在Go语言中使用MySQL的动态条件查询实际上是很简单的。可以使用数据库/ SQL包提供的预处理语句。下面是一个示例代码,以便您快速了解这个过程:

package main

import (
	"database/sql"
	"fmt"

	_ "github.com/go-sql-driver/mysql"
)

func main() {
	// Open database connection
	db, err := sql.Open("mysql", "user:password@tcp(localhost:3306)/dbname")
	if err != nil {
		fmt.Println(err.Error())
		return
	}
	defer db.Close()

	// Prepare statement
	stmt, err := db.Prepare("SELECT name FROM users WHERE age=?")
	if err != nil {
		fmt.Println(err.Error())
		return
	}
	defer stmt.Close()

	// Execute the query
	rows, err := stmt.Query(25)
	if err != nil {
		fmt.Println(err.Error())
		return
	}
	defer rows.Close()

	// Get results
	var name string
	for rows.Next() {
		err := rows.Scan(&name)
		if err != nil {
			fmt.Println(err.Error())
			return
		}
		fmt.Println(name)
	}

	err = rows.Err()
	if err != nil {
		fmt.Println(err.Error())
		return
	}
}
SELECT name FROM users WHERE age=?Query
