Joining dictionaries to make a table

  • A+
Category:Languages

I get a table when I join the dictionaries with same keys :

q)((`s`p!`s1`p1);(`s`p!`s2`p2))  s  p  ----- s1 p1 s2 p2 

But if keys are different it just returns the list, is there a way to generate a proper table?

q)((`s`p!`s1`p1);(`s`p`m!`s2`p2`m2))  `s`p!`s1`p1 `s`p`m!`s2`p2`m2 


You can use uj along with adverb over to get the table:

q)(uj)over enlist each ((`s`p!`s1`p1);(`s`p`m!`s2`p2`m2))  s  p  m  -------- s1 p1    s2 p2 m2 

Please note that we first made the individual dictionary to table before joining.

The over is particularly useful when there are more than 2 dictionaries. Otherwise using uj alone can do the trick.

q)(enlist `s`p!`s1`p1) uj (enlist `s`p`m!`s2`p2`m2)  s  p  m  -------- s1 p1    s2 p2 m2
