pg_lo_import — Import a large object from file
pg_lo_import() creates a new large object in the database using a file on the filesystem as its data source.
To use the large object interface, it is necessary to enclose it within a transaction block.
Nota:
This function used to be called pg_loimport().
connection
Uma instância de PgSql\Connection. Quando o parâmetro connection
não for especificado, a conexão padrão será usada. A conexão padrão é a última conexão feita por pg_connect() ou pg_pconnect().
A partir do PHP 8.1.0, usar a conexão padrão tornou-se defasado.
pathname
The full path and file name of the file on the client filesystem from which to read the large object data.
object_id
If an object_id
is given the function will try to create a large object with this id, else a free object id is assigned by the server. The parameter relies on functionality that first appeared in PostgreSQL 8.1.
The OID of the newly created large object, ou false
em caso de falha.
Versão | Descrição |
