Preface: Last time I wrote an article about indexes, several insite emails from yuanyou asked me how to store indexes and tables on different hard disks. I think it should be easier to write an article to describe files and file groups. Introduction In SQL Server, the storage method of the database on the hard disk is no different from that of the common files in windows, just a few

1. OBJ fileProgrammers write programs by writing a binary file. If we declare a variable char C, that is, the Declaration requires an 8-bit space, then we need to declare to the system that the 8-bit space is reserved. How can we do this? It is to compile a special binary file-OBJ file. The execution file obtained by using the C language compiled by GCC contains not only CPU commands, but also a lot of other information, it has many coff, elf ...... In the last compilation process, the linker LD

Introduce as few header files as possible in Class header files Like C and C ++, Objective-C uses header files and implementation files to separate code. The standard method for compiling "class" in Objective-C language is to create two files by using the class name as the

In some cases, you need to relocate multiple Oracle data files and log files or migrate them to new partitions or locations, such as insufficient disk space or special requirements. In this case, you can migrate multiple data files or log files in batches. Of course, Backup recovery is also one of the methods. This doc

The next is the batch of the backup, added to the scheduled task, set the time to run automatically Copy Code code as follows: @echo off REM Format Date REM date is "2006-02-22 Wednesday" and cannot be used directly, so you should format it first. REM becomes what we want. date:~0,4 means to intercept 4 characters starting from 0. Set d=%date:~0,4%%date:~5,2%%date:~8,2% REM Sets the compression program path, which is packaged with WinRAR Rar.exe. Set Path=c:\program

The CHM is a shorthand for English "Compiled help Manual", which is "compiled helper Files". CHM is a new generation of Microsoft's Help file format, using HTML as the source text, the Help content in a similar database compiled storage.The advantages of CHM files are lightweight, convenient, read-only, etc., through the directory, can be conveniently located in the file location, but it also has a big flaw
