ocinewcursor() 在特定的连接上分配一个新的语句句柄。
例子 1. 从一个 Oracle 的储存过程中使用一个 REF CURSOR
<?php
// suppose your stored procedure info.output returns a ref cursor in :data
$conn = OCILogon("scott", "tiger");
$curs = OCINewCursor($conn);
$stmt = OCIParse($conn, "begin info.output(:data); end;");
ocibindbyname($stmt, "data", &$curs, -1, OCI_B_CURSOR);
ociexecute($stmt);
ociexecute($curs);
while (OCIFetchInto($curs, &$data)) {
var_dump($data);
}
OCIFreeStatement($stmt);
OCIFreeCursor($curs);
OCILogoff($conn);
?>

例子 2. 在 Oracle 的 select 语句中使用 REF CURSOR
<?php
echo "<html><body>";
$conn = OCILogon("scott", "tiger");
$count_cursor = "CURSOR(select count(empno) num_emps from emp " .
"where emp.deptno = dept.deptno) as EMPCNT from dept";
$stmt = OCIParse($conn, "select deptno,dname,$count_cursor");
ociexecute($stmt);
echo "<table border=\"1\">";
echo "<tr>";
echo "<th>DEPT NAME</th>";
echo "<th>DEPT #</th>";
echo "<th># EMPLOYEES</th>";
echo "</tr>";
while (OCIFetchInto($stmt, &$data, OCI_ASSOC)) {
echo "<tr>";
$dname = $data["DNAME"];
$deptno = $data["DEPTNO"];
echo "<td>$dname</td>";
echo "<td>$deptno</td>";
ociexecute($data["EMPCNT"]);
while (OCIFetchInto($data["EMPCNT"], &$subdata, OCI_ASSOC)) {
$num_emps = $subdata["NUM_EMPS"];
echo "<td>$num_emps</td>";
}
echo "</tr>";
}
echo "</table>";
echo "</body></html>";
OCIFreeStatement($stmt);
OCILogoff($conn);
?>
