Dear Matt, Even with MySQL, u get the warning as the show warnings is enabled. With php bound scripts, you have to check warnings to see the warnings. However, php is quite flexible and you an use error_reporting(E_WARNING) for non-fatal error reporting regds amit On Aug 21, 2012 10:41 AM, "Matt Pelmear" <mjpelmear@xxxxxxxxx> wrote: > On 08/21/2012 01:08 AM, David Robley wrote: > >> Matt Pelmear wrote: >> >> Hello, >>> >>> I'm trying to detect data truncation on insert to MySQL using PDO. >>> >>> As far as I can tell, this gets reported at least in some cases (ex: >>> http://drupal.org/node/1528628**), but I have been unable to see this >>> myself. >>> >>> The test table I'm using has a column that is VARCHAR(5): >>> >>> mysql> describe test; >>> +-------+------------------+--**----+-----+---------+-------+ >>> | Field | Type | Null | Key | Default | Extra | >>> +-------+------------------+--**----+-----+---------+-------+ >>> | id | int(10) unsigned | YES | | NULL | | >>> | data | varchar(5) | YES | | NULL | | >>> +-------+------------------+--**----+-----+---------+-------+ >>> 2 rows in set (0.00 sec) >>> >>> >>> My test script inserts a ten character string into the 5 character >>> column: >>> >>> ==== PHP TEST CODE ==== >>> >>> $pdo = new PDO( >>> 'mysql:host=localhost;dbname=**test', >>> 'username', >>> 'password' >>> ); >>> >>> $pdo->setAttribute(PDO::ATTR_**ERRMODE, PDO::ERRMODE_EXCEPTION); >>> >>> $retval = $pdo->query( 'INSERT INTO `test` (data) VALUES ("1234567890")' >>> ); >>> >>> print_r( $retval ); >>> >>> ==== END TEST CODE ==== >>> >>> This results in a new row in the `test` table, truncated after the 5th >>> character as expected, but the truncation is not reported.
