通过Php脚本查询Oracle数据库：特权不足

Question

I'm trying to query a remote Oracle database through a PHP script. I'm running WAMP server. The Oracle database is read only. I have no problem connecting using the PHP script but I get errors on the oci_execute command.

This is the script I use:

<?php

$c = oci_connect("username", "password", "oracle_SID");

if (!$c) {
$e = oci_error();
trigger_error('Could not connect to database: '. $e['message'],E_USER_ERROR);
}

$s = oci_parse($c, 'Select * from fdma.t_title_stage');
if (!$s) {
    $e = oci_error($c);
    trigger_error('Could not parse statement: '. $e['message'], E_USER_ERROR);
}

$r = oci_execute($s);
if (!$r) {
$e = oci_error($s);
trigger_error('Could not execute statement: '. $e['message'], E_USER_ERROR);
}

oci_free_statement($stid);
oci_close($conn);

?>

These are the errors I'm getting when I run the script:

If the database is read-only I should be able to run a select * query against it, right?

Oracle has no concept of a database being "read-only". The user you're connecting with may not have any create/insert/update/delete rights, which would make the database read-only to this user, but it's a property of the user, not the database.

The error you're getting, in conjunction with the sql statement ( ... from fdma.t_title_stage ) seems like you're connecting with a user that doesn't even have select rights on fdma's t_title_stage table. Try loggin in as fdma , the grant select on t_title_stage to xxx with xxx being the username you're using in your oci_connect statement.
