I have some data in Firebase and want to retrieve it. Sometimes it can be null. How do I not get an exception for it?

How to delay a function returning a value before response from database? [duplicate] This question already has an answer here: I have a function which modifies a variable as per response from database. function f () { let x = { }; redis.get ("key1").then ( value => x.prop1 = value); redis.get ("key2").then ( value => x.prop2 = value); return x; } This is my code roughly. It is actually in a for loop, using node-redis. I have multiple calls to Redis. I add the data from Redis to a new object and return the object. PROBLEM: function f () is returning an empty object every time I call it. f () How do I wait for all Redis promises to resolve before returning the object? This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question. 1 Answer 1 In your code, you are not waiting f...

In cassandra if i have table per query and i have multiple combinations of filter, do i create a table for each of them? I am new to NoSQL and i was trying to get my head around how to model data correctly for an e-commerce site. Amazon has these filters for different type of products, for example if you search for laptops, there are filters like brand, processor, hard disk, graphics card, os and etc. So by what i understand, first the primary key will be partitioned by browse node id (i.e. laptop here), then we can have additional keys as sort key, but the problem is that if there are 6 filters there will be around 64 combinations that can be formed. I can select brand and processor, or maybe brand and graphics card, or maybe processor and graphics card, and this will be exponential with the number of filters, so i assume having a table for each possibility is not feasible. I also doubt that filtering after getting the whole partition data is possible, that would be too slow. So how s...

Electron app with database I'm creating a web app for ticket reservation. The only problem is the database. I don't want to tell my client to install XAMPP or set a database, etc. Is there any way to package the app with the database? sqlite might be an option – David784 Jun 30 at 23:21 1 Answer 1 SQLite is a good option for a local database that you can ship with your application. It won't require the user to setup or install any extra dependencies. It's certainly not as full featured as a full on server, but it should be good enough for a local desktop app. By clicking "Post Your Answer", you acknowledge that you have read our updated terms of service, privacy policy and cookie polic...

Recipe / Bill of Materials MySQL Query I am writing a Bill of Materials/Recipe App for Minecraft in Node.js, Express, React and MySQL.

Example Required Output in Table format or JSON format: INGREDIENT || QTY || TYPE Pis...

Cannot connect to password encrypted MS Access 2016 database using C# When I try to connect to a MS Access 2016 database, it connects perfectly without password, but when I try to connect to the same database after encrypting it with a password, I get this error: Cannot open the database. It may not be a database that your application recognizes, or the file may be corrupt. I don't know what I should do - my database isn't corrupted, and I have to make it with a password.

Copying specific tables of a MySQL database to a MariaDB database in JDBC I am trying to create a Java programm that copies specific tables from a MySQL database on one server to a MariaDB on another. I know there is mysqldump but the purpose of the program is to be running on different machines, even if they don't habe mysql installed. What I created seems to work well, as the resulting SQL does look correct and executes for example when I connect to the MariaDB with HeidiSQL. But when I execute the sql using .executeQuery , I get an error as response that there is a problem with my SQL. .executeQuery The code is basically: import java.sql.* public class JdbcTest { Connection conn = null; Connection conn_2 = null; Statement stmt = null; Statement stmt_2 = null; //MySQL Class.forName("com.mysql.cj.jdbc.Driver"); //MariaDB Class.forName("org.mariadb.jdbc.Driver"); System.o...
