int OCINewCursor(int conn);OCINewCursor() allocates a new statement handle on the specified connection.
Example 1. Using a REF CURSOR from a stored procedure <?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($data);
}
OCIFreeCursor($stmt);
OCIFreeStatement($curs);
OCILogoff($conn);
?> |
Example 2. Using a REF CURSOR in a select statement <?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);
