In SQLServer, you can use extended stored procedures to implement remote database backup and recovery. For more information, see
SQL Server implements remote database backup and recovery through extended stored procedures. For more information, see
This article explains how to extend the stored procedure of SQL Server database through examples to achieve remote backup and recovery.

During this period, when purchasing storage and communicating with many storage vendors, we mentioned that it supports dynamic expansion of storage capacity. For example, if the original storage capacity is 5 TB, A lun will be allocated. Later, due to business needs, it will need to be extended to 1.
During this period, when purchasing storage and communicating with many storage vendors, we mentioned that it supports dynamic expansion of storage capac
On the extended Euclidean algorithm (Extended Euclidean algorithm), I was working on the classic topic of frog dating to get access to this algorithm. There is also an AC code and a solution to the problem.Content: Known A, B, solves a set of X, Y, and satisfies the Bézout equation: Ax+by =gcd (A, B)Extending Euclid's algorithm, like its name, is an extension of Euclid's algorithm. What is an extension? Fir
SQL Server's extended storage process is actually a common WindowsDLL, but some functions are implemented according to certain rules. Recently, when writing an extended storage process, I found that there are still some important points to note when writing this kind of dynamic library. Note that the DLL runs in the address space of SQLServer.

I have already mentioned in my previous blog that I have used the Chinese Remainder Theorem to find the same equations. This time I have gained some benefits, so I will discuss it in detail.
Before talking about the Chinese residue theorem, let's talk about Euclidean Algorithm and Extended Euclidean Algorithm:
First, the Euclidean algorithm calculates the maximum common divisor of two numbers using recursion. The basis is the theor
$ _ SESSION [expanded] [$ _ GET [expand] true; what do you mean
This is a strange way.
Reply to discussion (solution)
$ _ GET ['expand'] is used to obtain the parameter value passed in get mode.$ _ SESSION ['extended'] [] is a two-dimensional array. For example, the value of $ _ GET ['expand'] is abc.So$ _ SESSION ['extended'] [$ _ GET ['expand'] = true;Equal$ _ SESSION ['
Regular Expressions include basic regular expressions and extended regular expressions.
In general, grep uses a basic regular expression. To use an extended regular expression, you can use the-E Option, equivalent to egrep.
Other grep options:
-A n: displays the N rows after the matching row (after ).
-B N: displays n rows (Before) before the matching row ).
-C n: N rows before and after the display. (Conte

How to Set up the extended display in win10. how to set up the extended display for software development usually requires switching between multiple software, which is sometimes inconvenient. Then, you need to put another software on another monitor to facilitate development. In the Win10 system, how do I set up an

permissions for the folder are 777-022 equals 755, and the Rwxr-xr-x permissions are obtained after conversion.You can view or modify the values of the default permissions by using the Umask commandUse the umask command directly when viewing, but note that Umask returns a four-bit number where the first bit represents extended permissions. The latter three bits are normal permissions.Use the Umask value when modifying, for example to change the umask

Regular expressions are divided into basic regular expressions and extended regular expressions.Typically, grep uses a basic regular expression, and if you want to use an extended regular expression, you can use the-e option, which is equivalent to EgrepSome other options for grep:-A N: Displays the n rows after the matching line, (after).-B N: Displays the n rows preceding the matching line, (before).-C N:
Unpublished extended stored procedure injection in SQL ServerMany may not understand that SQL Server contains several extended stored procedures that can access the system registry. But in fact, these extended stored procedures are not made public. They are available from SQL Server 7.0 and are still retained in SQL Server 2000. They may be deleted in the future.
At the beginning of the system design, you may need to reserve an extended interface for the system so that you can add functions to the system after or after system development. blogengine. the extension mechanism in the. NET system is actually the application of events.
Nature of the extension mechanism:
