‘Teacher’ is a table in a database. Based on that information,
explain what the following query is searching for in the table:
Teacher.find(:all, :condition => { :grade => 9…12})
Teacher.find(:all, :condition => { :grade => 9…12})
This means getting all records from teacher table teachers where
column grade has value between 9 & 12.
select * from teachers where grade between 9 and 12

It would be a better practice to include all column names in the Select
instead of *
