  • LINQ Multiple LIKE based on List

    - by Bathan
    I have a list of keywords in an ArrayList and I wanted to be able to build a query to find records in a table based on this keywords. Since the list of keywords is dynamic I cannot build a fixed query here. if I do something like this: foreach (string kw in keywords) { query = query.Where(p => p.Name.StartsWith(kw)); } The "StartsWith" is required here because I need to search those records that actually start with the provided keyword. In T-SQL it Would be something like this Select * from Table where Name like 'keyword1%' or Name like 'keyword2%' or Name like 'keyword3%' or ... But I need to be able to do this in LINQ...Is this possible?

  • Twitter oauth php problems

    - by Patrick Gates
    I'm writing some backend script for a twitter app and heres how it's going On the app you click a button that sends you to login.php on my server which logs into my database connects to twitter with my consumer key and secret: $to = new TwitterOAuth($consumer_key, $consumer_secret); $tok = $to->getRequestToken(); $request_link = $to->getAuthorizeURL($tok); and then writes the token and secret to the database, sets a session equal to the id in the database of the token and secret and then redirects to the "$request_link" You then go through the process of logging in and such on twitter and it redirects you to callback.php on my server Callback.php consists of logging into the database again, getting the new token and secret, and then writing the new token and secret to the database and then prompts you to go back to the app Then on the app, all I'm trying to do is access the basic credentials$to->get('account/verify_credentials') and it keeps coming back "could not authenticate you" What am I doing wrong?? Thank you for all the help :)

  • Problem detaching entire object graph in GAE-J with JDO

    - by tempy
    I am trying to load the full object graph for User, which contains a collection of decks, which then contains a collection of cards, as such: User: @PersistenceCapable(detachable = "true") @Inheritance(strategy = InheritanceStrategy.SUBCLASS_TABLE) @FetchGroup(name = "decks", members = { @Persistent(name = "_Decks") }) public abstract class User { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) protected Key _ID; @Persistent protected String _UniqueIdentifier; @Persistent(mappedBy = "_Owner") @Element(dependent = "true") protected Set<Deck> _Decks; protected User() { } } Each Deck has a collection of Cards, as such: @PersistenceCapable(detachable = "true") @FetchGroup(name = "cards", members = { @Persistent(name = "_Cards") }) public class Deck { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key _ID; @Persistent String _Name; @Persistent(mappedBy = "_Parent") @Element(dependent = "true") private Set<Card> _Cards = new HashSet<Card>(); @Persistent private Set<String> _Tags = new HashSet<String>(); @Persistent private User _Owner; } And finally, each card: @PersistenceCapable public class Card { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key _ID; @Persistent private Text _Question; @Persistent private Text _Answer; @Persistent private Deck _Parent; } I am trying to retrieve and then detach the entire object graph. I can see in the debugger that it loads fine, but then when I get to detaching, I can't make anything beyond the User object load. (No Decks, no Cards). At first I tried without a transaction to simply "touch" all the fields on the attached object before detaching, but that didn't help. Then I tried adding everything to the default fetch group, but that just generated warnings about GAE not supporting joins. I tried setting the fetch plan's max fetch depth to -1, but that didn't do it. Finally, I tried using FetchGroups as you can see above, and then retrieving with the following code: PersistenceManager pm = _pmf.getPersistenceManager(); pm.setDetachAllOnCommit(true); pm.getFetchPlan().setGroup("decks"); pm.getFetchPlan().setGroup("cards"); Transaction tx = pm.currentTransaction(); Query query = null; try { tx.begin(); query = pm.newQuery(GoogleAccountsUser.class); //Subclass of User query.setFilter("_UniqueIdentifier == TheUser"); query.declareParameters("String TheUser"); List<User> results = (List<User>)query.execute(ID); //ID = Supplied parameter //TODO: Test for more than one result and throw if(results.size() == 0) { tx.commit(); return null; } else { User usr = (User)results.get(0); //usr = pm.detachCopy(usr); tx.commit(); return usr; } } finally { query.closeAll(); if (tx.isActive()) { tx.rollback(); } pm.close(); } This also doesn't work, and I'm running out of ideas...

