About the composition of Linux command -

मान लें:

  1. फ़ाइल का पथ ~ / f
    2. < Li> "जो" च "~ / f" से पता चलता है,

फिर,

जो f | बिल्ली दिखाता है ~ / f । तो cat यहां ~ / f के उद्धरण पर लागू होता है, जो कि cat ~ / f के साथ अलग है।

मेरा प्रश्न यह है कि मैं cat ~ / f के परिणाम को प्राप्त करने के लिए जो और cat से बना एक कमांड का उपयोग कर सकता हूं? जब मुझे जो का परिणाम अग्रिम में नहीं पता है, तो इस संरचना का उपयोग बहुत सुविधाजनक हो सकता है वर्तमान में, अगर मुझे के परिणाम का पता नहीं है तो अग्रिम में, मुझे जो पहले एफ लागू करना है, और परिणाम को कॉपी करने के लिए कॉपी करें कम ।

एक संबंधित प्रश्न यह है कि मैं के परिणाम को एक चर में कैसे निर्दिष्ट करूं?

बहुत बहुत धन्यवाद!

बिल्ली "जो कि एफ <"

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'
