Go语言访问mysql数据库需要用到标准库database/sql和mysql的驱动.标准库的Api使用比较繁琐这里再引入另一个库github.com/jmoiron/sqlx. go get github.com/jmoiron/sqlx go get github.com/go-sql-driver/mysql 连接数据库 db, err := sqlx.Connect("mysql", "...?parseTime=true") if err != nil {
同以前一样,先写一个数据库打开和关闭操作类 public class DBConnection { String driver = "com.mysql.jdbc.Driver"; String url= "jdbc:mysql://localhost:3306/test"; String user = "root"; String password = "123456"; public Connection conn; pu
/*所有字段插入值*//*注意插入值数目要与字段值一致*/INSERT INTO student VALUES(1,'熊大','123','2019-10-18',1200);INSERT INTO student VALUES(3,'熊二','123','2019-10-18',1200);/*部分字段插入值*/INSERT INTO student (uid,PASSWORD, money)VALUES(2,'123456',10000);/*修改语句*/UPDATE student SE
