Description
This command begins a new transaction block. If the isolation level or
read/write mode is specified, the new transaction has those
characteristics, as if SET TRANSACTION was executed. This is the same
as the BEGIN command.
Compatibility
In the standard, it is not necessary to issue START TRANSACTION
to start a transaction block: any SQL command implicitly begins a block.
EnterpriseDB'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 may offer an autocommit feature
as a convenience.
The SQL standard requires commas between successive transaction_modes, but for historical
reasons EnterpriseDB allows the commas to be
omitted.
