<p>Returns the string that results from concatenating the arguments
using a separator. The separator is added between the strings to be
concatenated. Returns NULL If the separator is NULL. concat_ws() does not skip
empty strings. However, it does skip any NULL argument. E.g.

<code>AA~BB~~CC</code></p>
