GenerateCreationSQLOnView Method
В будущей версии Microsoft SQL Server эта возможность будет удалена. Избегайте использования этой возможности в новых разработках и запланируйте изменение существующих приложений, в которых она применяется.
The GenerateCreationSQLOnView method returns a string that contains a Transact-SQL command batch. This command batch can be used to create the Microsoft SQL Server index defined by the properties of the Index object used to create the index.

| SQL-DMO strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString. |
Замечания
The Index2 object exposes the GenerateSQLOnView and GenerateCreationSQLOnView methods. Both methods generate a command batch when creating an index. However, the Transact-SQL command batch returned by the GenerateCreationSQLOnView method prefixes an index creation statement with a statement that conditionally removes the index.
