To write time in standard format to log files. To convert time (now () to character format "YYYY-MM-DD hh: mm: SS Zzz" Write this function, Delphi system itself also with the Conversion Function formatdatetime ('yyyy-MM-DD hh: mm: SS zzz', now ()) You can also implement this function. Considering that this is a fixed-format conversion function for further optimization. // Actual test results Run 1,000,000 f

Label:The SQL Server 2005 version starts with support for window functions (windowing function) and over words. The SQL Server 2012 version begins to support the sequential/cumulative aggregation of window functions by the ORDER BY clause. However, there is a feature to the SQL Server 2014 version (from the current SQL Server CTP3, or not supported), that is, count (DISTINCT XXX) over (PARTITION by YYY ORDER by ZZZ).

only be used within a function are called "local variables".Note: The var keyword is omitted anywhere, and the variables defined are "global variables" (which can be used outside of the function) so, in general, do not omit the var keyword.Assignment Value and assignment address:Assignment value: Used to assign a basic data type (only one value) to a variable.Reference address: Used to assign a composite data type (possibly with multiple values) to a variable. All two variables change at the sa

OC-class definition and oc-DefinitionWe have already introduced a program HelloWorld: Keep in OC. The biggest difference between OC and C is that it has the Object-Oriented function. When it comes to object-oriented, we have to talk about the class concept. If we have learned Java, so there is no stranger to the concepts of classes and objects, Because Java is a very pure object-oriented design language. I will not elaborate on the concepts of classe

　　They have a common advantage is "change the whole, to avoid the input error" What are the two different? Some.The main difference is that the macro definition is done prior to compilation, and the const is processed during the compilation phaseMacros define constants that do not occupy memory cells and are defined by const occupy memory unitsA macro definition has the same effect as a const constant-----t

C ++ macro definition commands and macro definition commandsCommands starting with # In a program are pre-compiled commands. There are three types of pre-compiled commands: macro definition commands, file inclusion commands, and Conditional compilation commands. Today we will talk about macro definition: macro

Recently, when I was working on the preliminary code architecture of the cloud platform, I encountered a constant definition speed comparison problem, so I would like to make a comparison.The APC extension of PHP is described in the following section in the PHP manual:Http://cn.php.net/manual/zh/function.apc-define-constants.phpDefine () is notoriously slow. Since the main benefit of APC is to increase the performance of scripts/applications, this mec

To write a good C language, a beautiful macro definition is very important. Macro definitions can help us prevent errors, improve code portability and readability, and more.In the software development process, there are often common or common functions or code snippets that can be written as functions or encapsulated as macro definitions. So is the function good or the macro definition good? This requires u
