c++ - Count field incorrect syntax error -

for last several days i'm trying connect store procedure using odbc. crecordset code:

sp_insertsesmessagestore::sp_insertsesmessagestore(cdatabase* pdb)  : crecordset(pdb){ // param init m_return_value = -1; m_provider_idparam = _t(""); m_branch_idparam = _t(""); m_accountparam = _t(""); m_ses_user_unique_idparam = _t(""); m_display_nameparam = _t(""); m_smtp_addressparam = _t(""); m_message_type_idparam = 0; m_priorityparam = 0; m_subjectparam = _t(""); m_summaryparam = _t(""); m_template_idparam = _t(""); m_body_type_idparam = 0; m_tracking_idparam = _t(""); m_expiration_timeparam = _t(""); m_subcategory_idparam = 0; m_folder_idparam = 0; m_num_attachmentsparam = 0; m_access_idparam = _t(""); m_flagsparam = 0; m_favoriteparam = false; m_certified_idparam = _t(""); m_secure_response_otpparam = _t(""); m_message_idparam = _t(""); m_nparams = 24;  m_ndefaulttype = snapshot;} 

this dodataexchange.

void sp_insertsesmessagestore::dofieldexchange(cfieldexchange* pfx){ // rfx output param mapping /*pfx->setfieldtype(cfieldexchange::outputparam); rfx_long(pfx, _t("[@return_value]"), m_return_value);*/  // rfx input param mapping pfx->setfieldtype(cfieldexchange::inputparam); rfx_text(pfx, _t("[@provider_id]"), m_provider_idparam, 3); rfx_text(pfx, _t("[@branch_id]"), m_branch_idparam, 50); rfx_text(pfx, _t("[@account]"), m_accountparam, 255); rfx_text(pfx, _t("[@ses_user_unique_id]"), m_ses_user_unique_idparam, 8); rfx_text(pfx, _t("[@display_name]"), m_display_nameparam, 255); rfx_text(pfx, _t("[@smtp_address]"), m_smtp_addressparam, 255); rfx_int(pfx, _t("[@message_type_id]"), m_message_type_idparam); rfx_byte(pfx, _t("[@priority]"), m_priorityparam); rfx_text(pfx, _t("[@subject]"), m_subjectparam, 255); rfx_text(pfx, _t("[@summary]"), m_summaryparam, 255); rfx_text(pfx, _t("[@template_id]"), m_template_idparam, 255); rfx_int(pfx, _t("[@body_type_id]"), m_body_type_idparam); rfx_text(pfx, _t("[@tracking_id]"), m_tracking_idparam, 255); rfx_text(pfx, _t("[@expiration_time]"), m_expiration_timeparam, 16); rfx_int(pfx, _t("[@subcategory_id]"), m_subcategory_idparam); rfx_int(pfx, _t("[@folder_id]"), m_folder_idparam); rfx_int(pfx, _t("[@num_attachments]"), m_num_attachmentsparam); rfx_longbinary(pfx, _t("[@body]"), m_bodyparam); rfx_text(pfx, _t("[@access_id]"), m_access_idparam, 255); rfx_long(pfx, _t("[@flags]"), m_flagsparam); rfx_bool(pfx, _t("[@favorite]"), m_favoriteparam); rfx_text(pfx, _t("[@certified_id]"), m_certified_idparam, 100); rfx_text(pfx, _t("[@secure_response_otp]"), m_secure_response_otpparam, 50);  // rfx input_output param mapping pfx->setfieldtype(cfieldexchange::inoutparam); rfx_text(pfx, _t("[@message_id]"), m_message_idparam, 8);}  bool sp_insertsesmessagestore::execdirect(){ return open(crecordset::forwardonly, getdefaultsql(), crecordset::executedirect);} 

this statement i'm passing.

cstring sp_insertsesmessagestore::getdefaultsql(){ return _t("{call sp_insertsesmessagestore (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)}");} 

this auto generated code tool found on web. had isolated problem, cause of exception clongbinary member, can't find issue, suggestions?!
