pg_transaction_status

(PHP 5 >= 5.1.0RC1)

pg_transaction_status -- Returns the current in-transaction status of the server.

Описание

int pg_transaction_status ( resource connection )

Returns the current in-transaction status of the server.

Предостережение

pg_transaction_status() will give incorrect results when using a PostgreSQL 7.3 server that has the parameter autocommit set to off. The server-side autocommit feature has been deprecated and does not exist in later server versions.

Список параметров

connection

PostgreSQL database connection resource.

Возвращаемые значения

The status can be PGSQL_TRANSACTION_IDLE (currently idle), PGSQL_TRANSACTION_ACTIVE (a command is in progress), PGSQL_TRANSACTION_INTRANS (idle, in a valid transaction block), or PGSQL_TRANSACTION_INERROR (idle, in a failed transaction block). PGSQL_TRANSACTION_UNKNOWN is reported if the connection is bad. PGSQL_TRANSACTION_ACTIVE is reported only when a query has been sent to the server and not yet completed.
