executions (estimated executions and executions) 　　　　　　　　The operator estimates the number of executions and the actual number of executions. 6. Estimated operation cost (estimated operator overhead) The overhead of performing a specific operation. 7. Estimated subtree cost (estimated subtree size) It represents the cumulative total cost of the entire subtree until the current node. 8. Estimated number of rows (estimated rows) The number of rows that the operator expects to return. In some case

工欲善其事, its prerequisite.Before you formally implement all the cool features and UI, getting ready is the only way to improve the efficiency of your next development.So, this series, I am not in a variety of heap technology, more attention is "Bing" before the "grain line", some cumbersome, but when the whole context is clear, the follow-up work is only on the good Foundation and framework of unlimited expansion and optimization.Macro definition is an effective tool for improving efficiency in th

Original http://blog.csdn.net/ithzhang/article/details/8119286ThemeC + +C + + has been studying for years you know why when you define a class, the definition of the class is placed in the. h file, and the implementation of the class is placed in the CPP file. Why can they be linked together? You know what can be put in the. h file and what can't. What can be placed in the CPP file again. If you forget or do not understand, then read this article you will be very clear!! The difference betwee

First, discuss the difference between the declaration and the definition.The declaration is to introduce a name into the program. The definition provides a unique description of an entity in the program. declarations and definitions are sometimes present at the same time. such as int A; extern int b=1; The declaration is only declared if there is no initialization in extern. Other situations are both

complete definition of any type is incomplete, that an incomplete type can be used as a parameter and a return value for a function declaration, can be used as a pointer and reference to define the type, and can be used to declare it to be a static member of a type. However, the type member cannot be accessed through the type pointer and reference, and the type object cannot be defined (therefore, there is no type of nonstatic member of its own type, and its member functions can do anything wit

DDL (Data Definition definitions ages) and ddldefinition I haven't written any SQL statement for a long time. Let's review it. DDL defines different data segments, databases, tables, columns, indexes, and other database objects. Common DDL statements include create, drop, and alter. Logon data: mysql-uroot-p SQL commands generally end with a semicolon or \ g. Note that \ is not /. 1. Check the database show databases. Pay attention to the s following

Add module definitionCompleted the above articlesArticleAfter the introduction, we can add the module to dnn. Although this module cannot be run now, you can add it to view its effect while developing it. 1. log in as the host (host administrator), go to "host --> module definitions", and click "Add new module definition" to add a new module definition. 2. Enter the following module information and click "Update" to save the new module.Module name

Ios7: Random Talk#defineMacro definition#define宏定义在C系开发中可以说占有举足轻重的作用. The underlying framework does not have to say, in order to compile optimization and convenience, as well as cross-platform capabilities, macros are heavily used, it can be said that the bottom of development left define will be unable to move. When developing at a higher level, we put more emphasis on business logic and seem to have little use and reliance on macros. But the benefits of using macro
