I am using Ejabberd server for chatting application. It works to save messages in arhieve table, but I want to save additional field in the table when message is sent. This field will be per message.
Igor, Thanks for your answer, looks promising, but I did something else which I want to share here. I have installed ejabberd from source code with help of this link http://www.blikoon.com/networking/how-to-install-ejabberd-on-linux-ubuntu then I modified mod_mam_sql.erl file in src folder. Code I modified is as follow. I recompiled module and it worked.
Body = fxml:get_subtag_cdata(Pkt, <<"body">>),
Resid = fxml:get_subtag_cdata(Pkt, <<"resid">>),
Ownuid = fxml:get_subtag_cdata(Pkt, <<"ownuid">>),
SType = jlib:atom_to_binary(Type),
case ejabberd_sql:sql_query(
LServer,
?SQL("insert into archive (username, timestamp,"
" peer, bare_peer, xml, txt, kind, nick,resid,Ownuid) values ("
"%(SUser)s, "
"%(TSinteger)d, "
"%(LPeer)s, "
"%(BarePeer)s, "
"%(XML)s, "
"%(Body)s, "
"%(SType)s, "
"%(Nick)s, "
"%(Resid)s, "
"%(Ownuid)s)")) of
{updated, _} ->
{ok, ID};
