无法在 EF 访问的存储过程中将 NVARCHAR 转换为 datetime2

Question

I am trying to execute a stored procedure from C#

var dt = new SqlParameter("ExportedOn", DateTime.Now);
context.Database.ExecuteSqlCommand("EXEC LogDataExport @ExportedOn", dt);

Stored procedure:

CREATE PROCEDURE LogDataExport
    (@ExportedOn DATETIME2)
AS 
    INSERT INTO dbo.DataExportLogging (Id, ExportedOn, Description, Text)
        SELECT 1, @ExportedOn, 'asd', 'dsasadfsdag'
GO

I get an error that dt cannot be converted from NVARCHAR to Datetime2 .

Answer 1

If you like server side solution you can set-up the dbo.DataExportLogging.ExportedOn column default value as getdate() .
