Joining strings is very easy in SQL - you can just use a + sign.
However, there are advantages to using CONCAT, if you are joining a string to a NULL.
Need a separator between string items? Then is when you can use CONCAT_WS.
However, what if you want to join together strings in multiple rows into one big string? You can use STRING_AGG to do this, and include a separator as well if you wish.
