How to set a condition for occurrence when selecting data from the Sqlite3 database?

Question

SQLite

I have a Sqlite3 database. Is it possible to put a condition on the entry when receiving data from it. For example, there is such a phrase - " how are you, man ." And in the database = " how are you ". And you need to select this line.
SELECT * FROM table WHERE words = 'how are you, man' - this checks completely for comparison, but I need it for occurrence. How can you do that?
Oh, and also, is it possible to do the same on PostgreSQL?

Answer 1

... where words like 'как дела%'
