psql returns 'anonymous' in results array - sql

I'm running the following psql on my node server:
SELECT json_data.key AS id, json_data.value::int AS version
FROM players.settings, json_each_text(players.settings.value) AS json_data
WHERE name = $1 AND json_data.value::int > 0;
The results returned include the string anonymous before each result object:
[ anonymous { id: '1ab56bd6-ef7d-4755-92d5-1b0cf7beb4b7', version: 1 },
anonymous { id: '4ea3d884-d2a6-4074-a094-a45f6003e6d4', version: 1 } ]
What am I missing here? I've never seen this anonymous string before and would like to get rid of it.

To my knowledge, you can't get rid of it, at least not on your side.
See: https://github.com/brianc/node-postgres/issues/1062
It's just a Node.js 6 new feature to report into the console when the object was created using an anonymous class.
You can safely ignore it ;)

How to use select_object_content via rusoto / rust?

The following code tries to select some data from a file stored on S3:
let client = S3Client::new(Region::default());
let source = ... object providing bucket and key ...;
let r = SelectObjectContentRequest {
bucket: source.bucket,
key: source.key,
expression: "select id from S3Object[*].id".to_string(),
expression_type: "SQL".to_string(),
input_serialization: InputSerialization {
json: Some(JSONInput { type_: Some("LINES".to_string()) }),
..Default::default()
},
output_serialization: OutputSerialization {
json: Some(JSONOutput { record_delimiter: Some("\n".to_string()) }),
..Default::default()
},
..Default::default()
};
It causes the following error:
The specified method is not allowed against this
resource.POST
The example is a 1:1 port of a working Python/boto3 example, so I'm quite sure it should work. I found this issue, which is a few month old and the status is not clear to me. How do I get this working with Rust?
Unfortunately s3 select still doesn't work on the latest rusoto_s3-0.40.0. The issue you linked has all the answer. The problems are twofold.
First, right now the s3 select request rusoto sends out has a bogus query string. It should be /ObjectName?select&select-type=2, but rusoto encodes it to be /bjectName?select%26select-type=2. That's the error you saw.
To verify, run your project like so:
$ RUST_LOG=rusoto,hyper=debug cargo run
You will see logs from rusoto and hyper. Sure enough it emits an incorrect URI. One can even dig into the code responsible:
let mut params = Params::new();
params.put("select&select-type", "2");
request.set_params(params);
It is supposed to be:
let mut params = Params::new();
params.put("select-type", "2");
params.put("select", "");
request.set_params(params);
Although the fix seems trivial, remember these are glue code generated from AWS botocore service manifests, not manually coded. To incorporate the fix is not that straightforward.
Second, the bigger problem. The AWS s3 select response uses a customized binary format. rusoto simply doesn't have a deserializer for that yet.

How get raw SQL from sequelize migraions

I have a bunch of Sequilize migration files. All looks like:
module.exports = {
up: //up migration
down: //down migration,
};
Is there a programmatically way to get SQL queries from that files? It will be ok to use Node ecosystem. The only requirement do that automatically.
Why do I want do this?
I wan't to create SQL migrations from javascript files to put them into entrypoint of my Postgres base image for local development. And I don't want to put Node.js with Sequelize into my image which depends only on Postgres official base image from Docker Hub.
If you already have a database with the right schema, all you need is the schema. You can use pg_dump command to get the schema
pg_dump.exe -U username -d databasename -s schemaname> myschema.sql
You can now import this schema
psql -d database_name -h localhost -U postgres < myschema.sql
I know you're asking how to get this programatically but just exposing the raw SQL is valuable. I was able to get the raw sql (sorting this out led me to this question) by adding the key logging to the options object.
This is my migration:
await queryInterface.addIndex(
constants.EVENTS_TABLE_NAME,
['created_at'],
{ using: 'brin', concurrently: true, logging: console.log }
);
and the output from the migration:
== 20220311183756-create-brin-index-on-created-at: migrating =======
Executing (default): CREATE INDEX CONCURRENTLY "events_created_at" ON "events" USING brin ("created_at")
== 20220311183756-create-brin-index-on-created-at: migrated (0.019s)
Here is an example from their docs:
await sequelize.query('SELECT 1', {
// A function (or false) for logging your queries
// Will get called for every SQL query that gets sent
// to the server.
logging: console.log,
// If plain is true, then sequelize will only return the first
// record of the result set. In case of false it will return all records.
plain: false,
// Set this to true if you don't have a model definition for your query.
raw: false,
// The type of query you are executing. The query type affects how results are formatted before they are passed back.
type: QueryTypes.SELECT
});

