Scalar-valued functions can be called from .NET as follows:

SqlCommand cmd = new SqlCommand('testFunction', sqlConn); //testFunction is scalar cmd.CommandType = CommandType.StoredProcedure;   cmd.Parameters.Add('retVal', SqlDbType.Int); cmd.Parameters['retVal'].Direction = ParameterDirection.ReturnValue; cmd.ExecuteScalar(); int aFunctionResult = (int)cmd.Parameters['retVal'].Value;

I also know that table-valued functions can be called in a similar fashion, for example: 

String query = 'select * from testFunction(param1,...)'; //testFunction is table-valued SqlCommand cmd = new SqlCommand(query, sqlConn); SqlDataAdapter adapter = new SqlDataAdapter(cmd); adapter.Fill(tbl);

My question is, can table-valued functions be called as stored procedures, like scalar-valued functions can? (e.g., replicate my first code snippet with a table-valued function being called and getting the returned table through a ReturnValue parameter).

  1. No because you need to select them. However you can create a stored proc wrapper, which may defeat the point of having a table function.
