    pg_field_table — Returns the name or oid of the tables field

    Descripción

    pg_field_table(PgSql\Result$result, int$field, bool$oid_only = false): string|int|false

    pg_field_table() returns the name of the table that field belongs to, or the table's oid if oid_only is true.

    Parámetros

    result

    An PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).

    field

    Field number, starting from 0.

    oid_only

    By default the tables name that field belongs to is returned but if oid_only is set to true, then the oid will instead be returned.

    Valores devueltos

    On success either the fields table name or oid, o false en caso de error.

    8.1.0 The result parameter expects an PgSql\Result instance now; previously, a recurso was expected.

    Ejemplos

    Ejemplo #1 Getting table information about a field

    <?php
    $dbconn     = pg_connect("dbname=publisher") or die("Could not connect");

    $res = pg_query($dbconn, "SELECT bar FROM foo");

    echo     pg_field_table($res, 0);
    echo     pg_field_table($res, 0, true);

    $res = pg_query($dbconn, "SELECT version()");
    var_dump(pg_field_table($res, 0));
    ?>

    El resultado del ejemplo sería algo similar a:

    foo 14379580 bool(false)

    Notas

    Nota:

    Returning the oid is much faster than returning the table name because fetching the table name requires a query to the database system table.
