這條命令開始一個新的事務。如果聲明了隔離級別或者讀寫模式， 那麼新事務就使用這個特性，如同執行了 SET TRANSACTION [set_transaction(7)] 一樣。在其它方面，這條命令的行為和 BEGIN [begin(7)] 命令一樣。

這條命令開始一個新的事務。如果聲明了隔離級別或者讀寫模式， 那麼新事務就使用這個特性，如同執行了 SET TRANSACTION [set_transaction(7)] 一樣。在其它方面，這條命令的行為和 BEGIN [begin(7)] 命令一樣。
參閱 SET TRANSACTION [set_transaction(7)] 獲取有關參數含義的信息。
這條命令兼容 SQL 標準；但是又見 SET TRANSACTION [set_transaction(7)] 的兼容性小節。

NAMESTART TRANSACTION - start a transaction block
SYNOPSISSTART TRANSACTION [ ISOLATION LEVEL { READ COMMITTED | SERIALIZABLE } ] [ READ WRITE | READ ONLY ]
DESCRIPTIONThis command begins a new transaction. If the isolation level or read/write mode is specified, the new transaction has those characteristics, as if SET TRANSACTION [set_transaction(7)] was executed. In all other respects, the behavior of this command is identical to the BEGIN [begin(7)] command.
PARAMETERSSee under SET TRANSACTION [set_transaction(7)] about the meaning of the parameters.
COMPATIBILITYThis command conforms to the SQL standard; but see also the compatibility section of SET TRANSACTION [set_transaction(7)].
SEE ALSOBEGIN [begin(7)], COMMIT [commit(l)], ROLLBACK [rollback(l)], SET TRANSACTION [set_transaction(l)]
