工作上碰到的Oracle Bug 6136074,一个10203上的bug,这种问题还是第一次碰到。
在10.2.0.3上,存在bug可能导致编译过程或视图失败,而失败的结果并不只是当前视图或过程不可用,而是可能影响整个数据字典,导致存储过程在执行时出现ORA-04068错误。
错误信息如下:
ORA-04068: existing state of packages has been discarded.
ORA-04065: not executed, altered or dropped stored procedure P_PACKAGE.P_PRO
ORA-06508: PL/SQL: could not find program unit being called: P_PACKAGE.P_PRO
ORA-06512: at line 1
这个问题对应的BUG信息为:Bug 6136074 - ORA-04068 / ORA-04065 ORA-06508 on VALID objects [ID6136074.8],导致问题的原因就是编译对象时导致PLSQL的依赖对象的时间戳发生不一致,从而导致问题的产生。
Oracle文档上给出了检查问题的SQL语句:
select do.obj# d_obj,do.named_name, do.type# d_type,
po.obj# p_obj,po.name p_name,
to_char(p_timestamp,'DD-MON-YYYY HH24:MI:SS') "P_Timestamp",
to_char(po.stime ,'DD-MON-YYYY HH24:MI:SS') "STIME",
decode(sign(po.stime-p_timestamp),0,'SAME','*DIFFER*') X
from sys.obj$ do, sys.dependency$ d, sys.obj$ po
where P_OBJ#=po.obj#(+)
and D_OBJ#=do.obj#
and do.status=1 /*dependent is valid*/
and po.status=1 /*parent is valid*/
and po.stime!=p_timestamp /*parent timestamp not match*/
order by 2,1;
通过这个脚本将获取的对象进行重新编译,可以解决这个问题,要避免问题的再次出现,,应该将数据库版本升级到10.2.0.4以上。

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

The article discusses using MySQL's ALTER TABLE statement to modify tables, including adding/dropping columns, renaming tables/columns, and changing column data types.

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.
