GoDoc Reference Build Status

Description

Golang Oracle database driver conforming to the Go database/sql interface

Installation

Install Oracle full client or Instant Client:

https://www.oracle.com/technetwork/database/database-technologies/instant-client/downloads/index.html

Install a C/C++ compiler

Install pkg-config, edit your package config file oci8.pc (examples below), then set environment variable PKG_CONFIG_PATH to oci8.pc file location (Or can use Go tag noPkgConfig then setup environment variables CGO_CFLAGS and CGO_LDFLAGS)

Go get with Go version 1.9 or higher

go get github.com/mattn/go-oci8

Try the simple select example:

https://godoc.org/github.com/mattn/go-oci8#example-package--SqlSelect

If you have a build error it is normaly because of a misconfiguration, make sure to search close issues for help
