depend on the recovery model of the database. Let's take a look at the examples below: --Paragraph restore: the database is corrupted in scope, and we have to restore the entire database across multiple data files and even across filegroups. -At this point, if the database is particularly large, the database recovery time will be very long. However, we can use the paragraph restore provided by SQL Server to recover the database gradually. --First back up the tail log: Backup log [Adventur

very good coordination to achieve some good application. For example, through the Regionprops function to determine the characteristics of each block (such as center, area, etc.) STATS = Regionprops (l,properties) measures a set of properties for each labeled RE Gion in the label Matrix L. 2, Regionprops: The purpose is get the properties of region, the function used to measure the properties of the image region. Syntax:

a syntax similar to the SET command, but includes an extra value: The extra value returned by the gets. Note the following interactions that use the CAS command: Set userId 0 0 5 55555 STORED gets userId 6 55555 END 6 33333 STORED As you can see, I call the gets command with an extra integer value 6来, and the operation runs in a very sequential order. Now let's take a look at the series of commands in Listing 7: Listing 7. CAS commands with older version indicators

DMP platform to analyze the user flexibly. And its definition of the Netizen entity also relies on the cookie, for example Baidu domain under the cookie Baiduid is Baidu uses the logo. The logo itself is an important part of each company's data and is therefore never exposed to third parties. In an important part of RTB-bidding, bid request typically contains a visitor ID provided by the AD Exchange platform, which can be interpreted as a cookie similar to UserID, but will never be ad The ID o

value we mentioned above. Then the CAS command is similar to the set command, but a parameter is added at the end, that is, the key version number. Only when the version number is consistent with the version number of the stored data, the update operation takes effect.
