DB_common::getAll()

DB_common::getAll() -- Runs a query and returns all the data as an array

Referentiesamenvatting

array &getAll (string $query [, array $params = array() [, integer $fetchmode = DB_FETCHMODE_DEFAULT]])

Beschrijving

Runs the query provided and puts the entire result set into a nested array then frees the result set.

Parameter

string $query

the SQL query or the statement to prepare

array $params

array to be used in execution of the statement. Quantity of array elements must match quantity of placeholders in query.

If supplied, prepare()/ execute() is used.

Waarschuwing

This method does not allow scalars to be used for this argument.

integer $fetchmode

the fetch mode to use. The default is DB_FETCHMODE_DEFAULT, which tells this method to use DB's current fetch mode. The current fetch mode can be changed using setFetchMode(). Potential values include:

DB_FETCHMODE_ORDERED
DB_FETCHMODE_ASSOC
DB_FETCHMODE_OBJECT
DB_FETCHMODE_ORDERED | DB_FETCHMODE_FLIPPED
DB_FETCHMODE_ASSOC | DB_FETCHMODE_FLIPPED

Return waarde

array - a nested array or a DB_Error on failure

Throws

Tabel 35-1. Mogelijke PEAR_Error waarden

Error code	Error message	Reason	Solution
`DB_ERROR_INVALID`	invalid	SQL statment for preparing is not valid.	See the prepare() documentation, if you want to use a SQL statemt using placeholders.
`DB_ERROR_MISMATCH`	mismatch	Quantity of parameters didn't match quantity of placeholders in the prepared statment.	Check that the number of placeholders in the prepare() statement passed to `$query` equals the count of entries passed to `$params`.
`DB_ERROR_NODBSELECTED`	no database selected	No database was choosen.	Check the DSN in connect().
every other error code		Database specific error	Check the database related section of PHP-Manual to detect the reason for this error. In the most cases a misformed SQL statment. Ie. using LIMIT in a SQL-Statment for an Oracle database.

Note

Deze functie kan niet statisch worden aangeroepen.

Voorbeeld

Voorbeeld 35-1. Using getAll() to return an associative array by setting the default fetch mode first


<?php
// Once you have a valid DB object named $db...
$db->setFetchMode(DB_FETCHMODE_ASSOC);
$data =& $db->getAll('SELECT cf, nf, df FROM foo');

if (PEAR::isError($data)) {
    die($data->getMessage());
}

print_r($data);
?>

Output:

Array
(
    [0] => Array
        (
            [cf] => Juan
            [nf] => 5
            [df] => 1991-01-11 21:31:41
        )
    [1] => Array
        (
            [cf] => Kyu
            [nf] => 10
            [df] => 1992-02-12 22:32:42
        )
)

Voorbeeld 35-2. Using getAll() to return an ordered array


<?php
// Once you have a valid DB object named $db...
$data =& $db->getAll('SELECT cf, nf, df FROM foo',
        array(), DB_FETCHMODE_ORDERED);

if (PEAR::isError($data)) {
    die($data->getMessage());
}

print_r($data);
?>

Output:

Array
(
    [0] => Array
        (
            [0] => Juan
            [1] => 5
            [2] => 1991-01-11 21:31:41
        )
    [1] => Array
        (
            [0] => Kyu
            [1] => 10
            [2] => 1992-02-12 22:32:42
        )
)

Voorbeeld 35-3. Using getAll() to return a flipped ordered array


<?php
// Once you have a valid DB object named $db...
$data =& $db->getAll('SELECT cf, nf, df FROM foo',
        array(), DB_FETCHMODE_ORDERED | DB_FETCHMODE_FLIPPED);

if (PEAR::isError($data)) {
    die($data->getMessage());
}

print_r($data);
?>

Output:

Array
(
    [0] => Array
        (
            [0] => Juan
            [1] => Kyu
        )
    [1] => Array
        (
            [0] => 5
            [1] => 10
        )
    [2] => Array
        (
            [0] => 1991-01-11 21:31:41
            [1] => 1992-02-12 22:32:42
        )
)

Voorbeeld 35-4. Using getAll() to return an associative array


<?php
// Once you have a valid DB object named $db...
$data =& $db->getAll('SELECT cf, nf, df FROM foo',
        array(), DB_FETCHMODE_ASSOC);

if (PEAR::isError($data)) {
    die($data->getMessage());
}

print_r($data);
?>

Output:

Array
(
    [0] => Array
        (
            [cf] => Juan
            [nf] => 5
            [df] => 1991-01-11 21:31:41
        )
    [1] => Array
        (
            [cf] => Kyu
            [nf] => 10
            [df] => 1992-02-12 22:32:42
        )
)

Voorbeeld 35-5. Using getAll() to return a flipped associative array


<?php
// Once you have a valid DB object named $db...
$data =& $db->getAll('SELECT cf, nf, df FROM foo',
        array(), DB_FETCHMODE_ASSOC | DB_FETCHMODE_FLIPPED);

if (PEAR::isError($data)) {
    die($data->getMessage());
}

print_r($data);
?>

Output:

Array
(
    [cf] => Array
        (
            [0] => Juan
            [1] => Kyu
        )
    [nf] => Array
        (
            [0] => 5
            [1] => 10
        )
    [df] => Array
        (
            [0] => 1991-01-11 21:31:41
            [1] => 1992-02-12 22:32:42
        )
)

Voorbeeld 35-6. Using getAll() to return an array of objects


<?php
// Once you have a valid DB object named $db...
$data =& $db->getAll('SELECT cf, nf, df FROM foo',
        array(), DB_FETCHMODE_OBJECT);

if (PEAR::isError($data)) {
    die($data->getMessage());
}

print_r($data);
?>

Output:

Array
(
    [0] => stdClass Object
        (
            [cf] => Juan
            [nf] => 5
            [df] => 1991-01-11 21:31:41
        )
    [1] => stdClass Object
        (
            [cf] => Kyu
            [nf] => 10
            [df] => 1992-02-12 22:32:42
        )
)

Voorbeeld 35-7. Using getAll() in prepare/execute mode to return an associative array


<?php
// Once you have a valid DB object named $db...
$data =& $db->getAll('SELECT cf, nf, df FROM foo WHERE nf = ?',
        array(5), DB_FETCHMODE_ASSOC);

if (PEAR::isError($data)) {
    die($data->getMessage());
}

print_r($data);
?>

Output:

Array
(
    [0] => Array
        (
            [cf] => Juan
            [nf] => 5
            [df] => 1991-01-11 21:31:41
        )
