dbc

dbc is the command-line tool for installing and managing ADBC drivers.

Install

import { AdbcDatabase } from '@apache-arrow/adbc-driver-manager'

const db = new AdbcDatabase({
  driver: 'snowflake',
  databaseOptions: {
    username: 'USER',
    password: 'PASS',
    'adbc.snowflake.sql.auth_type': 'auth_snowflake',
    'adbc.snowflake.sql.account': 'ACCOUNT-IDENT',
  },
})

let conn
try {
  conn = await db.connect()
  const table = await conn.query('SELECT * FROM CUSTOMER LIMIT 5')
  console.log(table.toString())
} finally {
  await conn?.close()
  await db.close()
}
