**include-sqlite-sql** is an extension of [include-sql][1] for using SQLite SQL in Rust. It completes include-sql by providing `impl_sql` macro to generate database access methods from the included SQL. include-sqlite-sql uses [Rusqlite][2] for database access.

# Example

Write your SQL and save it in a file. For example, let's say the following is saved as `library.sql` in the project's `src` folder:

```sql
-- name: get_loaned_books ?
--
-- Returns the list of books loaned to a patron
--
-- # Parameters
--
-- param: user_id: &str - user ID
--
SELECT book_title
  FROM library
 WHERE loaned_to = :user_id
 ORDER BY 1

-- name: loan_books!
--
-- Updates the book records to reflect loan to a patron
--
-- # Parameters
--
-- param: book_titles: &str - book titles
-- param: user_id: &str - user ID
--
UPDATE library
   SET loaned_to = :user_id
     , loaned_on = current_timestamp
 WHERE book_title IN (:book_titles)
```

And then use it in Rust as:

```rust , ignore
use include_sqlite_sql::{include_sql, impl_sql};
use rusqlite::{Result, Connection};

include_sql!("src/library.sql");

fn main() -> Result<()> {
    let db = Connection::open("library.db")?;

    db.loan_books(&["War and Peace", "Gone With the Wind"], "Sheldon Cooper")?;

    db.get_loaned_books("Sheldon Cooper", |row| {
        let book_title : &str = row.get_ref(0)?.as_str()?;
        println!("{book_title}");
        Ok(())
    })?;

    Ok(())
}
```

# Documentation

The included [documentation][3] describes the supported SQL file format and provides additional details on the generated code.

# 💥 Breaking Changes in 0.2

* [include-sql][1] changed optional statement terminator from `;` to `/`. SQL files that used `;` terminator would need to change it to `/` or remove it completely.

# ✨ New Features in 0.2

* [include-sqlite-sql][3] now supports statement [batches][4]. Statement variant selector for this is `&`. See [library.sql][5] for an example of its use.
