    <p>My database table is like this</p> <pre><code>CREATE TABLE MYBUDGET.tbl_CurrentProperty ( [PropID] INT NOT NULL IDENTITY(1,1), [UpdatedOn] DATETIME NOT NULL, [Amount] MONEY NOT NULL, [Remarks] VARCHAR(100) NOT NULL, ) ALTER TABLE MYBUDGET.tbl_CurrentProperty ADD CONSTRAINT PK_CurrentProperty_PropID PRIMARY KEY ([PropID]) ALTER TABLE MYBUDGET.tbl_CurrentProperty ADD CONSTRAINT DF_CurrentProperty_UpdatedOn DEFAULT (DATEADD(MINUTE,30,DATEADD(HOUR, 5, GETUTCDATE()))) FOR [UpdatedOn] ALTER TABLE MYBUDGET.tbl_CurrentProperty ADD CONSTRAINT CK_CurrentProperty_Amount CHECK([Amount] &gt; -1) GO </code></pre> <p>I'm using LINQ to SQL. In C# I need to pass only [Amount] and [Remarks] fields and other fields must be used with their default values ([PropID] and [UpdatedOn]).</p> <p>In C# I create tbl_CurrentProperties object like below,</p> <pre><code>tbl_CurrentProperties currentProperties = new tbl_CurrentProperties(); currentProperties.Amount = 50.00M; currentProperties.Remarks = "remarks"; </code></pre> <p>and then submit the object to the data context. But here, Linq assigned <code>'1/1/0001 12:00:00 AM'</code> for UpdatedOn field. But this violate the SQL datetime range <code>1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM</code> and Occurring an exception. Also I can't assign a NULL value manually for a <code>DateTime</code> field since its a not nullable type. Anyhow I need to make this to use its DEFAULT Constraint. How do I do this?</p> <hr> <p>PS: I want to use it like this because, My database is Online and Users are in different locations. So If I used DateTime.Now, the time in the user machine may be wrong, and It insert a wrong value into DB. I need to use SQL server time always.</p>

    1. COOf course, if you moved your business logic out of your database and into your code, then you wouldn't have this issue :-)

    3. CO@Andrey: A lot of people would strongly disagree with you. Maybe this was acceptable 10 years ago, but now all business logic should arguably be centralised in code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
