rn 3500

This article mainly consists of two aspects, how to integrate the RN (React-native) project into the existing Android project starting from 0, as well as some pits we have encountered in the first RN's on-line project.To do the RN project for the first time, we chose to do a logical and relatively simple internal help center project for the transfer app. The entire project has 4 pages with the

information from the Uikit. The output of this command is arranged in the order in which the function is implemented in Uikit, which is the function of the-s address.There's a lot of useful information here, but you can't read all the content. You need an efficient way to find the code that interests you in Uikit.The image Lookup command can perfectly filter out all the data. Enter the following command:(lldb) Image Lookup-n "-[uiviewcontroller viewdidload]"This extracts only the content relate

Difference: Listagg is a new function of 11.2, and the function can implement sorting within a group The--vmsys.vm_concat function is grouped by department as shown below, separated by commas in the same groupSELECT Deptno, Wmsys.wm_concat (ename) from EMP GROUP by Deptno; Listagg function: Sys_connect_by_path function: SELECT Sys_connect_by_path (ename, ', ')From (SELECT ename, Deptno, rownum RN from EMP)START with

of this principle, the so-called Tiger painting is not a dog-like. However, to solve the problem is always the first principle, here is a more representative of a SQL method. SELECT Country,max (substr (city,2)) City From (SELECT Country,sys_connect_by_path City, ', ') From (SELECT country,city,country| | RN rchild,country| | (rn-1) Rfather From (SELECT Test.country, Test.city,row_number () over (PARTITION

This article is written a long time ago, just turned over the hard drive, and now put it out. This is just a formal idea, temporarily no time to implement, I have simply verified the formal process, the temporary has not found a problem, but do not guarantee that the process is not a problem. If you find a problem, please correct me, thank you! In the field of vertical search, there is no standard for judging the result of ranking, so the role of supervisor is introduced, and the algorithm is d

Tags: Group by usage resolves the group by syntax to group the query results by each member of a given data column, resulting in a grouped summary table. The column name in the SELECT clause must be a grouping column or a column function. The column function returns a result for each group defined by the GROUP BY clause.

The previous four articles about how to use SQL to convert the result set may be a headache when the rows are converted into columns, but they can still be solved after finding a solution. One of them is, for the N rows in each group, assuming that the n rows must be in the same row in the result set together, we try to make a column of the N rows in each group (assuming RN) the values are the same, which can be implemented using the window function r

Listparts and vmsys. vm_concat: Convert rows into columns and separate them with commas. Difference: listparts is a new function added in 11.2, and this function can be used to sort in groups. -- The vmsys. vm_concat function is grouped by department as follows. The same group is separated by commas (,) in a row.Select deptno, wmsys. wm_concat (ename) from EMP group by deptno; Listparts function: Sys_connect_by_path function: Select sys_connect_by_path (ename ,',')From (select ename, deptno, ro

From: http://blog.csdn.net/seventh1984/archive/2009/02/26/3940168.aspx I personally think this function is actually very useful. sys_connect_by_path (field name, The Connection Symbol between two fields). Note that the Connection Symbol here should not be a comma. Oracle will report an error. If you must use it, replace can be used as follows: Replace (field name, original character ,',').Also, you must create a tree before using this function. Otherwise, it is useless.For example:Objective: To
