First, class Cfilefindext function description
You often need to search for all files in the specified directory or to do the same. If the number of files, one by one for each file manual operation, very time-consuming. This article provides a C + + class that searches for or processes all files in a specified directory. The author implements a CFileFind extended class cfilefindext using a hierarchical traversal based non-recursive algorithm to reduc
, and if there is not enough log space, you can no longer modify the database (because you need to write to the log file). There are two ways to expand Database space: Add new files to the database, and enlarge the size of existing files in the database.① Adding a new file to the database?1234 ALTER Database nameADD [LOG] FILE????

Explanation of extended Chinese Remainder Theorem and explanation of Chinese TheoremPreface
Before reading this article, we recommend that you first learn the Chinese Remainder Theorem. In fact, it doesn't matter if you don't learn it. After all, there is no relationship between the two.Extended CRT
We know that the Chinese Remainder Theorem is used to solve the homogeneous equations.

In SQL server 2000, microsoft added extended attributes to help you define and operate user-defined attributes on multiple database objects. You can use these user-defined attributes to add metadata to your database. You can use system stored procedures

To manage these attributes. In addition, you can use system functions

, if integer B is satisfied with AB mod p = 1, B is the model p multiplication inverse element of.
Theorem: the necessary and sufficient condition for a multiplication inverse element with mod P is gcd (A, P) = 1.
Proof:First prove adequacyIf gcd (A, P) = 1, according to Euler's theoremObviously, a Phi (P)-1 mod p is the inverse element of the p multiplication mode of.Prove the necessityAssume that the multiplication inverse element of model a p is B.AB 1271 mod pThen AB = KP + 1, so 1 = AB-kPBe
Note:
Writing extended stored procedures is a bit the same as writing a common DLL, but note that your function interfaces should be compiled in C language.