  • Using Javascript to detect the bottom of the window and ignoring all events when a request is loading

    - by Aaron Reba
    I have an anonymous function to detect the user has scrolled to the bottom of the window. Inside of the anonymous function, I have a call to a database that takes a while to complete. var allowing_more = 1; $(window).scroll(function() { if (allowing_more == 1){ if ($(window).scrollTop() + $(window).height() == $(document).height()) { allowing_more = 0; //query allowing_more = 1; } } }); In this time, if the user scrolls to the bottom of the window again, it seems a queue is made holding the occurences the user scrolled to the bottom of the window while the query was loading. Upon completing of the query, these occurences are then executed. I have a boolean statement to detect if the anonymous function is accepting more query requests but this seems to be ignored. Is there some sort of way to ignore an anonymous function temporarily and re-enable it?

  • Many users, many cpus, no delays. Good for cloud?

    - by Eric
    I wish to set up a CPU-intensive time-important query service for users on the internet. A usage scenario is described below. Is cloud computing the right way to go for such an implementation? If so, what cloud vendor(s) cater to this type of application? I ask specifically, in terms of: 1) pricing 2) latency resulting from: - slow CPUs, instance creations, JIT compiles, etc.. - internal management and communication of processes inside the cloud (e.g. a queuing process and a calculation process) - communication between cloud and end user 3) ease of deployment A usage scenario I am expecting is: - A typical user sends a query (XML of size around 1K) once every 30 seconds on average. - Each query requires a numerical computation of average time 0.2 sec and max time 1 sec on a 1 GHz Pentium. The computation requires no data other than the query itself and is performed by the same piece of code each time. - The delay a user experiences between sending a query and receiving a response should be on average no more than 2 seconds and in general no more than 5 seconds. - A background save to a DB of the response should occur (not time critical) - There can be up to 30000 simultaneous users - i.e., on average 1000 queries a second, each requiring an average 0.2 sec calculation, so that would necessitate around 200 CPUs. Currently I'm look at GAE Java (for quicker deployment and less IT hassle) and EC2 (Speed and price optimization) as options. Where can I learn more about the right way to set ups such a system? past threads, different blogs, books, etc.. BTW, if my terminology is wrong or confusing, please let me know. I'd greatly appreciate any help.

  • MySQL Join/Comparison on a DATETIME column (<5.6.4 and > 5.6.4)

    - by Simon
    Suppose i have two tables like so: Events ID (PK int autoInc), Time (datetime), Caption (varchar) Position ID (PK int autoinc), Time (datetime), Easting (float), Northing (float) Is it safe to, for example, list all the events and their position if I am using the Time field as my joining criteria? I.e.: SELECT E.*,P.* FROM Events E JOIN Position P ON E.Time = P.Time OR, even just simply comparing a datetime value (taking into consideration that the parameterized value may contain the fractional seconds part - which MySQL has always accepted) e.g. SELECT E.* FROM Events E WHERE E.Time = @Time I understand MySQL (before version 5.6.4) only stores datetime fields WITHOUT milliseconds. So I would assume this query would function OK. However as of version 5.6.4, I have read MySQL can now store milliseconds with the datetime field. Assuming datetime values are inserted using functions such as NOW(), the milliseconds are truncated (<5.6.4) which I would assume allow the above query to work. However, with version 5.6.4 and later, this could potentially NOT work. I am, and only ever will be interested in second accuracy. If anyone could answer the following questions would be greatly appreciated: In General, how does MySQL compare datetime fields against one another (consider the above query). Is the above query fine, and does it make use of indexes on the time fields? (MySQL < 5.6.4) Is there any way to exclude milliseconds? I.e. when inserting and in conditional joins/selects etc? (MySQL 5.6.4) Will the join query above work? (MySQL 5.6.4) EDIT I know i can cast the datetimes, thanks for those that answered, but i'm trying to tackle the root of the problem here (the fact that the storage type/definition has been changed) and i DO NOT want to use functions in my queries. This negates all my work of optimizing queries applying indexes etc, not to mention having to rewrite all my queries. EDIT2 Can anyone out there suggest a reason NOT to join on a DATETIME field using second accuracy?

