Struct odbc_api::parameter::Out

pub struct Out<'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 output parameter only, rather than an input / output parameter.

Example

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

let env = unsafe {
    Environment::new()?
};

let mut conn = env.connect("YourDatabase", "SA", "<YourStrong@Passw0rd>")?;

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

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

Tuple Fields

0: &'a mut T

Trait Implementations

impl<'a, T> Parameter for Out<'a, T> where
    T: Output, 

Mutable references wrapped in Out are bound as output parameters.

unsafe fn bind_parameter(
    self,
    parameter_number: u16,
    stmt: &mut StatementImpl<'_>
) -> Result<(), Error>

Bind the parameter in question to a specific parameter_number.
