Could a seek destroy my previously written data if it's still buffered somewhere? The seek call uses some strategy internally and I can't follow that path. No idea what it's doing internally. Do I need to call Flush () explicitly before any Seek ()? Or does the FileStream know which data needs to go where?
Please excuse my confusion here but I have read the documentation regarding the seek() function in Python (after having to use it). Although it helped me I am still a bit confused on the actual mea...
What this means is that when you use a std::basic_fstream, which by default uses a std::basic_filebuf, the single file position is moved by both seekp() and seekg(); unless you use a separate variable to store one of the positions so you can then seek back to it, you cannot keep track of put and get positions independently.

In a SQL Server Execution plan what is the difference between an Index Scan and an Index Seek I'm on SQL Server 2005.
Adding additional key columns follows the same pattern. Now, if you think about it, SQL Server should be able to use an INDEX SEEK operator to find the desired record, and indeed it does so for most of my tables. However, I have found one table where, no matter what I have tried, SQL Server insists on doing an INDEX SCAN, which is of course much slower in a big table (which this table is). I ...
