ebay interview questions
A reader
went through an interview at eBay and shared the
questions asked.
1.Let’s say you have 100,000 records and you want to
delete 95,000 at a time and keep only 5 thousand. But in
local memory you don’t have enough space for 95,000
records. What do you do in this case? 2.How do you
delete without any problem with time and performance?
I need data on eBay customers in Chicago who can did bid
on certain item? I dont have access to eBay database
directly. How I get the information?
3.With
DTS packaging I can store tables in Excel and convert
them back to SQL. But once I copied tables to Excel I
want to modify some info. How you do that without
editing the Excel file?
4.What is cursor and where do you use them? |
