sql - sp_MSforeachtable Abuse (Modification needed) -


recently hacked our database using sp_msforeachtable, multiline query if im right.

now question how can modify sys.sp_msforeachtable, using @command1 , other commands execute query in order drop our tables. 

xxxx=censored db name (somehow spaces in front of use)  use xxxx;   exec sp_msforeachtable "alter table ? nocheck constraint all"; exec sp_msforeachtable @command1 = "drop table ?"

then sql profiler shows: 

select @mscat = ltrim(str(convert(int, 0x0002)))  exec(n'declare hcforeachtable cursor global select ''['' + replace(schema_name(syso.schema_id), n'']'', n'']]'') + '']'' + ''.'' + ''['' + replace(object_name(o.id), n'']'', n'']]'') + '']'' dbo.sysobjects o join sys.all_objects syso on o.id = syso.object_id '          + n' objectproperty(o.id, n''isusertable'') = 1 ' + n' , o.category & ' + @mscat + n' = 0 '          + @whereand)  declare hcforeachtable cursor global select '[' + replace(schema_name(syso.schema_id), n']', n']]') + ']' + '.' + '[' + replace(object_name(o.id), n']', n']]') + ']' dbo.sysobjects o join sys.all_objects syso on o.id = syso.object_id  objectproperty(o.id, n'isusertable') = 1  , o.category & 2 = 0   exec @retval = sys.sp_msforeach_worker @command1, @replacechar, @command2, @command3, 0  create table #qtemp (   /* temp command storage */                 qnum                int             not null,                 qchar               nvarchar(2000)  collate database_default null         )

could let me know how secure these things? sql profiler showing me application name php5, register page or login panel injection..

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
