Question

When I execute a pdo that specifies some but not all fields in a table, it inserts fine on one server, but fails to insert on the other server.

FOR EXAMPLE, ON THE PROBLEM SERVER…

With table that has three fields id, time, and intervention…

If I run this statement, it inserts as expected.

$query = "INSERT INTO data_agreements (`id`, `time`, `intervention`) VALUES (?, ?, ?)";
$q = $pdo->prepare($query);
$q->execute(array("x", "y", "z"));

But if I run the following statement, it fails to insert.

$query = "INSERT INTO data_agreements (`id`, `time`) VALUES (?, ?)";
$q = $pdo->prepare($query);
$q->execute(array("x", "y"));

The problem server is an IIS with MySql 5, PHP 5.2.6. On a different server Apache with MySql 5, PHP 5.2.6, both statements insert as expected. So I am wondering if there is some MySQL install/setting that I need to set on the problem server to tell it to accept statements that specify only a subset of fields in a table. ?

Thanks!

Answer 1

I bet column intervention do not allow null values.

try to alter the table and see if it works:

ALTER table data_agreements Modify intervention varchar(50) null DEFAULT '';

and try to execute again the query. I assumed that intervention is string but, of course, you can modify it that fits your needs.

Thanks.
