ORA-08102这种错误说明索引或表出现了数据不一致的,索引上记录的键值和表里的数据不一致,引起访问失败,一般重建下索引就可以解
今天两次遇到ORA-08102的错误,在删除表的数据时
在执行如下语句时:
delete from tb_ware w where w.issue like '%04%';
遇到下面的错;
ORA-08102:index key not found,obj#57848,file 6, block 6324(2)

ORA-08102这种错误说明索引或表出现了数据不一致的,索引上记录的键值和表里的数据不一致,引起访问失败,一般重建下索引就可以解决
解决方法一:
SELECT owner, object_name, object_type
FROM Dba_Objects
WHERE object_id IN (57848);
可以查出object_name的名字,发现是表TB_WARE的索引,然后重建索引
alter index PK_TB_WARE rebuild online; (记得要用rebuild online ,因为他会重新读表来创建索引,而rebuild可能会读取原先的索引段而不会去读表)
注意,这个时候千万不要人为终止,如果你真的那样的话你会遇到ora-08104
如果还不能解决,就删除重新创建
select index_name,column_name from all_ind_columns
where index_name='PK_TB_WARE';
drop index PK_TB_WARE;
create index PK_TB_WARE on tb_ware(id);
解决方法二:
analyze table t validate structure cascade
检查表里的行数据的完全性,并检查表或者索引的结构,并把分析过的结果写入INDEX_STATS 数据字典中
这个方法我没有尝试,我尝试再让问题重现,尝试好几次也没有在出现
---------------------------------
现在回到我的问题上,我在rebuild online一个索引后,,它又提示下一个索引有问题,我索性就把这个表所有的索引都rebuild online
查出这个表的索引
select * from user_indexes t where t.table_name= upper('tb_ware')
组装成下面的语句执行:
alter index PK_TB_WARE rebuild online;
alter index AK_TB_WARE rebuild online;
alter index IDX_TB_WARE_PRINTSTATE rebuild online;
alter index IDX_WARE_END_TIME rebuild online;
alter index IDX_WARE_LOTTERY_ID rebuild online;
alter index IDX_WARE_LOTTERY_STATE rebuild online;
alter index IDX_WARE_TEAM_NAME rebuild online;
再次使用这个表,或到alert.log里就没有ORA-08102的错误了

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
