... Order by if (instr (name, 'A')> 0, 0) descDo you have a full sentence example? I cannot understand such a sentence!
This half sentence is understandable.That is to say, convert the string contain
or 2 of the SQL Ike how to sort data by like?
Name like "%a%" OR Time "%b%"
How to finish the result of like a in row B?
------Solution--------------------... order by if (InStr (Name, ' A ') >0,1,0) desc------Solution--------------------This half is enough to understand.That is, by looking for a string containing ' a ' to turn 0, 1, and then sort by 01, containing 1, not containing 0The final sort is Order by if (InStr (Name, ' A ') >0,1,0) desc--
solution will not be guaranteed.
Solution 2: wired
The cable solution can only deploy single-mode optical fiber cables at a distance of 12 kilometers, which is more time-consuming and costly. You can say you don't have to think about it.
Solution 3: Internet + VPN
The Internet can be said to be a public wide area network, and many telecom operators have established a four-way and eight-way long-distance network, which makes it possible for our compan

Rd (route-distinguisher) is used to identify different VPN instances on the PE device. Its main function is to achieve address multiplexing between VPN instances. It and the IP address constitute a 12byte vpnv4 address space, rd and the route are carried together in the bgp update message and published to the peer end. On the one hand, we
