ADO.NET :: Setting The DefaultValue Of A Datetime Column In A TableAdapter?
Feb 9, 2011
I have an SQL table with a smalldatetime column. The Default Value is set to (getdate()), as I want it to insert the date in which the record is inserted. Null values are not allowed.In my corresponding Table Adapter in Visual Studio 2010, when I select that column and view Properties, under DefaultValue it has <DBNull>. If I try to change this to GetDate(), it won't let me.What's the proper way to do this?I am getting the Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.error when I try to execute a Table Adapter query that simply tries to return all the rows.
I use AjaxCalendarExtendar in web form. my code is below: clsDest.ADate = DateTime.Parse(txtADate.Text).Date;
Here 'ADate' field is also a DateTime type. In 'A' laptop, DateTime saving is correct format. In this laptop, Regional and Language Current format is English (United States) - M/d/yyyy. When I save this ADate at another laptop 'B'. DateTime format is wrongly saved. Firstly, this laptop's regional setting is English(Singapore). So I change it to English(United States) but still wrongly saved. Here, the other datetime field, UDate is saved by DateTime.Now. This field's Datetime format is not changed.
Before saving with M/d/yyyy ADate - 01/08/2010 UDate - 01/25/2010 After saving ADate - 08/01/2010 UDate - 01/25/2010
I have an entitydatasoruce that is driving a gridview. I have a WHERE parameter that i want to include 2 default values (example Work_Area = 1 OR 2)But it seems I can not input this query when making a querystring within the expression editor
note MONTH AND DATES stored in single or double digits as they occur. Unfortunately DATE TIME is stored in NVARCHAR Data type column as 2/9/2010, 22/10/2010 etc. Following UK Date here. It is required to pull the data to COUNT No. of Expired. Obviously below one fails.
I'm loading data from my database into a DataTable, and one of the columns is a date field.
[Code]....
I'd like to format that column so that instead of containing a full date, it will be formatted like "MM/DD/YYYY".
I've tried looping through each row in the table and changing the cell for that column, but I get an error saying that the string isn't a valid DateTime object.
I tried changing the column DateType to a string, but I get an error saying I can't change the DateType after the table is filled.
How can I do this? This seems like such a simple thing, but I'm having so much trouble with it.
While debugging my Javascript, I've noticed that ComboBoxes always have an empty string as their defaultValue (as opposed to the actual original value). This is making it impossible to write even a semi-reliable client side script to check if a form has been filled out and warn the user if they attempt to navigate to another page or close the window.
I'm working with Linq and I'm using with ObjectDataSource that have SelectParameters tag for inserting default parameters to object.
How can I set <DefaultValue> for an array parameter ?? (i.e : object that have 2 parameters - string and array of int , I can set <DefaultValue> for the string but I don't know how to do it for array)
I em trying the change the values of all numbers to o in a column calld QuP in a table called Segments with no positive results. The same query works ok testing in SQL
Dim sSql0 As String = "update Segments set QuP = 0" Dim oconn As SqlConnection Dim ocmd As SqlCommand try oconn = New SqlConnection(oseriDB.GetConnectionString) ' the connection string is working right ocmd = New SqlCommand(sSql0, oconn) oconn.Open() oconn.Close() oconn = nothing Catch ex As Exception lblmsg.Text = ex.Message End try
I want to set the coulms size of all the columns in the table in the DB based on the maximum width/size of one of those columns of that particular table That is if I have three columns Name(nvarchar 50), Address(nvarchar 70) and Description(nvarchar 100), then I want Name and Address to also be nvarchar 100, can anyone give me the code for the same in VB.
Am I going to be able to query (using LINQ to SQL) a database field with a type like the following "public System.Nullable<System.DateTime> Spouse_DOB"?
I'm trying to use the following code: [Code]....
and I get the error "'System.Nullable<System.DateTime>' does not contain a definition for 'Month' and no extension method 'Month' accepting a first argument of type 'System.Nullable<System.DateTime>' could be found (are you missing a using directive or an assembly reference?)"
Is it because this DateTime column allows a NULL value (since everyone isn't married in my database)?
Error 1 'System.Nullable<System.DateTime>' does not contain a definition for 'Month' and no extension method 'Month' accepting a first argument of type 'System.Nullable<System.DateTime>' could be found (are you missing a using directive or an assembly reference?)

How do I select a column with the latest "datetime" data type, in Visual Web Developer 2008, ASP.NET 3.5 ?
In the config data source WHERE option my options are greater than cookie, control, etc... but I would like to select where the datetime is the latest in the table.
I an expanding on the HotGridView control (http://msdn.microsoft.com/en-us/magazine/cc163612.aspx). During testing I noticed the "AutoGenerateCheckBoxColumn" behavior was returning true even if the user did not specify the a value in the markup but I expect it to return False if not value is supplied by the user - can anyone shed some light on why the AutoGenerateCheckBoxColumn is always true if not explicitly set to False in the markup?
what I am trying to do is add a method to my gridview's sorting event to add a class to the column being sorted so the user can know if the data is being sorted ascending or descending and on what column. I am currently trying to do it through a switch statement on the sort expression to determine what column it's coming from but I am unaware of how to set the css class.
I have sutmbled across somethig strange. When you ser theYou cannot set the color in a style and apply it to the heading of a grid, it will show in the templated columns, but not in the non-templated columns.
You can set the color for the non-templated columns with the HeaderStyle-ForeColor attribute, but it seems strange for it not to recognize the color in the style and seems redundant to have to specify a style and a color seperately.
Am I doing somethign wrong. Is there some sort of setting I have wrong that is causing this?
I added a DateTime column to a table in my database through the Server Explorer. Because the team lead for this project wasn't savvy on nullable types, one of the requirements was that there be no null values in the database. This requires me to program all sorts of useless code into the system, but that's another story. My problem arises when assigning a default value to this column. I typed the following into the cell for the "Default Value or Binding":
1/1/1753 12:00:00 AM
When I went to inspect the content of the table, I found that all of the dates had been populated with:
