第二章:测试环境
① 测试 sql 语句
形式如下面的语句以及在此基础上的嵌套
sql
语句:
insert into org_xxx (a, b, c, ...) values (a1, b1, c1, ...);
commit;
delete from org_xxx where code = 'xxx';
commit;
update org_xxx set name = "xxx" where code = 'xxx';
commit;
② 测试代码块
外部调用下面的代码来执行。
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
public class DBUpdate {
public static int getRs(Connection conn, String sql) {
/*
作用:插入、更新、删除数据库
返回:影响的行数:0代表无影响
*/
Statement st = null;
int rs = 0;
try {
// statement对象用于执行sql语句
st = conn.createStatement();
// 执行sql语句,成功返回修改行数,不成功返回0
rs = st.executeUpdate(sql);
}catch(SQLException e){
e.printStackTrace();
}catch (Exception e){
e.printStackTrace();
}
return rs;
}
}
③ 测试驱动和 JDK 版本
由于有些驱动没有现成的数据库,未进行测试,如:
mysql
、高斯。
喜欢的点个赞❤吧!
javascript object转化成strig javascript object转string
Object显示类型转换(强制类型转换)ECMAScript中可用的3种强制类型转换如下:Boolean(value)把给定的值转换成Boolean型;String(value)把给定的值转换成字符串。Number(value)把给定的值转换成数字(可以是整数或浮点数);Object类型到Boolean类型// 除了空引用(null)会转换为false,其他都被转换为true
var obj =
