That is a PDO bug not a PDO_MYSQL bug. It has been fixed in PHP 5.3+. ext/pdo/pdo_stmt.c:330 needs something like this: int len = spprintf(&p, 0, "%.*H", (int) EG(precision), Z_DVAL_P(param->parameter)); I don't know what the policy is with PHP 5.2. Would be nice if someone else could apply the patch. I am quite sure to have seen this bug before and I am also sure the 5.3 tests cover it. Though, I can't say which test from top of my head.

The same problem happens with a float field, in this case it saves maximum 5 decimals I didn't try with other dbms, my Mysql version is 5.1.36 (i verified that the problem happens also with older versions) Reproduce code: --------------- This saves only 6 decimal (using bindValue): $sth = $dbh->prepare("INSERT INTO `intrapportal`.`regioni` ( `idRegione` ,`descrRegione` , `provadouble` ) VALUES ('xxxx', 'yyyyy', :value)"); /*** bind values ***/ $sth->bindValue(':value', 9.1234567, PDO::PARAM_STR); /*** execute the prepared statement ***/ $sth->execute(); This saves all decimals (without bindValue) $sth = $dbh->prepare("INSERT INTO `intrapportal`.`regioni` ( `idRegione` ,`descrRegione` , `provadouble` ) VALUES ('xxxx', 'yyyyy', 9.1234567)"); /*** execute the prepared statement ***/ $sth->execute(); ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48855&edit=1
