sql server - SQL selecting with multiple joins -


i have example of database 3 tables.

1 work: workid, stateid, createddate  2 work history table: workid, old_state, new_state, transitiondate  3 work state: stateid; statename

let's possible states 1 = ready, 2 = test , 3 = approved

i want make query print list works , of state changes. results should this:

id, createddate, currentstate, oldstate, newstate, transitiondate 1,  1-1-2016,    approved,     ready,    test,     1-1-2016 1,  1-1-2016,    approved,     test,     approved, 2-1-2016 2,  1-5-2016,    test,         ready,    test,     1-5-2016 3,  1-10-2016,   approved,     ready,    test,     1-10-2016 3,  1-10-2016,   approved,     test,     approved, 1-15-2016  ...

i know how make inner join can name of current state of work state table, can't names of old , new state. sort of join commands should use?

please use below query - 

select t1.workid , t1.createddate , t3.statename currentstate , t4.statename oldstate , t5.statename  newstate, t2.transitiondate [work] t1 join [work history] t2 on t1.workid = t2.workid join [state] t3  on t3.stateid = t1.stateid join [state] t4  on t4.stateid = t2.old_state join [state] t5  on t5.stateid = t2.new_state

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
