Struct EnvInterceptor

pub struct EnvInterceptor { /* private fields */ }

Read environment variables and fill them in query.

Example

-- SQLNESS ENV SECRET
SELECT $SECRET;

Environment variables declared in ENV interceptor will be replaced in the going to be executed. It won’t be rendered in the result file so you can safely put secret things in your query.

Note that only decalred and present environment variables will be replaced.

You can either declare multiple env in one intercetor or separate them into different interceptors. The following two examples are equivalent:

-- SQLNESS ENV SECRET1 SECRET2
SELECT $SECRET1, $SECRET2;

-- SQLNESS ENV SECRET1
-- SQLNESS ENV SECRET2
SELECT $SECRET1, $SECRET2;
