i have the following code...

// start

        $db = &ADONewConnection('postgres');
        $db ->
Connect($db_string,$db_owner,$db_pw,$db_name);
//        $db -> debug=true;

        $customer_name =
$form->GetInputValue('customer_name');
        $customer_id = $db->getone("select
nextval('t_customer_cust_id_seq')");

$sql_insert = <<<_EOSQL

    INSERT INTO t_customer (customer_id,
customer_name, customer_entry_date)
    VALUES (?,?,?)

_EOSQL;

        $result = $db->Execute($sql_insert,
array($customer_id, $customer_name,
$db->DBDate(time())));

//end code

it produces the following error...

ERROR: column "customer_id" is of type integer but
expression is of type boolean HINT: You will need to
rewrite or cast the expression.

any ideas?

the answer is...  boolean.

Charley, i'm not sure.  this code worked before i
upgraded both pgsql.  at least i'm pretty darn sure it
did.  then again, maybe i've lost my mind.  having
said that, i don't see anything in the code that says
"boolean" to me.

i will try and cast it is an integer and let the adodb
maintainer know about this issue.

using php to cast to to an integer...

$customer_id = (int) $customer_id;

...worked for me.  i have a note in on the adodb forum
to find out why it is casting as boolean.

What's the value of $customer_id before you attempt the insert?

right after $customer_id variable is set, do the following:

echo $customer_id . '<br />';
echo gettype ( $customer_id );
exit;

With ADO, a couple of times, I've run into a glitch where bindings
changed types.  Haven't taken the time to figure out why.  Switching
to autoExecute solves the problem:

$insert_array = array ( 'customer_id' => $db->getone("select nextval
('t_customer_cust_id_seq')"),
                    'customer_name' => $form->GetInputValue('customer_name'),
                    'customer_entry_date' => $db->DBDate(time()))

$result = $db->autoExecute ( 't_customer',
                            $insert_array,
                            'INSERT' );

Most likely, the reason it works for me is that I cleaned up my error
when switching to the autoExecute method.

I think your query failed.

After you execute this query:

>> $customer_id = $db->getone("select nextval
>> ('t_customer_cust_id_seq')");

do the following:

echo $db->ErrorMsg();
exit;

That will tell you why the query failed.

it says...

ERROR: relation "t_customer_cust_id_seq" does not
exist

i'm off to hunt down the actual name of the sequence.

bottom line - if you get a boolean response, check to
see if the query has failed first.

thank you for the insight.

Quite a few functions in php do this. If you use the
syntax == or != it is C-style compare. That is, zero
is false and basically the rest is true.

If you use === or !== it evaluates to true if both
the types are equal AND the statement is true.

So, the correct syntax would be

if (false === ($customer_id = $db->getone("..."))) {
     error handling.
}

Example from the manual:
// in PHP 4.0b3 and newer:
$pos = strrpos($mystring, "b");
if ($pos === false) { // note: three equal signs
     // not found...
}

By doing this, strrpos can return 0 (not an error) or
false (not found). Without === strrpos would have to
return -1 or some other illegal position for not found.
