PL/SQL-related data dictionary and plsql-related dictionary Data Dictionary related to PL/SQLHttp://www.oracle.com/technetwork/issue-archive/2012/12-nov/o62plsql-1851968.html Sometimes, we encounter the following problems during PL/SQL development:1) What database objects does my program depend on?2) which package calls a subroutine or variable in another packag

Objective-c dictionary object, objective-c dictionary The NSDictionary in oc serves the same purpose as the dictionary class in java and provides a combination of "key-value" pairs. For example, a dictionary class is used to store the Student name and student ID. The number is a key (unique) and the name is a value. It

Redis data structure (2) dictionary, redis Data Structure dictionary The Redis dictionary is actually a Hash table. Its implementation is similar to the hashmap structure in JAVA. Key-Value pairs are stored in Key-Value mode, but there are some differences.The hashmap structure in java contains the hash table and implements rehash self-expansion;The redis

Common Methods for operating the dictionary type in python (recommended) and for operating the dictionary type in python The has_key () method can check whether the dictionary contains the specified key. If yes, True is returned. Otherwise, False is returned. Syntax format: dictionary_name.has_key(key) dict1 = {'01':'yangry','02':'weild','03':'hexh','04':'huangmg

1. Introduction 在InnoDB启动时，如果是新建数据库则需初始化库，需要创建字典管理的相关信息。函数innobase_start_or_create_for_mysql调用dict_create完成此功能。即创建数据字典，因为InnoDB系统表的个数结构固定，所以初始化库的时候只需要创建这几个表的B+树即可并将B+树的根页号存放到固定位置。对于B+树，只要找到根页面，就可以从根页面开始检索数据。相关系统表（即上一节讲到的4个系统表）在InnoDB内部，不会暴露给用户。 4个系统表通过固定的硬编码进行构建。具体原理流程如下。2. Data dictionary creation and loading principle flow3. Description1) The Innobase_start_or_create_for_mysql function calls the Dict_create () function to create and load the d

Ios learns 8_KVC and dictionary-to-model, ios8_kvc dictionary Model Key Value Coding is a standard component of cocoa. It allows us to access attributes by name (key). In some cases, the code is greatly simplified, which can be called the big trick of cocoa. Example:Advantages of using KVC - (id)tableView:(NSTableView *)tableviewobjectValueForTableColumn:(id)column row:(NSInteger)row { ChildObject *chil