  • laravel multiple where clauses within a loop

    Pretty much I want the query to select all records of users that are 25 years old AND are either between 150-170cm OR 190-200cm. I have this query written down below. However the problem is it keeps getting 25 year olds OR people who are 190-200cm instead of 25 year olds that are 150-170 OR 25 year olds that 190-200cm tall. How can I fix this? thanks $heightarray=array(array(150,170),array(190,200)); $user->where('age',25); for($i=0;$i<count($heightarray);i++){ if($i==0){ $user->whereBetween('height',$heightarray[$i]) }else{ $user->orWhereBetween('height',$heightarray[$i]) } } $user->get(); Edit: I tried advanced wheres (http://laravel.com/docs/queries#advanced-wheres) and it doesn't work for me as I cannot pass the $heightarray parameter into the closure. from laravel documentation DB::table('users') ->where('name', '=', 'John') ->orWhere(function($query) { $query->where('votes', '>', 100) ->where('title', '<>', 'Admin'); }) ->get();

  • How to create and Expression tree to do the same as "StartsWith"

    - by Jonathan
    Hi to all. Currently, I have this method to compare two numbers Private Function ETForGreaterThan(ByVal query As IQueryable(Of T), ByVal propertyValue As Object, ByVal propertyInfo As PropertyInfo) As IQueryable(Of T) Dim e As ParameterExpression = Expression.Parameter(GetType(T), "e") Dim m As MemberExpression = Expression.MakeMemberAccess(e, propertyInfo) Dim c As ConstantExpression = Expression.Constant(propertyValue, propertyValue.GetType()) Dim b As BinaryExpression = Expression.GreaterThan(m, c) Dim lambda As Expression(Of Func(Of T, Boolean)) = Expression.Lambda(Of Func(Of T, Boolean))(b, e) Return query.Where(lambda) End Function It works fine and is consumed in this way query = ETForGreaterThan(query, Value, propertyInfo) As you can see, I give it an IQueryable collection and it add a where clause to it, base on a property and a value. Y can construct Lessthan, LessOrEqualThan etc equivalents as Expression has this operators predefined. ¿How can I transform this code to do the same with strings? Expression don't give me a predefined operator like "contains" or "startwith" and I'm really noob with Expression trees. Thanks, and please Post your answer in C#/VB. Choose the one that make you feel more confortable.

  • PHP syntax for postgresql Mixed-case table names

    - by yam
    I have a code below: <?php require "institution.php" /* in this portion, query for database connection is executed, and */ $institution= $_POST['institutionname']; $sCampID = 'SELECT ins_id FROM institution where ins_name= '$institution' '; $qcampID = pg_query($sCampID) or die("Error in query: $query." . pg_last_error($connection)); /* this portion outputs the ins_id */ ?> My database before has no mixed-case table names, that's why when I run this query, it shows no error at all. But because I've changed my database for some reasons, and it contains now mixed-case table names, i have to change the code above into this one: $sCampID = 'SELECT ins_id FROM "Institution" where ins_name= '$institution' '; where the Institution has to be double quoted. The query returned parse error. When i removed this portion: where ins_name= '$institution', no error occured. My question is how do I solve this problem where the table name which contains a mixed-case letter and a value stored in a variable ($institution in this case) will be combined in a single select statement? Your answers and suggestions will be very much appreciated.

  • How to check if a child-object is populated

    - by TheQ
    How can i check if a child-object of a linq-object is populated or not? Example code below. My model have two methods, one joins data, and the other does not: public static Member GetMemberWithPhoto(Guid memberId) { using (DataContext db = new DataContext()) { DataLoadOptions dataLoadOptions = new DataLoadOptions(); dataLoadOptions.LoadWith<Member>(x => x.UserPhoto); db.LoadOptions = dataLoadOptions; var query = from x in db.Members where x.MemberId == memberId select x; return query.FirstOrDefault(); } } public static Member GetMember(Guid memberId) { using (DataContext db = new DataContext()) { var query = from x in db.Members where x.MemberId == memberId select x; return query.FirstOrDefault(); } } Then my control have the following code: Member member1 = Member.GetMemberWithPhoto(memberId); Member member2 = Member.GetMember(memberId); Debug.WriteLine(member1.UserPhoto.ToString()); Debug.WriteLine(member2.UserPhoto.ToString()); The last line will generate a "Cannot access a disposed object" exception. I know that i can get rid of that exception just by not disposing the datacontext, but then the last line will generate a new query to the database, and i don't want that. What i would like is something like: Debug.WriteLine((member1.UserPhoto.IsPopulated()) ? member1.UserPhoto.ToString() : "none"); Debug.WriteLine((member2.UserPhoto.IsPopulated()) ? member2.UserPhoto.ToString() : "none"); Is it possible?

