Currently, there is a limitation that a table can only be joined once. I wanted to join the same table multiple times - however, only the first join worked. All the other joined fields appear empty.
My use case:
table traffic_sign_posts (can have up to 4 different traffic signs) - has, amongst others, the following integer columns:
table traffic_signs - has the following columns:
- code (link to sign1 to sign4)
Now I wanted to join table "traffic_signs" 4 times to the table "traffic_sign_posts", joined with columns "sign1" to "sign4".
