Thank you for a problem report. Please, send the results of the SHOW CREATE TABLE user_states statement. What version of MySQL server are you connecting to?

I am using MySql 5.0.18-nt. Here's the results you asked for: 'user_states', 'CREATE TABLE `user_states` ( `user_id` int(11) NOT NULL default '0', `state` varchar(2) NOT NULL default '', `uid` int(10) unsigned NOT NULL auto_increment, PRIMARY KEY (`uid`), KEY `FK_user_states_users` (`user_id`), CONSTRAINT `FK_user_states_users` FOREIGN KEY (`user_id`) REFERENCES `users` (`user_id`) ON DELETE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='InnoDB free: 11264 kB; (`user_id`) REFER `recruiting_listser''

I have been dealing with the same issue. Changing UInt16 or UInt32 to the corresponding Int in the parameter definition made it work.

Description: Stored procedure as follows: CREATE PROCEDURE `insert_user_states`( IN param_user_id integer(9), IN param_state varchar(2)) BEGIN INSERT INTO user_states(user_id, state) VALUES (param_user_id, param_state); END C# code as follows: private void SaveUserStates(string states, int user_id) { StringBuilder sbErrors = new StringBuilder(); MySqlCommand cmdInsert = MySqlCnn.CreateCommand(); cmdInsert.CommandType = CommandType.StoredProcedure; cmdInsert.CommandText = "insert_user_states"; cmdInsert.Parameters.Add("param_user_id", MySqlDbType.UInt16, 9); cmdInsert.Parameters["param_user_id"].Value = 44; cmdInsert.Parameters.Add("param_state", MySqlDbType.VarChar, 2); cmdInsert.Parameters["param_state"].Value = "ss"; try { MySqlCnn.Open(); cmdInsert.ExecuteNonQuery(); } catch(MySqlException MySqlEx) { sbErrors.Append("MySql error in SaveUserStates: " + MySqlEx.Message); Debug.WriteLine(sbErrors.ToString()); } catch (Exception ex) { sbErrors.Append("Exception in SaveUserStates: " + ex.Message); Debug.WriteLine(sbErrors.ToString()); } finally { MySqlCnn.Close(); } } Executing this code results in this error: "MySql error in SaveUserStates: Only byte arrays and strings can be serialized by MySqlBinary" How to repeat: See description above. As of this writing I have not found a workaround. Other stored procedures that are similar are working fine.
