Using PL/SQL Ref Cursors to Return Result Sets

Beta Draft Executing Stored Procedures and Functions 6-7

In the Results section, confirm the package body is successfully created:

3. Edit anyco_db.inc. Create a new PHP function that calls the PL/SQL packaged

procedure:

// Use ref cursor to fetch employee records

// All records are retrieved - there is no paging in this example

function db_get_employees_rc($conn, $deptid, &$e)

{

// Excute the call to the stored procedure

$stmt = "BEGIN cv_types.get_employees($deptid, :rc); END;";

$stid = @oci_parse($conn, $stmt);

if (!$stid) {

$e = db_error($conn, __FILE__, __LINE__);

return false;

}

$refcur = oci_new_cursor($conn);

if (!$stid) {

$e = db_error($conn, __FILE__, __LINE__);

return false;

}

$r = @oci_bind_by_name($stid, ':RC', $refcur, -1, OCI_B_CURSOR);

if (!$r) {

$e = db_error($stid, __FILE__, __LINE__);

return false;

}

$r = @oci_execute($stid);

if (!$r) {

$e = db_error($stid, __FILE__, __LINE__);

return false;

}

// Now treat the ref cursor as a statement resource

$r = @oci_execute($refcur, OCI_DEFAULT);

if (!$r) {

$e = db_error($refcur, __FILE__, __LINE__);

return false;

}

$r = @oci_fetch_all($refcur, $employeerecords, null, null,

OCI_FETCHSTATEMENT_BY_ROW);
