range

问题 I'm tryint to select a subset of records, 5000 through 10000 from a join. I've gotten queries like this to work in the past, but they were slightly less complex. Here is the query I'm trying to use and if I remove the rownum/rnum references (and therefore the outer select) I receive all my records as expected so I know that logic is good. SELECT * FROM ( SELECT unique cl.riid_, rownum as rnum FROM <table 1> cl, <table 3> mil WHERE cl.opt = 0 AND (cl.st_ != 'QT' OR cl.st_ IS NULL) AND cl.hh =

问题 I am very new to CPLEX and am trying to understand a friends example so i may produce a model myself, however I am confused as to how one of the decision variables has been created. The notation is unfamiliar to me and also the fact that they are using a set of tuples as well as ranges in it's definition. Any help explaining what is going on and what the line of code does would be greatly appreciated. tuple bus{int busnumber; float capacity; string start_location; string stop_location; int

问题 In order keep a new question separate from previous I'm asking it as another question. From the info below (all in column A), I'd like to be able to count how many calls come in on a date outside of a time (or between times). For example, how many calls on 08/01/2019 where NOT from 07:00 to 23:00 using the first set of numbers ie: 6:47 The formatting of my source file is messed up, but the numbers below represent: Wed Oct 30 11:42:11 2019 Location: Some. Place Page 1 Call Details by Date and

问题 Currently when I have been calling my getFunction method I am getting nasty crash. My program compiles fine, but when I run and call this function, I get "Debug Assertion Failed!", "Expression: vector subscript out of range". Not sure how to deal with this as I haven't been doing much in c++ for a few years. void* PluginMap::getFunction(char* pguid, char* fname){ if(plugin_map.size()>0 && plugin_map.find(pguid)!=plugin_map.end()) { //plugin_map is an unorderedmap that is defined elsewhere.

问题 This is the code (now is full): HTML: <div id="content" contentEditable="true" onkeyup="highlight(this)">This is some area to type.</div> Javascript: function highlight(elem){ // store cursor position var cursorPos=document.selection.createRange().duplicate(); var clickx = cursorPos.getBoundingClientRect().left; var clicky = cursorPos.getBoundingClientRect().top; // copy contents of div var content = elem.innerHTML; var replaceStart = ''; var replaceEnd = ''; // only replace/move cursor if

问题 So in excel vba I'm trying to select a range, but a different range every time. I have a loop going, but I was wondering how I would actually write the code to change the range. This is what it would look like for a single range. Range("B7").Select Is there a way to do this with integers instead of strings such as "B7" i.e Range(i).Select I need it to select a single column. Any advice would be appreciated. Thanks 回答1: Well, if you only have to selct one Cell: Cells(y, x) But because you have

问题 I have a Postgres table with several columns of type numrange and int4range . I want to persist data in it from Java. Currently I have this data in a Java class like this: class Range<T> { private Integer minimum; private Integer maximum; // more code... } I'm using the JDBC Driver and the java.sql.* and I've tried several things, without success: pstmt.setObject(7, myObject.price()); // price() returns a Range object This gives me the following error: Can't infer the SQL type to use for an

问题 I want to index of my mysql database with elasticsearch. My datas is about datetime. I indexed my datas. I am using PHP 5.5 and Elasticsearch 2.1 and Mysql.

问题 package main import ( "fmt" ) func main() { m := make(map[int]int, 4) m[1] = 0 m[2] = 0 for k, _ := range m { i := 10 + k m[i] = 0 } fmt.Println(m) fmt.Println("len:", len(m)) } This code returns: 8 or 10 or 6 as length of map after loop. Video is here, playgroud here. I see that new added elements go into range, but can't explain why this loop stops randomly? 回答1: Spec: For statements: The iteration order over maps is not specified and is not guaranteed to be the same from one iteration to
