IBASE_TRANS(3) 1 IBASE_TRANS(3)
ibase_trans - Begin a transaction
SYNOPSIS
resource ibase_trans ([int $trans_args], [resource $link_identifier])
DESCRIPTION
resource ibase_trans ([resource $link_identifier], [int $trans_args])
Begins a transaction.
Note
The first call to ibase_trans(3) will not return the default transaction of a connection. All transactions started by
ibase_trans(3) will be rolled back at the end of the script if they were not committed or rolled back by either ibase_commit(3) or
ibase_rollback(3).
Note
This function will accept multiple $trans_args and $link_identifier arguments. This allows transactions over multiple database con-
nections, which are committed using a 2-phase commit algorithm. This means you can rely on the updates to either succeed in every
database, or fail in every database. It does NOT mean you can use tables from different databases in the same query!
If you use transactions over multiple databases, you will have to specify both the $link_id and $transaction_id in calls to
ibase_query(3) and ibase_prepare(3).
PARAMETERS
o $trans_args
-$trans_args can be a combination of IBASE_READ, IBASE_WRITE, IBASE_COMMITTED, IBASE_CONSISTENCY, IBASE_CONCURRENCY,
IBASE_REC_VERSION, IBASE_REC_NO_VERSION, IBASE_WAIT and IBASE_NOWAIT.
o $link_identifier
- An InterBase link identifier. If omitted, the last opened link is assumed.
RETURN VALUES
