(PHP 5, PECL OCI8 >= 1.1.0)
oci_new_cursor — 分配并返回一個新的游標（語句句柄）
說明
resource oci_new_cursor ( resource$connection
)
oci_new_cursor() 在指定的連接上分配一個新的語句句柄。
Example #1 在 Oracle 的存儲過程中使用 REF CURSOR
<?php
// suppose your stored procedure info.output returns a ref cursor in :data
$conn = oci_connect("scott", "tiger");
$curs = oci_new_cursor($conn);
$stmt = oci_parse($conn, "begin info.output(:data); end;");
oci_bind_by_name($stmt, "data", $curs, -1, OCI_B_CURSOR);
oci_execute($stmt);
oci_execute($curs);
while ($data = oci_fetch_row($curs)) {
var_dump($data);
}
oci_free_statement($stmt);
oci_free_statement($curs);
oci_close($conn);
?>
Example #2 在 Oracle 的 select 語句中使用 REF CURSOR
<?php
echo "<html><body>";
$conn = oci_connect("scott", "tiger");
$count_cursor = "CURSOR(select count(empno) num_emps from emp " .
"where emp.deptno = dept.deptno) as EMPCNT from dept";
$stmt = oci_parse($conn, "select deptno,dname,$count_cursor");
oci_execute($stmt);
echo "<table border="1">";
echo "<tr>";
echo "<th>DEPT NAME</th>";
echo "<th>DEPT #</th>";
echo "<th># EMPLOYEES</th>";
echo "</tr>";
while ($data = oci_fetch_assoc($stmt)) {
echo "<tr>";
$dname = $data["DNAME"];
$deptno = $data["DEPTNO"];
echo "<td>$dname</td>";
echo "<td>$deptno</td>";
oci_execute($data["EMPCNT"]);
while ($subdata = oci_fetch_assoc($data["EMPCNT"])) {
$num_emps = $subdata["NUM_EMPS"];
echo "<td>$num_emps</td>";
}
echo "</tr>";
}
echo "</table>";
echo "</body></html>";
oci_free_statement($stmt);
oci_close($conn);
?>
oci_new_cursor() 如果出錯返回 FALSE。
Note:
在 PHP 5.0.0 之前的版本必須使用 ocinewcursor() 替代本函數(shù)。該函數(shù)名仍然可用，為向下兼容作為 oci_new_cursor() 的別名。不過其已被廢棄，不推薦使用。
