问题 This question already has answers here : php remove duplicates from array (5 answers) Closed 6 years ago . How do I remove duplicates from an array? Let's say that my I have two arrays named $array and $new_array . $array has contents while $new_array is empty, as seen below: $array = array(5,1,2,1,5,7,10); $new_array = array(); I want $new_array to store the unique values of $array . It kind of goes like this: $array = array(5,1,2,1,5,7,10); $new_array = array(5,1,2,7,10); // removing the 1

问题 I have a table company with 60 columns. The goal is to create a tool to find, compare and eliminate duplicates in this table. Example: I find 2 companies that potentially are the same, but I need to know which values (columns) differ between these 2 rows in order to continue. I think it is possible to compare column by column x 60, but I search for a simpler and more generic solution. Something like: SELECT * FROM company where co_id=22 SHOW DIFFERENCE SELECT * FROM company where co_id=33 The

问题 Duplicates appear in the database after fetching. Below are the mapping and the fetch code: +(RKEntityMapping *)userMapping:(RKEntityMapping *)userMapping { [userMapping addAttributeMappingsFromDictionary:@{ @"userid" : @"userid", @"firstName" : @"firstName", @"lastName" : @"lastName", }]; userMapping.identificationAttributes = @[@"userid"]; return userMapping; } Fetch Code: AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; self.objectManager = [self

问题 I need to create one list based on two other lists. But seems like it does not remove the duplicates. Is this efficient way of merging two lists with no dupes? List<String[]> blocksComparisonSet1 = new List<String[]>(); List<String[]> blocksComparisonSet2 = new List<String[]>(); //we will combine list1 and list2 into this one List<String[]> blocksComparisonFinal = new List<String[]>(); //this is how I store data in each list //if both values found, add both of them (partial functions, FYI)

问题 I am trying to create a subroutine to delete duplicates out of comboboxes. I input a number in place of X when I called the subroutine. I keep getting an error that tells me "Object Required" when i get to the subroutine. I know that means that something is not being properly initialized, but I cannot figure out how to fix my issue. Any help would be greatly appreciated. Thank you. Private Sub UserForm_Initialize() 'ComboBox Populate Dim rngNext As Range Dim myRange As Range Dim C As Integer

问题 I have read some partially solutions on my problem but unfortunately I've come up for questioning. So here's my question. I have an array var = results[1,2,2,3,1,3] . I have to print/echo all the values and the final values should be display the value of 1,2,3 . I've read about finding values that has a duplicate but this might not work on mine since it only returns duplicate values . I've read about filtering unique values but of course it will only show me a unique value and won't show me

问题 Table 1: ID Values 1 1 2 2 3 3 4 4 Table 2: ID Values 1 1 1 2 1 2 2 4 4 5 4 6 I need a result to be: ID Table 1 Values Table 2 Values 1 1 1 2 2 4 3 3 *This is blank because Table 2 doesn't have ID 3 4 4 5 4 4 6 Notice the Exclusion of the rows in table 2 Where the Values are duplicated ( ID 1 and Value 2). Yet the 2 rows for ID 4 because both values from Table 2 for ID 4 do not have duplicity. So this is a left join and I want only the Value from table 2 where that Value is not duplicated AND
