sql server - Convert columns to rows by ID -

-

looking way convert columns rows in sql server.

i have table columns below:

[id] [action] [note] [resolution]

here want result columns: [id] [notes] , result values be:

'1' 'action1' '1' 'note1' '1' 'resolution1' '2' 'action2' '2' 'note2' '2' 'note2.1' '2' 'resolution2' etc

any ideas how in t-sql? note field there multiple entries. thanks!

assuming source table , data looks this:

-- select * t: id  action  note    resolution --- ------- ------- ----------- 1   action1 note1   resolution1 2   action2 note2   resolution2 2   action2 note2.1 resolution2

this query:

select distinct id, notes (select * t) source unpivot (notes ids in ([action], [note], [resolution]) ) unpivotted_table

will produce result:

id  notes --- ------ 1   action1 1   note1 1   resolution1 2   action2 2   note2 2   note2.1 2   resolution2

which looks lot asking for.

you can find more information on how unpivot operator works here.

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
