hi new database. trying figure out way find procedure dependent on procedure. below query giving me dependecy of proc1. ie procedure called proc1 select referenced_name user_dependencies name = 'proc1' ; below things want know: 1) query work same function. ? 2) query recursive ie proc1 calls-> proc2 calls ->proc3 calls -> proc4 ie: when call query proc1 whill give dependency or 1 level dependency(ie proc2). 3) if procedure inside package find dependency should query ? yes no, shows level of dependency user_dependencies shows dependency @ package level, not individual procedures , functions within package. pl/scope (introduced in 11g) allows find usages @ procedure/function level within package, works if it's enabled when code compiled.

how insert indian rupees symbol in database (oracle 10g, mysql 5.0 , sql server 2008)? actually had 1 table "currency" , in 2 field "currencyname" , "currencysymbol", how insert new rupees symbol in databse. there's nothing special ₹ (u+20b9 new rupee symbol), except that, being new, there 0 font support it. if you've got database connection supports unicode, can store other character: insert currency (name, symbol) values ('inr', '₹'); (you want use nvarchar storage , n'₹' in sql server.) if haven't got unicode-safe connection (for example you're using crap tool windows console) have work around using eg. values ('inr', char(226, 130, 185)) for utf-8-collated column in mysql, or nchar(8377) unicode column in sql server.

i trying spawn thread in rails. not comfortable using threads need have in-depth knowledge of rails' request/response cycle, yet cannot avoid using 1 request times out. in order avoid time out, using thread within request. question here simple. thread i've used accesses params[] variable inside it. , things seem work ok now. want know whether right? i'd happy if can throw light on using threads in rails during request/response cycle. [starting bounty] the short answer yes, degree; binding in thread created continue persist. params still exist if no 1 (including rails) goes out of way modify or delete params hash. instead, rely on garbage collector clean these objects. since thread has access current context (called "binding" in ruby) when created, variables can reached scope (effectively entire state when thread created) cannot deleted garbage collector. however, executing continues in main thread, values of variables in context can changed main t...

what difference between these 3 forms: this $this $(this) in typical usage you'll see them (the $this usage may vary): this - refers dom element in handler you're on, may object entirely in other situations, it's context. $this - created var $this = $(this) cached version of jquery wrapped version efficiency (or chain off $(this) same in many cases). $(this) - jquery wrapped version of element, have access all methods (the ones in $.fn specifically).

i need create script run on command line using php , want take advantage of zf , models (classes) have written using it. how do elegantly possible? you have duplicate code of public/index.php without calling run method of zend_application (which mvc stuff) , load resources need. #!/usr/bin/php <?php define('application_path', realpath(dirname(__file__) . '/../application')); set_include_path(realpath(application_path . '/../library')); require_once 'zend/application.php'; $application = new zend_application( application_env, application_path .

i'm adding admob ads (say 5 times fast) finished, published android app. added code pdf included admob, following instructions tee. test ads show fine on emulators , specified test devices. don't appear in published marketplace app when download , run it. still impressions on admob page however. ideas? admob doesn't have ads display. worse apps others. there few things mitigate problem: enable adsense ads - gives larger pool of ads ensure have house ads available of apps in admob. way, if can't find paying ads, they'll @ least show house ads. raise fill rate, not directly raise income (depends on house ads).

assumptions: microsoft stack (asp.net; sql server). some content management systems handle user-generated content (images, file attachments) storing in file system. others store these items in end database. some examples of both: in filesystem: community server, graffiti cms in database: microsoft sharepoint i can see pros , cons of each approach. in filesystem lightweight avoids bloating database backup , restore potentially simpler in database all content in 1 repository (the database) complete separation of concerns (content vs format) easier deployment of web site (e.g. directly subversion repository) what's best approach, , why? pros , cons of keeping user files in database? there approach? i'm making question community wiki because subjective. if using sql server 2008 or higher, can use filestream functionality best of both worlds. is, can access documents database (for queries, etc), still have access file via file system (usin...
