  • How do i know if a mysql table is using myISAM or InnoDB Engine

    - by kamal
    I want to confirm if the statement below is indeed true: There is no way to specify a storage engine for a certain database, only for single tables, You can, however, specify a storage engine to be used during one session with: SET storage_engine=InnoDB; so you don't have to specify it for each table. How do i confirm, if indeed all the tables are using InnoDB All the tables were using myISAM.

  • What is the cost of object creating.

    - by Tony

Thanks

  • Oracle - Return shortest string value in a set of rows

    - by Sridhar
    Hi, I'm trying to write a query that returns the shortest string value in the column. For ex: if ColumnA has values ABCDE, ZXDR, ERC, the query should return "ERC". I've written the following query, but I'm wondering if there is any better way to do this? BTW, the query should return a single value. select distinct ColumnA from ( select ColumnA, rank() over (order by length(ColumnA), ColumnA) len_rank from TableA where ColumnB = 'XXX' ) where len_rank <= 1 Thank you.

  • nodejs async.waterfall method

    - by user1513388
    Update 2 Complete code listing var request = require('request'); var cache = require('memory-cache'); var async = require('async'); var server = '172.16.221.190' var user = 'admin' var password ='Passw0rd' var dn ='\\VE\\Policy\\Objects' var jsonpayload = {"Username": user, "Password": password} async.waterfall([ //Get the API Key function(callback){ request.post({uri: 'http://' + server +'/sdk/authorize/', json: jsonpayload, headers: {'content_type': 'application/json'} }, function (e, r, body) { callback(null, body.APIKey); }) }, //List the credential objects function(apikey, callback){ var jsonpayload2 = {"ObjectDN": dn, "Recursive": true} request.post({uri: 'http://' + server +'/sdk/Config/enumerate?apikey=' + apikey, json: jsonpayload2, headers: {'content_type': 'application/json'} }, function (e, r, body) { var dns = []; for (var i = 0; i < body.Objects.length; i++) { dns.push({'name': body.Objects[i].Name, 'dn': body.Objects[i].DN}) } callback(null, dns, apikey); }) }, function(dns, apikey, callback){ // console.log(dns) var cb = []; for (var i = 0; i < dns.length; i++) { //Retrieve the credential var jsonpayload3 = {"CredentialPath": dns[i].dn, "Pattern": null, "Recursive": false} console.log(dns[i].dn) request.post({uri: 'http://' + server +'/sdk/credentials/retrieve?apikey=' + apikey, json: jsonpayload3, headers: {'content_type': 'application/json'} }, function (e, r, body) { // console.log(body) cb.push({'cl': body.Classname}) callback(null, cb, apikey); console.log(cb) }); } } ], function (err, result) { // console.log(result) // result now equals 'done' }); Update: I'm building a small application that needs to make multiple HTTP calls to a an external API and amalgamates the results into a single object or array. e.g. Connect to endpoint and get auth key - pass auth key to step 2 Connect to endpoint using auth key and get JSON results - create an object containing summary results and pass to step 3. Iterate over passed object summary results and call API for each item in the object to get detailed information for each summary line Create a single JSON data structure that contains the summary and detail information. The original question below outlines what I've tried so far! Original Question: Will the async.waterfall method support multiple callbacks? i.e. Iterate over an array thats passed from a previous item in the chain, then invoke multiple http requests each of which would have their own callbacks. e.g, sync.waterfall([ function(dns, key, callback){ var cb = []; for (var i = 0; i < dns.length; i++) { //Retrieve the credential var jsonpayload3 = {"Cred": dns[i].DN, "Pattern": null, "Recursive": false} console.log(dns[i].DN) request.post({uri: 'http://' + vedserver +'/api/cred/retrieve?apikey=' + key, json: jsonpayload3, headers: {'content_type': 'application/json'} }, function (e, r, body) { console.log(body) cb.push({'cl': body.Classname}) callback(null, cb, key); }); } }

  • Two Persistence Units, Two entityManagerFactory(s), SPring, JPA, Hibernate

    - by sebajb
    I am using Two entityManagerFactory{1,2} based on two persistence units, autowired through spring, hibernate, with resource local. My DaoImpls are configured with the PersistenceUnit(unitName='...') according to the unit needed. I was under the impression that using them with the unitName specified would allow me to use x number of PUs without problem but I still get: expected single matching bean but found two: [emf1, emf2]. Am I missing some other configuration?

  • HTTPS only on specific page with .htaccess

    - by JamWaffles
    Hi all I have a URL such as http://www.domain.com/index.php?p=register. I want to redirect that to use HTTPS (SSL) with .htaccess, but only on this, and a couple of other pages (the login page, etc), but not the entire site. The URLs don't point to directories, but are used to dynamically include different files. Can someone give me a pointer or an example of how to get a single page redirect to HTTPS please? Thanks, James

  • How to get only the first row from a java.sql.ResultSet?

    - by llm
    I have a ResultSet object containing all the rows returned from an sql query. I want to be able to (in the java code, NOT force it in the SQL) to be able to take a ResultSet and transform it so that it only contains 1 (the first) row. What would be the way to acheive this? Also, is there another appropriate class (somewhere in java.sql or elsewhere) for storing just a single row rather than trimming my ResultSet? Thanks!

  • Mercurial & Windows Server 2003

    - by tjsimmons
    Hi all, I just set up Mercurial on our main webserver, hosting repositories via hgwebdir.cgi. The problem I'm having now is when I run hg push from my local machine to the server's repository, it takes an absolutely ridiculous amount of time to push a very small directory, with only a single changeset. Is it possible that I've set something up wrong? I keep getting HTTP Error 502: Bad Gateway. Thanks!

  • Mysql - Rank field for a query

    - by Mark
    How can I add a field that contains a rows rank within the result set of a query? Initially I used php to rank my results as it was all on a single page. Now I have added multiple pages so now even though I am on the second page the first result on the page is still '1st'. Obviously I could multiply the page number by the number of results per page and add the result number but I imagine there is a better way within the query. Thanks,

  • Well tested C/C++ lock free queue?

    - by uj
    I am looking for a well-tested, publicly available C/C++ implementation of a lock free queue. I need at least multiple-producers/single-consumer functionality. Multiple-consumers is even better, if exists. I'm targetting VC's _Interlocked... intrinsics, though anything which is straight forward to port would be fine. Could anyone give any pointers?

  • Is there a preferred method of including the source code(s) of other software you've used in your ap

    - by Adam S
    I've used a few F/OSS libraries in my commercial application. As per their licenses, I am obligated to include their source codes along with my VS2008 application. This is my first time making a "real" commercial application, and I would appreciate some advice on how best to go about including their source codes. I don't want to package them as zip files alongside my installed. I still want my installer to be a single file.
