I'm sure there is an answer present for this question but bear with me as I'm new to SQL and am not sure how to ask the question.

I have data like this (this is shorthand purely for example). This is in a postgres db.

table1
id    value
1     111
1     112
1     113
2     111
2     112
2     116
3     111
3     122
3     123
4     126
5     123
5     125
6     111
6     112
6     116

table2
value
111
112
116

I need return the id of table1 where all values in table2 exist in the values of table1. So for this example, my query would return 2 and 6.

Is there any way to do this in SQL? Or could you possibly guide me to a data structure that would allow for me to get this result? I am able to change up the structure of either table to accommodate the ultimate need of getting this result

Thank you so much. An answer to this would be a life saver.
