Declare @strInput as varchar(20)
declare @intLocal as int
declare @chrLocal as char
DECLARE @strLocal varchar(10)
DECLARE @strFinal varchar(100)
Set @intLocal=1
Set @chrLocal=1
Set @strInput='bhaskar'
If exists (Select 1 from sys.tables where name ='temp')
DROP TABLE temp
Create table temp(chrValue Char(1), Cnt Int)
while (@intLocal < len(@strInput) )
begin
set @chrLocal = Substring(@strInput,@intLocal,1)
IF (Select Count(1) from temp Where chrvalue=@chrLocal)> 0
UPDATE TEMP
Set Cnt=Cnt+1
Where chrValue=@chrLocal
else
Insert Into temp (chrValue, Cnt ) values ( @chrLocal,1)
set @intLocal = @intLocal+1
end
Set @strFinal=''
DECLARE @curLocal CURSOR
SET @curLocal = CURSOR FOR
Select ChrValue + ': '+ Cast(cnt as varchar(2)) from temp
OPEN @curLocal
FETCH NEXT
FROM @curLocal INTO @strLocal
WHILE @@FETCH_STATUS = 0
BEGIN
----PRINT @strLocal
Set @strFinal =@strFinal + ' ' + @strLocal
FETCH NEXT
FROM @curLocal INTO @strLocal
END
CLOSE @curLocal
DEALLOCATE @curLocal
PRINT @strFinal
Output :
(1 row(s) affected)
(1 row(s) affected)
(1 row(s) affected)
(1 row(s) affected)
(1 row(s) affected)
(1 row(s) affected)
b: 1 h: 1 a: 2 s: 1 k: 1
