Group function not working on SQL server -


i use below query, shows repeated items. use group function, not work.

select p.productid, p.productname, p.catid, p.subcatid, p.producttype,        p.modelno, p.picurl, p.color, p.theme, p.productprice, p.discountedprice,        p.quantity, p.details, p.mainpagedisplay, p.productpagedisplay,        s.subcatid expr1,        s.subcatname, s.catid expr2,        s.rank, s.subcatname expr3 (products p inner join       subcategories s on p.catid = s.catid) (p.color = 'red') group p.productname

this query working fine, when add group by it's not working.

you don't need group by selecting distinct rows, need distinct:

select distinct p.productid, p.productname, p.catid, p.subcatid, p.producttype,        p.modelno, p.picurl, p.color, p.theme, p.productprice, p.discountedprice,        p.quantity, p.details, p.mainpagedisplay, p.productpagedisplay,        s.subcatid expr1,        s.subcatname, s.catid expr2,        s.rank, s.subcatname expr3 (products p inner join       subcategories s on p.catid = s.catid) (p.color = 'red')

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
