem comes in. My program saves 0 as null too.

In my program I do a test on the textboxes and populate two float values in a business object (objQuestion) accordingly, like this:


if (txtrangefrom.Text != "") {
objQuestion.RangeFrom=float.Parse(txtrangefrom.Text);
objQuestion.RangeTo=float.Parse(txtrangeto.Text);
}
else {
objQuestion.RangeFrom=Convert.ToSingle(null);
objQuestion.RangeTo=Convert.ToSingle(null);
}


And this is what my Business object look like. It sets up the parameters and calls the Data Access Application Block to create an entry in my table:


// fieldslist
float cvintRangeFrom;
float cvintRangeTo;

//properties
public float RangeFrom {
get {
return cvintRangeFrom;
}
set {
cvintRangeFrom = value;
}
}

public float RangeTo {
get {
return cvintRangeTo;
}
set {
cvintRangeTo = value;
}
}

// some code deleted for readability....

public int AddOption() {
string cvstrSpName = "addOption";
SqlParameter [] cvstrStoredParams = SqlHelperParameterCache.GetSpParameterSet(gcstrConnectionString, cvstrSpName, true);
//lines deleted for readability...
//check if the optional fields have a value associated with them. if not, assign dbnull.value.
cvstrStoredParams[4].Value=(cvintRangeFrom != Convert.ToSingle(null) ? cvintRangeFrom : (object)DBNull.Value);
cvstrStoredParams[5].Value=(cvintRangeTo != Convert.ToSingle(null) ? cvintRangeTo : (object)DBNull.Value);
//lines deleted for readability...
SqlHelper.ExecuteNonQuery(gcstrConnectionString, CommandType.StoredProcedure, cvstrSpName, cvstrStoredParams);
return(cvintOptionID = Convert.ToInt32(cvstrStoredParams[0].Value));
}


I use Convert.ToSingle when working with nulls (or possible nulls) because I get an error when I use float.parse for this.

The thing is, after this method AddOption has been executed, I test the value if the business object's rangefrom (that is where I entered 0) and display it on my form. I still shows a 0, but on my database table it is null!


objQuestion.AddOption();
//txtrangefrom.Text=""; on the next line I test the value in the business object...
txtrangefrom.Text=objQuestion.RangeFrom.ToString(); // and this displays 0!!!
//txtrangeto.Text="";
txtrangeto.Text=objQuestion.RangeTo.ToString();


So to me it seems the problem seems to be either the DAAB or on the SQL side, but hopefully somebody can prove me wrong! I was thinking that it could also be float.parse/Convert.ToSingle methods and have done various tests, but I am none the wiser...
Any help or ideas will be greatly appreciated...

Stupid DBNull Question

Jan 3, 2006

I haven't tested it, because at the moment I can't access my SQL database
I know this is probably a stupid question, but...How can I test for DBNull when I'm using SqlDataReader.Item(string)?
I use to check it using: if(!reader.IsDBNull(2)) ...But I have found that can not count on a particular ordinal reference because some of the stored procedures select the columns in different orders.
can I do something like: if(reader["Column1"] != DBNull.Value)or with the reader["Column1"] throw an error because it is not found??
I too hate when people ask questions that they could test themselves...but I can't really test it at the moment.  Any input would be greatly appreciated.

Datareader, DBNull And ?? Operator

Feb 5, 2006

Hi!
I was trying to use the ?? operator with an DBDatareader. eg:
long lValue = Convert.ToInt32(objReader["ParentID"] ?? -1);
which throws the following exception: "... Object cannot be cast from DBNull to other types."I think the reason is, that DBNull.Value isn´t actually null. Therefore I changed my code to:
long lValue = objReader["ParentID"] != DBNull.Value ? Convert.ToInt32(objReader["ParentID"]) : -1;
Is there a better way of doing this ? Can one use the ?? operator with a Datareader anyway?
Thanks for your help!
PS: sorry for my poor english.

Adding A New Column Is DBNULL

Jun 2, 2007

Hello,

VS 2005

I am developing the database application. This is a live database and is being used by the customer. I am to release a new version and I had to add new columns to fit the requirements DateStarted (DateTime), and TotalHours(Int) into a database table.There are already over a 1000 rows in this table.

