Install:
	yum install unixODBC unixODBC-devel

认真阅读微软官方的安装文档照着安装，否则很多地雷：

官方下载包中有两个sh文件：build_dm.sh，install.sh。按照sh文件的提示进行安装即可。

Install:
	wget http://download.microsoft.com/download/B/C/D/BCDD264C-7517-4B7D-8159-C99FC5535680/RedHat6/msodbcsql-11.0.2270.0.tar.gz
	tar xvf msodbcsql-11.0.2270.0.tar.gz	
	cd msodbcsql-11.0.2270.0
	./build_dm.sh
	//build_dm.sh会下载依赖包，然后会出现如下提示叫你安装相应的依赖。
	//Run the command 'cd /tmp/unixODBC.4745.28125.26522/unixODBC-2.3.0; make install' to install the driver manager.
	./install.sh verify	//验证安装条件是否满足，主要是检查依赖是否解决。
	./install.sh install

安装成功后，查看文件/etc/odbcinst.ini，发现新增了如下内容：

[ODBC Driver 11 for SQL Server]
	Description=Microsoft ODBC Driver 11 for SQL Server
	Driver=/opt/microsoft/msodbcsql/lib64/libmsodbcsql-11.0.so.2270.0
	Threading=1
	UsageCount=1

证明SQL Server Driver安装成功了。

参考文档：http://www.easysoft.com/products/data_access/odbc-sql-server-driver/getting-started.html#data-source

vi /etc/odbc.ini添加如下代码：

[SQLSERVER_SAMPLE]
	Driver          = ODBC Driver 11 for SQL Server
	Description     = ODBC Driver 11 for SQL Server
	Server          = 192.168.1.1
	Port            =
	Database        = database
	User            = root
	Password        = root

Install:
	cd $GOPATH/src
	git clone git://github.com/weigj/go-odbc.git odbc
	cd odbc
	go install
	cd odbc/driver
	go install

odbc.go:18:17: error: sql.h: No such file or directory
	odbc.go:19:20: error: sqlext.h: No such file or directory
	odbc.go:20:22: error: sqltypes.h: No such file or directory

package main;

import (
        "fmt"
        "database/sql"
        _"odbc/driver"
)

func main(){
        conn,err := sql.Open("odbc","DSN=SQLSERVER_SAMPLE;driver={ODBC Driver 11 for SQL Server};SERVER=192.168.1.235;UID=sa;PWD=zgj_1234;DATABASE=gameupdate");

        if(err!=nil){
                fmt.Println("Connecting Error");
                return;
        }
        defer conn.Close();
        stmt,err := conn.Prepare("select top 5 id from users_role");
        if(err!=nil){
                fmt.Println("Query Error",err);
                return;
        }
        defer stmt.Close();
        row,err := stmt.Query();
        if err!=nil {
                fmt.Println("Query Error",err);
                return;
        }
        defer row.Close();
        for row.Next() {
                var id int;
                if err := row.Scan(&id);err==nil {
                        fmt.Println(id);
                }
        }
        fmt.Printf("%s\n","finish");
        return;
}

在执行上面的go代码中，如果出现错误：

Query Error IM002 [unixODBC][Driver Manager]Data source name not found, and no default driver specified

可能是SQL Server Driver没有安装成功，或者DSN没有配置。关键还是在于需要对ODBC有一定了解，才不会犯低级错误。
