Simplify basic usage (hide Thrift details)

[arikfr]

Current basic usage example:

const driver = require('databricks-sql-node');
const { TCLIService, TCLIService_types } = driver.thrift;
const client = new driver.DBSQLClient(
 TCLIService,
 TCLIService_types
);

client.connect({
 host: '********.databricks.com',
 path: '/sql/1.0/endpoints/****************',
 token: 'dapi********************************',
}).then(async client => {
 const session = await client.openSession();
 const response = await session.getInfo(
 TCLIService_types.TGetInfoType.CLI_DBMS_VER
 );

 console.log(response.getValue());

 await session.close();
}).catch(error => {
 console.log(error);
});

Let's simplify it to be:

const driver = require('databricks-sql-node');
const client = new driver.DBSQLClient();

await client.connect({
 host: '********.databricks.com',
 path: '/sql/1.0/endpoints/****************',
 token: 'dapi********************************',
});

const session = await client.openSession();
const response = await session.executeStatement("SELECT 1");

// TODO: probably need to change the following
console.log(response.getValue());

await session.close();
