How to search with filtered no one items in table database?

Hello!

I know all items in tables: age, Banks, Gender, Insurance Company.
How can get rate, if all fields match? How to filtered no one item in table.

Do a search for the data type “number” not the table name.

Pull back the rate and maybe add :unique on the end so you only get the unique set.

What you mean?

Maybe I asked incorrectly. I am make form, user inpute Bank, Gender, Insure Company and Birthday (i am calculate age user) and me need get Rate from database. Need find date from form in database, If all data match get rate in table.
