oci_fetch_object
Returns the next row from a query as an object
Description
stdClassfalse oci_fetch_object(resource $statement, int $mode = OCI_ASSOC | OCI_RETURN_NULLS)
For details on the data type mapping performed by
the OCI8 extension, see the datatypes
supported by the driver
Parameters
-
statement
-
A valid OCI8 statement
identifier created by oci_parse and executed
by oci_execute, or a REF
CURSOR statement identifier.
Return Values
Returns an object. Each attribute of the object corresponds to a
column of the row. If there are no more rows in
the statement then false is returned.
Any LOB columns are returned as LOB descriptors.
DATE columns are returned as strings formatted
to the current date format. The default format can be changed with
Oracle environment variables such as NLS_LANG or
by a previously executed ALTER SESSION SET
NLS_DATE_FORMAT command.
Oracle's default, non-case sensitive column names will have
uppercase attribute names. Case-sensitive column names will have
attribute names using the exact column case.
Use var_dump on the result object to verify
the appropriate case for attribute access.
Attribute values will be null for any NULL
data fields.
Examples
Example #1 oci_fetch_object example
<?php
/*
Before running, create the table:
CREATE TABLE mytab (id NUMBER, description VARCHAR2(30));
INSERT INTO mytab (id, description) values (1, 'Fish and Chips');
COMMIT;
*/
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$stid = oci_parse($conn, 'SELECT id, description FROM mytab');
oci_execute($stid);
while (($row = oci_fetch_object($stid)) != false) {
// Use upper case attribute names for each standard Oracle column
echo $row->ID . "<br>\n";
echo $row->DESCRIPTION . "<br>\n";
}
// Output is:
// 1
// Fish and Chips
oci_free_statement($stid);
oci_close($conn);
?>
Example #2 oci_fetch_object with case sensitive column names
<?php
/*
Before running, create the table with a case sensitive column name:
CREATE TABLE mytab (id NUMBER, "MyDescription" VARCHAR2(30));
INSERT INTO mytab (id, "MyDescription") values (1, 'Iced Coffee');
COMMIT;
*/
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$stid = oci_parse($conn, 'SELECT id, "MyDescription" FROM mytab');
oci_execute($stid);
while (($row = oci_fetch_object($stid)) != false) {
// Use upper case attribute names for each standard Oracle column
echo $row->ID . "<br>\n";
// Use the exact case for the case sensitive column name
echo $row->MyDescription . "<br>\n";
}
// Output is:
// 1
// Iced Coffee
oci_free_statement($stid);
oci_close($conn);
?>
Example #3 oci_fetch_object with LOBs
<?php
/*
Before running, create the table:
CREATE TABLE mytab (id NUMBER, description CLOB);
INSERT INTO mytab (id, description) values (1, 'A very long string');
COMMIT;
*/
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$stid = oci_parse($conn, 'SELECT id, description FROM mytab');
oci_execute($stid);
while (($row = oci_fetch_object($stid)) != false) {
echo $row->ID . "<br>\n";
// The following will output the first 11 bytes from DESCRIPTION
echo $row->DESCRIPTION->read(11) . "<br>\n";
}
// Output is:
// 1
// A very long
oci_free_statement($stid);
oci_close($conn);
?>
