Struct odbc::Connection

pub struct Connection<'env> { /* private fields */ }

Expand description

Represents a connection to an ODBC data source

Implementations

impl<'env> Connection<'env>

pub fn is_read_only(&mut self) -> Result<bool>

true if the data source is set to READ ONLY mode, false otherwise.

This characteristic pertains only to the data source itself; it is not characteristic of the driver that enables access to the data source. A driver that is read/write can be used with a data source that is read-only. If a driver is read-only, all of its data sources must be read-only.

pub fn disconnect(self) -> Result<()>

Closes the connection to the data source. If not called explicitly the disconnect will be invoked implicitly by drop()

Trait Implementations

impl<'env> Handle for Connection<'env>

type To = Dbc

unsafe fn handle(&self) -> SQLHDBC

Returns a valid handle to the odbc type.

impl<'env> Handle for Connection<'env>

const HANDLE_TYPE: HandleType = ffi::SQL_HANDLE_DBC

Used to identify the type of the handle in various functions of the ODBC C interface

fn handle(&self) -> SQLHANDLE

Returns a ptr to the wrapped ODBC Object
