在做向Access数据表增加数据时,如何让数据库自增主键?
我的sql语句是string sqlstr = "insert into PutOption values(@id,@productCode,@productType,@contractMonth,@strikePrice,@reserve,@issueCode,@closingPrice," 我想要的是把@id这个值去掉,让它像在sqlserver里面一样随着 数据 增加 而增长,不用再sql语
我的sql语句是string sqlstr = "insert into PutOption values(@id,@productCode,@productType,@contractMonth,@strikePrice,@reserve,@issueCode,@closingPrice,"
我想要的是把@id这个值去掉,让它像在sqlserver里面一样随着数据增加而增长,不用再sql语句给他指定值
还有疑问就是access中主键也必须给它指定一个值添加到数据库吗,没有id值一直报“字段数不匹配查询的输出”的错误

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,

70B model, 1000 tokens can be generated in seconds, which translates into nearly 4000 characters! The researchers fine-tuned Llama3 and introduced an acceleration algorithm. Compared with the native version, the speed is 13 times faster! Not only is it fast, its performance on code rewriting tasks even surpasses GPT-4o. This achievement comes from anysphere, the team behind the popular AI programming artifact Cursor, and OpenAI also participated in the investment. You must know that on Groq, a well-known fast inference acceleration framework, the inference speed of 70BLlama3 is only more than 300 tokens per second. With the speed of Cursor, it can be said that it achieves near-instant complete code file editing. Some people call it a good guy, if you put Curs

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
