SQL ServerExtended Event (Extended Events)--ArchitectureMsdn:http://msdn.microsoft.com/zh-cn/library/bb630282%28v=sql.110%29.aspxblog:http://blogs.msdn.com/b/extended_events/SQL Server Extended events have a highly scalable and highly configurable architecture that enables users to gather the information they need to address performance issues or identify performance issues on demand.

C disk is the system disk, not enough space will make the computer slow, affecting the operation of the program or game. When you buy a computer, C disk may have enough free space, but with the use of computers, application installation more and more, although many programs are installed to D disk, but individual programs will still occupy part of the C disk space, over time, the system partition C disk free space will be less and fewer, Eventually had to divide some space from the other disk to

The euclidean algorithm, also known as the moving phase division, is used to calculate the maximum approximate number of two integers A and B. The computation principle depends on the following theorem: The GCD function is used to calculate the maximum approximate number of (a, B. Basic properties of the gcd function: gcd (a, B) = gcd (B, A) = gcd (-a, B) = gcd (| A |, | B |) the formula expression gcd (a, B) = gcd (B, A mod B) proves that a can be ex

Oracle online extended partitions and oracle online extended partitions In the Partition Table operation, when a partition already has the largest partition, how can we expand the partition again? The simple method is to delete the maximum partition first, then add the required partition, and create the maximum partition again. If the system is 7*24 hours old, it may not work. How can this problem be solved

EntityFramework. Extended is an extension method based on the EntityFramework IQueryable type, including Update and Delete. Its advantage is that the modification and deletion operation not only has an Id condition, but also has a condition; During modification, you can not only pass in the entire object type, but also pass in the content of the local field to be changed according to the condition. 1.

I always thought that the wss3.0 (MOSS) Folder does not support extended fields. All Folders only have a single "name" field, and I have to add a comment or something. In fact, WSS supports folder extension fields! There is no essential difference between a folder and a common listitem, except that a folder is a special contenttype. You can see this in the "website content type library" management interface of the site: With this in mind, we can

C ++ Study Notes 1 (extended: Format control in C ++), extended learning notes In the previous chapter, we learned about the standard input and output problems in C ++, so some people may ask questions. In the C language, we can flexibly control the output and display, can I implement it in C ++? My answer is certainly yes, but the control in C ++ may be a little more complicated than that in C ++, then let
