The following constants can be passed to ibase_trans()
to specify transaction behaviour.
表 2. Firebird/InterBase transaction flags
| Constant | Description |
|---|
| IBASE_DEFAULT |
The default transaction settings are to be used. This default is
determined by the client library, which defines it as
IBASE_WRITE|IBASE_CONCURRENCY|IBASE_WAIT in most cases. |
| IBASE_READ | Starts a read-only transaction. |
| IBASE_WRITE | Starts a read-write transaction. |
| IBASE_CONSISTENCY | Starts a transaction with the isolation level set to
'consistency', which means the transaction cannot read from tables
that are being modified by other concurrent transactions. |
| IBASE_CONCURRENCY | Starts a transaction with the isolation level set to
'concurrency' (or 'snapshot'), which means the transaction
has access to all tables, but cannot see changes that were committed
by other transactions after the transaction was started. |
| IBASE_COMMITTED | Starts a transaction with the isolation level set to
'read committed'. This flag should be combined with either
IBASE_REC_VERSION or
IBASE_REC_NO_VERSION. This isolation level
allows access to changes that were committed after the transaction
was started. If IBASE_REC_NO_VERSION was
specified, only the latest version of a row can be read. If
IBASE_REC_VERSION was specified, a row can
even be read when a modification to it is pending in a concurrent
transaction.
|
| IBASE_WAIT | Indicated that a transaction should wait and retry when a
conflict occurs. |
| IBASE_NOWAIT | Indicated that a transaction should fail immediately when a
conflict occurs. |
The following constants can be passed to ibase_fetch_row(),
ibase_fetch_assoc() or ibase_fetch_object()
to specify fetch behaviour.
表 3. Firebird/InterBase fetch flags
| Constant | Description |
|---|
| IBASE_FETCH_BLOBS | Also available as IBASE_TEXTfor backward
compatibility. Causes BLOB contents to be fetched inline, instead of
being fetched as BLOB identifiers. |
| IBASE_FETCH_ARRAYS | Causes arrays to be fetched inline. Otherwise, array
identifiers are returned. Array identifiers can only be used as
arguments to INSERT operations, as no functions to handle array
identifiers are currently available.
|
| IBASE_UNIXTIME | Causes date and time fields not to be returned as strings,
but as UNIX timestamps (the number of seconds since the epoch, which
is 1-Jan-1970 0:00 UTC). Might be problematic if used with dates
before 1970 on some systems.
