Describe the bug

Create function:

CREATE FUNCTION TestFunction2(ColSet set('set1','set2','set3'))
RETURNS smallint
BEGIN
	RETURN 0;
END

Call this function

            using MySqlConnector.MySqlConnection conn = new("XXXXXXXXXX");
            conn.Open();

            using DbCommand sqlCmd = conn.CreateCommand();
            sqlCmd.Connection = conn;
            sqlCmd.CommandText = @"TestFunction2";
            sqlCmd.CommandType = System.Data.CommandType.StoredProcedure;

            DbParameter param23 = sqlCmd.CreateParameter();
            param23.ParameterName = "@ColSet";
            param23.Value = "set1";
            sqlCmd.Parameters.Add(param23);

            DbParameter paramXXX = sqlCmd.CreateParameter();
            paramXXX.ParameterName = "@ReturnValue";
            paramXXX.Direction = System.Data.ParameterDirection.ReturnValue;
            sqlCmd.Parameters.Add(paramXXX);

            var result = sqlCmd.ExecuteScalar();
