Struct AttachDatabaseStatement 

pub struct AttachDatabaseStatement { /* private fields */ }

Available on crate feature database and non-WebAssembly only.

ATTACH DATABASE statement builder (SQLite-specific)

This struct provides a fluent API for constructing ATTACH DATABASE queries. ATTACH DATABASE allows attaching additional database files to the current connection.

Examples

use reinhardt_query::prelude::*;

// ATTACH DATABASE 'path/to/db.sqlite' AS auxiliary
let query = Query::attach_database()
    .file_path("path/to/db.sqlite")
    .as_name("auxiliary");

Implementations

impl AttachDatabaseStatement

pub fn new() -> AttachDatabaseStatement

Create a new ATTACH DATABASE statement

Examples

use reinhardt_query::prelude::*;

let query = Query::attach_database();

pub fn take(&mut self) -> AttachDatabaseStatement

Take the ownership of data in the current AttachDatabaseStatement

pub fn file_path<S>(&mut self, path: S) -> &mut AttachDatabaseStatement

where S: Into<String>,

Set the file path to the database file

Examples

use reinhardt_query::prelude::*;

let query = Query::attach_database()
    .file_path("path/to/db.sqlite");

pub fn as_name<N>(&mut self, name: N) -> &mut AttachDatabaseStatement

where N: IntoIden,

Set the alias name for the attached database

Examples

use reinhardt_query::prelude::*;

let query = Query::attach_database()
    .file_path("path/to/db.sqlite")
    .as_name("auxiliary");
