Does anyone have a simple way of inserting a NULL value into sql 2000 datetime. I'm using vb.net.
All I want is if the user does not enter a date in a textbox to to send a NULL value to the DB instead of having the db enter the default value as 1/1/1900.
Thank you
Hi,
If a datetime variable is empty I want to insert null into the database table.
How do i do this? Below code doesn't work. Get this error...
Cannot implicitly convert type 'System.DBNull' to 'System.DateTime'
Code Block
if (myDataGridView.Rows[iRow].Cells["myDateDataGridViewTextBoxColumn"].Value.ToString() != "")
{
myDateReport = DateTime.Parse(myDataGridView.Rows[iRow].Cells["myDateDataGridViewTextBoxColumn"].Value.ToString());
}
else
{
myDateReport = DBNull.Value;
}
Hi I'm using DetailView and I have a text box which show the date. I have formated the date as shortDate {0:d} format. I want to insert/update null if that text box is empty.
I have tried putting null value in my Update statement in sqlDataSource. And I'm getting error saying can't convert varchar to smalldatetime.
If I don't set null value as above, some large date (01/01/2033) has been inserted in my database.
Can anyone help me?

I'm importing data form an Excel file to a Sql Server Database. Some of the data imported represents time as a double type so i convert the times into DateTime to be inserted into the database. The time values that aren't available in the Excel file are 0.. so what i want to do is insert null into the database for all the values that are 0 in the excel file...

View 3 Replies View RelatedI have a table adapter for one of my SQL2005 tables, and in two different fields I accept a date time. Now 99% of the times, new rows to this table will be filled out using DateTIme.Now(), as a Time Stamp is what I'm going for.
Here is the line of code in question...cops_current_data_adapter.Insert(ProductOrder, Convert.ToInt16(Session["StationId"].ToString()),
PartNumber, DateTime.Now, DateTime.Now, Convert.ToInt16(qty), 0);
The second DateTime.Now is the one that can be null, and it's throwing a formatting error everytime I try and drop it in there. It's a FormatException, and there's not much more to the example except unhelpful tips like be careful when conveting a string to a dateTime, which I'm not doing. Needless to say for the code to compile, and then throw a Format error at runtime is a bit frustraiting.
Any suggestions would be most appreciated
I have a flat file with the following columns
SampleID  Rep_Number  Product  Protein  Fat  Solids
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.

Hi,
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 (to have the calendar control for selecting date) for which I enabled NULL value. The result is that next to this parameter there is a checkbox "NULL" which allows to send NULL as a value of this parameter. Everything is fine except for the prompt: "NULL"... Is there a way to change it? I would see there something like "Empty" or "Not selected", which would be understandable for users of the report.
Or is there any other way to send an empty date as a value of this parameter? (Setting some unusual value like 1/1/1900 for empty date is not sufficient as the empty value shouldn't appear in the parameter control).
Thank you,
Michal
Hi All,
I have a problem while trying to set "NULL" value to my datetime parameters.
I have two datetime parameters (AllowNull=True) on my report. (BeginDate and EndDate)
it works fine in preview mode in reporting design.
The problem occurs, if I try to set an emtpy value to these parameters in my asp.net application.
The code looks like;
Dim repParams(1) As ReportParameter
repParams(0) = New ReportParameter("BeginDate", String.Empty)
repParams(1) = New ReportParameter("EndDate", String.Empty)
-----
ReportParameter method requires String parameters. If user set any datetime value, I am sending "String.Empty" value to my paramaters in order to set them as NULL. But I am getting "rsReportParameterTypeMismatch Error."
How Can I set NULL value to these parameters from asp.net application?
Thans alot in advance.
I have a datetime field in a database which I am programmatically inserting values into. The field can be null or not null. However, I am having problems inserting NULL as part of my SQLCommand.
The value is pulled from a text box (linked to a calendar extender) and when I select a value it is being inserted fine. If I just leave the box blank though, I want the field to be set to NULL. I have tried adding in ,DBNULL.Value, as part of my VALUES(…) string, but this throws an exception. I Have tried just inserting ‘’ but that also throws an exception (“The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value�), so I don’t know how I can insert this value when the field is blank?
Can anyone shed some light please? Thanks

Ive created a Data Access Layer (xsd file) and some of the tables have DateTime columns. I need to allow NULL values to be saved, but when I try to do that I get an error
In my code (c#) ive used Nullable DateTime, but when I try to assign a nullable Datetime to a DateTime column, I get this error
cannot implicitly convert type 'System.DateTime?' to 'System.DateTime'
I understand the reasons why, so how do I save null DateTime values to the underlying database through a schema ?
In the schema file, the DateTime columns have <DBNULL> as the default value, AllowBDNull is true, but I am only allowed 'Throw exception' on the NULL value property
I could probably do this another way (by not using a schema and writing the code myself) but Id prefer to keep the strongly typed code.
I dont want to use MAx or MIn values for the default datetime values, so how can this be done ?

Hi. I wrote a sproc to insert values from a tab-delimited text file into SQL 2005. There is a column in the text file that contains datetime values. Some of the values may be null.

