The conversion of a datetime2 data type to a datetime data type RRS feed

  • Question

  • I have a field in my database with a DateTime datatype. Am also using EF4.1 fluent API to persist data into the database and am ending up getting this exceptions 

    {"The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value.\r\nThe statement has been terminated."}
    I know the easy way to fix this is to change the DataType in the database to datetime2(7) but my problem is I don't want EF to be changing datatype just because EF is asking me to do so. Nhibernate and Other ORM tools dont complain. Is there a way around this?


    Thanks

  • Hi Edward,

    Welcome to the forum.

     

    The DateTime2 is a new type in the SQL2008 for more accurate.

    The entity framework 4 will convert the DateTime to DateTime2 by default.

    So Could you tell me the Version of your database, visual studio, and the type in your *.edmx

    For the solution:

    1、You can try to set the ProvidermanifestToken as 2005;

    2、You can try to assign the value as:

         From entity.CreateTime= new DateTime(2011,7,11,5,20,10,123);

     

    I hope that would be help you.

     

    Best Regards.
