  • how to properly set environment variables

    - by avorum
    I've recently started using Windows (having used Ubuntu up until now) and I find myself unable to properly set environment variables. Whenever I set them they don't seem to work. I've been going to Start-Edit Environment Variables for your Account and editing the PATH value in the upper half of the GUI. Here's what I've got so far. ;C:\Chocolatey\bin;C:\tools\mysql\current\bin;C:\Program Files (x86)\Git\bin;C:\Program Files\MySQL\MySQL Server 5.6\bin\;C:\Python33\Scripts; These are each the parent directories of the executables I'd like to be able to run by name from CMD, but mysql, git, and pip aren't being recognized. Am I doing something wrong syntactically or at a general understanding level? I'd like to be able to run these commands without having to specify the full path to the executables every time. EDIT: The full PATH extracted from CMD PATH=C:\Python33\;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMD APP\bin\x86;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\GTK2-Runtime\bin;C:\Program Files\WIDCOMM\Bluetooth Software\;C:\Program Files\WIDCOMM\Bluetooth Software\syswow64;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\;C:\Program Files (x86)\Java\jre7\bin;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;C:\Program Files (x86)\Microsoft SDKs\TypeScript\;C:\Program Files (x86)\MySQL\MySQL Utilities 1.3.4\; ;C:\Chocolatey\bin;C:\tools\mysql\current\bin I'm being forced to use Windows by my work environment, I don't enjoy the state of affairs.

  • Ubuntu upgrade process failed

    - by Spin0us
    I tried to dist-upgrade my ubuntu server on my percona cluster but it failed with this message The following packages have unmet dependencies: libmysqlclient18 : Depends: libmariadbclient18 (= 5.5.33a+maria-1~precise) but it is not installable And here is the package listing # dpkg --list | grep -E 'percona|mysql' ii libdbd-mysql-perl 4.020-1build2 Perl5 database interface to the MySQL database iU libmysqlclient18 5.5.33a+maria-1~precise Virtual package to satisfy external depends ii mariadb-common 5.5.33a+maria-1~precise MariaDB database common files (e.g. /etc/mysql/conf.d/mariadb.cnf) ii percona-xtrabackup 2.1.5-680-1.precise Open source backup tool for InnoDB and XtraDB ii percona-xtradb-cluster-client-5.5 5.5.31-23.7.5-438.precise Percona Server database client binaries ii percona-xtradb-cluster-common-5.5 5.5.33-23.7.6-496.precise Percona Server database common files (e.g. /etc/mysql/my.cnf) ii percona-xtradb-cluster-galera-2.x 157.precise Galera components of Percona XtraDB Cluster ii percona-xtradb-cluster-server-5.5 5.5.31-23.7.5-438.precise Percona Server database server binaries ii php5-mysql 5.3.10-1ubuntu3.8 MySQL module for php5 During the install of the server, mariadb and galera cluster have first been installed.

  • use ssh tunnel with phpmyadmin

    - by JohnMerlino
    I been using ssh tunnel to bypass firewall of remote mysql server. On my Ubuntu 12.04 installation, it works via the terminal and it works when using a program called mysql workbench. However, that program freezes often and I want to try phpmyadmin as an alternative. However, I cannot connect to remote server using ssh tunnel on phpmyadmin, albeit I can connect locally. These are the steps I've tried: 1) Open a tunnel, listening on localhost:3307 and forwarding everything to xxx.xxx.xxx.xxx:3306 (used 3307 because MySQL on my local machine uses the default port 3306): ssh -L 3307:localhost:3306 [email protected] So now I have the port for tunnel open and I have my local mysql installation default port: $ netstat -tln Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:3307 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN ... 2) Now I can easily connect to remote server via localhost using the terminal: $ mysql -u user.name -p -h 127.0.0.1 -P 3307 Notice that I expicitly identify 3307 as the port, so traffic forwards to the remote server, and hence it logs me in to the remote server. Unfortunately, the localhost/phpmyadmin local login interface doesn't allow you to specify a port option. So I modify the config-db.php file and change the $dbport variable to 3307, under the impression that the phpmyadmin interface will now work with port 3307: $ sudo vim /etc/phpmyadmin/config-db.php $dbport='3307'; Then I restart the mysql server. Unfortunately, it didn't work. When I use the remote credentials to login, it gives me error: #1045 Cannot log in to the MySQL server

  • Hibernate: Perform criteria query with Sub-Select AND Left-Outer join?

