Re: Oracle PDO UTF-8 problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Doesn't work.

I got the following error after i set the parameter in the PDO construct

Fatal error: Undefined class constant 'MYSQL_ATTR_MAX_BUFFER_SIZE'

IMHO this is only a MYSQL parameter but i worked with oracle.

Hello

I try to read a 2000 character long string out of database. The database is
an oracle 10g Express Edition with UTF-8 character set. To read the string
we use the PDO abstraction layer with oci-driver. If the 2000 character
contains one or more UTF-8 characters we get the problem that PDO truncate
the result of the database, with the following message:

Warning: PDOStatement::fetchAll() [pdostatement.fetchall]: column 5 data
was too large for buffer and was truncated to fit it in
C:\wamp\www\wp\bp.php on line 115


The definition of the database column is

TESTSTRING VARCHAR2(2000 CHAR)

CHAR means that we can store up to 2000 characters independent from the
encoding of the character (e.g. UTF8).


I also init the PDO with UTF8

$dbh = new PDO('oci:dbname=' . $db_name . ';charset=UTF8', $db_user,
$db_pw);


If i read the same string with java and JDBC-driver it works fine, so i can
exclude a database error.

How i have to configre PHP/PDO to be aware of the truncation of the result
string?
