问题 We have a table that looks like this: appointment_id | team_id ----------------|--------- 1001 | 1 1005 | 4 1009 | 7 In this table appointment_id is the primary index and team_id is just a regular index. The code for creating the table: CREATE TABLE `appointment_primary_teams` ( `appointment_id` int(11) NOT NULL, `team_id` int(11) NOT NULL, PRIMARY KEY (`appointment_id`), KEY `team_id` (`team_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4; However, occasionally the below code fails: // Even

问题 We have insert query in which we are trying to insert data to partitioned table by reading data from non partitioned table. Query - insert into db1.fact_table PARTITION(part_col1, part_col2) ( col1, col2, col3, col4, col5, col6, . . . . . . . col32 LOAD_DT, part_col1, Part_col2 ) select col1, col2, col3, col4, col5, col6, . . . . . . . col32, part_col1, Part_col2 from db1.main_table WHERE col1=0; Table has 34 columns, number of records in main table depends on size of input file which we

问题 Simple question: If I have a string and I want to add to it head and tail strings (one in the beginning and the other at the end), what would be the best way to do it? Something like this: std::string tmpstr("some string here"); std::string head("head"); std::string tail("tail"); tmpstr = head + tmpstr + tail; Is there any better way to do it? Thanks in advance. 回答1: If you were concerned about efficiency and wanted to avoid the temporary copies made by the + operator, then you could do:

问题 I have a document which contains an array of document (more or less complex), I would like to create 1 query which will update the element of the array based on a filter, and if no element match insert the element into the array. I tried couple of thing but nothing worked. I do not want to do 2 requests to avoid concurrency issue. Below is my document model, which model a driver with the car he owns public string Driver{ get; set; } public Cars[] OwnedCars{ get; set; } Let us suppose that I

问题 I have a list in a rdf knowledge graph in a Fuseki dataset. I can get the elements of the list with something like select ?webpage where { graph <http://datamusee.givingsense.eu/graph/webtracks> { ?track <http://erlangen-crm.org/current/P16_used_specific_object> ?content. ?content rdf:rest*/rdf:first ?webpage . } } but I would like to copy the list from the webtracks graph to another graph I doen't find how to do it either with an insert or by exporting the data with a construct and then

问题 I am currently building a word-template for a report. In this report are used red separators as part of the design. The separators are basically just images of red, curved lines. Instead of copy and pasting these separators when needing them, is there a way to store the image somewhere in the document, allowing it to be inserted with just the click of a button in the ribbon? My first bet would be to create a macro somehow that would insert the image, however that would require the image to be

问题 The way to insert a pair in a map is that: std::map<char,int> mymap; // first insert function version (single parameter): mymap.insert ( std::pair<char,int>('a',100) ); but now I'm trying to insert this in a map: map<pair<int,int>, int> map1; //(pair is the key and int is a value) I tried this: pair<int,int> p; p.first = 5; p.second = 20; map1.insert(pair<int,int>,double> (p,0)); So, how I can do it? 回答1: There are so many possibilities for this. You may choose any of the below which suits

问题 I have an tree like: tree = [[[None,1,None],2,[None,3,None]],4,[None,6,[None,7,None]]] The numbers represent the root of each node, the none represent the children that have no value. For example, the main root is 4 and [[None,1,None],2,[None,3,None]] is the sub tree on the left and this [None,6,[None,7,None]] is he sub tree on the right. The principal root on the sub tree on the left is 2 etc etc... And my problem is that I want to insert a value in this tree. For example I want to add the

问题 I have code like this: squares = [] for value in range(1, 5): squares.insert(value+1,value**2) print(squares) print(squares[0]) print(len(squares)) And the output is : [1, 4, 9, 16] 1 4 So even if I ask python to insert '1' at index '2', it inserts at the first available index. So how does 'insert' makes the decision? 回答1: From the Python3 doc: list.insert(i, x) Insert an item at a given position. The first argument is the index of the element before which to insert, so a.insert(0, x) inserts
