Sqlx Rust Axum

To create SQLx migrations for PostgreSQL via the terminal, follow these steps:

1. First, install the SQLx CLI if you haven't already:

```bash
cargo install sqlx-cli
```

2. Set up your database URL as an environment variable:

```bash
export DATABASE_URL=postgres://username:password@localhost:5432/your_database
```

3. Create a new migration:

```bash
sqlx migrate add create_notes_table
```

This will create a new directory called `migrations` if it doesn't exist, and within it, two files with timestamps and the name you provided:
- `TIMESTAMP_create_notes_table.up.sql` (for applying the migration)
- `TIMESTAMP_create_notes_table.down.sql` (for reverting the migration)

4. Edit the `.up.sql` file to add your SQL for creating the table:

```bash
cd migrations
nano TIMESTAMP_create_notes_table.up.sql
```

Add your SQL:
```sql
CREATE TABLE IF NOT EXISTS notes (
    id SERIAL PRIMARY KEY,
    title VARCHAR(255) UNIQUE NOT NULL,
    content TEXT NOT NULL,
    categeory VARCHAR(100),
    created_at TIMESTAMPTZ DEFAULT CURRENT_TIMESTAMP
);
```

5. Edit the `.down.sql` file to add SQL for reverting the change:

```bash
nano TIMESTAMP_create_notes_table.down.sql
```

Add:
```sql
DROP TABLE IF EXISTS notes;
```

6. Run the migration:

```bash
sqlx migrate run
```

7. To verify the migration succeeded:

```bash
sqlx migrate info
```

This will show you which migrations have been applied.

If you want to revert a migration:

```bash
sqlx migrate revert
```
