Order of evaluation of conditionals in actionscript 3.0 (Flex) -

- 

  var बीटीएन: बटन; अगर (बीटीएन! = नल & amp; amp; बीटीएन.लैबेल! = '') {Mx.controls.Alert.show ("d"); }

उपरोक्त में अगर खंड, यह गारंटी है कि पहली शर्त (बीटीएन! = नल) दूसरी स्थिति से पहले मूल्यांकन की जाएगी?

हां - एक्शन स्क्रिप्ट और amp; amp; ऑपरेटर के लिए उपयुक्त शॉर्ट सर्किट करता है:

तो न केवल आपके द्वारा वर्णित क्रम में अभिव्यक्तियों का मूल्यांकन करेगा, यह दूसरी अभिव्यक्ति का मूल्यांकन करने में परेशान नहीं करेगा अगर पहले एक false (जो मूल्यांकन के क्रम के रूप में महत्वपूर्ण है)।

एक नोट के रूप में, एक्शन स्क्रिप्ट भी इसका समर्थन करता है।

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
