跨服务器从一个服务器数据库一张表导数据到另一个服务器数据库另
昨天做项目需要导数据,从server97中的数据库(正式数据库)到数据到server46(测试数据库),平时都是查询出来然后复制到另一张表,由于数据小,没有什么不妥,但是这次由于其中某些表数据量比较大,二十来万条记录,直接复制粘贴,耗费大量IO,二十多分钟
昨天做项目需要导数据,从server97中的数据库(正式数据库)到数据到server46(测试数据库),平时都是查询出来然后复制到另一张表,由于数据小,没有什么不妥,但是这次由于其中某些表数据量比较大,二十来万条记录,直接复制粘贴,耗费大量IO,二十多分钟都没有成功,郁闷不已。本来打算导出到Excel中,再导入数据库,但是Excel一次容不下这么多条数据。
没办法,只好上网查询怎么跨服务器查询导入,最后成功解决问题,二十多万条记录三秒多就导入成功啦,爽歪歪,哈哈!采用的是红色代码,具体办法如下:
用openrowset连接远程SQL或插入数据
--如果只是临时访问,可以直接用openrowset
--查询示例
select * from openrowset('SQLOLEDB', 'sql服务器名'; '用户名'; '密码', 数据库名.dbo.表名)
--导入示例
select * into 表 from openrowset('SQLOLEDB' ,'sql服务器名';'用户名';'密码' ,数据库名.dbo.表名)
--创建链接服务器
exec sp_addlinkedserver 'srv_lnk', '', 'SQLOLEDB','远程服务器名或ip地址'
exec sp_addlinkedsrvlogin 'srv_lnk','false',null,'用户名','密码'
go
--查询示例
select * from srv_lnk.数据库名.dbo.表名
--导入示例
select * into 表 from srv_lnk.数据库名.dbo.表名
--以后不再使用时删除链接服务器
exec sp_dropserver 'srv_lnk','droplogins'
go

Facing lag, slow mobile data connection on iPhone? Typically, the strength of cellular internet on your phone depends on several factors such as region, cellular network type, roaming type, etc. There are some things you can do to get a faster, more reliable cellular Internet connection. Fix 1 – Force Restart iPhone Sometimes, force restarting your device just resets a lot of things, including the cellular connection. Step 1 – Just press the volume up key once and release. Next, press the Volume Down key and release it again. Step 2 – The next part of the process is to hold the button on the right side. Let the iPhone finish restarting. Enable cellular data and check network speed. Check again Fix 2 – Change data mode While 5G offers better network speeds, it works better when the signal is weaker

I cry to death. The world is madly building big models. The data on the Internet is not enough. It is not enough at all. The training model looks like "The Hunger Games", and AI researchers around the world are worrying about how to feed these data voracious eaters. This problem is particularly prominent in multi-modal tasks. At a time when nothing could be done, a start-up team from the Department of Renmin University of China used its own new model to become the first in China to make "model-generated data feed itself" a reality. Moreover, it is a two-pronged approach on the understanding side and the generation side. Both sides can generate high-quality, multi-modal new data and provide data feedback to the model itself. What is a model? Awaker 1.0, a large multi-modal model that just appeared on the Zhongguancun Forum. Who is the team? Sophon engine. Founded by Gao Yizhao, a doctoral student at Renmin University’s Hillhouse School of Artificial Intelligence.

Recently, the military circle has been overwhelmed by the news: US military fighter jets can now complete fully automatic air combat using AI. Yes, just recently, the US military’s AI fighter jet was made public for the first time and the mystery was unveiled. The full name of this fighter is the Variable Stability Simulator Test Aircraft (VISTA). It was personally flown by the Secretary of the US Air Force to simulate a one-on-one air battle. On May 2, U.S. Air Force Secretary Frank Kendall took off in an X-62AVISTA at Edwards Air Force Base. Note that during the one-hour flight, all flight actions were completed autonomously by AI! Kendall said - "For the past few decades, we have been thinking about the unlimited potential of autonomous air-to-air combat, but it has always seemed out of reach." However now,

The latest video of Tesla's robot Optimus is released, and it can already work in the factory. At normal speed, it sorts batteries (Tesla's 4680 batteries) like this: The official also released what it looks like at 20x speed - on a small "workstation", picking and picking and picking: This time it is released One of the highlights of the video is that Optimus completes this work in the factory, completely autonomously, without human intervention throughout the process. And from the perspective of Optimus, it can also pick up and place the crooked battery, focusing on automatic error correction: Regarding Optimus's hand, NVIDIA scientist Jim Fan gave a high evaluation: Optimus's hand is the world's five-fingered robot. One of the most dexterous. Its hands are not only tactile

FP8 and lower floating point quantification precision are no longer the "patent" of H100! Lao Huang wanted everyone to use INT8/INT4, and the Microsoft DeepSpeed team started running FP6 on A100 without official support from NVIDIA. Test results show that the new method TC-FPx's FP6 quantization on A100 is close to or occasionally faster than INT4, and has higher accuracy than the latter. On top of this, there is also end-to-end large model support, which has been open sourced and integrated into deep learning inference frameworks such as DeepSpeed. This result also has an immediate effect on accelerating large models - under this framework, using a single card to run Llama, the throughput is 2.65 times higher than that of dual cards. one

Last week, amid the internal wave of resignations and external criticism, OpenAI was plagued by internal and external troubles: - The infringement of the widow sister sparked global heated discussions - Employees signing "overlord clauses" were exposed one after another - Netizens listed Ultraman's "seven deadly sins" Rumors refuting: According to leaked information and documents obtained by Vox, OpenAI’s senior leadership, including Altman, was well aware of these equity recovery provisions and signed off on them. In addition, there is a serious and urgent issue facing OpenAI - AI safety. The recent departures of five security-related employees, including two of its most prominent employees, and the dissolution of the "Super Alignment" team have once again put OpenAI's security issues in the spotlight. Fortune magazine reported that OpenA

Open-Sora has been quietly updated in the open source community. It now supports video generation up to 16 seconds, with resolutions up to 720p, and can handle text-to-image, text-to-video, image-to-video, and video-to-video of any aspect ratio. and the generation needs of infinitely long videos. Let's try it out. Generate a horizontal screen Christmas snow scene, post to B site and then generate a vertical screen, and use Douyin to generate a 16-second long video. Now everyone can have a screenwriting addiction. How to play? Guidance GitHub: https://github.com/hpcaitech/Open-Sora What’s even cooler is that Open-Sora is still all open source, including the latest model architecture, the latest model weights, multi-time/resolution/long-term

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps
