I have a hive table with the below schema.



Table A:



`li_number string



id1 string



id2 string



id3 string



id4 string



id5 string



id6 string



id7 string



id8 string



id9 string



id10 string



created_date date`



Table B:



`id string



created_date date`



From table A, i need to take unique id's from id1 to id10 and load them in table B id column. Also i need to load created date column with the current date of loading



I have achieved the same using an shell script and load statement of hive. but i need this to be done using only hive. Please help me.

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
