oci_fetch
(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)
oci_fetch — Fetches the next row into result-buffer
说明
oci_fetch
( resource $statement
) : bool
oci_fetch() 获取下一行(对于 SELECT 语句)到内部结果缓冲区。
Note:
在 PHP 5.0.0 之前的版本必须使用 ocifetch() 替代本函数。该函数名仍然可用,为向下兼容作为 oci_fetch() 的别名。不过其已被废弃,不推荐使用。
返回值
Returns true
on success or false
if there are no more rows in the
statement
.
范例
Example #1 oci_fetch() with defined variables
<?php$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, $sql);// The defines MUST be done before executingoci_define_by_name($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 datawhile (oci_fetch($stid)) { echo "Location id $locid is $city<br>\n";}// Displays:// Location id 1000 is Roma// Location id 1100 is Veniceoci_free_statement($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($stid, 'CITY') . "<br>\n";}// Displays:// 1000 is Roma// 1100 is Veniceoci_free_statement($stid);oci_close($conn);?>
注释
Note:
In PHP versions before 5.0.0 use ocifetch() instead.
