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

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 :-)

Adding Column To A Table Before An Existing Column

Mar 30, 2004

I simply need the ability using SQL to add columns in an existing table before (or after) columns that already exist.

The MS SQL implementation of ALTER TABLE doesn't seem to provide the before or after placement criteria I require. How is this done in MS SQL using SQL or is there a stored procedure I can use?

Thanks.

Adding A Time Column To A Date Column

Jul 20, 2005

I have two columns in a table:StartDate DateTime and StartTime DateTime.The StartDate column holds a value such as 07/16/2004The StartTime column holds a value such as 3:00:00 PMI want to be able to add them in a stored procedure.When I use StartDate + StartTime I get a date two days earlier than expected.For example, instead of 7/16/2004 3:00:00 PM StartDate + StartTime returns7/14/2004 3:00:00 PM.Can anyone point out wht I'm doing wrong with this one?Thanks,lq

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.

Adding New Column

May 5, 2008

Hi,I have an application up and running. I need to add a new column to one of the tables which is currently being used - would adding a new column change or cause errors in the current application? e.g. if the table is being accessed by selecting * from table, will adding a new column cause an error? If there is any circumstance where an error would be caused by adding a new column, I will have to create an entirely new table. If I have to do this - how do I get a column in the new table to have the same values as a column in the old table? Can I create a computed column where column=oldcolumn? Thanks,Jon

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 isnĀ“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.

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.

Adding A Column To A Table

Feb 24, 2003

Can I add a column to a database table without dropping and recreating the table?

The problem is that everytime a user creates an action that requires a new table - at the moment I drop the table and recreate the table with the new column.

This requires lots of resources as I have to populate the table again.

Is there a design way I can go around this?

Adding A BIT Column - 100+ Hours!

Jul 7, 2004

I previously posted about a problem where I added a non-NULL DEFAULT 0 bit column to a table with 80 million records. It was taking a LONG time and we needed that database up fast. It ended up taking a total of 17 hours.

Now my coworker added the same non-NULL DEFAULT 0 bit column to another table on another important server. But this table has more like 400 million rows. It's been running for 100+ hours and is still going. We were hoping it would scale linearly (5*80 million records would hopefully take 5*17 hours) but that isn't happening. I have no idea how much longer it will take. I really need this to be done. I'm tempted to cancel but that will incur a potentially massive rollback, right? Any guestimate on how large that would be?

Any ideas?

Adding A Column Then Using It In A Script

Jan 20, 2004

Hi,
I would like to alter a table in a sql server database then update the column with data in the same script. However, the database does not recognize the database column if I create it within the script. Is there a way to refresh this within the script so that I can run this in one procedure? If I create the table in one script then update in a second script it will work. Thanks.

Adding A SUM Column To Query

Oct 29, 2013

I have a pretty simple SQL query that has two columns that contains only numbers. Is there a way i can add an extra column that simply subtracts the number in one column from number in the other column.I query the data tables rather than have a live link so the .csv file gets overwritten every time i run the query.
