Mysql OCP 79题


You have a server that has very limited memory but has a very large table.
You will use mysqldump to backup this table.
Which option will ensure mysqldump will process a row at a time instead of buffering a set of rows?
A. —tab
B. —single-transaction
C. —quick
D. —skip-buffer
Answer: C
如果由于大型结果集的内存不足而出现问题,请使用 — quick 选项。这迫使 mysql 每次从服务器检索一行结果,而不是检索整个结果集并在显示之前在内存中缓冲它。
