SYNOPSIS

START TRANSACTION [ ISOLATION LEVEL { READ COMMITTED | SERIALIZABLE } ] [ READ WRITE | READ ONLY ]

PARAMETERS 參數(shù)

 參閱 SET TRANSACTION [set_transaction(7)] 獲取有關(guān)參數(shù)含義的信息。  

COMPATIBILITY 兼容性

 這條命令兼容 SQL 標(biāo)準(zhǔn)；但是又見 SET TRANSACTION [set_transaction(7)] 的兼容性小節(jié)。  

SEE ALSO 參見

BEGIN [begin(7)], COMMIT [commit(l)], ROLLBACK [rollback(l)], SET TRANSACTION [set_transaction(l)]

NAME

START TRANSACTION - start a transaction block

SYNOPSIS

START TRANSACTION [ ISOLATION LEVEL { READ COMMITTED | SERIALIZABLE } ] [ READ WRITE | READ ONLY ]

DESCRIPTION

This 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.  

PARAMETERS

See under SET TRANSACTION [set_transaction(7)] about the meaning of the parameters.  

COMPATIBILITY

This command conforms to the SQL standard; but see also the compatibility section of SET TRANSACTION [set_transaction(7)].  

SEE ALSO

BEGIN [begin(7)], COMMIT [commit(l)], ROLLBACK [rollback(l)], SET TRANSACTION [set_transaction(l)]
