For the official SAP HANA client Go support (not this database driver) please see [SAP Help Portal](https://help.sap.com/viewer/0eec0d68141541d1b07893a39944924e/2.0.02/en-US/0ffbe86c9d9f44338441829c6bee15e6.html).

## Installation

```
go get github.com/SAP/go-hdb/driver
```

## Building

To build go-hdb you need to have a working Go environment with [version 1.11.5 or higher installed](https://golang.org/dl/).

## Documentation

API documentation and documented examples can be found at <https://godoc.org/github.com/SAP/go-hdb/driver>.

## Tests

To run the driver tests a HANA Database server is required. The test user must have privileges to create database schemas.

```
go test -dsn hdb://user:password@host:port
```
