Oracle field typeHttp://www.cnblogs.com/lihan/archive/2010/01/06/1640547.html Field type Describe Field length and its default value CHAR (size) String data used to hold the fixed length (size) byte. The length of each line is fixed (the insufficient part is blank), the maximum is 2000 bytes per line, and the default value is 1 bytes per line. Consider the character set to be single-byte or multibyte before setting the length (size).
