关于Oracle位图索引内部浅论(4)

关于阅读这部分信息参考
What is 6D DB B6?
 6D = 1101101
 DB = 11011011
 B6 = 10110110
 Read from least significant bit (right to left) and left pad with zeros if not eight bits.
 The resulting map is
 10110110 11011011 01101101
 An important point is to read the bitmap from left to right in hexadecimal in two-byte
 chunks. Read each of those chunks in binary right (least significant bit) to left. If there
 are not eight bits, then these would have been in effect, leading zeros, and are treated
 as such. The underlined zero above demonstrates this.
