问题 so we have the mysql MIN() function for getting the minimum in a table...but what if I want to get a MIN() based on a criteria so something like MIN(age) WHERE height < 170 in which the aim is to get the minimum age of ONLY people whose height is < 170...so say sam is the youngest of those with height < 170, but pam is younger than sam but have height > 170, then the query should return sam instead of pam... how would I compose such query? 回答1: You say you want the "minimum age of ONLY people

This question already has answers here : Closed 8 years ago . Possible Duplicate: How to select min and max values of a column in a datatable? I am searching for code that could find the min and max (or first and last values) from a column in a datatable. I have stored the datatable with four column values I want to find the min and max values from the third column(index 2) and display it to the user. I tried many ways but all are causing exceptions... Last i tried this code but even this is not working.. count = Convert.ToInt32(dt.Rows.Count); start = Convert.ToInt32(dt.Rows[0][2].ToString())

I try to get the max value of a mysql select, but want to have it null/empty/0 if there is one row containing no timestamp. Table stats (simplyfied): ID CLIENT ORDER_DATE CANCEL_DATE 1 5 1213567200 2 5 1213567200 3 6 1210629600 1281736799 4 6 1210629600 1281736799 5 7 1201042800 1248386399 6 7 1201042800 7 8 1205449200 1271282399 I'm now looking to get the lowest order date (no problem, as it is never empty), and the maximum cancel date. If the client has already cancelled his subscription, the cancel date is filled, but if he is still active, there is no cancel date at all. Query: SELECT ID,

Find max value in java from file input

阅读更多关于 Find max value in java from file input

问题 I'm new to Java and I am trying to write a program that asks the user to input the name of a txt file containing only numbers, and the program will output the sum, average, max, and min of the numbers in the file. I have written most of the program, however I am stuck trying to find the max and min of the values. Any information you can give would be helpful, and if I was not clear enough I can try to elaborate. My code so far is: public class NumberFile{ public static void main(String[] args

How to Determine the Max and Min Values Read in From a Text File in Java

阅读更多关于 How to Determine the Max and Min Values Read in From a Text File in Java

问题 I am doing a homework assignment for a class, and am looking for some helpful pointers, not full solutions. Basically, I have to write a Java program that reads in a text file and lists the information line by line, lists the line number, and finally, prints out the maximum and minimum value and the years that relates to each. The text file contains a year and the temperature for that year. So, it lists something like, "1900 50.9." I am not meant to use an array, or the scanner, this is part

Elegant way to extract a tuple from list of tuples with minimum value of element

阅读更多关于 Elegant way to extract a tuple from list of tuples with minimum value of element

问题 I am having list of tuple from which I want the tuple with the minimum value at index 1 . For example, if my list is like: a =[('a', 2), ('ee', 3), ('mm', 4), ('x', 1)] I want the returned tuple to be ('x', 1) . Currently I am using sorted function to get this result like: min=sorted(a, key=lambda t: t[1])[0] Is there better ways to do it? Maybe with min function? 回答1: You may use min() function with key parameter in order to find the tuple with minimum value in the list. There is no need to

Index from accumarray with max/min

阅读更多关于 Index from accumarray with max/min

问题 I have a vector and a cell array (with repeating strings) with the same size. The cell array defines the groups. I want to find min/max values in the vector for each group. For example: value = randperm(5) %# just an example, non-unique in general value = 4 1 2 3 5 group = {'a','b','a','c','b'}; [grnum, grname] = grp2idx(group); I use ACCUMARRAY function for this: grvalue = accumarray(grnum,value,[],@max); So I have new cell array with unique group name ( grname ) and new vector ( grvalue ).

Return tuple with smallest y value from list of tuples

阅读更多关于 Return tuple with smallest y value from list of tuples

I am trying to return a tuple the smallest second index value (y value) from a list of tuples. If there are two tuples with the lowest y value, then select the tuple with the largest x value (i.e first index). For example, suppose I have the tuple: x = [(2, 3), (4, 3), (6, 9)] The the value returned should be (4, 3) . (2, 3) is a candidate, as x[0][1] is 3 (same as x[1][1] ), however, x[0][0] is smaller than x[1][0] . So far I have tried: start_point = min(x, key = lambda t: t[1]) However, this only checks the second index, and does not compare two tuples first index if their second index's

min/max of collections containing NaN (handling incomparability in ordering)

阅读更多关于 min/max of collections containing NaN (handling incomparability in ordering)

I just ran into a nasty bug as a result of the following behavior: scala> List(1.0, 2.0, 3.0, Double.NaN).min res1: Double = NaN scala> List(1.0, 2.0, 3.0, Double.NaN).max res2: Double = NaN I understand that for a pairwise comparison it may sometimes be preferable to have max(NaN, 0) = NaN and this is probably the reason why java.lang.Double.compare follows this convention (there seems to be an IEEE standard for that). For a collection however, I really think that this is a strange convention. After all the above collection does contain valid numbers; and these numbers have a clear maximum
