increment

问题 I have kept auto increment for primary key, by using auto increment option in my Table. And I stated that using hibernate. But now I want to auto increment a column which is not a primary key column using Hibernate Annotation. Please help. Thanks in advance. 回答1: Use the following annotation over the specific field @GeneratedType private int non_Primary_field 来源： https://stackoverflow.com/questions/16350938/how-to-auto-increment-a-non-primary-id-column-using-hibernate

问题 While fiddling with simple C code, I noticed something strange. Why does ICC produces incl %eax in assembly code generated for increment instead of addl $1, %eax ? GCC behaves as expected though, using add . Example code ( -O3 used on both GCC and ICC) int A, B, C, D, E; void foo() { A = B + 1; B = 0; C++; D++; D++; E += 2; } Result on ICC L__routine_start_foo_0: foo: movl B(%rip), %eax #5.13 movl D(%rip), %edx #8.9 incl %eax #5.17 movl E(%rip), %ecx #10.9 addl $2, %edx #9.9 addl $2, %ecx #10

问题 I'm trying to create a score tracker for GAA matches (Irish football). I've got it working but every time I run the app it doesn't reset the counters back to 0 and instead just continues to increment. Here's the code in my MainActivity java file: public class MainActivity extends ActionBarActivity { public static int homeGoalsCounter = 0; public static int homePointsCounter = 0; public static int awayGoalsCounter = 0; public static int awayPointsCounter = 0; Button homeGoalButton; Button

问题 imacro - I need to increase ATTR=ID: by one after each loop TAG POS=1 TYPE=SPAN ATTR=ID:ygtvlabelel92 The ID: ygtvlabelel92 must be ygtvlabelel93 after loop and ygtvlabelel94 ....etc 回答1: set !var1 1 add !var1 {{!loop}} TAG POS=1 TYPE=SPAN ATTR=ID:ygtvlabelel9{{!var1}} 回答2: //this is the JavaScript code. You have to place this code inside .js file or it will not work var macro; macro ="CODE:"; macro +="TAG POS=1 TYPE=SPAN ATTR=ID:ygtvlabelel{{counter}}"+"\n"; //set the counter var counter=92;

问题 I have a table Id|Parent|Counter --|------|------- 1| A | NULL 2| A | NULL 3| A | NULL 4| B | NULL 5| B | NULL 6| C | NULL 7| D | NULL 8| D | NULL I want to update the table such that the counter column is update (+1) as long as previous parent = parent . If not, counter =1 so: Id|Parent|Counter --|------|------- 1| A | 1 2| A | 2 3| A | 3 4| B | 1 5| B | 2 6| C | 1 7| D | 1 8| D | 2 I have about 3.5M records. I can get a select query but can get it to work with update. This is what I have:

问题 I'm using the Google Maps API to plot several points on a map. However, in the click event function below, i is always set to 4, i.e. its value after iterating the loop: // note these are actual addresses in the real page var addresses = new Array( "addr 1", "addr 2", "addr 3", "addr 4" ); for (var i = 0; i < addresses.length; i++) { geocoder.getLatLng(addresses[i], function(point) { if (point) { var marker = new GMarker(point); map.addOverlay(marker); map.setCenter(point, 13); GEvent

问题 According to http://introcs.cs.princeton.edu/java/11precedence/, post-increment operator has higher precedence than addition operator. So, for the following code: int i = 1; int j = i + i++; System.out.println(j); I would have thought that the expression assigned to j would have been evaluated as follows (with each line being a "step" in the evaluation) : i + i++ i + (1) // do post-increment operator; returns 1, and makes i = 2 (2) + (1) // do addition operator. need to get the operand i, so

问题 is there a way to implement something like this in loopback? LOCK READ INCREMENT UNLOCK I would like to keep counters as database values, each key is a counter (or a setting), and they shouldn't accessed my multiple requests at the same time. Also this should work for local requests too (no remoteHooks) Thanks 回答1: If you are using the mongoDB connector, this is supported by extended operators. MyModel.updateAll( { id: 123' }, { '$inc': { myproperty: 1 }}, // increment myproperty by 1 {

问题 I have been searching this for a while, basically I am trying to conditionally increment a list of element by another list, element-wise... my code is following, but is there a better way to do it? list comprehension, map?? I think a element-wise operator like ~+= from http://www.python.org/dev/peps/pep-0225/ would be really good, but why is it deferred? for i in range(1,len(s)): if s[i]<s[0]: s[i]+=p[i] based on some good feedbacks from you guys I have recoded to the following i=s<s[0] s[i]+

问题 Here is part of my makefile : LISTEINC = $(DEST)/file.inc $(DEST)/otherfile.inc $(DEST)/anotherfile.inc compteur = 1 $(DEST)/file: $(LISTEINC) #action $(DEST)/%.inc: $(DEST)/%.jpg ./script $< $compteur $(DEST) > $@ How to have the variable compteur at 1 for file, 2 for otherfile, 3 for anotherfile? $((compteur++)) would work in bash script, but here I really don't know what the equivalent is. I tried many combination of $$ () ++ +1 etc... Nothing worked. Anyone could help me please? 回答1: It
