Label:Row-to-column is a frequently encountered problem in SQL, and is divided into static and dynamic transformations, so-called static conversions are known or fixed in the number of rows converted; Dynamic conversions are not fixed for the number of rows converted. The method of conversion is generally implemented using case-when statements or pivot (MSSQL 2005 and later). Let's start with the static transformation: Prepare the test data and generate it directly using the following SQL statem

cryptography and cybersecurity, the Internet's status may not be so high today. Now the network is insecure, but when it comes to money-related problems, we need to ensure that there is enough security, if you feel that the network is not safe, will not be silly to enter their own Yinhangka information on the Web page.RSA algorithm, one of the most forked algorithms in the field of cryptography, is presented by the three founders of RSA, and lays the

only for the purpose of exchanging the full supply of money, the reserved currency can be exchanged for the sake of deleting the currency.Ore-Digging (mintable)--Almost the same as Bitcoin, you can use a work certificate (PoW) to dig a mine. Unlike bitcoin, money-mining does not ensure cybersecurity (the NXT did). Digging is the only way – to create a new currency unit and to increase the number of units available after the currency is issued.Not to

services provided by network access control, how to provide these services, and how to integrate these services into the network. The 2nd is to have a clear, enforceable security access policy. Network access control is not the creation of policies, but the implementation of policies. Without these two points, corporate cybersecurity will still be considered just the responsibility of the IT department (which is never a good thing). Is the connectio

decryption is as follows: Bob sends his public key to Alice. Alice encrypts her message with Bob's public key and sends it to Bob. Bob decrypts Alice's message with his private key. The above procedure can be shown in the following illustration, Alice uses Bob's public key for encryption, and Bob decrypts his private key.
