c# - LINQ newbie question for 2 dimensional set -

-

मेरे पास एक LINQ क्वेरी है जो पूर्णांक के साथ ID मान खींचती है: 

  var data = from एस में बेसडेटा का चयन करें नया s.rooid, s.Tid}; ? डेटा .ओएआरआरए () {& lt; & gt; f__AnonymousType0 & lt; int, int & gt; [14]} [0]: {Roid = 2384, Tid = 1} [1]: {Roid = 2384, Tid = 2} [2]: {Roid = 2384, Tid = 3} [3]: {Roid = 2385, Tid = 4} [4]: ​​{Roid = 2385, Tid = 5} [5]: {Roid = 2385, Tid = 6} [6 ]: {Roid = 2386, Tid = 1} [7]: {Roid = 2386, Tid = 3} [8]: {Roid = 2386, Tid = 6} [9]: {Roid = 2386, Tid = 7} [10]: {Roid = 2387, Tid = 1} [11]: {Roid = 2387, Tid = 2} [12]: {Roid = 2387, Tid = 4} [13]: {Roid = 2387, Tid = 9}   
 मैं क्या करना चाहूंगा, केवल एक रोध के लिए परिणाम सेट को क्वेरी और केवल टीड मानों को निकालने के लिए है।  
 इसलिए मैं रओड = 2387, जो 1, 2, 4, 9 लौटाएगा, जो मैं एक सरणी में कनवर्ट करना चाहता हूं।  
 क्या ऐसा कुछ संभव है?  
  // *** संपादित करें *** var आइटम = डेटा.ToArray ()। जहां (s = & gt; s.RepairOrderId == 2387); // मुझे करीब ले जाता है, लेकिन मैं अभी भी केवल TID का संपादन करना चाहता हूं *** संपादित करें ***    
 
 <पूर्व>  var tidsFromRoid = data.Where (x = & gt; x.Roid == 2387)। चुनें (x = & gt; x.Tid);   
 यह एक ऐसे बदलाव को वापस करेगा जिसमें केवल जोड़े शामिल हैं, जिनके  Roid == 2387 , और उसके बाद के बाद से, यह प्रत्येक तत्व को केवल इसके  Tid पर प्रोजेक्ट करता है ।  
 ध्यान दें कि यदि आप इसे एक सरणी के रूप में चाहते हैं, तो  कॉल करें। ToArray ()  के बाद:  
  var arrayOfTids = tidsFromRoid .ToArray ();   
 यदि आप इसे बहुत शुरुआत से करना चाहते हैं (क्योंकि आप कभी भी अन्य  roid  s के बारे में ध्यान नहीं देंगे) तो आप अपनी मूल क्वेरी बनाते हैं: < / P> 
  var सरणीऑफ़टीड्स = बेसडेटा.वहाँ (x = & gt; x.Roid == 2387)। चयन करें (x = & gt; x.Tid) .ओएरे ();

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

c# - Using Vici cool Storage with monodroid -

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment. Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
