# snowflake-promise
2+
3+
A Promise-based interface to your [Snowflake](https://www.snowflake.net/) data warehouse.
4+
5+
This is a wrapper for the [Snowflake SDK](https://www.npmjs.com/package/snowflake-sdk) for Node.js. It provides a Promise-based API instead of the core callback-based API.
6+
7+
## Installation
8+
9+
`npm i snowflake-promise`
10+
11+
## Basic usage
12+
13+
```typescript
14+
const Snowflake = require('snowflake-promise').Snowflake;
15+
// or, for TypeScript:
16+
import { Snowflake } from 'snowflake-promise';
17+
18+
async function main() {
19+
const snowflake = new Snowflake({
20+
account: '<account name>',
21+
username: '<username>',
22+
password: '<password>',
23+
database: 'SNOWFLAKE_SAMPLE_DATA',
24+
schema: 'TPCH_SF1',
25+
warehouse: 'DEMO_WH'
26+
});
27+
28+
await snowflake.connect();
29+
30+
const rows = await snowflake.execute(
31+
'SELECT COUNT(*) FROM CUSTOMER WHERE C_MKTSEGMENT=:1',
32+
['AUTOMOBILE']
33+
);
34+
35+
console.log(rows);
36+
}
37+
38+
main();
39+
```
40+
41+
## More examples
42+
43+
* [Streaming result rows](../../examples/streaming.js)
44+
* [Using traditional Promise `then` syntax (and older versions of Node.js)](../../examples/oldSchool.js)
45+
* Node 4.0.0 is the oldest supported version

//
2+
// This example shows how to use the library in traditional Promise style. You
3+
// might do this if you are using an older version of Node that doesn’t support
4+
// async/await, or simply if you prefer the Promise/then syntax.
5+
//
6+
// (You could also transpile async/await code using TypeScript or Babel, which
7+
// allows it to run on older versions of Node.)
8+
//
9+
// This library supports Node 4.0.0 and higher.
10+
//
11+
12+
//
13+
// Use this when processing large datasets (or when retrieving only a few rows
14+
// from a large result set). This is common when doing batch processing.
15+
//
16+
// This avoids loading the entire result set into memory, and lets you work on
17+
// one row at a time.
