ErlOCI - A low level Oracle driver for Erlang

Getting started

Read the README for compilation instructions

Create a driver instance

application:start(erloci).
OciPort = erloci:new([{logging, true}, {env, [{"NLS_LANG", "GERMAN_SWITZERLAND.AL32UTF8"}]}]).

note the use of optional environment variable(s) NLS_LANG which effects OCI directly (transparent to erloci)

executing a simple select query

OciSession = OciPort:get_session(Tns, User, Pswd).
SelStmt = OciSession:prep_sql("select * from dual").
{cols,[{<<"DUMMY">>,'SQLT_CHR',_,0,0}]} = SelStmt:exec_stmt()).
{{rows,[ [<<"X">>] ]},true} = SelStmt:fetch_rows(100)).

Cleanup a driver instance

OciPort:close().
application:stop(erloci).
