Replicate Tables Schema In Supabase
Introduction
As we embark on a new project, it's essential to replicate the existing tables schema from our old project to ensure a seamless transition. In this article, we will explore how to replicate the tables schema in Supabase, a powerful cloud-based database platform. We will cover the tables schema and their relations, and provide a PR with the schema file to generate all the tables with the correct relations.
Tables Schema and Relations
Before we dive into replicating the tables schema in Supabase, let's take a look at the existing tables schema and their relations.
Users Table
The users table refers to the patients. This table stores information about each patient, including their personal details and therapy progress.

| created_at | timestamp | Timestamp when the patient's account was created |
| updated_at | timestamp | Timestamp when the patient's account was last updated |
Therapist Table
The therapist table refers to the therapists. This table stores information about each therapist, including their personal details and qualifications.

| created_at | timestamp | Timestamp when the session was created |
| updated_at | timestamp | Timestamp when the session was last updated |
Therapy Goal Table
The therapy_goal table refers to the therapy goals section of the app. This table stores information about each goal, including its details and progress.
| Column Name | Data Type | Description |
|---|---|---|
| id | integer | Unique identifier for each goal |
| session_id | integer | Foreign key referencing the sessions table |
| goal_name | varchar | Name of the therapy goal |
| goal_description | text | Description of the therapy goal |
| created_at | timestamp | Timestamp when the goal was created |
| updated_at | timestamp | Timestamp when the goal was last updated |
Replicating Tables Schema in Supabase
To replicate the tables schema in Supabase, we need to create a schema file that defines the tables and their relations. Here is an example of a schema file that replicates the tables schema:
CREATE TABLE users (
id SERIAL PRIMARY KEY,
name VARCHAR(255) NOT NULL,
email VARCHAR(255) NOT NULL,
phone VARCHAR(255) NOT NULL,
created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);
CREATE TABLE therapists (
id SERIAL PRIMARY KEY,
name VARCHAR(255) NOT NULL,
email VARCHAR(255) NOT NULL,
phone VARCHAR(255) NOT NULL,
qualifications TEXT NOT NULL,
created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);
CREATE TABLE packages (
id SERIAL PRIMARY KEY,
name VARCHAR(255) NOT NULL,
description TEXT NOT NULL,
price DECIMAL(10, 2) NOT NULL,
created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);
CREATE TABLE sessions (
id SERIAL PRIMARY KEY,
patient_id INTEGER NOT NULL REFERENCES users(id),
therapist_id INTEGER NOT NULL REFERENCES therapists(id),
package_id INTEGER NOT NULL REFERENCES packages(id),
session_date DATE NOT NULL,
session_time TIME NOT NULL,
created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);
CREATE TABLE therapy_goals (
id SERIAL PRIMARY KEY,
session_id INTEGER NOT NULL REFERENCES sessions(id),
goal_name VARCHAR(255) NOT NULL,
goal_description TEXT NOT NULL,
created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);
This schema file defines the tables and their relations, including the foreign keys that reference the users, therapists, and packages tables.
Conclusion
In this article, we explored how to replicate the tables schema in Supabase. We covered the tables schema and their relations, and provided a PR with the schema file to generate all the tables with the correct relations. By replicating the tables schema in Supabase, we can ensure a seamless transition to the new project and maintain the existing data and relationships.

Replicate Tables Schema in Supabase: Q&A =====================================
Introduction
In our previous article, we explored how to replicate the tables schema in Supabase. We covered the tables schema and their relations, and provided a PR with the schema file to generate all the tables with the correct relations. In this article, we will answer some frequently asked questions (FAQs) about replicating tables schema in Supabase.
Q: What is the purpose of replicating tables schema in Supabase?
A: The purpose of replicating tables schema in Supabase is to ensure a seamless transition to the new project and maintain the existing data and relationships. By replicating the tables schema, we can ensure that the new project has the same structure and relationships as the old project.
Q: How do I create a schema file in Supabase?
A: To create a schema file in Supabase, you can use the Supabase console or the Supabase CLI. The Supabase console allows you to create a new schema file by clicking on the "Schema" tab and then clicking on the "Create Schema" button. The Supabase CLI allows you to create a new schema file by running the supabase schema create command.
Q: What is the difference between a schema file and a database file?
A: A schema file is a file that defines the structure of a database, including the tables, columns, and relationships. A database file, on the other hand, is a file that contains the actual data in the database. In Supabase, the schema file is used to define the structure of the database, and the database file is used to store the actual data.
Q: How do I add a foreign key constraint to a table in Supabase?
A: To add a foreign key constraint to a table in Supabase, you can use the ALTER TABLE statement with the ADD CONSTRAINT clause. For example, to add a foreign key constraint to the sessions table that references the users table, you can use the following statement:
ALTER TABLE sessions
ADD CONSTRAINT fk_sessions_users
FOREIGN KEY (patient_id)
REFERENCES users (id);
Q: How do I drop a table in Supabase?
A: To drop a table in Supabase, you can use the DROP TABLE statement. For example, to drop the therapy_goals table, you can use the following statement:
DROP TABLE therapy_goals;
Q: How do I rename a table in Supabase?
A: To rename a table in Supabase, you can use the RENAME TABLE statement. For example, to rename the therapy_goals table to therapy_sessions, you can use the following statement:
RENAME TABLE therapy_goals TO therapy_sessions;
Q: How do I create a view in Supabase?
A: To create a view in Supabase, you can use the CREATE VIEW statement. For example, to create a view that combines the sessions and therapy_goals tables, you can use the following statement:
CREATE VIEW therapy_sessions AS
SELECT *
FROM sessions
JOIN therapy_goals ON sessions.id = therapy_goals.session_id;
Conclusion
In this article, we answered some frequently asked questions (FAQs) about replicating tables schema in Supabase. We covered topics such as creating a schema file, adding foreign key constraints, dropping tables, renaming tables, and creating views. By understanding these concepts, you can effectively replicate tables schema in Supabase and maintain the existing data and relationships.
