I have written query to do this using Charindex it is finding only one how to go for 2nd one I am only finding the 2nd word through index how to find other words also 

select UPPER(LEFT(SUBSTRING('AHRQ utilization flag',CHARINDEX(' ','AHRQ utilization flag',0)+1,
len('AHRQ utilization flag')),1))

For example, Sample input:

create function f_CamelCase
(
  @txt nvarchar(max)
) returns nvarchar(max)
as 
begin 
set @txt = stuff(lower(@txt), 1,1,upper(left(@txt, 1)))

declare @index int = 1
while @index > 0
begin

  set @index = patindex('%[ ][abcdefghijklmnopqrstuvxyz]%', @txt  
            COLLATE SQL_Latin1_General_CP1_CS_AS)

  select @txt = stuff(@txt, @index+ 1, 1, upper(substring(@txt, @index + 1, 1)))
  where @index > 0

end

return @txt
end

Test:

select dbo.f_CamelCase('aa b A b c')

Result:

Aa B A B C

You can write a function to convert desired string in camel case as below:

CREATE FUNCTION [dbo].[fn_CamelCase]
(@Str varchar(8000))
RETURNS varchar(8000) AS
BEGIN
  DECLARE @Result varchar(8000)
  SET @Str = LOWER(@Str) + ' '
  SET @Result = ''
  WHILE 1=1
  BEGIN
    IF PATINDEX('% %',@Str) = 0 BREAK
    SET @Result = @Result + UPPER(Left(@Str,1))+
    SubString  (@Str,2,CharIndex(' ',@Str)-1)
    SET @Str = SubString(@Str,
      CharIndex(' ',@Str)+1,Len(@Str))
  END
  SET @Result = Left(@Result,Len(@Result))
  RETURN @Result
END  
Go

and then call the same as:

select 'AHRQ ' + dbo.fn_CamelCase ('utilization flag')

One method could be:

Split the string into the first char UPPER and the rest like so:

UPPER(LEFT(string)) + RIGHT(string, LEN(string) - 1)

Then replace any space followed by a letter with the upper case of it such as:

REPLACE(string, ' a', ' A')

Combining the above, you can do this:

SELECT 
    UPPER(LEFT('have a great day')) + 
    REPLACE((((((((((((((((((((((((((
        RIGHT('have a great day', LEN('have a great day') - 1)
    , ' a', ' A'), ' b', ' B'), ' c', ' C')
    , ' d', ' D'), ' e', ' E'), ' f', ' F')
    , ' g', ' G'), ' h', ' H'), ' i', ' I')
    , ' j', ' J'), ' k', ' K'), ' l', ' L')
    , ' m', ' M'), ' n', ' N'), ' o', ' O')
    , ' p', ' P'), ' q', ' Q'), ' r', ' R')
    , ' s', ' S'), ' t', ' T'), ' u', ' U')
    , ' v', ' V'), ' w', ' W'), ' x', ' X')
    , ' y', ' Y'), ' z', ' Z')

Might need some tweaking since I haven't actually tested it
