May 14, 2010
I have trouble of saving "no time" to a datetime field in my db by using objectdatasource.I am using a formview to insert new record by an insert method in an objectdatasource.
how do i insert date and time together ? what is the format for this. i tried like this but its not working.
string startDtime = TextFromDate.Text + " " + Stime; sql_comm.Parameters.AddWithValue("@StartDate", DateTime.Parse(startDtime)); is this the right way ? dd/mm/yyy +" "+ 00:00 or i need to make a string that contain this : dd/mm/yyy00:00 its not writing any eror it just do nothing .

This is the sqlDateTime overflow problem again. Background. As I'm sure you know dates must be between 1/1/1753 and 12/31/2999. If you have an empty date field, it throws and exception. So I created a function (below) that solve the problem when attempting to update or insert a record with a date field. Works great.
Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of DateTime)
If IsDate(pasDate) Then Try If pasDate <= System.DateTime.MinValue Then Return Nothing Else Return CType(pasDate, DateTime) End If Catch ex As NullReferenceException Return Nothing End Try Else Return Nothing End If End Function
So I thought about using a time field. I have the field, have the validator in place and then attempted to test the page. It resulted in my least favorite error message "sqlDateTime overflow".
I can think of several workarounds like adding a date or a fixed date to the time field, or converting it to a string. Each of these is problematic.
IS THERE A BETTER WAY TO UPDATE/INSERT TIME FIELDS.
I'm looping through an ArrayList and creating a column in a DataTable from each field. One of my fields is a DateTime field, and I've noticed that when I create the columns, it's being changed to a String, but I need it to still be a DateTime field for sorting. I'm trying to do this, but it's not quite working.
I am selecting time from dropdownlist. and want to convert it in datetime and store it in database. When I am converting it to Datetime using following statement.
I have a gridview with two textboxes (first name & last name) and a linkbutton to search results inside the gridview.
I have made select parameters as well and the search works if i write in both textboxes. However, if I leave one textbox blank, i don't get any results.
[code]...
How can I get results from searching only one textbox?
I have a form and stored procedure that inserts the data from the form. It works fine except that if a field isn't filled in it doesn't insert a NULL into sql it inserts "".
I've tried a few different ways but none seem to insert NULL, the one below still inserts "", can anyone point me in the right direction.
Here is the required part of the code, if you require more just let me know.

So if I enter nothing into address1 field it should write NULL to screen but it always writes NOT NULL.
For example: INSERT INTO table (col1, col2, col3) VALUES ('value1','value2,'value3')But I would only like to insert the row if value3 isnt already present in col3 in some previous row. What is the best way to do that?And the insert command is run 50+ times in a loop (with different values each time for value3)
My database includes a table with sever filds which are defined as (varchar(1),null), I tried using DBNull.Value, null, ' ' but cannot get a null inserted in that field of the database,
I have a table in SQL where I insert data (CatCodes) using C# code but I want to insert ID code (DealerID) with it as well. Following is my Stored Procedure and C# code:
[Code]....
C#:
[Code]....
As you can see, I am insering CatCode values in Categories table using string cbspecialities.
How can I insert DealerID the same way? DealerID is automatically generated in tblDealers table when "InsertExternalInfo" asp.SqlDataSource control runs "InfoInsert" SP.
Is there a way to create a contact form that takes the name. address and other info for the master record; Then, somehow, on the same page, allow the user to enter multiple contact info as chid records (i.e. phone, email, etc.)
All this using the Objec DataSource or SQL DataSource (which ever is easy) and doesn't require writing too much code.
I have a insert into statement thats inserting my numbers from a numeric text box on my aspx page. I am choosing the Amount Type then putting in a a number.
So i have a drop down that i select example Direct Charge then i enter 600.00 and click add it puts that in to the databse for me woot..
I then put in say Misc Credit and enter 200.00 it inserts in that into the database woot.
The look up table that has my amount types has a field called numeric opperator which is either + or - the Credit being a - and the Charge being a + then my stored procedure takes all my + numbers and adds them up and subtracts all the - numbers.
I want to change that so that it actuall be inserted into the table as a - number form the start. So I want choose Misc Credit enter 200.00 and click add then my event says o yea thats a credit insert 200.00 as -200.00
