oci_new_cursor

(PHP 5)

oci_new_cursor -- Allocates and returns a new cursor (statement handle)

Description

resource oci_new_cursor ( resource connection)

oci_new_cursor() allocates a new statement handle on the specified connection.

Example 1. Using REF CURSOR in an Oracle's stored procedure

<?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. Using REF CURSOR in an Oracle's select statement

<?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() returns FALSE on error.

Note: In PHP versions before 5.0.0 you must use ocinewcursor() instead. This name still can be used, it was left as alias of oci_new_cursor() for downwards compatability. This, however, is deprecated and not recommended.
