prepare command is not implemented

[dragonemp]

Issue description

using parameter and prepare is usually the best way to avoid sql injection. but when i try to call command.prepare(), i'm getting not implemented exception

Example code

var param = cmd.CreateParameter();
param.ParameterName = "nameQuery";
param.DbType = DbType.String;
param.Value = model.Query;
cmd.Parameters.Add(param);
...
cmd.CommandText = $"{sql}";
cmd.Prepare();
reader = cmd.ExecuteReader();

Error log

{System.NotImplementedException: The method or operation is not implemented.

There is an example in READMD.md file showing you how to enable logging.

hello and thank you for raising this issue. apologies for the long period without response. Prepare() is indeed not implemented even in the latest version of the driver, so we'll take a look.
