python - seek () function? - Stack Overflow The seek position is a byte index into the contents of the file similar to an array index Its also interesting that if we open file in append mode 'a', we cannot seek to file's beginning
c++ - fstream seekg (), seekp (), and write () - Stack Overflow 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
What is the difference between Lookup, Scan and Seek? Every individual seek, scan, lookup, or update on the specified index by one query execution is counted as a use of that index and increments the corresponding counter in this view
Stream. Seek (0, SeekOrigin. Begin) or Position = 0 If you are working with files (eg: with the FileStream class) it seems Seek (0, SeekOrigin Begin) is able to keep internal buffer (when possible) while Position=0 will always discard it
c# - Stream wrapper to make Stream seekable? - Stack Overflow Here's a wrapper to make any Stream seekable for read operations It works by caching reads from the underlying stream, up to the number of bytes specified in the constructor This will come in handy when memory constraints prohibit Marc Gravell's solution Supported seek operations: seeking forward using SeekOrigin Current and SeekOrigin Begin works for arbitrary offsets seeking backwards
How to improve performance on a clustered index seek 9 A clustered index range seek that returns 138 rows is not your problem Technically you can improve the seek performance by making the clustered index narrower: evict all varlenght into a separate allocation unit by setting 'large value types out of row ' to 1 and recreating the table from scratch) enable page compression (SQL 2008 EE only)