    - by Markos Fragkakis
    Can I perform a Criteria query with Sub-Select AND Left-Outer join? For example, I have A 1-many B 1-many C. With Criteria.createAlias ("b", "b", Criteria.LEFT_JOIN) I can perform Left Outer join. With Criteria.setFetchMode ("b", org.hibernate.FetchMode.DEFAULT) I can perform Join with the default fetching strategy. I assume that having set @org.hibernate.annotations.FetchMode.SUBSELECT in both A.B and B.C is enough (is it?). Question 1: Why does org.hibernate.FetchMode not have SUBSELECT option, whereas the org.hibernate.annotations.FetchMode does? Question 2: Can I perform a Criteria query with Sub-Select AND Left-Outer join?

  • Outer Join is not working in Linq Query: The method 'Join' cannot follow the method 'SelectMany' or is not supported

    - by Scorpion
    I am writing the Linq query as below: But on run its throwing the following error: The method 'Join' cannot follow the method 'SelectMany' or is not supported. Try writing the query in terms of supported methods or call the 'AsEnumerable' or 'ToList' method before calling unsupported methods. LINQ from a in AccountSet join sm in new_schoolMemberSet on a.AccountId equals sm.new_OrganisationId.Id into ps from suboc in ps.DefaultIfEmpty() join sr in new_schoolRoleSet on suboc.new_SchoolRoleId.Id equals sr.new_schoolRoleId where sr.new_name == "Manager" where a.new_OrganisationType.Value == 430870007 select new { a.AccountId, a.new_OrganisationType.Value } I am expecting the result as below: I never used the Outer join in Linq before. So please correct me if I am doing it wrong. Thanks

  • LINQ 4 XML - What is the proper way to query deep in the tree structure?

I would like to do a LINQ query against a class set that was deserialized from this XML. For instance: ToAddress = [email protected] FromAddress = [email protected] Query: Get EmailRule.Include(Parse).Include(TargetPST) where address == ToAddress AND Parse.ToAddress==true AND Parse.useJustDomain==false Get EmailRule.Include(Parse).Include(TargetPST) where address == [ToAddress Domain Only] AND Parse.ToAddress==true AND Parse.useJustDomain==true Get EmailRule.Include(Parse).Include(TargetPST) where address == FromAddress AND Parse.FromAddress==true AND Parse.useJustDomain==false Get EmailRule.Include(Parse).Include(TargetPST) where address == [FromAddress Domain Only] AND Parse.FromAddress==true AND Parse.useJustDomain==true I am having a hard time figuring this LINQ query out. I can, of course, loop on all the bits in the XML like so (includes deserialization into objects): XmlSerializer s = new XmlSerializer(typeof(EmailRuleList)); TextReader r = new StreamReader(path); _emailRuleList = (EmailRuleList)s.Deserialize(r); TargetPST[] PSTList = _emailRuleList.Items; foreach (TargetPST targetPST in PSTList) { olRoot = GetRootFolder(targetPST.name); if (olRoot != null) { Parse[] ParseList = targetPST.Items; foreach (Parse parseRules in ParseList) { EmailRule[] EmailRuleList = parseRules.Items; foreach (EmailRule targetFolders in EmailRuleList) { } } } } However, this means going through all these loops for each and every address. It makes more sense to me to query against the Objects. Any tips appreciated!

  • Silverlight RIA Services. Query fails on large table but works with Where clause

    - by FauxReal
    I have a somewhat large table, maybe 2000 rows by 50 columns. When using the most basic imaginable RIA implementation. Create one-table Model Create DomainService Drop datagrid onto MainPage.xaml Drop datasource onto datagrid Ctrl-F5 I get this error: System.ServiceModel.DomainServices.Client.DomainOperationException: Load operation faild for query. Value cannot be null. Error is much larger, but thats the beginning of it. The weird thing is that if I narrow the results down with a where clause on the GetQuery, it works fine. In fact six different querys which together result in all of the rows being called works fine also. So basically, I'm sure its not some sort of rogue row. Why do I get this "Value cannot be null" error if I query the whole table? Thanks

  • linq query - The method or operation is not implemented.

