我想授予Firebird中特定用户一些特权，就像我们可以在MySql中那样，如下所示。
CREATE USER 'user123'@'localhost' IDENTIFIED BY 'user123pass';
GRANT CREATE, SELECT, INSERT, DELETE, DROP, UPDATE ON MyTestDb.* TO 'user123'@'localhost';
在Firebird中可以吗？
答案 0 :(得分：0)
不幸的是，这是不可能的。您将需要为每个表或视图分别显式地授予特权。
另请参阅Firebird 2.5 Language Reference和Firebird 3 release notes中的class MyFragment : androidx.fragment.app.Fragment() {
private lateinit var mRecyclerView: RecyclerView
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
return inflater.inflate(R.layout.fragment_rv, container, false)
}
override fun onActivityCreated(savedInstanceState: Bundle?) {
val v = view
mRecyclerView = v!!.findViewById<RecyclerView>(R.id.my_recyclerview)
mRecyclerView.layoutManager = LinearLayoutManager(activity)
val myList = ArrayList<Item>()
val myListTitles = ArrayList<String>()
myListTitles.add("Tab A")
myListTitles.add("Tab B")
myListTitles.add("Tab C")
val myListDescriptions = ArrayList<String>()
myListDescriptions.add("Description A")
myListDescriptions.add("Description B")
myListDescriptions.add("Description C")
val mAdapter = MyAdapter(myList, childFragmentManager)
mRecyclerView.adapter = mAdapter
super.onActivityCreated(savedInstanceState)
}
}
