select TABLE_NAME from tables where TABLE_SCHEMA='dbname' and TABLE_NAME not in (从库执行出的结果);
+------------------------------+
| TABLE_NAME |
+-------------------------------+
| gwk_merchant |
| high_category |
| high_comm_product |
| import_cpa_confirm_666 |
| liujuntest |
| test_1501 |
| test_product_1501 |
+-------------------------------+
7 rows in set (0.01 sec)
这样查出来是主库上有而从库上没有的表，，需要在从库上创建，
主库执行导出数据：mysqldump -pxxx --default-character-set=utf8 --quick --single-transaction --master-data=2 --routines --triggers --events dbname gwk_merchant high_category high_comm_product import_cpa_confirm_666 liujuntest test_1501 test_product_1501 | gzip --fast > /data2/5.sql.gz
导出来都 放到从库上，
[root@host8~]# zcat /data/5.sql.gz | mysql -pxxx --socket=/data/mysql/mysql.sock dbname
SELECT COUNT(*) TABLES, table_schema FROM information_schema.TABLES WHERE table_schema = 'dbname' GROUP BY table_schema;
在主库从库上查看表是不是一样，从库上表多的话，查找出来要drop掉
查出来主库上的所有表：
mysql -pXXX -uroot
use information_schema;
set group_concat_max_len=5000;
select GROUP_CONCAT(concat("'",TABLE_NAME,"'")) from tables where TABLE_SCHEMA='dbname'\G
在从库上过滤不在主库的所有表：
mysql -pxxx -uroot
use information_schema;
select GROUP_CONCAT(concat("'",TABLE_NAME,"'")) from tables where TABLE_SCHEMA='dbname' and TABLE_NAME not in (主库执行出的结果);
| GROUP_CONCAT(concat("'",TABLE_NAME,"'")) 'board_stat_1411_bak','board_stat_1501','board_stat_1502','board_stat_1503','board_stat_1504','board_stat_1505','board_stat_1506','board_stat_1507','board_stat_1508','board_stat_1509','board_stat_1510','board_stat_1511','board_stat_1512','cps_effect_confirm_log_1408_6712_invalid_bak','cps_effect_confirm_log_1411_4018','cps_effect_confirm_log_1506','cps_effect_confirm_log_1507','cps_effect_confirm_log_1508','cps_effect_confirm_log_1509','cps_effect_confirm_log_1510','cps_effect_confirm_log_1511','cps_effect_confirm_log_1512','cps_effect_confirm_log_rollback_15','cps_order_status_log_1502','cps_order_status_log_1503','cps_order_status_log_1504','cps_order_status_log_1505','cps_order_status_log_1506','cps_order_status_log_1507','cps_order_status_log_1508','cps_order_status_log_1509','cps_order_status_log_1510','cps_order_status_log_1511','cps_order_status_log_1512','datasum_1506','datasum_1507','datasum_1508','datasum_1509','datasum_1510','datasum_1511','datasum_1512','datasum_part20150513_bak','datasum_part_huatong_like','flow_stat_1411_bak','flow_stat_1501','flow_stat_1502','flow_stat_1503','flow_stat_1504','flow_stat_1505','flow_stat_1506','flow_stat_1507','flow_stat_1508','flow_stat_1509','flow_stat_1510','flow_stat_1511','flow_stat_1512','hangzhoutest'
1 row in set (0.00 sec)
在从库上删除这些表：

执行这些drop语句就可以删除了
