php - Mysql selection from more than one table -

- 

  का चयन करें * कुत्ते से कहाँ (चुनें कॉल करने वाला FROM jos_users WHERE `user_id` = '"। $ Cid। "' ) = सबोड   
  $ cid   jos_users  में पहचानकर्ता है, जो हमें बताता है कि हम किस उपयोगकर्ता को डेटा ला रहे हैं  
 मैं जो डेटा प्राप्त करना चाहता हूं वह "कुत्ते" के भीतर है, और कॉलुसर दोनों के बीच पहचानकर्ता है (जो हमें बताता है कि कौन कौन है कुत्ते हैं)  
 मुझे केवल कुत्तों को कॉल करने में सक्षम होना चाहिए प्रश्न में उपयोगकर्ता के लिए प्रासंगिक, लेकिन यह भी एक क्वेरी में किया जाना चाहिए। क्या कोई मदद कर सकता है? बहुत सराहना की है।   
 
 
 आपको जुड़ने का उपयोग करने की आवश्यकता है। 
 इस ट्यूटोरियल पढ़ें:  < P> आपकी क्वेरी कुछ इस तरह दिखनी चाहिए:  
  $ cid = mysql_real_escape_string ($ _ GET ['cid']); $ Query = "SELECT d। * कुत्ते डी इनर से Jos_users जू पर (d.user_id = ju.id) जहां से ju.id = '$ cid'";

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...

javascript - What is an alternative to using getElementByClass for hiding multiple elements? -

-
I have a page with some links that I would like to be able to toggle with two buttons. It works with a link using getElementById, but I need to toggle some of those groups. I started with it, but it failed to work. I've heard that GetElementByClass has worked with everything but IE, but I'm using Opera 11.5 and it still does not work. I've searched a bit, but I'm new to some JavaScript and most of the explanation is not understood. Does anyone help me with a simple option, or can I help me fix the problem I've made? This is a test page I was using. & lt; Head & gt; & Lt; Script type = "text / javascript" & gt; Function hideNames () {document.getElementByClass ("WebName"). Style.display = "none"; } Function ShowName () {document.getElementByClass ("WebName"). Style.display = "inline"; } & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; P class = "web...

c# - GetType() == type perfomance question -

-
I am making an XNA game and I am calling the following updates 2 to 20 times the code. I tried googling and it seems that it is half slow, so I thought I was asking what kind of fast way to compare the type? code: Public modifier for this [type type] {for (int i = 0; i & lt; this.Qount; i ++) {if ( It [I.] Type GETType () ==) {Please return this [ii]; }} New NotImplementedException Throw ("Fix It"); } Set {for (int i = 0; i & lt; this.Qount; i ++) {if (this [i]. Type GetType () ==) {this [i] = value; }} If (System. Diagnostics.Debugor.ISAcredited) system. Diagnostics. Debugger. Break (); }} This code is in the modifier collection section which comes from a list. The modifier is a part of the particle engine. In addition, my game is not in a situation where I can actually do this test, so I can not test it, but should it work right? I read something about runtime typhanies, which is fast, should I use it? Thanks a lot! Edit: What I'm aiming to do ...
