How do you manually execute SQL commands in Ruby On Rails using NuoDB

How to Execute SQL Commands in Ruby On Rails Using NuoDB 💎

Are you struggling to manually execute SQL commands in Ruby on Rails using NuoDB? 😕 Don't worry, you're not alone! Many developers face this common issue but luckily, we have some easy solutions for you! Let's dive in and explore how you can execute SQL commands and retrieve the desired data instead of getting a pesky "true" response. 🚀

The Command You Need for SQL Execution 🤔

To manually execute SQL commands in Ruby on Rails using NuoDB, you need to use the following command:

ActiveRecord::Base.connection.execute("SQL query")

Here, the "SQL query" can be any valid SQL command you want to execute. 💪

The Problem: Receiving a "true" Response Instead of Data 🙁

Let's say you have a table called "Feedback" and you want to execute a simple SELECT command to fetch all the data. Here's the command you might use:

ActiveRecord::Base.connection.execute("SELECT `feedbacks`.* FROM `feedbacks`")

However, the output you receive in the Rails Console turns out to be:

SQL (0.4ms)  SELECT `feedbacks`.* FROM `feedbacks`
=> true

Instead of getting the desired data, you end up with a frustrating "true" response. Ugh! 😫

The Solution: Using the Right Method 🚀

To overcome this problem and obtain the requested data, you can simply use the select_all method instead of execute. Here's the modified command:

ActiveRecord::Base.connection.select_all("SELECT `feedbacks`.* FROM `feedbacks`")

By using select_all, you'll get the actual data you're looking for! 🎉

Calling Stored Procedures in NuoDB 👉

Now that you know how to execute SQL commands and retrieve data, let's spice things up and talk about calling stored procedures in NuoDB using Ruby on Rails.

When calling stored procedures, you might encounter the same issue of receiving a "true" response instead of the expected results. The solution here is quite similar to the previous one.

Instead of using the execute method, you need to utilize the select_all method with a slight modification. Here's how it looks:

ActiveRecord::Base.connection.select_all("CALL your_stored_procedure_name(arguments)")

Remember to replace your_stored_procedure_name with the actual procedure name you want to call, and pass any required arguments in place of arguments.

With this approach, you'll be able to execute stored procedures and obtain the desired data without any distractions! 😎
