convert below datetime value which is as varchar datatype to another datetimeformat as varcharchar datatype
2010-05-19T13:05:08.6Z
I have been looking for a way to convert C# datatype into database specific type of MS SQL. For example when I do [Code]....
I would get System.GUID or something like that but what I want is UniqueIdentifier instead of System.GUID. In most cases, I would also want the length of the type like varchar(1000) and stuff like that. Is there anyway I could convert or get similiar result ?

Passing a null or nothing value to a datatime datatype database field (Access)
I've been all over the internet looking at this and I have tried dozens of methods without success.
I've read a few forums where, some say you can not assign a null value or a nothing value to a datetime datatype field. Then I see others where they say...'I got it to work'.
If this is true (that you can not pass a null value), how come I can create a record in the Access table and not assign a value to this date field? (The field is defined as not required).
Yet, once a value is in the field, I can not update that field back to a null or a nothing value.
So I'm hoping someone has the definitive answer to this.
I am using VB.Net Vs 2003 and updating an Access data base.
I have an update statement (see below) that uses parameters for updating.
what will work, so that I can put back the null or nothing value?
Or if it really can not be done, I guess I'll have to take that as truth.

I'm passing a model to a view, and the model contains this attribute:
[Required(ErrorMessage = "Please enter a start date")]
[DataType(DataType.DateTime)]
[DisplayName("Start Date")]
public DateTime StartDate { get; set; }
And I have this in my view:
<%: Html.TextBoxFor(m => m.StartDate) %>
When I load the page, the textbox is populated with a date: 1/1/0001 12:00:00 AM
Is there a way to not have this happen, maybe by using metadata?
I have a datetime column where I store the amount of time a person workded on a project, so it might be 2011-02-16 05:00:00.000 in the column, this being 5 hours. I need to get a sum of the hours in my sproc I tried
[Code]....
But it tells me I cannot sum on datetime.
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.
Yes..i know this is ASP.NEt forums but the SQL server doubt i will be going to ask is related to ASP.NET

I'm using DAAB from MS Ent Library 4.1. I have this function in my DAL that returns a dataset.

However, it is failing with this error:Failed to convert parameter value from a String to a Boolean.
But if I use SqlDbType.VarChar instead it works fine. I want to use Char b/c that is the correct datatype in SQL.In my SP the param is @CUSTNMBR char(15). In my database table the field is also char(15).

I've inherited a SQL Server 2005 table where there are several colums of the image datatype. I'd like to extract all of those images and save them as files to a folder. How can I do this using VB.NET?

I am using VS 2008.I am building a datatable of records to be inserted into a SQL Server 2005 table.
The program loops through this table and builds a SqlParameter for each DataColumn in the datatable. The SqlParameters are used in the SQL Insert statement.
The field I am having a problem with is of type 'bit' in the database table and has no default value and cannot be nulls. The field is called 'Active' The meaning of this field in the application is Boolean i.e True or False. When inserting the record, I wish to default the field to "False".
When I define the columns in the datatable I am forced to use the following code to build the datatcolumn containing the boolean field i.e. dtcActive.DataType = GetType(Boolean) as there is no GetType(Bit)
Dim dtcActive As New DataColumn("Active")
dtcActive.DataType = GetType(Boolean)
dtcActive.Unique = False
dtcActive.AllowDBNull = False
dtcActive.DefaultValue = False
dtProviderDayDetails.Columns.Add(dtcActive)
However, when I build the SqlParameter I am forced to use this:
If field.ColumnName = "Active" Then
prm.SqlDbType = SqlDbType.Bit
prm.Value = "False"
End If
This is because there is no SqlDbType.Boolean. The problem I have is there is no value I have been able to give the SqlParameter that is accepted by the Insert statement. It complains that the boolean field cannot be null on Insert.
I am using SQL SERVER 2008 database. I have a table Customers in which the CustomerID column is had datatype INT intially but due to increase in Customers the number range is exceeding which may cause error arithmetic overflow of data. Hence I thought to modify the datatype from INT to BIGINT and wrote an alter script but when I ran the script it failed. Hence provide me in creating alter script for the updating the datatype of the primarykey column for the Customers table.

How to get Column Data Type in Autogenerated Grid View ?
View 1 RepliesYou'd think since MS SQl Server 2008 and asp.net are both Microsoft products, asp.net would support the new "time" datatype but anyway.
This is one data field in gridview called "timesort"

I have a column with nvarchar datatype storing the date. I am using a Gridview to display and edit data of that table. Now when I update the table the nvarchar column containing date in the format mm/dd/yyyy gets converted to Jun 9 2010 12:00AM format. I don't want this to be happening. I don't understand why this is happening as I don't have datetime column.
