sql - How to make dynamic pivot for this table when I pass only one parameter @did int? -


i have 2 tables, @details , @contactdetails. in 2 tables, @details static table in contactid primary key, , foreign key @contactdetails

here tables data:

declare  @details table (contactid  int identity(1,1), value varchar(200))  insert @details     select  'phonenumber' union     select  'mobilenumber' union     select  'address1' union     select  'address2'  union     select  'employeename'  union     select  'employeeid'  declare  @contactdetails table (detailid int identity(1,1),                                  did int,                                 contactid int,                                  detailsvalue varchar(200)                                )  insert @contactdetails     select  1,5,'siva' union     select  1,6,'sia001' union     select  1,2,'9344139991' union     select  2,1,'245678' union     select  2,2,'1686597' union     select  2,5,'ganesh' union     select  1,3,'st-road'  select * @details

the output is:

contactid value ---------------------- 1         phonenumber 2         mobilenumber 3         address1 4         address2 5         employeename 6         employeeid   select * @contactdetails

the output second query is:

detailid did contactid detailsvalue ----------------------------------- 1        1   6         siva 2        1   5         sia001 3        1   2         9344139991 4        2   1         245678 5        2   2         1686597 6        2   5         ganesh 7        1   3         st-road

in @contactdetails column have value of did column used show 1 particular employee detail in stored procedure using

parameter @did int - tried query

declare @did int=1   select       (select value @details contactid=a.contactid)as contactid,      a.detailsvalue         @contactdetails             a.did=@did

which show result this

contactid   detailsvalue employeeid  siva employeename    sia001 mobilenumber    9344139991 address1    st-road

and trying output this

employeeid  employeename  mobilenumber   address1 sia001      siva          9344139991       st-road

can 1 plz me

the basic set if know value ahead of time be:

select * (   select c.did,     d.value,     c.detailsvalue   details d   inner join contactdetails c     on d.contactid = c.contactid ) src pivot (   max(detailsvalue)   value in (employeeid, employeename, address1,                 mobilenumber, phonenumber) ) piv;

see sql fiddle demo

the above gets of values if want implement dynamic sql filter result based on @did, use:

declare @cols nvarchar(max),     @query  nvarchar(max),     @did int  set @did = 1  select @cols = stuff((select ',' + quotename(d.value)                      details d                     inner join contactdetails c                       on d.contactid = c.contactid                     c.did = @did                     group d.value, c.detailid                     order c.detailid             xml path(''), type             ).value('.', 'nvarchar(max)')          ,1,1,'')  set @query = 'select ' + @cols + '                             (                 select                    d.value,                   c.detailsvalue                 details d                 inner join contactdetails c                   on d.contactid = c.contactid                 c.did = '+cast(@did varchar(10))+'             ) x             pivot              (                 max(detailsvalue)                 value in (' + @cols + ')             ) p '  execute(@query);

Why does Ruby on Rails generate add a blank line to the end of a file? -

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
