OCINewCursor

(PHP 3>= 3.0.8, PHP 4)

OCINewCursor - возвращает новый курсор (Statement-Handle/дескриптор оператора).

Описание

int OCINewCursor (int conn)

OCINewCursor() выделяет новый дескриптор оператора в специфицированном соединении.

Пример 1. Использование REF CURSOR из хранимой процедуры
<?php   
// предположим, что ваша хранимая процедура info.output возвращает ref-курсор в :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);
?>
Пример 2. Использование REF CURSOR в операторе выборки/select
<?php   
print "<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);
print "<TABLE BORDER=\"1\">";
print "<TR>";
print "<TH>DEPT NAME</TH>";
print "<TH>DEPT #</TH>";
print "<TH># EMPLOYEES</TH>";
print "</TR>";

while (OCIFetchInto($stmt,&$data,OCI_ASSOC)) {
    print "<TR>";
    $dname  = $data["DNAME"];
    $deptno = $data["DEPTNO"];
    print "<TD>$dname</TD>";
    print "<TD>$deptno</TD>";
    ociexecute($data["EMPCNT"]);
    while (OCIFetchInto($data["EMPCNT"],&$subdata,OCI_ASSOC)) {
        $num_emps = $subdata["NUM_EMPS"];
        print  "<TD>$num_emps</TD>";
    }
    print "</TR>";
}
print "</TABLE>";
print "</BODY></HTML>";
OCIFreeStatement($stmt);
OCILogoff($conn);
?>
