oci_fetch_object

oci_fetch_object

(PHP 5, PECL OCI8 >= 1.1.0)

oci_fetch_objectReturns the next row from a query as an object

说明

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.

参数

statement

有效的 OCI8 报表标识符 由 oci_parse() 创建,被 oci_execute()REF CURSOR statement 标识执行。

返回值

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 to use for each query.

Attribute values will be NULL for any NULL data fields.

范例

Example #1 oci_fetch_object() example

<?php



$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))) {
    
// Use upper case attribute names for each standard Oracle column
    
echo $row->ID "<br> ";
    echo 
$row->DESCRIPTION "<br> "
}

// Output is:
//    1
//    Fish and Chips

oci_free_statement($stid);
oci_close($conn);

?>

Example #2 oci_fetch_object() with case sensitive column names

<?php



$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))) {
    
// Use upper case attribute names for each standard Oracle column
    
echo $row->ID "<br> ";
    
// Use the exact case for the case sensitive column name
    
echo $row->MyDescription "<br> ";   
}

// Output is:
//    1
//    Iced Coffee

oci_free_statement($stid);
oci_close($conn);

?>

Example #3 oci_fetch_object() with LOBs

<?php



$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))) {
    echo 
$row->ID "<br> ";
    
// The following will output the first 11 bytes from DESCRIPTION
    
echo $row->DESCRIPTION->read(11) . "<br> "
}

// Output is:
//    1
//    A very long

oci_free_statement($stid);
oci_close($conn);

?>
