How to create a custom table in Supabase?

 

Step 1:   Set Up Your Supabase Project  

1. Create an Account and Sign In:
   Navigate to Supabase and create an account if you don't already have one, or sign in to your existing account.

2. Create a New Project:
   Once logged in, click on 'New Project' to create a new Supabase project. Provide a project name, select a database password, and choose the server region closest to you. Click 'Create New Project' to proceed.

 

Step 2:   Access the Database Page  

1. Navigate to the Database Section:
   After your project is created, you'll be directed to the Project Overview page. On the left sidebar, click on 'Database' to access the database management section.

 

Step 3:   Open SQL Editor  

1. Launch the SQL Editor:
   Within the database section, go to 'SQL Editor'. Here, you'll be able to write and execute SQL commands to interact with your database.

 

Step 4:   Write the SQL to Create a Custom Table  

1. Define Your Table Schema:
   Decide on the structure of the table you need. The table schema involves choosing the table name, along with column names and their respective data types.

2. SQL Command for Creating a Table:
   Use the following SQL template to create your custom table:

   ```sql
   CREATE TABLE custom_table_name (
   id SERIAL PRIMARY KEY,
   column1_name data_type1,
   column2_name data_type2,
   column3_name data_type3
   );
   ```

   Replace custom_table_name with the name of your table and column1_name, column2_name, etc., with your desired column names and their associated data types (e.g., VARCHAR, INTEGER, TEXT). id SERIAL PRIMARY KEY is a common setup for auto-incrementing unique identifier columns.

 

Step 5:   Execute the SQL Command  

1. Run the SQL Command:
   Once your SQL is prepared in the SQL editor, click 'Run' or 'Execute' to run the SQL command. This will create your table in the database if your SQL syntax is correct.

2. Check for Confirmation or Errors:
   After execution, your SQL command's status (success or error) will appear in the console. Verify if the table is created successfully or debug errors if there are any issues with the SQL syntax.

 

Step 6:   Verify Table Creation  

1. Go Back to the Database Section:
   Navigate back to the database section and look for your new table under the 'Tables' section to ensure it has been created.

2. Double-check Table Schema:
   Open the table details to verify the table's schema matches what you specified in your SQL command.

 

Step 7:   Manage and Use Your Table  

1. Insert Data into Your Table:
   Use SQL commands to insert data into your new table and begin utilizing it for your application's needs. Examples of SQL INSERT commands can be found in Supabase documentation or general SQL resources.

2. Set Up Row Level Security and Policies:
   To secure your data, ensure to establish appropriate Row Level Security (RLS) rules and policies for your table via Supabase's intuitive settings if necessary.

Now you have successfully created and set up a custom table in Supabase!
