问题 The IBM Technote "How to translate the unique identifier as displayed within FileNet Enterprise Manager so that it matches what is stored in the Oracle and DB2 databases" outlines how DB2 & Oracle store guids in a byte reversed order. How can I convert them into a friendly guid? 回答1: Presuming that object_id is char(16) for bit data , the following expression returns the same. '{'||translate( 'GHEFCDAB-KLIJ-OPMN-QRST-UVWXYZ012345' , hex(F.object_id) , 'ABCDEFGHIJKLMNOPQRSTUVWXYZ012345')||'}'

如果宁静是Oracle，那万茜，张雨绮，黄圣依 是什么？

和姐姐们浪起来~ 嗯！这两天在看乘风破浪的姐姐（被逼） =_= 。。。好吧，其实我自己也看进去了。于是就有这样一个奇思妙想，如果把姐姐们比作计算机领域的 技术 or 工具，会是怎么样？于是自己就 yy 了一番。 宁静：Oracle，宁静以致远，江湖地位犹在。在大型企业里，通常拥有庞大的资金能力，所以它们会选择用钱购买解决方案，而不是自己雇佣人员使用 MySQL 去维护。在姐姐中，每人都有一个采访视频。主持人问现在圈内艺人分为一线，二线和三线，你觉得自己是几线？这个问题很犀利，大多数人可能会谦虚一番，宁静直言：我一直是一线。将静姐比作 oracle，当仁不让。 张雨绮：PHP，宇宙第一强无敌，舍我其谁。袁隆平曾经感慨：我这辈子最大的遗憾，就是让你们吃饱了撑着。于是，由于 PHP 入门门槛低，上手快，被吃瓜群众公认为语言界的 TOP1。而我们绮绮子，就更牛逼了，整个一个铁憨憨。 不过其实呢，绮绮子傻大姐，这次真的改变了我之前对其的印象（额，不对，我好像之前都没印象，毕竟我不咋看综艺）。虽说智商偶尔不在线，但她自己给自己创造一个世界，内心清晰而明朗。如同 PHP，内里乾坤，我自知。 万茜：Python，姐姐们的团宠。在一堆美女中，她像个帅气的男孩子，让每个姐姐感觉不到压力和竞争。不管你司是传统开发，大数据，又或者机器学习。嗯，你都会需要我。总而言之 “业务能力很强”。 万茜在开始表演时

I have a .NET console project where I use Oracle.ManagedDataAccess.Client to go through every row in TABLE . TABLE has 500,000 entries and its size is around 300MB.

Update values on one table from another table when criteria is met

问题 I would like to update one table in my db depending on a value from another table.
