GO字符格式化问题

[指剑对天笑]

我又来了，下面代码
str := "select * from tbl where id= ? and name =?"
arg := make([]interface{},2)
arg = append(arg,"1")
arg= append(arg,"张三")

我想输出 select * from tbl where id= 1 and name =张三 请问大哥们怎么实现呢？

for example

package main

import (
	"fmt"
	"strings"
)

func main () {
	str := "select * from tbl  where id= ? and name =?"
	arg := make([]interface{},2)
	arg[0] = "1"
	arg[1] = "张三"
	for _, v := range arg {
		str = strings.Replace(str, "?", fmt.Sprintf("%v", v), 1) //字符串替换就可以了
	}
	fmt.Println(str)
}
