    pg_lo_import — Import a large object from file

    Açıklama

    pg_lo_import(PgSql\Connection $connection = ?, string $pathname, mixed $object_id = ?): int

    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.

    Bilginize:

    This function used to be called pg_loimport().

    Bağımsız Değişkenler

    connection

    PgSql\Connection nesnesi. bağlantı belirtilmemişse öntanımlı bağlantı kullanılır. Öntanımlı bağlantı pg_connect() veya pg_pconnect() işleviyle kurulmuş son bağlantıdır.

    Uyarı

    PHP 8.1.0 ve sonrasında, öntanımlı bağlantının kullanımı önerilmemektedir.

    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.

    Dönen Değerler

    The OID of the newly created large object, başarısızlık durumunda false döner.

    Sürüm Bilgisi

    Sürüm: Açıklama
    8.1.0 bağlantı bağımsız değişkeni artık PgSql\Connection nesnesi kabul ediyor, evvelce bir özkaynak kabul ederdi.

    its not very clear if pg_lo_import needs to have pg_lo_open called first. Because pg_lo_import handles the process of writign to the file, it seems logical that pg_lo_open does not need to be called. However due to the ugly nature of how postgres handles oid objects, it would be nice to have this documented.

    Due to a bug, OLD API does not available with PHP 4.2.0 and 4.2.1.

    PHP 4.2.2 will support OLD API again and will be kept long enough.

    New API will be available PHP 4.2.0 to later versions.

    Due to a bug, PHP 4.2.0 and 4.2.1 does not support pg_lo_import() old API. It's fixed in PHP 4.2.2.

    BTW, new API will be always available from PHP 4.2.0 to later versions. Older API will be kept long enough, also.

    it works for me (php-4.2.1)

    not like this

    int pg_lo_import ( string pathname [, resource connection])

    but
    int pg_lo_import ( resource connection, string pathname )

    don't know the reason
