CONV() 用于不同进制数之间的转换
mysql> SELECT CONV(‘a‘,16,2), # 将16进制的a转换为2进制 -> CONV(15,10,2), # 将10进制的15转换为2进制 -> CONV(15,10,8), # 将10进制的15转换为8进制 -> CONV(15,10,16); # 将10进制的15转换为16进制 +----------------+---------------+---------------+----------------+ | CONV(‘a‘,16,2) | CONV(15,10,2) | CONV(15,10,8) | CONV(15,10,16) | +----------------+---------------+---------------+----------------+ | 1010 | 1111 | 17 | F | +----------------+---------------+---------------+----------------+