    I'm doing the Rob Conery mvc storefront and at one place I'm suppose to get categories but I get an error with this linq query and I can not get why. It's exactly the same as his. var culturedName = from ct in ReadOnlyContext.CategoryCultureDetails where ct.Culture.LanguageCode == System.Globalization.CultureInfo.CurrentUICulture.TwoLetterISOLanguageName select new { ct.CategoryName, ct.CategoryId }; return from c in ReadOnlyContext.Categories join cn in culturedName on c.CategoryId equals cn.CategoryId select new Core.Model.Category { Id = c.CategoryId, Name = cn.CategoryName, ParentId = c.ParentId ?? 0, Products = new LazyList<Core.Model.Product>(from p in GetProducts() join cp in ReadOnlyContext.Categories_Products on p.Id equals cp.ProductId where cp.CategoryId == c.CategoryId select p) }; its the return query that mess things up. I have checked and the culturename actually gets data from the database. Appricate your help

  • Flex+JPA/Hibernate+BlazeDS+MySQL how to debug this monster?!

    - by Zenzen
    Ok so I'm making a "simple" web app using the technologies from the topic, recently I found http://www.adobe.com/devnet/flex/articles/flex_hibernate.html so I'm following it and I try to apply it to my app, the only difference being I'm working on a Mac and I'm using MAMP for the database (so no command line for me). The thing is I'm having some trouble with retrieving/connecting to the database. I have the remoting-config.xml, persistance.xml, a News.java class (my Entity), a NewsService.java class, a News.as class - all just like in the tutorial. I have of course this line in one of my .mxmls: <mx:RemoteObject id="loaderService" destination="newsService" result="handleLoadResult(event)" fault="handleFault(event)" showBusyCursor="true" /> And my remoting-config.xml looks like this (well part of it): <destination id="newsService"> <properties><source>com.gamelist.news.NewsService</source></properties> </destination> NewsService has a method: public List<News> getLatestNews() { EntityManagerFactory emf = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT); EntityManager em = emf.createEntityManager(); Query findLatestQuery = em.createNamedQuery("news.findLatest"); List<News> news = findLatestQuery.getResultList(); return news; } And the named query is in the News class: @Entity @Table(name="GLT_NEWS") @NamedQueries({ @NamedQuery(name="news.findLatest", query="from GLT_NEWS order by new_date_added limit 5 ") }) The handledLoadResult looks like this: private function handleLoadResult(ev:ResultEvent):void { newsList = ev.result as ArrayCollection; newsRecords = newsList.length; } Where: [Bindable] private var newsList:ArrayCollection = new ArrayCollection(); But when I try to trigger: loaderService.getLatestNews(); nothing happens, newsList is empty. Few things I need to point out: 1) as I said I didn't install mysql manually, but I'm using MAMP (yes, the server's running), could this cause some trouble? 2) I already have a "gladm" database and I have a "GLT_NEWS" table with all the fields, is this bad? Basically the question is how am I suppose to debug this thing so I can find the mistake I'm making? I know that loadData() is executed (did a trace()), but I have no idea what happens with loaderService.getLatestNews()... @EDIT: ok so I see I'm getting an error in the "fault handler" which says "Error: Client.Error.MessageSend - Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 404: url: 'http://localhost:8080/WebContent/messagebroker/amf' - "

  • (Oracle Performance) Will a query based on a view limit the view using the where clause?

    - by BestPractices
    In Oracle (10g), when I use a View (not Materialized View), does Oracle take into account the where clause when it executes the view? Let's say I have: MY_VIEW = SELECT * FROM PERSON P, ORDERS O WHERE P.P_ID = O.P_ID And I then execute the following: SELECT * FROM MY_VIEW WHERE MY_VIEW.P_ID = '1234' When this executes, does oracle first execute the query for the view and THEN filter it based on my where clause (where MY_VIEW.P_ID = '1234') or does it do this filtering as part of the execution of the view? If it does not do the latter, and P_ID had an index, would I also lose out on the indexing capability since Oracle would be executing my query against the view which doesn't have the index rather than the base table which has the index?

  • Is this sufficient to prevent query injection while using SQL Server?

    - by Derek Adair
    Hi, I have recently taken on a project in which I need to integrate with PHP/SQL Server. I am looking for the quickest and easiest function to prevent SQL injection on SQL Server as I prefer MySQL and do not anticipate many more SQL Server related projects. Is this function sufficient? $someVal = mssql_escape($_POST['someVal']); $query = "INSERT INTO tblName SET field = $someVal"; mssql_execute($query); function mssql_escape($str) { return str_replace("'", "''", $str); } If not, what additional steps should I take?

