This library add support for SAP HANA to knex.js. It uses node-hdb as driver.

npm install --save knex-hdb

Please read the knex documentation.

Passing a custom client class to knex doesn't work. You need to instantiate the client manually and use the makeknex utility.

const makeKnex = require('knex/lib/util/make-knex');
const HDBClient = require('knex-hdb');

const client = new HDBClient({
  connection: {
    host     : 'hostname',
    port     : 30015,
    user     : 'user',
    password : 'secret',
    schema   : 'schema'
  }
});

const knex = makeKnex(client);

The custom tableType option may be used to specify the table type.

An increments column will translate to a DEFAULT TO IDENTITY statement. This is only available for 'COLUMN' tables, not for 'ROW' type tables.

Pass 'utf-8' to a string column to create an NVARCHAR column instead a VARCHAR.

knex.schema.createTable('accounts', function(table) {
  table.string('id', 32).primary();
  table.string('account_name');
  table.string('full_name', 255, 'utf-8');
  table.index('account_name');
})

To build this project from source, download it from GitHub and then run

npm install
npm run build

There will be a new 'lib' folder.
