Description: When a stored procedure is called using a mysqlcommand - populating its parameters collection - an error occurs: #42000Incorrect number of arguments for PROCEDURE sp_test; expected 1; got 0 this is the stack trace for mysqlexception object: at MySql.Data.MySqlClient.Driver.ReadPacket() at MySql.Data.MySqlClient.Driver.Send(DBCmd cmd, Byte[] bytes) at MySql.Data.MySqlClient.InternalConnection.ExecuteCmd(DBCmd cmd, Byte[] buffer, Boolean consume) at MySql.Data.MySqlClient.MySqlCommand.GetNextResultSet(MySqlDataReader reader) at MySql.Data.MySqlClient.MySqlDataReader.NextResult() at MySql.Data.MySqlClient.MySqlCommand.ExecuteReader(CommandBehavior behavior) at MySql.Data.MySqlClient.MySqlCommand.ExecuteReader() at WindowsApplicationTest.Form1.button1_Click(Object sender, EventArgs e) in c:\\documents and settings\\elabora_46\\documenti\\progetti di visual studio\\windowsapplicationtest\\form1.cs:line 261 mysql server version: 5.0.1 alpha. The sp functions correctly into mysql client. How to repeat: create this simple stored procedure on MySql Server 5.0.1 alpha: CREATE PROCEDURE sp_test(par0 int) begin select par0; end then run this code: MySqlConnection cn = new MySqlConnection(); cn.ConnectionString = "Data Source=localhost;database=testdb;"; cn.Open(); MySqlCommand cm = new MySqlCommand(); cm.CommandType = CommandType.StoredProcedure; cm.Connection = cn; cm.CommandText = "sp_test"; cm.Parameters.Add("par0", MySqlDbType.Int32).Value = 3; MySqlDataReader dr = cm.ExecuteReader(CommandBehavior.SingleResult);
