The CreateClass method creates a new data class with a given set of public properties and returns the System.Type object for the newly created class. If a data class with an identical sequence of properties has already been created, the System.Type object for this class is returned. ...
When creating a natively compiled stored procedure, rather than using a cursor, use set-based logic or a WHILE loop. Feature Non-constant parameter defaults When using default values with parameters on natively compiled stored procedures, the values must be constants. Remove any wildcards from the...
Transact-SQL, known as T-SQL for short, is a set of programming extensions that enhances the capabilities of Structured Query Language (SQL). With Transact-SQL, developers gain access to additional features, such as row processing, transaction control, declared variables, and robust exception and...
