get()

static get(path): default

get

A static initializer which synchronously returns an instance of the Database class while deferring the actual database connection until the first invocation or selection on the database.

Returns

default

Example

const db = Database.get("sqlite:test.db");

Source: undefined

load()

static load(path): Promise<default>

load

A static initializer which connects to the underlying database and returns a Database instance once a connection to the database is established.

Sqlite

The path is relative to tauri::path::BaseDirectory::App and must start with sqlite:.

Parameters

Interfaces

QueryResult

Properties

Property	Type	Description	Defined in
lastInsertId?	number	The last inserted id. This value is not set for Postgres databases. If the last inserted id is required on Postgres, the select function must be used, with a RETURNING clause (INSERT INTO todos (title) VALUES ($1) RETURNING id).	Source: undefined
rowsAffected	number	The number of rows affected by the query.	Source: undefined