  • Snapshot on, still deadlocks, ROWLOCK

    - by Patto
    I turned snapshot isolation on in my database using the following code ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON and got rid off lots of deadlocks. But my database still produces deadlocks, when I need to run a script every hour to clean up 100,000+ rows. Is there a way I can avoid deadlocks in my cleanup script, do I need to set ROWLOCK specifically in that query? Is there a way to increase the number of row level locks that a database uses? How are locks promoted? From row level to page level to table level? My delete script is rather simple: delete statvalue from statValue, (select dateadd(minute,-60, getdate()) as cutoff_date) cd where temporaryStat = 1 and entrydate < cutoff_date Right now I am looking for quick solution, but a long term solution would be even nicer. Thanks a lot, Patrikc

  • .Net SQL Parameter for String List Problem

    - by JK
    I am writing a C# program in which I send a query to SQL Server to be processed and a dataset returns. I am using parameters to pass information to the query before it is sent to SQL server. This works fine except in the situation below. The query looks like this: reportQuery = " Select * From tableName Where Account_Number in (@AccountNum); and Account_Date = @AccountDate "; The AccountDate parameter works find but not the AccountNum parameter. I need the final query to execute like this: Select * From tableName Where Account_Number in ('AX3456','YZYL123','ZZZ123'); and Account_Date = '1-Jan-2010' The problem is that I have these account numbers (actually text) in a C# string list. To feed it to the parameter, I have been declaring the parameter as a string. I turn the list into one string and feed it to the parameter. I think the problem is that I am feeding the paramater this: "'AX3456','YZYL123','ZZZ123'" when it wants this 'AX3456','YZYL123','ZZZ123' How do I get the string list into the query using a parameter and have it execute as shown above? This is how I am declaring and assigning the parameter. SqlParameter AccountNumsParam = new SqlParameter(); AccountNumsParam.ParameterName = "@AccountNums"; AccountNumsParam.SqlDbType = SqlDbType.NVarChar; AccountNumsParam.Value = AccountNumsString; FYI, AccountNumString == "'AX3456','YZYL123','ZZZ123'"

  • Anyway to get a value similar to @@ROWCOUNT when TOP is used?

    - by cfeduke
    If I have a SQL statement such as: SELECT TOP 5 * FROM Person WHERE Name LIKE 'Sm%' ORDER BY ID DESC PRINT @@ROWCOUNT -- shows '5' Is there anyway to get a value like @@ROWCOUNT that is the actual count of all of the rows that match the query without re-issuing the query again sans the TOP 5? The actual problem is a much more complex and intensive query that performs beautifully since we can use TOP n or SET ROWCOUNT n but then we cannot get a total count which is required to display paging information in the UI correctly. Presently we have to re-issue the query with a @Count = COUNT(ID) instead of *.

  • SQL change "like" to "contains"

    - by Paul
    products table (mySQL) record_id categories (comma-delimited list) --------- -------------------------------- 1 960|1,957|1,958|1 I have the following dynamic query (simplified for the purposes of this question). The query is passed specified categories, each in the format xxxx|yyyy, and I need to return products having the passed category in its comma-delimited list of categories. The current query looks like: select p.* from products p where (p.categories like '%27|0%' or p.categories like '%972|1%' or p.categories like '%969|1%') But, the LIKE clause sometimes permits anomalies. I would like to write the query more like: select p.* from products p where (p.categories contains '27|0' or p.categories contains'972|1' or p.categories contains '969|1') How would I do this?
