ODPI-C Function Round-Trips
***************************
The following table identifies if round-trips to the database are required when
calling each of the functions that ODPI-C supports. A round-trip is defined as
the trip from the Oracle Client libraries (used by ODPI-C) to the database and
back.

:summary: The first column displays the function. The second column
indicates if round-trips to the database are required. The third column
displays the relevant notes.
* - Function
- Round-Trips?
- Notes
* - :func:`dpiConn_addRef()`
- No
- No relevant notes
* - :func:`dpiConn_breakExecution()`
- Yes
- No relevant notes
* - :func:`dpiConn_changePassword()`
- Yes
- No relevant notes
* - :func:`dpiConn_close()`
- Maybe
- If the connection was acquired from a pool, a round-trip is only
required if the parameter *mode* is set to the value
**DPI_MODE_CONN_CLOSE_DROP**. For standalone connections, a round-trip
is always required. If there is an open transaction, a round-trip is
also required to perform the implicit rollback that takes place.
* - :func:`dpiConn_commit()`
- Yes
- No relevant notes
* - :func:`dpiConn_create()`
- Maybe
- If a standalone connection is being created, one round-trip is
required. If a connection is being acquired from a pool, no round-trips
are required if an unused connection is available in the pool;
otherwise, a round trip is required for each connection that is added
to the pool (see :member:`dpiPoolCreateParams.sessionIncrement`).
* - :func:`dpiConn_deqObject()`
- Yes
- No relevant notes
* - :func:`dpiConn_enqObject()`
- Yes
- No relevant notes
* - :func:`dpiConn_getCallTimeout()`

* - :func:`dpiConn_getLTXID()`
- No
- No relevant notes
* - :func:`dpiConn_getMaxOpenCursors()`
- No
- No relevant notes
* - :func:`dpiConn_getObjectType()`
- Maybe
- If the type information is already available in the Oracle Client
object cache, only one round trip is required; otherwise, two
round-trips are required unless the type contains embedded types or is
a collection. In that case additional round-trips are required to fetch
the additional type information.
* - :func:`dpiConn_getOciAttr()`
- No
- No relevant notes
* - :func:`dpiConn_getServerVersion()`
- Maybe
- The first call when requesting the release string always requires a
round-trip. If the release string is not requested and Oracle Client
20.3 or higher is being used, no round-trip is required. Similarly for
earlier versions, if the release string is not requested and a pooled
connection is used that previously had a call to this function made, no
round-trip is required; otherwise, a round-trip is required. Subsequent
calls with any client version do not require a round-trip.
* - :func:`dpiConn_getServiceName()`
- No
- No relevant notes
* - :func:`dpiConn_getSodaDb()`
- Maybe
- An internal call to check the server version is made. The notes on the
function :func:`dpiConn_getServerVersion()` apply.

- No relevant notes
* - :func:`dpiConn_release()`
- Maybe
- If the number of references exceeds 1 or the connection has already
been closed by a call to :func:`dpiConn_close()` then no round-trips
are required; otherwise, the connection is closed at this point and the
notes on the function :func:`dpiConn_close()` apply.
