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).
