oci_fetch
OCI_FETCH(3) OCI_FETCH(3)
oci_fetch - Fetches the next row from a query into internal buffers
SYNOPSIS
bool oci_fetch (resource $statement)
DESCRIPTION
Fetches the next row from a query into internal buffers accessible either with oci_result(3), or by using variables previously defined
with oci_define_by_name(3).
See oci_fetch_array(3) for general information about fetching data.
PARAMETERS
o $statement
-A valid OCI8 statement identifier created by oci_parse(3) and executed by oci_execute(3), or a REF CURSOR statement identifier.
RETURN VALUES
Returns TRUE on success or FALSE if there are no more rows in the $statement.
EXAMPLES
Example #1
oci_fetch(3) with defined variables
<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$sql = 'SELECT location_id, city FROM locations WHERE location_id < 1200';
$stid = oci_parse($conn, $sql);
// The defines MUST be done before executing
oci_define_by_name($stid, 'LOCATION_ID', $locid);
oci_define_by_name($stid, 'CITY', $city);
oci_execute($stid);
// Each fetch populates the previously defined variables with the next row's data
while (oci_fetch($stid)) {
echo "Location id $locid is $city<br>
";
}
// Displays:
// Location id 1000 is Roma
// Location id 1100 is Venice
oci_free_statement($stid);
oci_close($conn);
?>
Example #2
oci_fetch(3) with oci_result(3)
<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$sql = 'SELECT location_id, city FROM locations WHERE location_id < 1200';
$stid = oci_parse($conn, $sql);
oci_execute($stid);
while (oci_fetch($stid)) {
echo oci_result($stid, 'LOCATION_ID') . " is ";
echo oci_result($stid, 'CITY') . "<br>
";
}
// Displays:
// 1000 is Roma
// 1100 is Venice
oci_free_statement($stid);
oci_close($conn);
?>
