nhibernate - A correct way to load entities by Id list when Id is not mapped -

-

मेरे पास निम्न कोड है 

  string idName = builder.IdentifierName; विस्थापन विघटन = प्रतिबंध.डिसीकरण (); आईएलआईआईएसआईडीआईडी ​​= नया अर्रेइलाइट (इकाईइंफोस.लाइन); Foreach (इकाई entityInfos में var entityInfo) {आईडी.एड (entityInfo। आईडी); } विच्छेदन। जोड़ें (प्रतिबंध। इन (idName, आईडी)); criteria.Add (अलगाव); criteria.List ();

(मैं इसे नहीं लिखा है, यह NHibernate.Search से कोड सरलीकृत है)

idName का मान सही है ( "आईडी" )।

मेरे मैपिंग में मेरे पास आईडी संपत्ति के लिए आईडी नहीं है, यह केवल डीबी है: 

  & lt; आईडी कॉलम = "आईडी" प्रकार = "इंट" & gt; & Lt; जनरेटर वर्ग = "मूल" / & gt; & Lt; / आईडी & gt;

जब मैं कोड चलाने के लिए, यह एक अपवाद फेंकता है: 

  [QueryException: संपत्ति हल नहीं कर सका: ईद की: MyType] NHibernate.Persister.Entity .AbstractPropertyMapping.ToType (स्ट्रिंग प्रॉपर्टी) 326 NHibernate.Loader.Criteria.CriteriaQueryTranslator.GetTypeUsingProjection (ICriteria subcriteria, स्ट्रिंग प्रॉपर्टी) 416 NHibernate.Criterion.InExpression.AssertPropertyIsNotCollection (ICriteriaQuery criteriaQuery, ICriteria मापदंड) +41 NHibernate.Criterion.InExpression। ToSqlString (ICriteria मापदंड, ICriteriaQuery criteriaQuery, IDictionary`2 enabledFilters) +49 NHibernate.Criterion.Junction.ToSqlString (ICriteria मापदंड, ICriteriaQuery criteriaQuery, IDictionary`2 enabledFilters) 448 NHibernate.Loader.Criteria.CriteriaQueryTranslator.GetWhereCondition (IDictionary`2 enabledFilters ) +354 NHibernate.Loader.Criteria.CriteriaJoinWalker..ctor (IOuterJoinLoadable persister, CriteriaQueryTranslator अनुवादक, ISessionFactoryImplementor कारखाने, ICriteria मापदंड, स्ट्रिंग rootEntityName, IDictionary`2 enabledFilters) 516 NHibernate.Loader.Criteria.CriteriaLoader..ctor (IOuterJoinLoadable persister, ISessionFactoryImplementor कारखाने, CriteriaImpl rootCriteria, स्ट्रिंग rootEntityName, IDictionary`2 enabledFilters) 220 NHibernate.Impl.SessionImpl.List (CriteriaImpl मापदंड, IList परिणाम) 364 NHibernate.Impl.CriteriaImpl.List (IList परिणाम) 63 NHibernate.Impl.CriteriaImpl.List () +46

क्या करने के लिए सही तरीका क्या है एक प्रतिबंध और मानदंड तैयार करें ताकि मैं आईडी से खोज कर सकूं, भले ही इसे मैप नहीं किया गया हो?

कोशिश करें IdEq इसके बजाय इसे एक और संयोजन की आवश्यकता है। 

  अवधारणा ids रक्षित = प्रतिबंध.डिसीकरण (); EntityInfo। चुनें (x = & gt; x.Id) .toList () .पहला (आईडी = & gt; आईडी रिसेक्शन.एड (प्रतिबंध.आईडीईएक्स (आईडी))); disjunction.Add (idsRestriction);

ध्यान दें: यह (आईडी = 1 या आईडी = 2 या आईडी = 3 ...) के बजाय की तरह कुछ उत्पन्न करेगा (id IN ( 1, 2, 3) ।

सौ प्रतिशत यकीन है कि यह काम करता है, लेकिन यह चाहिए।

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
