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

the user-defined data type. System_data_type are system-supplied data types, 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 '.Example:Use CustExec sp_addtype ssn, ' Varchar (one) ', ' not Null 'Creates a user-defined data type SSN, which is based on a system data type that is

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. System stored procedures sp_addtype can be used to create user-defined data types. The syntax is as follows: sp_addtype {type},[,system_data_bype][, ' null_typ

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