  • SQL 05 full-text query fails "Specified module could not be found."

    - by Dan Bailiff
    I'm running SQL 2005 on Windows XP. I have a database table that has full text searching enabled. I was able to build and even re-build the index. However, when I try to query it like this: Select * from fulltext_english WHERE CONTAINS(page_data, 'causes') I get this error: Msg 7619, Level 16, State 1, Line 1 The execution of a full-text query failed. "The specified module could not be found." Did I miss something on the install? Is this a dll issue? I've googled and binged for days and can't find anything similar to this message. Thanks!

  • How to salvage SQL server 2008 query from KILLED/ROLLBACK state?

    - by littlegreen
    I have a stored procedure that inserts batches of millions of rows, emerging from a certain query, into an SQL database. It has one parameter selecting the batch; when this parameter is omitted, it will gather a list of batches and recursively call itself, in order to iterate over batches. In (pseudo-)code, it looks something like this: CREATE PROCEDURE spProcedure AS BEGIN IF @code = 0 BEGIN ... WHILE @@Fetch_Status=0 BEGIN EXEC spProcedure @code FETCH NEXT ... INTO @code END END ELSE BEGIN -- Disable indexes ... INSERT INTO table SELECT (...) -- Enable indexes ... Now it can happen that this procedure is slow, for whatever reason: it can't get a lock, one of the indexes it uses is misdefined or disabled. In that case, I want to be able kill the procedure, truncate and recreate the resulting table, and try again. However, when I try and kill the procedure, the process frequently oozes into a KILLED/ROLLBACK state from which there seems to be no return. From Google I have learned to do an sp_lock, find the spid, and then kill it with KILL <spid>. But when I try to kill it, it tells me SPID 75: transaction rollback in progress. Estimated rollback completion: 0%. Estimated time remaining: 554 seconds. I did find a forum message hinting that another spid should be killed before the other one can start a rollback. But that didn't work for me either, plus I do not understand, why that would be the case... could it be because I am recursively calling my own stored procedure? (But it should be having the same spid, right?) In any case, my process is just sitting there, being dead, not responding to kills, and locking the table. This is very frustrating, as I want to go on developing my queries, not waiting hours on my server sitting dead while pretending to be finishing a supposed rollback. Is there some way in which I can tell the server not to store any rollback information for my query? Or not to allow any other queries to interfere with the rollback, so that it will not take so long? Or how to rewrite my query in a better way, or how kill the process successfully without restarting the server?

  • How can i query for null values in entity framework?

    - by AZ
    I want to execute a query like this var result = from entry in table where entry.something == null select entry; and get an IS NULL generated. Edited: After the first two answers i feel the need to clarify that I'm using Entity Framework and not Linq to SQL. The object.Equals() method does not seem to work in EF. Edit no.2: The above query works as intended. It correctly generates IS NULL. My production code however was var value = null; var result = from entry in table where entry.something == value select entry; and the generated SQL was something = @p; @p = NULL. It seems that EF correctly translates the constant expression but if a variable is involved it treats it just like a normal comparison. Makes sense actually. I'll close this question

  • How to get entries from the second level query cache ?

My code is as following : def getCacheStats() { StatisticsImpl stats = sessionFactory.statistics for (regionName in stats.secondLevelCacheRegionNames) { log.debug stats.getSecondLevelCacheStatistics(regionName).entries } } However everything works fine as long as the region name is not org.hibernate.cache.StandardQueryCache (region used for Query Cache). In that case, an exception is thrown : java.lang.ClassCastException: org.hibernate.cache.QueryKey cannot be cast to org.hibernate.cache.CacheKey Having googling around, I didn't find any clues about how to display the list of entries of the cached query result sets associated with regions StandardQueryCache and UpdateTimestampsCache. Could you please help me find a solution for this?

  • STOP ERASING MY QUESTIONS! - VIEWING FIRST_ROWS BEFORE QUERY COMPLETES (RE-VISITED)

    - by Frank Developer
    OK, so say I have a table with 500K rows, then I ad-hoc query with unsupported indexing which requires a full table scan. I would like to immediately view the first rows returned while the full table scan continues. Then I want to scroll thru the next results. In the meantime, I would like to display the progress of the table scan, example: "SEARCHING.. FOUND 23 OF 500,000 ROWS SO FAR". If I scroll too far ahead, I want to display a message like: "REACHED LAST ROW IN LOOK-AHEAD BUFFER.. QUERY HAS NOT COMPLETED".. Can this be done? Maybe like: spawn/exec, declare scroll cursor, open, fetch, etc.?

