Struct odbc_api::parameter::InOut

pub struct InOut<'a, T>(pub &'a mut T);

Wraps a mutable reference. Use this wrapper in order to indicate that a mutable reference should be bound as an input / output parameter.

Example

use odbc_api::{Environment, Out, InOut, Nullable};

let env = Environment::new()?;

let mut conn = env.connect("YourDatabase", "SA", "My@Test@Password1")?;

let mut ret = Nullable::<i32>::null();
let mut param = Nullable::new(7);

conn.execute(
    "{? = call TestParam(?)}",
    (Out(&mut ret), InOut(&mut param)))?;
