Working with
concatto solve something yesterday i realized we also need the "with separator" version, as seen in MySQL, SQL Server, etc., so here it is.Concatenates together an abitrary number of strings, inserting a designated separator between each one. NULL strings are skipped in the output so you don't get pointlessly-duplicated separators.
Example:
CONCAT_WS(', ', 'apple', 'banana', NULL, 'date')will return'apple, banana, date'
