oci_fetch_all

(PHP 5, PECL OCI8 >= 1.1.0)

oci_fetch_all — Fetches multiple rows from a query into a two-dimensional array

Description int oci_fetch_all ( resource $statement , array &$output [, int $skip = 0 [, int $maxrows = -1 [, int $flags = OCI_FETCHSTATEMENT_BY_COLUMN + OCI_ASSOC ]]] ) Fetches multiple rows from a query into a two-dimensional array. By default, all rows are returned.

This function can be called only once for each query executed with oci_execute().

Parameters

statementoci_parse() and executed by oci_execute(), or a statement identifier.

output

LOB columns are returned as strings, where Oracle supports conversion.

skip maxrows flags oci_fetch_all() Array Structure Modes Constant Description OCI_FETCHSTATEMENT_BY_ROW The outer array will contain one sub-array per query row. OCI_FETCHSTATEMENT_BY_COLUMN The outer array will contain one sub-array per query column. This is the default.

Arrays can be indexed by column heading or numerically. oci_fetch_all() Array Index Modes Constant Description OCI_NUM Numeric indexes are used for each column's array. OCI_ASSOC Associative indexes are used for each column's array. This is the default.

Use the addition operator "+" to choose a combination of array structure and index modes.

Oracle's default, non-case sensitive column names will have uppercase array keys. Case-sensitive column names will have array keys using the exact column case. Use var_dump() on output

Queries that have more than one column with the same name should use column aliases. Otherwise only one of the columns will appear in an associative array.

Return Values

Returns the number of rows in outputFALSE on failure.

Examples

Example #1 oci_fetch_all() example

$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

$stid = oci_parse($conn, 'SELECT POSTAL_CODE, CITY FROM locations WHERE ROWNUM < 3');
oci_execute($stid);

$nrows = oci_fetch_all($stid, $res);

echo "$nrows rows fetched<br>\n";
var_dump($res);

// var_dump output is:
//    2 rows fetched
//    array(2) {
//      ["POSTAL_CODE"]=>
//      array(2) {
//        [0]=>
//        string(6) "00989x"
//        [1]=>
//        string(6) "10934x"
//      }
//      ["CITY"]=>
//      array(2) {
//        [0]=>
//        string(4) "Roma"
//        [1]=>
//        string(6) "Venice"
//      }
//    }

// Pretty-print the results
echo "<table border='1'>\n";
foreach ($res as $col) {
    echo "<tr>\n";
    foreach ($col as $item) {
        echo "    <td>".($item !== null ? htmlentities($item, ENT_QUOTES) : " ")."</td>\n";
    }
    echo "</tr>\n";
}
echo "</table>\n";

oci_free_statement($stid);
oci_close($conn);

Example #2 oci_fetch_all() example with OCI_FETCHSTATEMENT_BY_ROW

$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

$stid = oci_parse($conn, 'SELECT POSTAL_CODE, CITY FROM locations WHERE ROWNUM < 3');
oci_execute($stid);

$nrows = oci_fetch_all($stid, $res, null, null, OCI_FETCHSTATEMENT_BY_ROW);

echo "$nrows rows fetched<br>\n";
var_dump($res);

// Output is:
//    2 rows fetched
//    array(2) {
//      [0]=>
//      array(2) {
//        ["POSTAL_CODE"]=>
//        string(6) "00989x"
//        ["CITY"]=>
//        string(4) "Roma"
//      }
//      [1]=>
//      array(2) {
//        ["POSTAL_CODE"]=>
//        string(6) "10934x"
//        ["CITY"]=>
//        string(6) "Venice"
//      }
//    }

oci_free_statement($stid);
oci_close($conn);

Example #3 oci_fetch_all() with OCI_NUM

$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

$stid = oci_parse($conn, 'SELECT POSTAL_CODE, CITY FROM locations WHERE ROWNUM < 3');
oci_execute($stid);

$nrows = oci_fetch_all($stid, $res, null, null, OCI_FETCHSTATEMENT_BY_ROW + OCI_NUM);

echo "$nrows rows fetched<br>\n";
var_dump($res);

// Output is:
//    2 rows fetched
//    array(2) {
//      [0]=>
//      array(2) {
//        [0]=>
//        string(6) "00989x"
//        [1]=>
//        string(4) "Roma"
//      }
//      [1]=>
//      array(2) {
//        [0]=>
//        string(6) "10934x"
//        [1]=>
//        string(6) "Venice"
//      }
//    }

oci_free_statement($stid);
oci_close($conn);
Notes

Note: Using skipoci_fetch_array() for an example.

Note: Queries that return a large number of rows can be more memory efficient if a single-row fetching function like oci_fetch_array() is used.

Note: For queries returning a large number of rows, performance can be significantly improved by increasing oci8.default_prefetch or using oci_set_prefetch().

Note: In PHP versions before 5.0.0 you must use ocifetchstatement() instead. The old function name can still be used in current versions, however it is deprecated and not recommended.
