原表如下： 建表脚本： CREATE TABLE districtproducts ( district varchar(255), name varchar(255), price int(255) ); INSERT INTO districtproducts VALUES ('东北', '橘子', 100); INSERT INTO districtproducts VALUES ('东北', '苹果', 50); INSERT INTO districtproducts VALUES ('东北', '葡萄', 50); INSERT INTO districtproducts VALUES ('东北', '柠檬', 30); INSERT INTO districtproducts VALUES ('关东', '柠檬', 100); INSERT INTO districtproducts VALUES ('关东', '菠萝', 100); INSERT INTO districtproducts VALUES ('关东', '苹果', 100); INSERT INTO districtproducts VALUES ('关东', '葡萄', 70); INSERT INTO districtproducts VALUES ('关西', '柠檬', 70); INSERT

Eclipse 3.4[.x] - also known as Ganymede - comes with this new mechanism of provisioning called p2 . "Provisioning" is the process allowing to discover and update on demand some parts of an application, as explained in general in this article on the Sun Web site . Eclipse has an extended wiki section in which p2 details are presented. Specifically, it says in this wiki page that p2 will look for new components However after reading it. I suppose (but you may confirm that point by your own experience), that p2 can function file "file://" protocol, which would allow it to provision with local

I have built an Eclipse RCP application (Indigo) with Tycho. The build is run on a Win 7, 64-bit machine.

题目传送门 sol1: 用bitset来维护，其实感觉挺暴力的，不怎么会用bitset，借着这道题学习一下。 bitset暴力维护 #include "bits/stdc++.h" #define debug puts("what the fuck"); using namespace std; const int MAXN = 1010; char s[MAXN]; bitset<1010> bs[2][MAXN]; int main() { int n, m, q; scanf("%d%d", &n, &m); for (int i = 1; i <= n; i++) { scanf("%s", s + 1); for (int j = 1; s[j]; j++) bs[s[j] ^ '0'][j][i] = 1; } scanf("%d", &q); for (int i = 1; i <= q; i++) { scanf("%s", s + 1); bitset<1010> res; res.set(); for (int j = 1; s[j]; j++) { if (s[j] == '_') continue; res &= bs[s[j] ^ '0'][j]; } printf("%d\n", res.count()); } return 0; } sol2:

p2 has a query language that allows to run queries on the content of a p2 repository. However all examples in the documentation assume that the query language is used from within Java, e.g. IQuery<IInstallableUnit> q = QueryUtil.createMatchQuery("this.id == $0", id); metadataRepository.query(q); How can I execute a query from the command line (without writing my own Java application)? The p2 director application has an option to list or query the content of the given p2 repositories. With -list you'd get all units, and with -list Q:<p2 QL collection query> you can query for a subset. The

Simple usecase : assemble an Eclipse product using simple scripts, just dumping bundles into the plugins dir . This used to work with 3.3 - with 3.5 it's broken: my application doesn't start as the app plugin is not found. Question : what's the easiest way to fix that? This seems to be the only pain in the whole upgrade process for me. Attempts : I guess this is a no-no for P2: it maintains the bundles.info file instead, which is probably very smart.. a bit too smart for me. Some ideas I had: can I just skip P2 altogether and get back to plain old, simple -dirty- discovery mechanism? can I set
