                             SQL Query to write A to Z 

                     Without Knowing the ASCII value of any Character



 declare @start int,@stop int     --We declare start and stop variable to hold from and to value
set @start= ASCII('a')              --We get ASCII value of 'a' in start variable
set @stop= ASCII('z')              --We get ASCII value of 'a' in start variable
while(@stop>=@start)             --We start loop. Loop terminate if start value is greater than stop value
begin
print CHAR(@start)
set @start=@start + 1
end





Now If you want to print A to Z means in Capital then we should set 

set @start= ASCII('A') 
set @stop= ASCII('z')  

And rest code will be the same.

Also we can use This code to print all numbers between two numbers.

Ado.Net is not a different technology. It is part of Asp.Net. It basically helps us to provide communication with back end data using front end controls.
Front end technology like C# and Back end technology like Sql server.We can use Ado.Net for fetching data from data services based on disconnected DataSets and XML.
ADO.NET is an object-oriented set of libraries that allows you to interact with data sources. Commonly, the data source is a database, but it could also be a text file, an Excel spreadsheet, or an XML file.
