## node-oracledb v1.9.0 (DD Mon YYYY)
|
|
|
|
## node-oracledb v1.8.0 (24 Mar 2016)
|
|
|
|
- Added `connection.queryStream()` for returning query results using a
|
|
Node Readable Stream (Sagie Gur-Ari).
|
|
|
|
- Connection strings requesting DRCP server can now only be used with
|
|
a node-oracledb connection pool. They will give *ORA-56609* when
|
|
used with `oracledb.getConnection()`.
|
|
|
|
- Set the internal driver name to `node-oracledb : 1.8.0`. This is
|
|
visible to DBAs, for example in `V$SESSION_CONNECT_INFO`.

|
|
- Added up-time to pool queue statistics.
|
|
|
|
- Fixed creation of Windows debug builds.
|
|
|
|

|
|
|
|
- Improved test date and time checks (Antonio Bustos).

|
|
|

|
`queueTimeout` attributes. The queue is enabled by default.
|
|
|
|
- Added connection pool option attribute `_enableStats` and method
|
|
`pool._logStats()` to display pool and queue statistics. Note: these may
|
|
change in future.
|
|
|
|
- Added "bind by position" syntax for PL/SQL Index-by array binds (Dieter Oberkofler).
|
|
|
|

|
|
|
|

|
|
|
|
- Added RPATH support on Linux.
|
|
|

|
|
|
|
- Fixed a crash using pooled connections on Windows.
|
|
|
|

|
|
|
