sql server - How can I set a BIT variable based on a value variable? -

-

मेरे पास है: 

  DECLARE @Authenticated BIT यदि @@ ROWCOUNT & gt; 0 शुरू होता है का चयन करें @अधिकृत = 1 अंत ELSE शुरू करें SELECT @Authenticated = 0 end   
 क्या कोई ऐसा तरीका है जो मैं BEGINEND के बिना कर सकता हूं और यह भी एक बिट डेटाटाइप को एक अच्छा तरीका सेट कर रहा है झूठी सच्चाई का प्रतिनिधित्व करते हैं?   
 
 
 आप इसे और अधिक संक्षिप्त रूप से करने के लिए  मामला  का उपयोग कर सकते हैं , जैसे:  
  SET @ authenticated = (SELECT CASE WHEN @@ ROWCOUNT & gt; 0 THEN 1 ELSE 0 END)   
 इसके अलावा,  बीआईटी  सही / गलत का प्रतिनिधित्व करने के लिए एक अच्छा विकल्प होगा, क्योंकि वह बहुत ज्यादा बिट्स की तरह काम करता है - या तो 0 या 1।

I can declare the following with no problem: var UIAuto: IUIAutomation; Element: IUIAutomationElement; But the methods of IUIAutomationElement are missing. For example, there is nothing in the interface declaring this method: IUIAutomationElement.TryGetCurrentPattern () ... which msdn.microsoft According to .com, there is an interface method which is returning to at least NET 3.0. Where do...
