How to arrange table data differently by using if, match, and index?

由 ℡╲_俬逩灬. 提交于 2020-01-06 21:05:48
问题 As shown in the attached image, I need to convert A2:D10 to the format of A12:E17. The 4 tables from F1 to AB12 are my experiments using if, match, and index. Same formula gets different results and it seems to be dependent on the row position of the tables. In My previous question, I was trying to pinpoint the problem to the if function. What am I doing wrong here? Thanks, Lu enter image description here 回答1: Again, as I said in your last question: The formula has not been array entered.

将查询的结果显示到一行记录中，以一个字符串数组的形式展示（ 看起来很方便 ） 查询所有电影的名字，并显示到一个数组中； MATCH (n:Movie) RETURN collect(n.title) 还可以和ORDER BY 一起使用，对数组内的结果排序后显示出来 MATCH (n:Movie) with n order by n.title desc RETURN collect(n.title) 来源： CSDN 作者： 陆家嘴的BA 链接： https://blog.csdn.net/fengjssy/article/details/103847287

How to test multiple variables against a value?

由 偶尔善良 提交于 2020-01-06 13:05:41
问题 I'm trying to make a function that will compare multiple variables to an integer and output a string of three letters. I was wondering if there was a way to translate this into Python. So say: x = 0 y = 1 z = 3 mylist = [] if x or y or z == 0 : mylist.append("c") if x or y or z == 1 : mylist.append("d") if x or y or z == 2 : mylist.append("e") if x or y or z == 3 : mylist.append("f") which would return a list of ["c", "d", "f"] Is something like this possible? 回答1: You misunderstand how

Matching of patterns in R

问题 I have a data.frame with two rows and 20 columns where each column holds one character, which roughly looks like this (columns scrunched here for clarity): Cols 1-20 row1 ghuytuthjilujshdftgu row2 ghuytuthjilujshdftgu I want a mechanism for comparing these two strings character by character (column by column) starting from position 10 and scanning outwards, returning the number of matching characters until the first difference is encountered. In this case it is obvious that both lines are

Powershell number notation matches and rename-item logic

由 ↘锁芯ラ 提交于 2020-01-06 08:43:46
问题 In the below solution for renaming files taken from an answer to my question Rename-Item error, what do the following bits of code do? ^\d{4} e={$Matches[1]} Rename-item -Newname {"{0:D4} - sp - C - {1}" -f ++$Count.Value,$_.Name} For 1. I think this is saying a four digit number but I would like to understand the notation used. For 2. $Matches hasn't been set anywhere, is this a variable specific to Select-Object ? For 3. what is {0:D4} doing and the {1} at the end of the same string. Also,

Spark应用监控解决方案--使用Prometheus和Grafana监控Spark应用

Spark任务启动后，我们通常都是通过跳板机去Spark UI界面查看对应任务的信息，一旦任务多了之后，这将会是让人头疼的问题。如果能将所有任务信息集中起来监控，那将会是很完美的事情。 通过S park官网指导文档 ，发现Spark只支持以下sink Each instance can report to zero or more sinks . Sinks are contained in the org.apache.spark.metrics.sink package: ConsoleSink : Logs metrics information to the console. CSVSink : Exports metrics data to CSV files at regular intervals. JmxSink : Registers metrics for viewing in a JMX console. MetricsServlet : Adds a servlet within the existing Spark UI to serve metrics data as JSON data. GraphiteSink : Sends metrics to a Graphite node. Slf4jSink : Sends metrics to slf4j