  • Is it OK to open a DB4o file for query, insert, update multiple times?

    - by Khnle
    This is the way I am thinking of using DB4o. When I need to query, I would open the file, read and close: using (IObjectContainer db = Db4oFactory.OpenFile(Db4oFactory.NewConfiguration(), YapFileName)) { try { List<Pilot> pilots = db.Query<Pilot>().ToList<Pilot>(); } finally { try { db.Close(); } catch (Exception) { }; } } At some later time, when I need to insert, then using (IObjectContainer db = Db4oFactory.OpenFile(Db4oFactory.NewConfiguration(), YapFileName)) { try { Pilot pilot1 = new Pilot("Michael Schumacher", 100); db.Store(pilot1); } finally { try { db.Close(); } catch (Exception) { }; } } In this way, I thought I will keep the file more tidy by only having it open when needed, and have it closed most of the time. But I keep getting InvalidCastException Unable to cast object of type 'Db4objects.Db4o.Reflect.Generic.GenericObject' to type 'Pilot' What's the correct way to use DB4o?

  • SOAP - Why do I need to query for the values for an update?

    - by Phill Pafford
    I'm taking over a project and wanted to understand if this is common practice using SOAP. The process that is currently in place I have to query all the values before I do an update cause I need to pass back all the values that are not being updated. Does this sound right? Example Values: fname=phill lname=pafford address=123 main phone:222-555-1212 So if I just wanted to update the phone number I need to query for the record, get all the values and submit these values for an update. Example Update Values: fname=phill lname=pafford address=123 main phone:111-555-1212 I just want to know if this is common practice or should I change the functionality of this?

  • Which SQL query is faster? Filter on Join criteria or Where clause?

    - by Jon Erickson
    Compare these 2 queries. Is it faster to put the filter on the join criteria or in the were clause. I have always felt that it is faster on the join criteria because it reduces the result set at the soonest possible moment, but I don't know for sure. I'm going to build some tests to see, but I also wanted to get opinions on which would is clearer to read as well. Query 1 SELECT * FROM TableA a INNER JOIN TableXRef x ON a.ID = x.TableAID INNER JOIN TableB b ON x.TableBID = b.ID WHERE a.ID = 1 /* <-- Filter here? */ Query 2 SELECT * FROM TableA a INNER JOIN TableXRef x ON a.ID = x.TableAID AND a.ID = 1 /* <-- Or filter here? */ INNER JOIN TableB b ON x.TableBID = b.ID

  • Better performance to Query the DB or Cache small result sets?

    - by user169867
    Say I need to populate 4 or 5 dropdowns w/ items from a database. Each drop down will have < 15 items in it. These items almost never change. Now I could query the DB each time the page is accessed or I could grab the values from a custom class that would check to see if they already exist in ASP.Net's cache and only if they don't query the DB to update the cache. It's trivial for me to write but I'm unsure if the performace would be better or not. I think it would be (although not likely anything huge). What do you think?

