in your where clause what does 1 = 1 mean

[@coupleracademy]

1=1 is used to save the query structure. For example, you first want to use SELECT... FROM...WHERE country="Poland". Then you've decided to remove the criterion. If you leave it SELECT...FROM...WHERE - it won't work. If you remove WHERE and decide to add it again later you will have to remember where to put it not to break the query. In case of WHERE 1=1 you don't have to edit the query structure every time and it doesn't influence the output.
