Example 2. Using a REF CURSOR in a select statement in Oracle
<?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); ?>
