I made some tests with this table
Table name: tbl1
Cloumns: id INTEGER
this code work ok:
-----------------------
try {
$sql='UPDATE tbl1 SET tbl1.id=10'
$results = $dbh->query($sql);
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
This code will crash the server: (WHERE 1=1)
-----------------------------------
try {
$sql='UPDATE tbl1 SET tbl1.id=10 WHERE 1=1'
$results = $dbh->query($sql);
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
----------------------------
I try some bad SQL syntax ("Us543PDATE tbl1 SET tbl1.id=10"), same
result server crash.
this statment :
UPDATE tbl1 SET tbl1.id=5 WHERE tbl1.id=10
after some test surprisly this statment work, but again after some more
test again this stament produce crash.
hope this information be helpful.

Can you provide a CREATE TABLE statement or a small copy of your actual
.mdb file, so that I can test against the same schema you're using?

Sorry, I know this is going to be difficult to duplicate as I'm
connecting to a Access DB on my local machine via ODBC. If you have a
Access DB on your system, you just need to set it up in your ODBC
Manager and point to that DSN in the script. Once that is done, try
doing a Update SQL command via PDO::query, Then try it via PDO::exec.
If it works (correctly), it should return the number of rows affected.
It crashes for me on the query, and does nothing on the exec.

<?php
try
{
$dbh = new PDO('odbc:DSN=TEST;driver=Driver do Microsoft Access
(*.mdb)','','');
$results = $dbh->query('UPDATE xd17 SET xd17.CCDate = 20051207,
xd17.CCTime = 1200, xd17.ModifiedDS = 200512071200 WHERE xd17.XTyp17 =
157 AND xd17.X15A = 51921 AND xd157.X105B = 3300');
} catch (PDOException $e) {
print "Error!: ".$e->getMessage()."<br/>";
die();
}
?>

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.