Is it possible to retrieve the namespace of a raised error?

When I raise an error from within an XQuery query, for instance with:
error( fn:QName( 'http://example.com', 'XMPL0001' ), 'Conflict' )
... the following is returned by BaseX (be it when communicating with the server, or from within the GUI)
Stopped at ., 1/7:
[XMPL0001] Conflict
Is it somehow possible to retrieve the namespace of the error (in this case http://example.com) as well?
I'm using a customized PHP client and I would like to use this information to prevent possible (future) conflicts with my custom error codes and parse the errors to throw either a standard BaseX\Exception or a custom SomeNamespace\Exception, depending on the namespace of the error.
I could, of course, simply use another error code pattern than the typical ABCD1234 XQuery pattern, to prevent possible (future) error code conflicts, but the possible use of a namespace appeals to me more, because I can then define an uniform Exception interface, such as:
interface ExceptionInterface
{
public function getCategory(); // the 4 alpha character part
public function getCode(); // the 4 digit part
}
I'm currently using BaseX 7.7.2, by the way.
Yes, you can retrieve information about the error using a few variables in the error namespace, which are in scope of the try-catch statement, like so:
declare namespace err = "http://www.w3.org/2005/xqt-errors";
try {
error( fn:QName( 'http://example.com', 'XMPL0001' ), 'Conflict' )
}
catch * {
namespace-uri-from-QName($err:code)
}
This assumes that you are using XQuery 3.0.

Knowledge & Connect PHP API, Found object(Account or Answer) but contains only null fields

