Today encountered an exception, the code is as follows:set.seed(12345)require(ggplot2)AData i p # all rightp p # Error: Aesthetics must either be length one, or the same length as the dataProblems:AData下面的代码就ok:example myplot geom_text(aes(label=rownames(example)), size=4.4, hjust=0.5, vjust=-1)根据异常信息，应该是说Glabel与AData的长度不同，但具体什么原因不了解。stackover上面的解释是：对于0.9.0版本的ggplot2有这个问题，0.9.1版本中已经解决。（http://stackoverflow.

Char (n) is a fixed-length format. The field in the format of char (n) occupies a fixed width of n characters. If the actual length of the stored data exceeds n, the excess data is truncated, if the length is less than n, it will be filled with null characters. Varchar (n) is a variable-length format. Fields in this f

Why can Oracle varchar2 (4000) connect with the JDBC thin driver only store 666 Chinese characters? Who says they can only store 666 Chinese characters? Varchar2 is a maximum of 4000 bytes, So it depends on your Oracle character set. If the character set is 16-bit encoded, zhs16gbk, then each character is 16-bit, 2-byte, so it can accommodate 2000 characters.If it is a 32-bit character set, only 1000 characters can be stored. Select length ('ours '),
