मेरे पास एक होमवर्क समस्या है मैं कुछ मदद के लिए इस्तेमाल कर सकता हूँ मुझे निम्नलिखित ईएनबीएफ़ स्टेटमेंट को बीएनएफ के लिए परिवर्तित करना होगा 

  & lt; S & gt; - & gt; & Lt; ए & gt; {बी & lt; ए & gt;} & lt; ए & gt; - & gt; एक [ख] & lt; a & gt;

यही वह है जो मैं अभी तक आया हूं; 

  & lt; S & gt; - & gt; & Lt; a & gt; | & Lt; a & gt; & lt; एस & gt; | ख & lt; a & gt; & Lt; a & gt; - & gt; & lt; एक & gt; | अब & lt; a & gt;

यह सही नहीं लगता है, मुख्यतः क्योंकि यह एक WAG है मेरी किताब (प्रोग्रामिंग भाषाओं की अवधारणाओं, सेबेस्टा) का उदाहरण मुझे बिल्कुल भी मदद नहीं कर रहा है। इसलिए अगर किसी के पास कोई अंतर्दृष्टि है, तो इसकी सराहना की जाएगी। धन्यवाद!

पहला व्याकरण छोटी गाड़ी लगता है, या कम से कम बेकार बेकार है लेकिन ईबीएनएफ को BNF में परिवर्तित करने के लिए एक यांत्रिक तरीके के लिए यहां एक नज़र डालें:

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'
