oci_fetch_object

(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)

oci_fetch_object — Returns the next row from a query as an object

설명

object oci_fetch_object ( resource $statement )

Returns an object containing the next result-set row of a query. Each attribute of the object corresponds to a column of the row. This function is typically called in a loop until it returns FALSE, indicating no more rows exist.

인수

statement: A valid OCI8 statement identifier created by oci_parse() and executed by oci_execute(), or a REF CURSOR statement identifier.

반환값

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.

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);

?>

Please note that you can still reference a column that has a very complex name by using the curly syntax as shown in this example:

<?php

$queryStr = 'SELECT COUNT(*) FROM FOOBAR';  //Complex name!
  // parse and exec...
$queryObj = oci_fetch_object($quertStmt);
 
echo 'Count: ' . $queryObj->{'COUNT(*)'};  //Curly syntax reference

?>
