replication problem

[赵琦]

hi all:
    I have three mysql database,tow run as master and the other one runs as
slave.
Some tables in the database have an autoincreament field named as 'rowid'.
These
tables have 1000000 records on master, but some of these tables on the
slave only have thousands
of record. The tables on the slave are  not the same as those on master.
    When i use 'show slave status', i find that Last_Errno equals to 0.
How to solve this problem.