When the customer wants to look at a record in this table and insert the value into the text boxes (Front-end), when it gets to the DateStarted or TotalHours it comes up with a error message:"

The value for column 'DateStarted' in table 'IncidentTask' is DBNull."The method for inserting is:



Code Snippet

Me.dtDateStarted.Value = Me.DsIncidentsControl.IncidentTask(0).DateStarted

What are the possible solutions to this problem? Would it mean checking for a DBNULL before displaying in the textboxes? Or updating the new column rows with an date:




Code Snippet

UPDATE IncidentTask SET DateStarted = '1/1/2005' WHERE (DateStarted IS NULL)

Many thanks for any suggestions,

Steve

Initialising Pbject Properties And Value Types To DBNull.Value

Aug 21, 2007

Hi,I have a ShoppingCart class with a lot of properties (due to structure of a legacy Orders table). I have a ShoppingCart table also which contains a lot of the same fields as my orders table.There are a lot of fields (mostly ints) which have been initalised to 0
in my ShoppingCart class and then inserted into the ShoppingCart table
when users add items to the cart. These fields are then inserted into the orders table upon check out.  When i attempt to place a new record in the orders table from the ShoppingCart table, I am receiving a bunch of Foregin Key constraint errors due to all the int fields containing 0's.What i would like to do is initalise all the properites of my ShoppingCart object to DBNull.Value but of course I can't convert type 'System.DBNull' to 'int' and i can't set to 'null' either as int's are value types.I also tried:private Int32 _fieldname = Convert.ToInt32(DBNull.Value);This compiled but gave InvalidCastException runtime error.So the only option that i can think of is, as i build the parameter array to be sent to my stored procedure, test the value of each parameter, if it is 0 (or an empty string) then don't pass the actual field value but pass DBNull.Value instead.I REALLY don't want to do this as there are around 60 parameters being passed to this procedure and this will be time consuming and messy.Any suggestions would be most appreciated!ps If i could avoid having 60 parameters being passed I would...trust me!

Stored Procedure Apparently Returning DBNull When It Isn't

Jan 22, 2008

 Hi,I have a stored procedure which returns an integer indicating whether the operation has succeeded or failed. It does this by calling set @returnvalue = (0 or 1) then select @returnvalue as returnvalue in the stored procedure code.  When I run the stored procedure, inputting a set of parameters as it expects, it does what it's supposed to do and outputs a table with a single row and a single column, called returnvalue, which has a value of either 1 or 0. When I run the stored procedure through a function in asp, using the exact same set of parameters, output the results as a data set and try and convert the return as an integer I get the following error: "Object Cannot be cast from DBNull from other types"The conversion code is ..return Convert.ToInt32(ds.Tables[0].Rows[0]["returnvalue"]);And if I change "returnvalue" to anything else (like "wibble" for example) then I get a different error telling me it can't find the column named "wibble". So the dataset definitely contains a table with a column in it called returnvalue, as you expect. But it's value is, apparently, DBNull instead of an integer.How come this works when called directly through SQL and fails when called through ASP? Can anyone help? This is really doing my head in!Cheers,Matt

Linq Question: Select Returns A DBNULL For An Integer Column

Feb 21, 2008

I have quite a few tables which allow NULL values. I have to struggle a lot with DBnull Exceptions :|example: col1,col2,... are all columns of type Integer and possibly NULL. var query =    from person in table    select new { person.col1, test = (int?) person.col2, person.col3, person.col4, ...};  As soon as my result encounters a DBNull value.. the whole query fails. This is really bad.How would I return the valid values.. and set the keys where there is no value to a null type? (e.g. int -> 0)I tried using "(int?)" but I'm not *really* sure what it does :-) Anyway.. it has no effect :-)

Unable To Cast Object Of Type 'System.DBNull' To Type 'System.Byte[]'.

Aug 13, 2007

Hi,
I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ?
Thanks a lot in advance.

You can ignore this and it will complete the installation, but subsequently trying to patch with SP2 will fail on the same sections - Hotfix.exe crashes whilst attempting to patch Database Services, Integration Services and Client Components (3 separate crashes).

I've removed SQL Server 2005 elements and tried to re-install, but it's not improved the situation.

Any ideas?

[XML Task] Error: An Error Occurred With The Following Error Message: There Are Multiple Root Elements.

Aug 18, 2006

I'm trying to use an XML Task to do a simple XSLT operation, but it fails with this error message:

[XML Task] Error: An error occurred with the following error message: "There are multiple root elements. Line 5, position 2.".

The source XML file validates fine and I've successfully used it as the XML Source in a data flow task to load some SQL Server tables. It has very few line breaks, so the first 5 lines are pretty long: almost 4000 characters, including 34 start-tags, 19 end-tags, and 2 empty element tags. Here's the very beginning of it:

<?xml version="1.0" encoding="UTF-8"?>
<ESDU releaselevel="2006-02" createdate="26 May 2006"><package id="1" title="_standard" shorttitle="_standard" filename="pk_stan" supplementdate="01/05/2005" supplementlevel="1"><abstract><![CDATA[This package contains the standard ESDU Series.]]></abstract>

There is only 1 ESDU root element and only 1 package element.

