使用Go连接MySQL

go get code.google.com/p/go-mysql-driver/mysql  

package main  
  
import "fmt"  
import "database/sql"  
import "code.google.com/p/go-mysql-driver/mysql"  
  
func main(){  
    fmt.Printf("query:\n")  
    db,e  := sql.Open("mysql", "root:@/mysql?charset=utf8")  
    //说明：第一个参数"mysql"表示打开一个MYSQL链接  
    //第二个参数是一个DSN，格式是：  
    //[username[:password]@][protocol[(address)]]/dbname[?param1=value1&paramN=valueN]  
  
    if e != nil {  
        fmt.Printf("conn error.");  
        return;  
    }  
    rows,e := db.Query("select host,user from user")  
    if e != nil {  
        fmt.Printf("query error.");  
        return;  
    }  
  
    i := 0  
    for rows.Next() {  
        i++  
        var ss,s2 string  
        e = rows.Scan( &ss,&s2 )  
        if e == nil {  
            fmt.Printf("Title: %s,%s \n", ss,s2 )  
        }else{  
            fmt.Printf("error")  
        }  
    }  
    fmt.Printf("Total: %d\n" , i )  
    db.Close()  
  
}
