JDBC-CRUD | Java Database Connectivity ] Project that performs CRUD | DB Client library

Currently working on a React/Typescript/Firebase Firestore project. When writing Jest-tests for some actions/functions that are called from the UI, I ran into the following problem:

In the test file I'm able to setup the firestore client using the v9 api and make it talk to emulator

I'm currently building a reactive app using kotlin quarkus and mutiny, being new to reactive programming i wonder what's the best way to handle the following workflow :

• try to find an item in the database (dynamodb)
• if it exists return a value indicating this to the caller
• if it does not exists call the save service
• call an external service to get some data
• update the item in database with those data from the external service
• return a value indicating that the object has been created

Here's my code for now :

_Managed WP, GoDaddy _Tools available: in GD: "File Browser", "phpMyAdmin" (takes me to a URL UI). _phpMyAdmin:

• Has things like "Databases" "Status" "Ex/Import" "Variables" "Charsets" "Engines".
• Left tab has info_schema & server/site id in a drop down menu setup. One drop per item (schema & site/server). Two hierarchies.
• A console/terminal

• db client libmysql - mysqlnd 7.4.16

• I don't know how to control the webserver. I am trying to setup multisite network. Currently testing/configuring pretty permalinks. Instructions unclear. Can't find GoDaddy docs on server interaction. Console in phpMyAdmin only sends SQL queries, totally not helpful. This documentation assumes I am big-brain Dev.
• states

However, we can set our really cool permalink configuration directly by editing Nginx. We will use try_files directive so WordPress can start using pretty permalinks. Let’s see the configuration for WordPress installed on the root of your domain, and also on a directory called /blog

Search for the location / block inside nginx configuration and add the following line inside:

I want to check first if the email exists then check the password but I only want to use PHP and MongoDB not any other language or tool because I'm just a beginner.

when I enter an input the page change to an empty page and nothing happen. I know my error is from the line of the array $findemail and downward.

am I using the $cursor in the right way and if so am I accessing the $findemail in the right way using $d['email'] to compare it with $email

Working with mongocxx I am trying to retrieve the object id assigned by mongodb when I insert a new object in a collection(insert_one method), and convert this id into a string. This is the code:

I have an application module that installs a DynamoDB module

Im trying to write a simple run_transaction function for the Rust MongoDB Driver

This function tries to execute a transaction through the mongo db client and retries the transaction if it encounters a retryable error

Here is a minimum reproducible example of the function.

I have a MySQL database with German "Umlaute öäü" in a table and I need to write a Go app that reads the table, encode it to ISO-8859-1 and write it to a text file.

So far so good, but the encoding to iso-8859-1 is not working. I have tried to debug this.

Here some details and information:

MySQL The MySQL database is UTF8, also the table itself. Also other character sets should be fine, except the character_set_server, but I think this is not relevant here, it should be just a default for new databases as far as I know.

When I query the database with the following SQL, I get the correct UTF8 encoded text:

DynamoDB has multiple nodes and all nodes are equal: there is no single leader. I am assuming we have a DynamoDB instance and all the data can be stored on a single node. But we have several replicas for availability and redundancy.

So writing and reading can happen on any replica node. I am just curious, how DynamoDB client decides to which node the request should be sent? Or the application developer has to take care of this routing themselves and the DyanmoDB client simply forwards these requests to the DB node.

If someone could explain to me where this routing happens and could point me to the code where this routing is implemented, that would be a great help?

I am new to the DynamoDB and trying to understand how things work.
