Trait odbc_api::Parameters

pub unsafe trait Parameters {
    unsafe fn bind_input_parameters(
        &self, 
        stmt: &mut Statement<'_>
    ) -> Result<(), Error>;
}

SQL Parameters used to execute a query.

ODBC allows to place question marks (?) in the statement text as placeholders. For each such placeholder a parameter needs to be bound to the statement before executing it.

Required methods

unsafe fn bind_input_parameters(
    &self,
    stmt: &mut Statement<'_>
) -> Result<(), Error>

Safety

Implementers should take care that the values bound by this method to the statement live at least for the Duration of self. The most straight forward way of achieving this is of course, to bind members.
