在运行SELECT语句时，Date列中的空白值返回为1900/01/01（在select语句中用）

在运行SELECT语句时，Date列中的空白值返回为1900/01/01（在select语句中用）

[PAYOFF DATE]列具有一些空白值和一些以mm / dd / yy格式表示的值。

我必须将“ /”替换为“-”，并将日期返回为yyyy-mm-dd。下面的查询正在执行此操作。问题是对于所有空白值，我得到的结果都是1900-01-01。

是否可以将1900-01-01替换为null并按yyyy-mm-dd格式返回其他有效日期值？

我正在使用SQL Server。

SELECTcast(replace(a.[PAYOFF DATE],''/'',''-'') as date) FROM MTG a

答案1

小编典典

您不需要像问题中所示的那样进行字符串操作。如果日期以mm/dd/yyyy格式存储，则将其强制转换为DATE。

SELECT cast(a.[PAYOFF DATE] AS DATE) FROM MTG a

对于1900-01-01值，由于您是从字符串数据类型转换为日期，因此字符串数据类型可以具有空字符串，但是日期数据类型不能具有空日期值，它可以具有日期值或NULL值。

因此，您需要先将空字符串转换为null，然后再将其转换为日期。1900-01-01只是sql server为您输入的默认值，因为Date数据类型不能有空值。

您可以通过执行以下操作避免使用此sql server默认值。

SELECT cast(NULLIF(a.[PAYOFF DATE],'''') AS DATE) FROM MTG a

0x80190001是一个登录账号出现的错误代码，很多用户的应用市场相对就使用不了了，主要是Intelnet的设置问题，今天小编就给大家轻松解决问题的方法。

0x80190001是什么错误

是代理导致的错误。

第一种方法：

1、在Internet Explorer浏览器的右上角点击设置，打开“Internet选项”。

2、在“Internet选项”界面，进入“常规”，单击“删除”，再点击“确定”，缓存文件就已经全部删除。

3、在“Internet选项”界面，进入“高级”， 单击 “重置”，即可。

按Windows+R输入services.msc找到Microsoft Account Sign-in Assistant右键启动是否正常。

第二张方法：

检查是Internet选项 - 连接 - 局域网（LAN）设置 - 使用自动配置脚本影响导致。把勾去掉后就可以登录账户了，这个是ss生成的自动配置脚本，不知道为什么会影响Windows商店登录。

hibernate select语句返回的类型

hibernate select语句返回的类型

Person类中包含有MyEvent这个类 

public class Person{
   private Long id;
   private String name;
   private MyEvent myEvent;
}

一、HQL from语句 

1、结果类型：List<Person>

from Person  或者 from Person as p
from Person as p where p.myEvent.title = :title
注意：hibernate3.2.3之前总是对的。 
   hibernate3.2.3之后如果myEvent是普通属性或关联的实体也是对的，如果myEvent是一个集合会出异常 
   因此hibernate推荐使用下面的方式：

select p from Person as p inner join p.myEvent as e where e.title = :title

2、结果类型 List<Person,Event>

from Person as p inner join p.myEvent as event where event.title = : title
注：查询出来是：是一个集合，集合元素是Person,myEvent组成的数组。 
   结果类型： List<Person,Event> 

from Person as p left outer join p.myEvent as event where event.title = : title

注意：查询出来是：是一个集合，集合元素是Person,myEvent组成的数组。 
           结果类型： List<Person,Event>

from Person as p right outer join p.myEvent as event where event.title = : title
from Person as p full join p.myEvent as event where event.title = : title

第二：HQL select语句 

1、结果类型:  List<String> 

select p.name from Person as p

2、结果类型：List<Object[String,Person]>

select p.name,p from Person as p

3、结果类型：List<String,String>

select new List(p.name,p.address) from Person as p

4、结果类型：List<ClassTest>

select new ClassTest(p.name,p.address) from Person as p

   注意：前提ClassTest 类有两个参数的构造器。 

5、结果类型：List<map<String,String>>

select new map(p.name as personName) from Person as p

 

java.text.ParseException：不可parsingdate：“1901-01-01 00:00:00”

java.text.ParseException：不可parsingdate：“1901-01-01 00:00:00”

这段代码在Windows中正常工作，但在Linux中引发java.text.ParseException：

DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss",new Locale("es","ES")); df.setLenient(false); Date date = df.parse("1901-01-01 00:00:00"); System.out.println(date);

Windows输出：

Tue Jan 01 00:00:00 CET 1901

Linux输出：

Exception in thread "main" java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.simontuffs.onejar.Boot.run(Boot.java:340) at com.simontuffs.onejar.Boot.main(Boot.java:166) Caused by: java.text.ParseException: Unparseable date: "1901-01-01 00:00:00" at java.text.DateFormat.parse(DateFormat.java:357) ...

如果删除df.setLenient(false)行，则Windows输出是相同的，并且Linuxexception消失，但是Linux输出似乎不正确：

Tue Jan 01 00:14:44 CET 1901

有人知道发生了什么吗？

谢谢

组态：

Windows：Win7 + jdk1.7.0_71

Linux：Ubuntu + jdk1.7.0_60

编辑：作为anolsi说是夏令时问题。 有了date“2015-03-29 02:00:01”，在Windows和Linux中抛出了parsingexception，因为这个date在马德里不存在（时间从马德里的凌晨2:00到凌晨3:00那天）。 所以正确的行为是Linux的一个。 Windows JDK应该抛出exception。

这应该与您正在使用的区域设置/时区定义有关。

正如你可以检查下http://www.timeanddate.com/time/change/spain/madrid?year=1901该时区不存在特定的时间，因为夏令时（DST）&#x3002; 这应该是造成不一致的地方。

如果您尝试1901-02-01 00:00:00 ，例如，它应该工作正常。

编辑1：允许更改和控制时区的示例。

import java.text.SimpleDateFormat; import java.text.DateFormat; import java.util.Locale; import java.util.TimeZone; import java.util.Date; public class MainClass { public static void main(String[] args) { try { DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss","ES")); df.setTimeZone(TimeZone.getTimeZone("Europe/Madrid")); df.setLenient(false); Date date = df.parse("1901-01-01 00:00:00"); System.out.println(date); } catch(Exception ex){ ex.printstacktrace(); } } }

编辑2：请看看关于时区和偏移的好文章： https : //stackoverflow.com/tags/timezone/info

关于在运行SELECT语句时，Date列中的空白值返回为1900/01/01和在select语句中用的介绍现已完结，谢谢您的耐心阅读，如果想了解更多关于0x80190001是什么错误_0x80190001账号登录解决教程、APPLE-SA-2019-3-25-2 macOS Mojave 10.14.4,Security Update 2019-002 High Sierra, Security Update 2...、hibernate select语句返回的类型、java.text.ParseException：不可parsingdate：“1901-01-01 00:00:00”的相关知识，请在本站寻找。
