I seem to have a problem with this SQL query: SELECT * FROM appts WHERE timeStart >='$timeStart' AND timeEnd <='$timeEnd' AND dayappt='$boatdate' The time is formatted as military time. The logistics is that a boat rental can be reserved at 7am til 1pm or 9am til 1pm or 9am til 5pm. If there is an appt within that range, it should return appts but it has proven to be inconsistent. If I pick 9am til 1pm, it will ignore appts that started with 7am even though it overlaps 9am-1pm. If I pick 9 to 5, it will return nothing even though it should with the 7am to 1pm. How do I make a SQL statement

How to fix strcpy so that it detects overlapping strings

由 梦想的初衷 提交于 2019-12-05 16:48:30
问题 In an interview, I was asked to write an implementation of strcpy and then fix it so that it properly handles overlapping strings. My implementation is below and it is very naive. How do I fix it so that: It detects overlapping strings and after detecting, how do we deal with the overlap and proceed? char* my_strcpy(char *a, char *b) { if (a == NULL || b == NULL) { return NULL; } if (a > b) { //we have an overlap? return NULL; } char *n = a; while (*b != '\0') { *a = *b; a++; b++; } *a = '\0'

由 喜欢而已 提交于 2019-12-05 07:49:55
I am trying to make the playing cards in my game overlap such that only the first half of a card is seen and the other half is covered by the next playing card. The only card that should be completely visible will be the last/rightmost card. I have used the following code with both framelayout and relativelayout to no avail. can anyone offer some suggestions? public int shouldShow(int numberOfCards, int card, int id) { if(card == -1) hide(id); else { findViewById(id).setBackgroundDrawable(deckimages[card]); //findViewById(id).offsetLeftAndRight(findViewById(id).getWidth()* numberOfCards / 2);

how can I overlap images half on one another from layout XML file like this image.

问题 I want to have two overlapping objects in a scene but I want to define which object should be drawn first. I have a sample of the code here: http://jsfiddle.net/sg02e5sm/1/ I'm using renderOrder = 1 for the second object to make it appear always on top of the first object (as long as they have the same Z value), but it's not working. 回答1: renderOrder does not make something appear "on top". It controls the order in which objects are rendered. If you want your 2nd plane to be "on top", you can

NVD3 Stacked Bar Chart Plus Line Overlapped

由 二次信任 提交于 2019-12-05 02:46:20
问题 I'm using NVD3's MultiChart to create a stacked bar chart plus line. I modified the multiChart models a bit to make the bars become stacked. Now the problem is that the lines are at the back of the bars such that I cannot hover over the lines to see the tooltip for line. Is there any options in NVD3 to bring the lines to front? I created the JSFiddle here: http://jsfiddle.net/n2hfN/50/ Javascript source: var margin = { top: 50, right: 50, bottom: 120, left: 70 }; var svg = "#chart svg"; var

How to identify rows that occur within a specific time frame?

问题 I have a table that contains hospital visits for patients. I am trying to flag visits that occur within 90 days of the previous visit. However, the caveat to this is that once a visit is flagged as an overlap visit, that visit should not be used to assess an overlap with another visit. Let me explain with an example. Table visitID patientid visit_date 1 23 1/12/2018 2 23 1/30/2018 3 23 4/20/2018 4 23 5/02/2018 In the example above, the patient had 4 visits. Visit 2 was within 90 days of visit

Overlap views inside Recyclerview

Hi I need to implement the layout as attached in pic. I have tried this StackOverFlow answer but the resultant view get created as attached below I need that bottom right corner to be above next cell of recyclerview. Please suggest how can make top of the cell below previous cell. It looks like you're close. The problems you're seeing here are: The offset you're using in the item decorator from the example you used isn't large enough - hence the black gaps The order in which your linear layout manager is stacking your views is from the top, which means that the row below will draw over the

R Find overlap among time periods

由 こ雲淡風輕ζ 提交于 2019-12-04 18:08:54
after a lot fo thinking and googling I could not find the solution to my problem, I hope you can help me. I have a large data frame with an ID column that can repeat more than 2 times, a start and and end date column that would make up a time period. I would like to find out, grouping by ID, if any of the time periods for that ID overlap with another one, and if so, flag it by creating a new column for example, saying if that ID has overlaps or not. Here is an example data frame already with the desired new column: structure(list(ID= c(34L, 34L, 80L, 80L, 81L, 81L, 81L, 94L, 94L), Start =
