Trait odbc_api::ParameterCollection

pub unsafe trait ParameterCollection {
    fn parameter_set_size(&self) -> u32;
    unsafe fn bind_parameters_to(
        &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

fn parameter_set_size(&self) -> u32

Number of parameters in the collection. This can be different from the maximum batch size a buffer may be able to hold. Returning 0 will cause the the query not to be executed.

unsafe fn bind_parameters_to(
    &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.
