Without file system caching, Q1 performs similarly on XML and CLOB columns, with a slight disadvantage (10%) for the CLOB column which is not buffered in the buffer pool.
在没有文件系统缓存的情况下，XML和clob列的Q1执行效果类似，不在缓冲池进行缓冲的clob列略微落后(10%)。
This is important in Python programs because file input and output are, by default, buffered; data isn't written as soon as you call a print statement but is instead written in chunks.
在Python程序中这很重要，因为在默认情况下，文件输入和输出是缓冲的；在调用print语句时，数据实际未被写入；相反，数据是成批写入的。
You can also open a buffered binary file by using the form open (fileName, 'b').
您也可以使用open (fileName，'b ')打开一个缓冲了的二进制文件。
The buffered data that is written to the file includes the content of the child, named file, of the global environment section of the logical tree.
要写入文件的缓冲区数据包括逻辑树的globalenvironment部分的子元素的内容、namedFile。
Doing so returns a buffered text file; read and readline return strings. (Remember that all strings in Python 3 are unicode.)
这么做会返回一个缓冲了的文本文件；read和readline会返回字符串(请注意，Python3内的所有字符串都是unicode)。
Without file system caching, this overhead is mitigated by the fact that XML columns are buffered in the DB2 buffer pool and CLOB columns are not.
在没有文件系统缓存的情况下，xml列在db2缓冲池进行缓冲而clob列则不是，从而可降低开销。
Clears buffers for this stream and causes any buffered data to be written to the file.
清除这个资料流的缓冲区，让所有缓冲资料全部写入档案。
It is possible to lose output data that is buffered if you do not explicitly close a file.
如果你不显式地关闭文件，那么你可能丢失输出缓冲区的数据。
Clears buffers for this stream and causes any buffered data to be written to the file, and also clears all intermediate file buffers.
清除此流的缓冲区，将所有缓冲的数据都写入到文件中，另外也清除所有中间文件缓冲区。
Clears buffers for this stream and causes any buffered data to be written to the file, and also clears all intermediate file buffers.
清除此流的缓冲区，将所有缓冲的数据都写入到文件中，另外也清除所有中间文件缓冲区。
