Method MySqlCommand.TokenizeSql() ends a token when a valid parameter-name character is found - it uses too limited set of valid characters. Currently the method stops "recording" a parameter-name token when it is not letter-or-digit and not '_'. I think more characters are valid in parameter name, for example '$' character.

How to repeat:
See description.

Suggested fix:
Parameter names seems to not use same restrictions as user variables (according to manual valid characters for user variables are "alphanumeric characters from the current character set, `.', `_', and `$'."). I have tested that '$' is valid but '.' is not.

If only a '$' character is missing from the valid set, the line 627-628 in command.cs (method MySqlCommand.TokenizeSql()) then should look like this:

else if (sqlPart.Length > 0 && sqlPart[0] == parameters.ParameterMarker &&
 !Char.IsLetterOrDigit(c) && c != '_' && c != '$') // '$' is added as valid character for parameter name
{ // code then goes on unchanged
