Oracle 10g accepting 5 digit year in a Date

由 风流意气都作罢 提交于 2021-02-02 09:55:13
问题 I managed to enter the date 21-Feb-12017 (I know it's not a correct date) in Oracle 10g into a date column. Oracle accepted the date fine. When I tried to select it back in SQL Developer, SQL Developer displayed it as NULL. But when I tried to retrieve the date thru java, I got the value back as how I inserted. Wondering what's going on because I could also see that Oracle converted a different 5 digit year into a 4 digit year. I entered 21-Feb-21019 and Oracle converted the year to 4581

How to represent Oracle Interval in Java

由 …衆ロ難τιáo~ 提交于 2021-02-02 09:15:27
问题 I'm using Java 7 with hibernate 4. Want to use oracle Interval data type (http://psoug.org/definition/INTERVAL.htm) to represent a interval of a certain number of days. Wondering what Java Type to use to map this Oracle Interval Object. I would like to use standard Java objects and not any oracle.sql.* objects as mentioned in this document http://docs.oracle.com/cd/B28359_01/java.111/b31224/datacc.htm. Here's the table I'm playing with: CREATE TABLE "MyTest" ( "ID" NUMBER(14,0) NOT NULL

服务端 ：oracle 11g 客户端 ： pl/sql 问题描述 ： 用客户端 pl/sql 连接登录的时候，提示 "ORA-12514: TNS: no listener"。 在服务器用 telnet localhost 1521 和 telnet 127.0.0.1 1521 都可以，但是 telnet IP 1251 不行。 解决方案 ： 将服务端的 \product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora 的 (ADDRESS = (PROTOCOL = TCP)(HOST =127.0.0.1)(PORT = 1521)) 改为： (ADDRESS = (PROTOCOL = TCP)(HOST =计算机名)(PORT = 1521)) 然后重启 11gClientListener 服务 https://www.cnblogs.com/heige/p/3544762.html 来源： oschina 链接： https://my.oschina.net/u/4323130/blog/4238974

PageHelper分页插件的原理是什么

由 前提是你 提交于 2021-02-02 04:43:07
作者：祖大俊 原文： https: / /my.oschina.net/zudajun /blog/ 745232 PageHelper是一款好用的开源免费的Mybatis第三方物理分页插件，其实我并不想加上好用两个字，但是为了表扬插件作者开源免费的崇高精神，我毫不犹豫的加上了好用一词作为赞美。 原本以为分页插件，应该是很简单的，然而PageHelper比我想象的要复杂许多，它做的很强大，也很彻底，强大到使用者可能并不需要这么多功能，彻底到一参可以两用。但是，我认为，作为分页插件，完成物理分页任务是根本，其它的很多智能并不是必要的，保持它够傻够憨，专业术语叫stupid，简单就是美。 我们将简单介绍PageHelper的基本使用和配置参数的含义，重点分析PageHelper作为Mybatis分页插件的实现原理。 1. PageHelper的maven依赖及插件配置 < dependency > < groupId > com.github.pagehelper </ groupId > < artifactId > pagehelper </ artifactId > < version > 4.1.6 </ version > </ dependency > PageHelper除了本身的jar包外，它还依赖了一个叫jsqlparser的jar包，使用时
