Seungun Choe commented on TAJO-378:
-----------------------------------
This function's definition is, concat_ws(sep text, str "any" [, str "any" [,
...] ]).
For example, concat_ws(',', 'abcde', 2, NULL, 22)'s result is abcde,2,22.
Detailed description is "Concatenate all but first arguments with separators.
The first parameter is used as a separator. NULL arguments are ignored.". :)
> Implement concat_ws function.
