The idea behind throwing an exception is that in this case, it wouldn't have worked previously anyways, so we're just making the error more explicit. Need to double-check that before merging.

@eisberg I forgot about it. Thank you for the reminder.

This is a valid code example that works on 2.9 and a build from this PR:

$stmt = $conn->prepare('SELECT :p FROM DUAL');
$stmt->bindValue('p', 'foo');
$stmt->execute();
echo $stmt->fetchColumn(), PHP_EOL;
// foo

This is an example of invalid code that is not supposed to work:

$stmt = $conn->prepare('SELECT :p FROM DUAL');
$stmt->bindValue(1, 'foo');
$stmt->execute();
echo $stmt->fetchColumn(), PHP_EOL;

On 2.9 it produces:

Warning: oci_bind_by_name(): ORA-01036: illegal variable name/number in lib/Doctrine/DBAL/Driver/OCI8/OCI8Statement.php on line 287
Uncaught Doctrine\DBAL\Driver\OCI8\OCI8Exception: ORA-01008: not all variables bound

On a build from this patch it produces:

Uncaught Doctrine\DBAL\Driver\OCI8\OCI8Exception: Could not find variable mapping with index 1, in the SQL statement

Which is perfectly fine. DBAL prevents a knowingly invalid operation on the underlying driver.

/cc @beberlei (#3779).