View 3 Replies View RelatedHi there ;
This Problem is goin to make me crazy!
I've got a table with couple of fields, 2 of them are DateTime, in Sql Express 05 .
I used asp.net 2.0 to insert datetime values, directly, using sth like DateTime.Now.ToString() .
i use 2 selects as follows :
1)select * from X where Date1='8/9/2006 11:17:41 AM'
2)select * from X where Date2='8/9/2006 11:17:41 AM'
#1 is OK, but the second one returns a row with all columns set to NULL .
(X is the name of the table)
Thanks in advance
Hi,I have a table adapter that I am using to call a stored procedure on a SQL server database to insert a record.Everything works ok, except I cannot figure out how to pass a null value to a DateTime field. In my SQL server database, the column allow nulls. In my typed dataset, the column is set to allow nulls.When I try to run the insert procedure with a null value: ListTableAdapter da = new ListTableAdapter();
da.InsertList(System.Data.SqlTypes.SqlDateTime.Null, Name); I get this error: Error 14 Argument '1': cannot convert from 'System.Data.SqlTypes.SqlDateTime' to 'System.DateTime?I've also tried passing it DBNull.Value, but I get an exception with that too.Can anyone steer me in the right direction with this?
If myDateTimeColumn contains a <NULL> value. How do you handle that when reading into a DateTime object in your code?DateTime myDate = Convert.ToDateTime(dr["myDateTimeColumn"]);Does not work, it throws: System.InvalidCastException: Object cannot be cast from DBNull to other types.
I am curious as to what others are doing to handle this?
Hi,
When I try to insert a new record into a table that has a datetime field that allows nulls, a default 01/01/1900 date is inserted instead of null. I recreated the table and set the datatype to smalldatetime and I still get the error. What have I missed?
In a VB.NET script, I am adding the dbnull value to a parameter that will populate a smalldatetime column:
cmd.Parameters.Add("@unitHdApprove", System.DBNull.Value.ToString)
The stored procedure then defines the input as smalldatetime:
@unitHdApprove smalldatetime,
However, the result is that the record is inserted with 1/1/1900 as the date value, instead of <NULL>.
I'm guessing that this occurs because the conversion of a '' to date will return 1/1/1900, and VB requries the parameter value to be a string (at least with this syntax), so System.DBNull.Value.ToString really equals ''.
I've rewritten the proc to accept the date as a string instead, and then for each date, cast it to a smalldatetime or set it to null as is appropriate. But this is a really bulky way to do things with more than a few dates! Is there any way to change what is in my VB code so that the procedure will insert the actual null value?
Thanks,
Sarah
Hi,
I have a flat file source and am bringing it into an OLE DB Destination connected to a SQL Server 2005 database. Since I am bringing in the data via a flat file, I have a conversion step in the data flow, which uses a "Data Conversion" transformation to convert each column to the appropriate destination data type.
When I run my SSIS package, if the datetime column in the flatfile is NULL, then the Data Conversion step fails. I have my Data COnversion step set to redirect error rows to an error output. So, I get all the rows with populated datetime values in the intended destination, and none of the rows with null datetime values (these go to the error destination.)
This is a problem! I need to make sure all valid rows fall through. It seems very odd to me that a NULL datetime could not be converted to a datetime data type. This makes no sense, since a datetime column can naturally hold NULL, just like any other type. So, my question is: is this a bug??? It seems to me it is. I can't believe this would be the desired behavior?!
Microsoft: please let us know whether this is expected behavior. If so, then what would the desired workaround be?
Thanks

I get no records, but i can see and know i have hundreds! I know i'm doing somthing really stupid, but for life of me can't figure it out! :eek:

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". Â
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.
There was a similar question to mine a few time ago about conditional execution, but I'm having some problems with it to which I couldn't find any answer, could anyone help?
My condition is checking if a DateTime from a DB table is null. I use the Execute SQL Task to retrieve the record (SELECT TOP 1 * FROM myTable WHERE conditions = TRUE), then I map 2 fields to their respective global variables.
Then I created the green arrow connector and used a precedence expression based on sucess. I used the expression IsNull(@variable). For some reason, even if the @variable comes as null - I checked the info in the DB - it still comes out as '1999-11-30'
I've looked around and the IsNull method can be used to also change the value in the event of it being null, could it be changing my variables value to this even if I didn't pass that value as a parameter to the function? If so, how else can I test it for null? I've tried "== null", "= null" and even ".equals(null)" - which I know is absurd, but I'm running out of options here...
Could you enlighten me, please???
Thanks in advance!
Hello,I've been searching the web for quite some time to resolve the problemof "1/1/1900" returning in a datetime field in SQL that resulted from ablank (not NULL) value being passed to it through an ASP page.The solution is that a NULL value needs to passed to SQL from ASP.Thats fine...I understand the why the problem is happening and thesolution around it. HOWEVER, I can't seem to get the proper syntax towork in the ASP page. It seems no matter what I try the "1/1/1900"still results.