I'm facing some strange issues when I try to fetch(Connect PHP API)/searchContent(Knowledge Foundation API) following the tutorials/documentations.
Behaviour and output
Following the documentation, we initialize the API. The function error_get_last() (called after the fetch) states that the core read-only file (we are not allowed to modify it) contains an error:
Array ( [type] => 8 [message] => Undefined index: REDIRECT_URL [file] => /cgi-bin/${interface_name}.cfg/scripts/cp/core/framework/3.2.4/init.php [line] => 246 )
After initialization, we call the fetch function to retrieve an account. If we give a wrong ID, it returns an error:
Invalid ID: No such Account with ID = 32
Otherwise, furnishing a correct ID returns an Account object with all fields populated as NULL:
object(RightNow\Connect\v1_2\Account)#22 (25) {
["ID"]=>
NULL
["LookupName"]=>
NULL
["CreatedTime"]=>
NULL
["UpdatedTime"]=>
NULL
["AccountHierarchy"]=>
NULL
["Attributes"]=>
NULL
["Country"]=>
NULL
["CustomFields"]=>
NULL
["DisplayName"]=>
NULL
["DisplayOrder"]=>
NULL
["EmailNotification"]=>
NULL
["Emails"]=>
NULL
["Login"]=>
NULL
/* [...] */
["StaffGroup"]=>
NULL
}
Attempts, workaround and troubleshooting information
Configuration: The account used using the InitConnectAPI() has the permissions
Initialization: Call to InitConnectAPI() not throwing any exception(added a try - catch block)
Call to the fetch function: As said above, the call to RNCPHP\Account::fetch($act_id) finds the account (invalid_id => error) but doesn't manage to populate the fields
No exception is thrown on the RNCPHP::fetch($correct_id) call
The behaviour is the same when I try to retrieve an answer following a sample example from the Knowledge Foundation API : $token = \RNCK::StartInteraction(...) ; \RNCK::searchContent($token, 'lorem ipsum');
Using PHP's SoapClient, I manage to retrieve populated objects. However, It's not part of the standard and a self-call-local-WebService is not a good practice.
Code reproducing the issue
error_reporting(E_ALL);
require_once(get_cfg_var('doc_root') . '/include/ConnectPHP/Connect_init.phph');
InitConnectAPI();
use RightNow\Connect\v1_2 as RNCPHP;
/* [...] */
try
{
$fetched_acct = RNCPHP\Account::fetch($correct_usr_id);
} catch ( \Exception $e)
{
echo ($e->getMessage());
}
// Dump part
echo ("<pre>");
var_dump($fetched_acct);
echo ("</pre>");
// The core's error on which I have no control
print_r(error_get_last());
Questions:
Have any of you face the same issue ? What is the workaround/fix which would help me solve it ?
According to the RNCPHP\Account::fetch($correct_usr_id) function behaviour, we can surmise that the issue comes from the 'fields populating' step which might be part of the core (on which I have no power). How am I supposed to deal with this (fetch is static and account doesn't seem abstract) ?
I tried to use the debug_backtrace() function in order to have some visibility on what may go wrong but it doesn't output relevant information. Is there any way I can get more debug information ?
Thanks in advance,
Oracle Service Cloud uses lazy loading to populate the object variables from queried data using Connect for PHP APIs. When you output the result of an object, it will appear as each variable is empty, per your example. However, if you access the parameter, then it becomes available. This is only an issue when you try to print your object, like this example. Accessing the data should be immediate.
To print your object, like in your example, you would need to iterate through the object variables and access each one first. You could build a helper class to do that through reflection. But, to illustrate with a single field, do the following:
$acct = RNCPHP\Account::fetch($correctId);
$acct->ID;
print_r($acct); // Will now "show" ID, but none of the other fields have been loaded.
In the real world, you probably just want to operate on the data. So, even though you cannot "see" the data in the object, it's there. In the example below, we're accessing the updated time of the account and then performing an action on the object if it meets a condition.
//Set to disabled if last updated < 90 days ago
$acct = RNCPHP\Account::fetch($correctId);
$chkDate = time() - 7776000;
if($acct->UpdatedTime < $chkDate){
$acct->Attributes->PermanentlyDisabled = true;
$acct->save(RNCPHP\RNObject::SuppressAll);
}
If you were to print_r the object after the if condition, then you would see the UpdatedTime variable data because it was loaded at the condition check.

DB2 SQL connection in Protractor - How To

I am new to Protractor and still learning. In my conf.js file I have (maybe incorrectly?) set up a connection to a database:
mysql = require('C:/.../AppData/Roaming/npm/node_modules/mysql');
var connection = mysql.createConnection({
host : 'localhost',
user : 'username',
password : 'password',
database : '//xxxxxxx.xxx.xx:nnnnn/xxxxxxxx'
});
connection.connect();
Then in my test I attempt to query for data to use:
//SQL to get Random Invoice Ref
var invRef = SELECT foo FROM table.table
WHERE condition = myData
ORDER BY RAND()
FETCH FIRST ROW ONLY;
But, it's giving me this error:
invRef = SELECT foo FROM table.table ('foo' is underlined with the '^' character)
Exception loading: C:\...\testSpec.js
Error -- fail
I suspect I have things set up incorrectly, to say the least. Can someone tell me the proper way to define a db2 SQL connection in Protractor? Am I also using it correctly in my test?
Just missing some double quotes there:
//SQL to get Random Invoice Ref
var invRef = "SELECT foo FROM table.table " +
"WHERE condition = myData " +
"ORDER BY RAND() " +
"FETCH FIRST ROW ONLY;";
Given you're setting up SQL access from Protractor NodeJS side of things to load test data from there to fill up forms for example.
Side note: Doc on Protractor components will help you separate concerns.
UPDATE
DB2 SQL in NodeJS
Install IBM client from here. Match your server version.
Use a NodeJS DB2 library like this one.
