Question

我有一个由时间序列字段（集合）组成的表，我打算根据某些条件对时间序列进行分类。

表cses_test是

GEOC_LAT_   GEOC_LONG_  KP_          UT_    LABEL   EQ_NUM
<Collection>    <Collection>    <Collection>    <Collection>    -1  0
<Collection>    <Collection>    <Collection>    <Collection>    -1  0
<Collection>    <Collection>    <Collection>    <Collection>    -1  0

表eq_test是

TIME_                               LATITUDE          LONGITUDE      EQ_NUM
2019-04-25 02:27:59:000000  -57.930 -57.2700000 1
2018-08-03 00:21:31:956000  64.900  -139.0000000    2

某些条件是：

如果KP_> 3中有任何值，请更新表cses_test = 2的LABEL；

UPDATE cses_test
   SET LABEL =
           (SELECT (CASE
                        WHEN (  COUNT (
                                    CASE WHEN COLUMN_VALUE > 3 THEN 1 END)
                              / COUNT (*)) >
                             0
                        THEN
                            2 
                        ELSE
                            -1
                    END)
              FROM TABLE (KP_));

如果KP_中的任何值<= 3，并且GEOC_LAT_，GEOC_LONG_和UT_中的值的80％在表eq_test中的任何地震的影响范围内，则更新表cses_test = 1的LABEL表cses_test的表的EQ_NUM =表eq_test中的对应EQ_NUM;
如果KP_中的任何值<= 3，并且GEOC_LAT_，GEOC_LONG_和UT_中的值的80％不在表eq_test中任何地震的影响范围内，则更新表cses_test = 0的LABEL；

任何地震的影响范围是：震中10°以内，以及地震发生前2天（BETWEEN（EQ.TIME_-（24 * 20/24））和EQ.TIME_； BETWEEN EQ.LONGITUDE / EQ .LATITUDE-10和EQ.LONGITUDE / EQ.LATITUDE + 10）

我的预期结果是

GEOC_LAT_   GEOC_LONG_  KP_          UT_               LABEL     EQ_NUM
<Collection>    <Collection>    <Collection>    <Collection>            0       0
<Collection>    <Collection>    <Collection>    <Collection>    1       2
<Collection>    <Collection>    <Collection>    <Collection>    2       0

Answer 1

嗨，请尝试这段代码。 COMMIT不是故意添加的。您可以在确定此代码将完成此工作之后将其添加。不完美，但是...

This is the ChatsAdapter:
class ChatsAdapter (mContext: Context, mChatList: List<Chat>, imageUrl: String)
    : RecyclerView.Adapter<ChatsAdapter.ViewHolder>()

{
    private val mContext: Context
    private val mChatList: List<Chat>
    private val imageUrl: String
    var firebaseUser: FirebaseUser = FirebaseAuth.getInstance().currentUser!!

    init {
        this.mChatList = mChatList
        this.mContext = mContext
        this.imageUrl = imageUrl
    }

    inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView)
    {
        var profile_image: CircleImageView? = null
        var show_text_message: TextView? = null
        var left_image_view: ImageView? = null
        var text_seen: TextView? = null
        var right_image_view: ImageView? = null

        init {
            profile_image = itemView.findViewById(R.id.profile_image)
            show_text_message = itemView.findViewById(R.id.show_text_message)
            left_image_view = itemView.findViewById(R.id.left_image_view)
            text_seen = itemView.findViewById(R.id.text_seen)
            right_image_view = itemView.findViewById(R.id.right_image_view)
        }

    }

// Inside the ChatsAdapter there is a function that involves the seen tag:

override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        val chat: Chat = mChatList[position]
        if (position == mChatList.size-1)
        {
            if (chat.getIsseen()!!)
            {
                holder.text_seen!!.text = "Seen"
                if (chat.getMessage().equals("sent you an image.") && !chat.getUrl().equals(""))
                {
                    val lp: RelativeLayout.LayoutParams? = holder.text_seen!!.layoutParams as RelativeLayout.LayoutParams?
                    lp!!.setMargins(0, 245, 10, 0)
                    holder.text_seen!!.layoutParams = lp
                }
            }
            else
            {
                holder.text_seen!!.text = "Sent"
                if (chat.getMessage().equals("sent you an image.") && !chat.getUrl().equals(""))
                {
                    val lp: RelativeLayout.LayoutParams? = holder.text_seen!!.layoutParams as RelativeLayout.LayoutParams?
                    lp!!.setMargins(0, 245, 10, 0)
                    holder.text_seen!!.layoutParams = lp
                }
            }
        }
