accessors. It is incorrect to use the base keyword in a static method. Call the base class method:Public class Person{Protected string ssn = "444-55-6666 ";Protected string name = "John L. Malgraine "; Public virtual void GetInfo (){Console. WriteLine ("Name: {0}", name );Console. WriteLine ("SSN: {0}", ssn );}}Class Employee: Person{Public string id = "ABC567EF

BaseKeyword is used to access a member of the base class from a derived class: Call methods that have been overwritten by other methods on the base class. Specify the base class constructor to call when creating a derived class instance. Base Class access can only be performed in constructors, instance methods, or instance attribute accessors. Use from static methodsBaseKeyword is incorrect.Example In this example, the base classPersonAnd Derived classesEmployeeEach has a nameGetinfo. UseBas

Indexing is one of the most efficient ways to obtain data from a database. Index technology can be used to solve 95% of database performance problems. 1. Do not index frequently used small tables Do not set any keys for small data tables. Do not do this if they are often inserted or deleted. The index maintenance for these insert and delete operations may consume more time than the scan tablespace. 2. Do not select the social security number (SSN

/// As can be seen from the instance code, this keyword has three main functions: 1. Use this to eliminate ambiguity. This keyword provides access to the current class instance. 2. Use this to call the series constructor. This design mode is useful when the class defines multiple constructors.

type. System_data_type are data types provided by the system, such as Decimal, Int, Char, and so on. Null_type indicates how the data type handles null values and must be enclosed in single quotes, such as ' null ', ' NOT null ', or ' nonull '.

data type that you are basing on, and the nullability of the data type.(1) Create a user-defined data typeYou can use Transact-SQL statements to create user-defined data types. System stored procedures sp_addtype can be used to create user-defined data types. Its grammatical form is as follows:sp_addtype {type},[,system_data_bype][, ' null_type ')Where type is the name of the user-defined data type. System_data_type are system-supplied data types, such as Decimal, Int, Char, and so on. Null_typ

, and to ensure that the columns have the same data type, length, and nullability. For example, you can define a data type called Postal_Code, which is based on the Char data type.When you create a user-defined data type, you must provide three numbers: the name of the data type, the system data type that you are basing on, and the nullability of the data type.1) Create a user-defined data typeYou can use Transact-SQL statements to create user-defined data types.

1974, an archaeological team found a completely different sword in the crater. What surprised the experts was that the length of the sword exceeded 91 cm! It can be inferred that Qin Shihuang was wearing such a long sword. It is really not easy for an assassin to pull out a long sword that is nearly one meter long. Experts are confused: What is the purpose of the Qin Dynasty to lengthen the sword? In the 19th century, British ancient weapons scholar Richard Burton believes that in short weapons
