TRANSACTION(7) SQL Commands START TRANSACTION(7) NAME
START TRANSACTION - start a transaction block SYNOPSIS
START TRANSACTION [ transaction_mode [, ...] ] where transaction_mode is one of: ISOLATION LEVEL { SERIALIZABLE | REPEATABLE READ | READ COMMITTED | READ UNCOMMITTED } READ WRITE | READ ONLY DESCRIPTION
This command begins a new transaction block. If the isolation level or read/write mode is specified, the new transaction has those charac- teristics, as if SET TRANSACTION [set_transaction(7)] was executed. This is the same as the BEGIN [begin(7)] command. PARAMETERS
Refer to SET TRANSACTION [set_transaction(7)] for information on the meaning of the parameters to this statement. COMPATIBILITY
In the standard, it is not necessary to issue START TRANSACTION to start a transaction block: any SQL command implicitly begins a block. PostgreSQL's behavior can be seen as implicitly issuing a COMMIT after each command that does not follow START TRANSACTION (or BEGIN), and it is therefore often called ``autocommit''. Other relational database systems might offer an autocommit feature as a convenience. The SQL standard requires commas between successive transaction_modes, but for historical reasons PostgreSQL allows the commas to be omit- ted. See also the compatibility section of SET TRANSACTION [set_transaction(7)]. SEE ALSO
