Here is my situation: I have 2 tables, Question and Answer tables both containing a post_date column. I want to get the count of the questions and answers for the recent 7 days whether or not the count is 0. Refer this for the desired output

I have tried the following code:

People of Stack Overflow!

Thanks for taking the time to read this question. What I am trying to accomplish is to pivot some data all from just one table. The original table has multiple datetime entries of specific events (e.g. when the customer was added add_time and when the customer was lost lost_time). This is one part of two rows of the deals table:

I want to create a view of this table. A view that has one row for each distinct date and counts the number of events at this specific time.

This is the goal (times do not match with the example!):

I have working code, like this:

So I was really ripping my hair out why two different sessions of R with the same data were producing wildly different times to complete the same task. After a lot of restarting R, cleaning out all my variables, and really running a clean R, I found the issue: the new data structure provided by vroom and readr is, for some reason, super sluggish on my script. Of course the easiest thing to solve this is to convert your data into a tibble as soon as you load it in. Or is there some other explanation, like poor coding praxis in my functions that can explain the sluggish behavior? Or, is this a bug with recent updates of these packages? If so and if someone is more experienced with reporting bugs to tidyverse, then here is a repex showing the behavior cause I feel that this is out of my ballpark.

I have a function that accepts an argument which can be either of type A or B. In case A is passed, it is converted to B for further processing internally.

To keep it simple, consider the following example using int/float to illustrate the scenario:

I have this query in ORACLE SQL:

I have been studying and learning PHP and MySQL and I have started a system that I'm developing for a friend's little school and to help me to improve my learning. I basically have in this case a table with the names of the students (tb_std) and another with the names of the teachers (tb_tch). The work is to distribute these students among the teachers in a new table, which is the way I think it will work better (tb_final).

1. I basically need each student to have a randomly chosen teacher so that the distribution is numerically even among the teachers.

In this example, I have 7 teachers and 44 students. Using SELECT query I did the operations to find out how many students would be for each teacher (add/division/mod), but how to make this draw to play in this new table I have no idea where to start.

I have a list whose elements are integers and I would like to accumulate these elements if only they share at least one value. With regard to those elements that don't share any values with the rest I would like them to stay as they are. Here is my sample date:

given the following model

I have the following tables:

My goal is SUM all the upvotes for a given authID across both tables, and for that I have the following query:
