## Go Connector
TDengine提供了GO驱动程序“taosSql”包。taosSql驱动包是基于GO的“database/sql/driver”接口的实现。用户可在安装后的/usr/local/taos/connector/go目录获得GO的客户端驱动程序。用户需将驱动包/usr/local/taos/connector/go/src/taosSql目录拷贝到应用程序工程的src目录下。然后在应用程序中导入驱动包,就可以使用“database/sql”中定义的接口访问TDengine:
#### 安装TDengine
Go的链接器使用了到了 libtaos.so 和taos.h,因此,在使用Go连接器之前,需要在程序运行的机器上安装TDengine以获得相关的驱动文件。
#### Go语言引入package
TDengine提供了GO驱动程序“taosSql”包。taosSql驱动包是基于GO的“database/sql/driver”接口的实现。用户可以通过
`go get`
命令来获取驱动包。
```
sh
go get github.com/taosdata/TDengine/src/connector/go/src/taosSql
```
然后在应用程序中导入驱动包,就可以使用“database/sql”中定义的接口访问TDengine:
```
Go
import (
"database/sql"
_ "taosSql"
_ "
github.com/taosdata/TDengine/src/connector/go/src/
taosSql"
)
```
taosSql驱动包内采用cgo模式,调用了TDengine的C/C++同步接口,与TDengine进行交互,因此,在数据库操作执行完成之前,客户端应用将处于阻塞状态。单个数据库连接,在同一时刻只能有一个线程调用API。客户应用可以建立多个连接,进行多线程的数据写入或查询处理。
更多使用的细节,请参考下载目录中的示例源码。
#### Go语言使用参考
在Go程序中使用TDengine写入方法大致可以分为以下几步
1.
打开TDengine数据库链接
首先需要调用sql包中的Open方法,打开数据库,并获得db对象
```
go
db
,
err
:=
sql
.
Open
(
taosDriverName
,
dbuser
+
":"
+
dbpassword
+
"@/tcp("
+
daemonUrl
+
")/"
+
dbname
)
if
err
!=
nil
{
log
.
Fatalf
(
"Open database error: %s
\n
"
,
err
)
}
defer
db
.
Close
()
```
其中参数为
-
taosDataname: 涛思数据库的名称,其值为字符串"taosSql"
-
dbuser和dbpassword: 链接TDengine的用户名和密码,缺省为root和taosdata,类型为字符串
-
daemonUrl: 为TDengine的地址,其形式为
`ip address:port`
形式,port填写缺省值0即可。例如:"116.118.24.71:0"
-
dbname:TDengine中的database名称,通过
`create database`
创建的数据库。如果为空则在后续的写入和查询操作必须通过”数据库名.超级表名或表名“的方式指定数据库名
2.
创建数据库
打开TDengine数据库连接后,首选需要创建数据库。基本用法和直接在TDengine客户端shell下一样,通过create database + 数据库名的方法来创建。
```
go
db
,
err
:=
sql
.
Open
(
taosDriverName
,
dbuser
+
":"
+
dbpassword
+
"@/tcp("
+
daemonUrl
+
")/"
)
if
err
!=
nil
{
log
.
Fatalf
(
"Open database error: %s
\n
"
,
err
)
}
defer
db
.
Close
()
//准备创建数据库语句
sqlcmd
:=
fmt
.
Sprintf
(
"create database if not exists %s"
,
dbname
)
//执行语句并检查错误
_
,
err
=
db
.
Exec
(
sqlcmd
)
if
err
!=
nil
{
log
.
Fatalf
(
"Create database error: %s
\n
"
,
err
)
}
```
3.
创建表、写入和查询数据
在创建好了数据库后,就可以开始创建表和写入查询数据了。这些操作的基本思路都是首先组装SQL语句,然后调用db.Exec执行,并检查错误信息和执行相应的处理。可以参考上面的样例代码
