   Is it possible to replace this:

  DECLARE @sql varchar(255)

  DECLARE @tablename varchar(255)

  DECLARE @rcount int

  set @sql = 'Select COUNT(*) as COUNT into ##TEMPCOUNT from ' + @tablename

  EXECUTE sp_executesql @sql

  SELECT @rcount = [COUNT] FROM ##TEMPCOUNT

  with:

  set @sql = 'Select ' + @rcount + ' = COUNT(*) as COUNT from ' + @tablename

  EXECUTE sp_executesql @sql

  and eliminate the temporary table creation?

  Not possible. The variable @rcount is out of scope in Dynamic SQL.

  May be steev's answers in this helps

  Thanks a lot Govin.

   

  Steve's answer helped.

  This will do:

  set @sql = 'select @rcount = Count(*) from ' + @tablename

  exec sp_executesql @sql, N'@rcount int OUTPUT', @rcount OUTPUT
