Linux + Golang + Oracle 11g + XORM + go-oci8 的数据库驱动测试

一、系统环境介绍：

Linux archlinux 4.20.11-arch1-1-ARCH
Oracle 11g 64bit
OCI -> instantclient-basic-linux.x64-11.2.0.4.0.zip
OCI SDK -> instantclient-sdk-linux.x64-11.2.0.4.0.zip
go version go1.11 linux/amd64

二、安装pkg-config

# pacman -S pkg-config

三、安装go-oci8

项目开源地址：https://github.com/wendal/go-oci8

四、下载Oracle 的 OCI和SDK

1、下载OCI和SDK

https://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

下载下面两文件:
instantclient-basic-linux.x64-11.2.0.4.0.zip
instantclient-sdk-linux.x64-11.2.0.4.0.zip

• 将上面的两个压缩文件解压到/usr/instantclient_11_2中，/usr/instantclient_11_2文件夹中内容如下：
  adrci genezi libnnz11.so libociei.so ojdbc5.jar sdk xstreams.jar
  BASIC_README libclntsh.so.11.1 libocci.so.11.1 libocijdbc11.so ojdbc6.jar uidrvci

• 设置环境变量LD_LIBRARY_PATH:
  LD_LIBRARY_PATH=:/usr/instantclient_11_2

五、编辑oci8.pc,配置环境变量PKG_CONFIG_PATH

• 创建oci8.pc文件,放在项目地址如/home/go/src/test/oracle/oci8.pc, 编辑oci8.pc内容如下,确保oracle库文件及头文件地址正确:

prefix=/usr
includedir=${prefix}/instantclient_11_2/sdk/include
libdir=${prefix}/instantclient_11_2

Name: oci8
Description: Oracle Instant Client
Version: 11.2
Cflags: -I${includedir}
Libs: -L${libdir} -lclntsh

• 设置环境变量
  PKG_CONFIG_PATH=/home/go/src/test/oracle

六、数据操作测试

测试文件main_test.go，测试前注意先添加userinfo表及数据

package main_test

import (
    "database/sql"
    "testing"

    "github.com/go-xorm/xorm"
    _ "github.com/mattn/go-oci8"
)

var driverName = "oci8" //Oracle 驱动
var dataSourceName = "ggs/123456@127.0.0.1:1521/ORCL"  //数据库账号：ggs，密码：123456，实例服务：ORCL
var engine *xorm.Engine

func TestXormOracle(t *testing.T) {
    var err error
    engine, err = xorm.NewEngine(driverName, dataSourceName)
    if err != nil {
        t.Error(err)
    }
    tabs, err := engine.DBMetas()
    if err != nil {
        t.Error(err)
    }
    println(len(tabs)) 
}

func TestMattnOracle(t *testing.T) {
    var db *sql.DB
    var err error
    if db, err = sql.Open(driverName, dataSourceName); err != nil {
        t.Error(err)
        return
    }
    var rows *sql.Rows
    if rows, err = db.Query("select * from userinfo"); err != nil {
        t.Error(err)
        return
    }
    defer rows.Close()
    for rows.Next() {
        var id int
        var name string
        rows.Scan(&id, &name)
        println(id, name) // 3.14 foo
    }
}
