xml - SQL Server XQuery check data values before insert -


this on sql server 2012.

i have tsql create xquery statement shred , insert xml

the code looks this:

declare @xmlasxml xml set @xmlasxml = '       <data store="r262">         <s item1="10" item2="-1" />         <s item1="33.2" item2="55"  />       </data> '  insert tablex(oldprice, price)     select        c.value('@item1[1]','decimal(15,2)') oldprice,        c.value('@ut[1]','int') price           @xmlasxml.nodes('/data/s') t(c)

i want add data validation insert statement above (i don't want land data , have churn through again validate every data point)...

when data validation here's i'm saying:

  • if value item1 between 1 , 15 use insert otherwise insert null
  • if value item2 between -10 , 1000 use insert otherwise insert null.

i have see information on xquery think xquery has conditional logic can handle none of example have found align way i'm building , doing insert / select statement.

if there better way, i'm - long don't have shred data twice.

thanks in advance time! hope out there can me knock out! 

declare @xmlasxml xml     set @xmlasxml = '           <data store="r262">             <s item1="10" item2="-1" />             <s item1="33.2" item2="55"  />           </data>';  ;with tmp (     select c.value('@item1[1]','decimal(15,2)') oldprice,            c.value('@ut[1]','int') price       @xmlasxml.nodes('/data/s') t(c) )     insert tablex (oldprice, price)      select case when oldprice between 1 , 15 oldprice end,            case when price between -1 , 1000 price end       tmp;

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 ...
