  #386411

  I'm trying to write a C# CLR stored procedure which needs to take a datetime2(3) as a parameter.

  However, mapping the parameter as a SqlDateTime causes the error:

  CREATE PROCEDURE for "myProcedure" failed because T-SQL and CLR types for parameter "@startDT" do not match.

  It appears that SqlDateTime still maps to the SQL DateTime accurate to 3.3 millisecs

  Any ideas appreciated as I'm now very confused.

  SqlDateTime still maps to the SQL Server datetime data type, yes. If I remember correctly, I think the System.DateTimeOffset type will accept a datetime2 without complaint or loss of precision.

  E.g.:

  [Microsoft.SqlServer.Server.SqlFunction]

  [return: SqlFacet(MaxSize=21)]

  public static SqlString datetime2_test( DateTimeOffset datetime )

  {

  if ( datetime == null )

  return DateTime.Now.ToString( "yyyyMMddHHmmssfffffff" );

  else

  return datetime.ToString( "yyyyMMddHHmmssfffffff" );

  }

  What is the CLR for? I mean, what is it supposed to do?

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.
