<para>

This command begins a new transaction. If the isolation level or
|
|
read/write mode is specified, the new transaction has those
|
|
characteristics, as if <xref linkend="sql-set-transaction"
|
|
endterm="sql-set-transaction-title"> was executed. In all other
|
|
respects, the behavior of this command is identical to the <xref
|
|
linkend="sql-begin" endterm="sql-begin-title"> command.