Of course, the XSLT stylesheet is also an XML document in its own right. I specify it directly in the XML Task:

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"/>

<xsl:template name="identity" match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>

<xsl:template match="kw">
<xsl:copy>
<xsl:apply-templates select="@*"/>
<xsl:attribute name="ihs_cats_seq" select="position()"/>
<xsl:apply-templates select="node()"/>
</xsl:copy>
</xsl:template>

</xsl:stylesheet>


Its 5th line is the first xsl:template element.

What is going on here? I do not see multiple root elements in either the XML document or the XSLT stylesheet.

Thanks!

I Have The Dreaded Internal Error Occured On The Report Server. See Error Log For More Details No Error Log

Apr 9, 2008

I have the error above, but no error log. I can preview the sub report - but this main report fails after working this morning. This is for internal company reports and I rebuilt this one after converting from access.
I have looked where the error logs should be, but there are no error logs.
I rebuilt the query as I needed to change this, but this did not help.
Is there someone who could point me in the correct direction.

Thanks!

Just Started Getting This Error When Trying To Connect To SQL From ASP.NET--error: 26 - Error Locating Server/Instance Specified

Apr 3, 2007

This has worked fine for weeks, and months.

I'm running Vista Ultimate. SQL 2005 is set as my Default instance, and SQL2000 is set as (local)SQL2000.

Today, actually half way through today, I restarted my computer after installing Photoshop Updates.

Upon getting my computer back up and running, I cannot access SQL2000 from any website on my computer, nor can I access it from SQL2005 Management Stdio. I CAN access it from Enterprise Manager (SQL2000 tool).

Whenever I run an web app that connects to it I get this error:


An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Now I usually get these when ASP.NET can't point to the right spot, but in this case I'm pointing exactly where I need to go. Any thoughts?

--Edit

I should also add my password got changed a few days ago on our Domain. This was the first time restarting after the PW change.

I got the following 2 errors.....

1.

Error : 806, Severity: 21, State: 1

For Error 2: I ran update statistics using query analyser. It is fine
Is there anything I have to do further?


For Error 1 : The work around given by Microsoft
=================================================
I ran
DBCC CHECKTABLE(syslogs)

I am getting the following message on :

All system databases and userdatabase recovered successfully when I restarted sqlserver.

Please advice how to get rid of this problem.


Thanks in advance,
Anu

The Push Method Returned One Or More Error Rows. See The Specified Error Table. [ Error Table Name = ]

Jan 10, 2008

Hi,
I have application in which i am performing synchronization between SQL Server 2000 and SQL Server 2005 CE.
I have one table "ItemMaster" in my database.There is no relationship with this table,it is standalone.I am updating its values from Windows Mobile Device.

I am performing below operations for that.
Step : 1 Pull To Mobile



Code BlockmoSqlCeRemoteDataAccess.Pull("ItemMaster", "SELECT * FROM ItemMaster", lsConnectString,RdaTrackOption.TrackingOn);





Step : 2 Using one device form i am updating table "ItemMaster" table's values.

Step : 3 Push From Mobile



Code BlockmoSqlCeRemoteDataAccess.Push("ItemMaster", msConnectString);




So i am getting an error on 3rd step.
While i am trying to push it says,
"The Push method returned one or more error rows. See the specified error table. [ Error table name = ]".
I have tried it in different ways but still i am getting this error.

Note : Synchronization is working fine.There is not issue with my IIS,SQL CE & SQL Server 2k.

Can any one help me?I am trying for that since last 3 days.

SSIS Error Code DTS_E_OLEDBERROR. An OLE DB Error Has Occurred. Error Code: 0x8000FFFF.

Jan 28, 2008

Hi All,

Recently in an SSIS package I am getting the following error for a particular Data flow task.





Error: 2008-01-25 12:01:48.58

Code: 0xC0202009

Source: Import Datasynapse Data User Events Source [3017]

Description: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x8000FFFF.

End Error

Error: 2008-01-25 12:01:48.73

Code: 0xC004701A

Source: Import Datasynapse Data DTS.Pipeline

Description: component "User Events Source" (3017) failed the pre-execute phase and returned error code 0xC0202009.

End Error

Our guess is when the data size of User Events table is more it throws this error. If we try to transfer small subset of data it succeeds. What could be reason for this error?

Since this is very urgent, immediate response would be very much appreciated.

Thanks & Regards,
Prakash Srinivasan

We are encounrtering a strange error in out sql error log:

This error occurs multiple times per day from several client stations.

It started when we enabled replication on that server, and started replicating the whole database to another server.
