NET, won't permit name collisions, but adding a namespace to the using list makes coding easier by providing "shorthand" syntax for commonly used objects. Although not required for ADO. NET, the using directive signals the compiler to 18. NET and (very) loosely similar to the inclusion of header files in C and C++. NET search the specified namespace referenced in your code to resolve any ambiguous object names. Basically, using helps the compiler resolve namespace references more easily. The using statement should be positioned first in your code-above all other declarations.
This low-level data stream permits data providers to return resultsets to the client as quickly as the LAN can carry them. While fast, the default firehose ADOc Recordset does not support record count, cursors, scrolling, updatability, caching, filters, sorting, or any costly overhead mechanism that could slow down the process of getting data back to the client.