SELECT distinct e.* from test_entities e JOIN test_metadata m1 on e.guid = m1.entity_guid JOIN test_metastrings ms1 on ms1.id = m1.name_id JOIN test_metastrings mv1 on mv1.id = m1.value_id JOIN test_objects_entity obj on e.guid = obj.guid JOIN test_metadata m2 on e.guid = m2.entity_guid JOIN test_metastrings ms2 on ms2.id = m2.name_id JOIN test_metastrings mv2 on mv2.id = m2.value_id JOIN test_metadata m3 on e.guid = m3.entity_guid JOIN test_metastrings ms3 on ms3.id = m3.name_id JOIN test_metastrings mv3 on mv3.id = m3.value_id JOIN test_metadata m4 on e.guid = m4.entity_guid JOIN test_metastrings ms4 on ms4.id = m4.name_id JOIN test_metastrings mv4 on mv4.id = m4.value_id JOIN test_metadata m5 on e.guid = m5.entity_guid JOIN test_metastrings ms5 on ms5.id = m5.name_id JOIN test_metastrings mv5 on mv5.id = m5.value_id JOIN test_metadata m6 on e.guid = m6.entity_guid JOIN test_metastrings ms6 on ms6.id = m6.name_id JOIN test_metastrings mv6 on mv6.id = m6.value_id where ms1.string='expire_date' and mv1.string <= 1272565800 and ms2.string='homecity' and mv2.string LIKE "%dasf%" and ms3.string='schoolname' and mv3.string LIKE "%asdf%" and ms4.string='award_amount' and mv4.string <= 123 and ms5.string='no_of_awards' and mv5.string <= 7 and ms6.string='avg_rating' and mv6.string <= 2 and e.type = 'object' and e.subtype = 5 and e.site_guid = 1 and (obj.title like '%asdf%') OR (obj.description like '%asdf%') and ( (e.access_id = -2 AND e.owner_guid IN ( SELECT guid_one FROM test_entity_relationships WHERE relationship='friend' AND guid_two=5 )) OR (e.access_id IN (2,1) OR (e.owner_guid = 5) OR ( e.access_id = 0 AND e.owner_guid = 5 ) ) and e.enabled='yes') and ( (m1.access_id = -2 AND m1.owner_guid IN ( SELECT guid_one FROM test_entity_relationships WHERE relationship='friend' AND guid_two=5 )) OR (m1.access_id IN (2,1) OR (m1.owner_guid = 5) OR ( m1.access_id = 0 AND m1.owner_guid = 5 ) ) and m1.enabled='yes') and ( (m2.access_id = -2 AND m2.owner_guid IN ( SELECT guid_one FROM test_entity_relationships WHERE relationship='friend' AND guid_two=5 )) OR (m2.access_id IN (2,1) OR (m2.owner_guid = 5) OR ( m2.access_id = 0 AND m2.owner_guid = 5 ) ) and m2.enabled='yes') and ( (m3.access_id = -2 AND m3.owner_guid IN ( SELECT guid_one FROM test_entity_relationships WHERE relationship='friend' AND guid_two=5 )) OR (m3.access_id IN (2,1) OR (m3.owner_guid = 5) OR ( m3.access_id = 0 AND m3.owner_guid = 5 ) ) and m3.enabled='yes') and ( (m4.access_id = -2 AND m4.owner_guid IN ( SELECT guid_one FROM test_entity_relationships WHERE relationship='friend' AND guid_two=5 )) OR (m4.access_id IN (2,1) OR (m4.owner_guid = 5) OR ( m4.access_id = 0 AND m4.owner_guid = 5 ) ) and m4.enabled='yes') and ( (m5.access_id = -2 AND m5.owner_guid IN ( SELECT guid_one FROM test_entity_relationships WHERE relationship='friend' AND guid_two=5 )) OR (m5.access_id IN (2,1) OR (m5.owner_guid = 5) OR ( m5.access_id = 0 AND m5.owner_guid = 5 ) ) and m5.enabled='yes') and ( (m6.access_id = -2 AND m6.owner_guid IN ( SELECT guid_one FROM test_entity_relationships WHERE relationship='friend' AND guid_two=5 )) OR (m6.access_id IN (2,1) OR (m6.owner_guid = 5) OR ( m6.access_id = 0 AND m6.owner_guid = 5 ) ) and m6.enabled='yes') order by obj.title limit 0, 10 this is the query that i am running.

  • How do I display a field's hidden characters in the result of a query in Oracle?

    - by Chris Williams
    I have two rows that have a varchar column that are different according to a Java .equals(). I can't easily change or debug the Java code that's running against this particular database but I do have access to do queries directly against the database using SQLDeveloper. The fields look the same to me (they are street addresses with two lines separated by some new line or carriage feed/new line combo). Is there a way to see all of the hidden characters as the result of a query?I'd like to avoid having to use the ascii() function with substr() on each of the rows to figure out which hidden character is different. I'd also accept some query that shows me which character is the first difference between the two fields.

  • How do I get query string value from script path?

    - by TruMan1
    I am adding my Javsacript file in pages with different query strings in the script path like this: Page1: <script type="text/javascript" src="file.js?abc=123"></script> Page2: <script type="text/javascript" src="file.js?abc=456"></script> Page3: <script type="text/javascript" src="file.js?abc=789"></script> In my Javascript file, how can I get the value of the "abc" param? I tried using window.location for this, but that does not work. In case it helps, below is a function I use to find the value of a query string param: function getQuerystring(key, defaultValue) { if (defaultValue == null) defaultValue = ""; key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); var regex = new RegExp("[\\?&]" + key + "=([^&#]*)"); var qs = regex.exec(window.location.href); if (qs == null) return defaultValue; else return qs[1]; }
