ruby sqlite error 'ensure in insert_row': undefined local variable or method 'stmt' -


i have following method in dbmgr ruby class, im using within loop insert data csv sqlite3 db:

  def insert_row(arow)     begin     @db = sqlite3::database.open("#{@dbn}")     rhash = arow.row_hash      stm = @db.prepare("insert programs (programname, episodename) values (? , ? )")         stm.bind_param(1, '#{rhash["program"]}' )         stm.bind_param(2, '#{rhash["episode name"]}' )         stmt.execute()         programid = @db.last_insert_row_id        rescue sqlite3::exception => e         puts "exception occured"         puts e.message         puts e.backtrace      ensure         stmt.close if stmt         @db.close if @db      end #db

when on console after 1st insertion following error:

  `ensure in insert_row': undefined local variable or method `stmt' #<dbmgr:0x007f9511050188> (nameerror)

initially did not use prepare , bind_params features of ruby sqlite. however, after characters " ' " in text inserting generated exceptions, read somewhere using bind_params clean input used bind_params. im getting error.

can please?

thanks

stm = @db.prepare("insert programs (programname, episodename) values (? , ? )")     stm.bind_param(1, '#{rhash["program"]}' )     stm.bind_param(2, '#{rhash["episode name"]}' )     stmt.execute() # <-- you're referring stmt instead of stm here     programid = @db.last_insert_row_id

you've used stm throughout statement, refer stmt.execute() , stmt.close
