<div><div class="p">Consider the following items when deciding when to end a transaction: <ul><li>You can only commit or roll back the current transaction, so keep dependent
|
||
|
|
statements within the same transaction.</li>
|
||
|
|
<li>Various locks are held while you have an outstanding transaction. Ending
|
||
|
|
the transaction releases the locks, and allows access to the data by other
|
||
|
|
users. This is the case for all SQL statements, including SELECT statements.</li>
|
||
|
|
<li>As soon as a transaction has successfully been committed
|
||
|
|
or rolled back, it is fully recoverable from the system logs (this depends
|
||
|
|
on the Database Management System (DBMS)). Open transactions are not recoverable.</li>
