Question

此代码不会更改fullname表中person列中的数据，也不会产生任何错误。我使用变量$editKey来获取要编辑的记录，因此它按计划运行：

def upDateRecord
  getInputs
  puts $editKey
  puts $fullname

  db = SQLite3::Database.open "ruby-test-02.db"
  db.execute "UPDATE person SET fullname = $fullname WHERE ID = $editKey"
rescue SQLite3::Exception => e 
  puts "Exception occured"
  puts e
ensure
  db.close

  puts $editKey
  puts $fullname      
end

Sloved ..

def upDateRecord 把“放在upDateRecord” getInputs

  db = SQLite3::Database.new "ruby-test-02.db"
  stm = db.prepare "UPDATE person Set fullname=? WHERE ID=?"; stm.bind_param 1, $fullname; stm.bind_param 2, $editKey;stm.execute;stm.close
  stm = db.prepare "UPDATE person Set sex=? WHERE ID=?"; stm.bind_param 1, $sex; stm.bind_param 2, $editKey;stm.execute;stm.close
  stm = db.prepare "UPDATE person Set birth=? WHERE ID=?"; stm.bind_param 1, $birth; stm.bind_param 2, $editKey;stm.execute;stm.close
  stm = db.prepare "UPDATE person Set death=? WHERE ID=?"; stm.bind_param 1, $death; stm.bind_param 2, $editKey;stm.execute;stm.close

救援SQLite3 :: Exception =＆gt; Ë 把“例外发生” 把e 确保 db.close 端

在SQLite中更新记录？
