include-oracle-sql is an extension of include-sql for using Oracle SQL in Rust. It completes include-sql by providing impl_sql macro to generate database access methods from the included SQL. include-oracle-sql uses Sibyl 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:

-- 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 book records to reflect loan to a patron
-- # Parameters
-- param: user_id: &str - user ID
-- param: book_ids: usize - book IDs
UPDATE library
   SET loaned_to = :user_id
     , loaned_on = current_timestamp
 WHERE book_id IN (:book_ids);

And then use it in Rust as:

use include_oracle_sql::{include_sql, impl_sql};
use sibyl as oracle;

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

fn main() -> oracle::Result<()> {
    let db_name = std::env::var("DBNAME").expect("database name");
    let db_user = std::env::var("DBUSER").expect("user name");
    let db_pass = std::env::var("DBPASS").expect("password");
    let user_id = std::env::var("USERID").expect("library user ID");

    let oracle = oracle::env()?;
    let session = oracle.connect(&db_name, &db_user, &db_pass)?;

    session.get_loaned_books(user_id, |row| {
        let book_title : &str = row.get("BOOK_TITLE")?;
        println!("{}", book_title);
        Ok(())
    })?;

    Ok(())
}
