oci_fetch()

(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)

Fetches the next row into result-buffer

说明

oci_fetch(resource $statement): bool

oci_fetch()获取下一行（对于 SELECT 语句）到内部结果缓冲区。

Note:

在 PHP 5.0.0 之前的版本必须使用ocifetch()替代本函数。该函数名仍然可用，为向下兼容作为oci_fetch()的别名。不过其已被废弃，不推荐使用。

参数

$statement

有效的 OCI8 报表标识符由oci_parse()创建，被oci_execute()或REF CURSORstatement 标识执行。

返回值

Returns TRUE on success or FALSE if there are no more rows in the$statement.

范例

Example #1 oci_fetch() with defined variables

<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$sql = 'SELECT location_id, city FROM locations WHERE location_id < 1200';
$stid = oci_parse($conn, $sql);
// The defines MUST be done before executing
oci_define_by_name($stid, 'LOCATION_ID', $locid);
oci_define_by_name($stid, 'CITY', $city);
oci_execute($stid);
// Each fetch populates the previously defined variables with the next row's data
while (oci_fetch($stid)) {
    echo "Location id $locid is $city<br>\n";
}
// Displays:
//   Location id 1000 is Roma
//   Location id 1100 is Venice
oci_free_statement($stid);
oci_close($conn);
?>

Example #2 oci_fetch() with oci_result()

<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$sql = 'SELECT location_id, city FROM locations WHERE location_id < 1200';
$stid = oci_parse($conn, $sql);
oci_execute($stid);
while (oci_fetch($stid)) {
    echo oci_result($stid, 'LOCATION_ID') . " is ";
    echo oci_result($stid, 'CITY') . "<br>\n";
}
// Displays:
//   1000 is Roma
//   1100 is Venice
oci_free_statement($stid);
oci_close($conn);
?>

注释

Note:

In PHP versions before 5.0.0 use ocifetch() instead.在当前版本中，旧的函数名还可以被使用，但已经被废弃并不建议使用。
