SQL Studio
SQL Studio allows you to visually design your database, and also execute any SQL towards your database of choice. SQL Studio also allows you to export the result of some SQL to a CSV file, in addition to saving frequently used SQL statements by using the “Snippets” and “Save” buttons.
If you install one of the SQLite database plugins using the plugins component, you also typically get a lot of example SQL statements - Implying SQL Studio is also a nice place to start out if you want to teach yourself SQL. To access the SQL editor open up SQL Studio and click “SQL view”.
Create and design your database visually
You can also use SQL Studio to visually create and design your database. This is a graphical user interface, where you don’t need to write any SQL DDL to create your database structure. SQL Studio’s database designer allows you to create new tables, add fields to your tables, and create foreign keys referencing other tables as you wish. In addition SQL Studio’s designer also allows you to create “link tables”, automatically encapsulating a many to many relationship between two tables.
SQL Studio features
The “Safe mode” slider prevents you from selecting more than 200 records from your database in one go. If you need to select more records you must turn this slider off. However, if you return thousands of records with some SQL statement, your server might become unresponsive, and/or you may end up exhausting your server’s memory.
You can save your frequently used SQL statements as “snippets” similarly to how you can save frequently used Hyperlambda in the Hyperlambda Playground component. This allows you to store frequently used SQL snippets for later, creating a library of snippets you can tap into later as you need to execute the same SQL later.
SQL Studio also provides you with autocomplete on both your tables and columns. This typically works best of you write SQL statements where your tables are aliased, and you write the alias of your table, followed by a dot (.), for then to trigger autocomplete. To launch autocomplete click FN+CONTROL+SPACE on a Mac, or CTRL+SPACE on Windows.
In addition, you can import SQL statements from your local development machine by clicking the “Import” button, which will bring up a browse for file dialogue, allowing you to import some SQL file from your local machine into the SQL editor surface of SQL Studio.
SQL Studio and Machine Learning
SQL Studio integrates with the machine learning and AI parts of Magic. This allows you to ask SQL related questions, such as; “Create an SQLite DDL for me that creates a users and roles table, where each user is referencing a role with a foreign key”.
The AI features of SQL Studio doesn’t always produce perfect code, but it is built on top of OpenAI’s APIs, so it should be good enough to give you at least an approximation of what you want to achieve. Notice, you need an API key with OpenAI to have these parts of SQL Studio work.
If you use the AI chat interface in SQL Studio you can ask the AI to create, and/or modify your code, and such have “conversations” with the AI about your code.
SQL Studio designer features
The SQL Studio database designer allows you to do the following things.
- Create new tables
- Create new fields
- Create new foreign keys
- Create many to many link tables automatically
- Export one table’s DDL
- Export all tables’ DDL
- Automatically create migration scripts
SQL Studio doesn’t give you every single feature of SQL DDL, but it’s good enough to provide you with 90% of what you need as you are designing your database schema. When you create a new foreign key for instance, it will ask you if you want to allow for null values in your foreign keys, and if you wants to turn on cascading deletes - But it will not ask you if you want to set to null upon deletions.
For a walkthrough of SQL Studio’s most important features you can watch the following YouTube video.
Exporting your DDL to a module
When you are exporting your table(s)’ DDL, you can also optionally export your DDL to a “module”. This is useful if you are creating plugins or similar functionality using Magic, since it will automatically wire up everything required to automatically create your database if it doesn’t exist on whatever cloudlet you install your module on - In addition to sequentially executing all migrate scripts associated with your module.
This implies that if you create a reusable module or plugin, once your plugin is installed, it will automatically create its database, and execute all SQL migration scripts as it is installed or updated.
SQL Studio’s designer works transparently towards all database types, implying you can use it to create databases for MySQL, PostgreSQL, SQLite, MariaDB, and SQL Server. However, what types of fields you can create differs between database types.
Auto migrations
If you turn on “Auto migrate” by clicking the triple dots icon in design view, and turn on auto migrate, SQL Studio will ask you if you want to apply auto migration as you change your database DDL. This functionality will automatically create the required files to apply automatic migration as you’re editing your database.
This is useful if you’re editing a reusable module you want to install on other cloudlets somehow, since if the module is (re)-installed it will run through each of your migration scripts, and automatically change your database structure.
How to create a database using SQL Studio
You cannot actually create a database with SQL Studio. This needs to be done using the Databases menu item below the “Create” section. However, once you have created a database, you can use SQL Studio to create tables in it, and modify it as you need.
