java - Counting rows sql table with jdbc -


i have trouble counting rows of sqltable. using query in ms studio works fine when try in java sql exception:

connection con = null;     statement stat = null;     int result = 0;     int i;     try {         con = drivermanager.getconnection("jdbc:sqlserver://localhost:1433;user=sa;password=123456; databasename=rpa;");         stat = con.createstatement();         result = stat.executeupdate("select count(*) rpa_users");      }catch (sqlexception e) {         system.out.println("cannot connect!");         e.printstacktrace();     } {         if (con != null) {             try {                 con.close();             } catch (sqlexception e) {                 e.printstacktrace();             }         }     }     return result;

could explain me i'm doing wrong? in advance

edit: nevermind found guys, usual help! solution if interested:

result = stat.executequery("select count(*) /tablename/");          result.next();         rowcount = result.getint(1);

use executequery instead of executeupdate issuing database read queries

result = stat.executequery("select count(*) rpa_users");

aside: consider using prepared statements

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
