rows

问题 I had saved the required steps for a parameterized string match query that outputs the subsequent rows. I had lost my files when transferring to a faulty drive. So... I'm trying to mash things together and this isn't working. $stmt = $link->prepare("SELECT id,entry,date from table WHERE string=? ORDER by Id DESC"); $stmt->bind_param('s',$string); $stmt->execute(); $stmt->bind_result($id_db,$entry_db,$date_db); if (($result = $link->query($stmt)) { while ($row = $result->fetch_row()){ } } I

问题 Error creating row in tableview. My table view is loaded with a json. I saw many examples here, however none were able to solve my code NSMutableArray *myArray = [NSMutableArray arrayWithArray:news]; [myArray insertObject:@"teste" atIndex:0]; NSMutableArray *path = [NSMutableArray arrayWithObject:[NSIndexPath indexPathForRow:[news count]-1 inSection:1]]; [self.tableView insertRowsAtIndexPaths:path withRowAnimation:UITableViewRowAnimationAutomatic]; [self.tableView endUpdates]; error displayed

问题 G'day everyone, I've got a Raspberry Pi system which keeps track of tools being checked out by various users. I've set it up such that a scan of the system is performed when a user checks in, as well as when they check out. By comparing the two scans, I can determine whether a tool has been taken/returned. However, I also have a Log.csv file which keeps track of which tools are currently checked out. I'm able to add to this log when a tool is checked out (no problems here), but I'm having

问题 There is a data set with leading and trailing rows that have a feature with zero value. How to drop such rows in an elegant way? # Library library(tidyverse) # 1. Input data.frame( id = c(1:10), value = c(0, 0, 1, 3, 0, 1, 2, 8, 9, 0)) # 2. Delete leading and trimming rows with 'value = 0' # ... # 3. Desired outcome data.frame( id = c(3:9), value = c(1, 3, 0, 1, 2, 8, 9)) Thanks. 回答1: An option would be library(dplyr) df1 %>% filter( cumsum(value) > 0 & rev(cumsum(rev(value)) > 0)) # id value
