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

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.

identification. The header of each large data block must have SI. In this way, when they reach the target end, it can be correctly put into its stream, where SI is a 16-digit number starting from 0. 2.3 stream serial number when a large data block reaches the target SCTP, it is passed to the appropriate stream and arranged according to the original sequence. In addition to SI, SCTP also uses stream sequence number (SSN) to define each data block in e

attributes in public, feather-level, and shared accessories. This type of configuration allows customers to use properties without referencing unwanted accessories. Which accessories will recognize attributes? If there is no module read attribute, it will be worthless. You may put the class that reads the attribute in the same assembly where the attribute resides. However, as mentioned above, you want to put the methods and attributes for reading attributes in different accessories. Public stri

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

DataTable's Sort property to sort the results by the specified column. if you want to stay away from DataTables and use just the more efficient DataReaders, you might pine for some means to pass in the column to sort by into the stored procedure. unfortunately, the following stored procedure is not valid.
