[erlang-questions] Erlang ODBC best practices

Hi All,

I am currently using an in-memory database which offers ODBC connectivity (Oracle Times Ten).

Of course given I am using ODBC I need to generate and pass SQL commands to the DB. I was wondering what is the best way to organise SQL statements (canned) and build up dynamic SQL statements within Erlang?

Currently I just have my static SQL commands in a .hrl file and as a crude example access them as such:

    odbc:start(),

    {ok, Ref} = odbc:connect("DSN=TT_HWHU;UID=aUID;PWD=aPWD", [{scrollable_cursors, off}]),

    {selected, ColNames, Data} = odbc:sql_query(Ref, ?TESTSQL),


Does anyone know of a better way of doing this? In particular building up an SQL statement dynamically - for example in an insert statement?

Many Thanks,
Dan
