# 数据库连接

## 示例

开发人员可以自行创建数据库连接：

```go
package main

import (
	"database/sql"
	_ "github.com/mattn/go-sqlite3"
)

func main() {	
	db, err := sql.Open("sqlite3", "./test.db")
	if err == nil {
		defer db.Close()
	}
	//...
}
```

或者使用属性文件创建：

```go
package main

import (
	"github.com/doytowin/goooqo/rdb"
	_ "github.com/mattn/go-sqlite3"
)

func main() {
	db := rdb.Connect("app.properties")
	defer rdb.Disconnect(db)
	//...
}
```

## 属性格式

属性文件包含不同数据库的参数，模版如下：

```properties
driver=sqlite3
data_source=./test.db

#driver=mysql
#mysql_url=tcp(localhost:3306)/demo?charset=utf8mb4&parseTime=true
#mysql_database=demo
#mysql_username=root
#mysql_password=root
```

将会在`Dialect`功能上线后，提供更多属性配置。

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://goooqo.docs.doyto.win/zh/api/connection.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
