<h1>Description</h1>
|
|
<p>The <i>txn</i> <b>abort</b> command causes an abnormal termination of the
|
|
transaction.
|
|
<p>The log is played backwards and any necessary recovery operations are
|
|
performed. After recovery is completed, all locks held by the
|
|
transaction are acquired by the parent transaction in the case of a
|
|
nested transaction or released in the case of a non-nested transaction.
|
|
As is the case for <i>txn</i> <b>commit</b>, applications that require strict
|
|
two-phase locking should not explicitly release any locks.
|
|
<p>In the case of nested transactions, aborting the parent transaction
|
|
causes all children of that transaction to be aborted.
|
|
<p>Once <i>txn</i> <b>abort</b> has been called, regardless of its return, the
|
|
<b>txn</b> handle may not be accessed again.
|
|
<p>The <i>txn</i> <b>abort</b> command returns 0 on success, and in the case of error, a Tcl error
|
|
is thrown.
