N_Sri, what is the goal?

If you just want a distinct listing of States, then you can do this w/o an aggregate function.

SELECT [State]
FROM Authors
GROUP BY [State]

If you are wanting something else, please clarify my initial question.

No . Goal is to see like all the  records   of particular state ..   and for all states .. like this..

State 1
    Author_ID , Author_FirstName,Author_LastName, State
State 2
    Author_ID , Author_FirstName,Author_LastName, State

State 3
    Author_ID , Author_FirstName,Author_LastName, State

What is wrong with viewing it like this:
SELECT [State], Author_ID , Author_FirstName, Author_LastName
FROM Authors
ORDER BY [State]

Open in new window


If you are outputting this to an application, what I would do is use the above query ordering by [State] and then in the loop to display authors I would have a variable that holds the state value of last iteration. If the current state equals the last state, I just show the new author. If state is different, I show the new state then new author. With the rows in order by state, I now a chance in state means a change in groupings.

I am not showing in any application, I am querying database.

Just want to get data as

State  California
     Author_ID , Author_FirstName,Author_LastName     record 1
     Author_ID , Author_FirstName,Author_LastName       record 2
     Author_ID , Author_FirstName,Author_LastName     record 3
State  ABC
 
   Author_ID , Author_FirstName,Author_LastName     record 1
   Author_ID , Author_FirstName,Author_LastName       record 2
   
State SomeState
 
   Author_ID , Author_FirstName,Author_LastName     record 1
   Author_ID , Author_FirstName,Author_LastName       record 2

Want to group  all records of particular state into one set...

Okay, if you are querying the database, again I will ask what is wrong with the order by. Given this is not a client app, but actual result set from SQL, you should expect this to be tabular and not in a tree.

If you really want to look at it this way, you could use XML:
SELECT [State] AS Name
     , (SELECT Author_ID, Author_FirstName, Author_LastName
	    FROM Authors a2
		WHERE a2.[State] = a1.[State]
		FOR XML PATH('Author'), TYPE, ROOT('Authors'))
FROM Authors a1
GROUP BY [State]
FOR XML PATH('State'), TYPE, ROOT('States')
;

Open in new window


Click on the result and you will get an XML display like:
<States>
  <State>
    <Name>ABC</Name>
    <Authors>
      <Author>
        <Author_ID>25</Author_ID>
        <Author_FirstName>Joe</Author_FirstName>
        <Author_LastName>Smith</Author_LastName>
      </Author>
      <Author>
        <Author_ID>125</Author_ID>
        <Author_FirstName>Joe</Author_FirstName>
        <Author_LastName>Myer</Author_LastName>
      </Author>
      <Author>
        <Author_ID>250</Author_ID>
        <Author_FirstName>Quincy</Author_FirstName>
        <Author_LastName>Tuplets</Author_LastName>
      </Author>
    </Authors>
  </State>
  <State>
    <Name>California</Name>
    <Authors>
      <Author>
        <Author_ID>1</Author_ID>
        <Author_FirstName>John</Author_FirstName>
        <Author_LastName>Smith</Author_LastName>
      </Author>
      <Author>
        <Author_ID>11</Author_ID>
        <Author_FirstName>John</Author_FirstName>
        <Author_LastName>Johnson</Author_LastName>
      </Author>
      <Author>
        <Author_ID>19</Author_ID>
        <Author_FirstName>Richard</Author_FirstName>
        <Author_LastName>Tracy</Author_LastName>
      </Author>
    </Authors>
  </State>
  <State>
    <Name>SomeState</Name>
    <Authors>
      <Author>
        <Author_ID>10</Author_ID>
        <Author_FirstName>Jerry</Author_FirstName>
        <Author_LastName>Smith</Author_LastName>
      </Author>
      <Author>
        <Author_ID>110</Author_ID>
        <Author_FirstName>Jerry</Author_FirstName>
        <Author_LastName>Riggs</Author_LastName>
      </Author>
      <Author>
        <Author_ID>140</Author_ID>
        <Author_FirstName>Charles</Author_FirstName>
        <Author_LastName>Smith</Author_LastName>
      </Author>
    </Authors>
  </State>
</States>

Open in new window


It serves purpose of viewing the data in a tree. If you just really want text.
SELECT CASE Author_ID WHEN 0 THEN [State] ELSE '' END AS [StateName]
     , Author_ID , Author_FirstName, Author_LastName
FROM (
SELECT [State], 0 AS Author_ID, '' AS Author_FirstName, '' AS Author_Lastname
FROM Authors a1
GROUP BY [State]
UNION ALL
SELECT [State], Author_ID , Author_FirstName, Author_LastName
FROM Authors
) t([State], Author_ID , Author_FirstName, Author_LastName)
ORDER BY [State], Author_ID

Open in new window


Then you can turn on Results to Text in SSMS:
StateName  Author_ID   Author_FirstName Author_LastName
---------- ----------- ---------------- ---------------
ABC        0                            
           25          Joe              Smith
           125         Joe              Myer
           250         Quincy           Tuplets
California 0                            
           1           John             Smith
           11          John             Johnson
           19          Richard          Tracy
SomeState  0                            
           10          Jerry            Smith
           110         Jerry            Riggs
           140         Charles          Smith
