解决方案：
参考文件：11i – 12 Gather Schema Statistics fails with Ora-20001 errors after 11G database Upgrade (Doc ID 781813.1)
具体操作：
通过以下命令查询出有2条及以上条数的记录，
select table_name, column_name, count()
from FND_HISTOGRAM_COLS
group by table_name, column_name
having count() > 1;
备份后删除即可。
delete from FND_HISTOGRAM_COLS
where table_name = ‘&TABLE_NAME’
and column_name = ‘&COLUMN_NAME’
and rownum=1;
— Use following SQL to delete obsoleted rows
delete from FND_HISTOGRAM_COLS
where (table_name, column_name) in
(
select hc.table_name, hc.column_name
from FND_HISTOGRAM_COLS hc , dba_tab_columns tc
where hc.table_name =’&TABLE_NAME’
and hc.table_name= tc.table_name ()
and hc.column_name = tc.column_name ()
and tc.column_name is null
);
commit;
特别说明：日志中只报了3个表的错误，实际上如果只处理这3个表的问题，依然不能正常完成请求，需要将所有大于等于2的条数的数据删除。
