 A syntax error (#42000) is returned when trying to use a decimal parameter
in a select query.

I looked at the Serialize method of MySqlDecimal class and it
writes one byte to inform the server the length of the decimal value
followed by the value itself.

I'm new to MySQL but I believe the error is either caused by this serialization format or by a server error when parsing the query.

How to repeat:
create a table (t1) with 2 fields : f1 (int) and f2 (decimal).
create a .NET application and try to open a datareader
using the following statement : "select * from t1 where f2 = ?f2 "
and of course using a parameter of type MySqlDecimal.
