ORA-22868: table with LOBs contains segments in different ta
今天做实验的时候创建了一个表空间lob_tbs, 并且在该表空间上创建了一个包含大对象字段的表lob_tab。 当实验结束想要删除该表空间
今天做实验的时候创建了一个表空间lob_tbs, 并且在该表空间上创建了一个包含大对象字段的表lob_tab。 当实验结束想要删除该表空间时报错ORA-22868。使用Oracle的帮助信息oerr ora 22868很容易定位问题的原因,根据提示先删除含有大字段的表,,然后在删除该表空间就可以了。
问题还原如下:
1. 创建表空间lob_tbs
create tablespace lob_tbs datafile ‘/dbfiles/lob_tbs01.dbf’ size 100m
autoextend on extent management local;
2. 在users表空间创建表lob_tab, 大字段列存储在lob_tbs表空间中
create table lob_tab (id int, doc blog) tablespace users
lob(doc) store as securefile(tablespace lob_tbs compress high deduplicate);
3. 删除表空间lob_tbs报错ORA-22868
drop tablespace lob_tbs including contents;
drop tablespace lob_tbs including contents
*
ERROR at line 1:
ORA-22868: table with LOBs contains segments in different tablespaces
使用oerr帮助信息查到提示drop these tables and reissure drop tablespace. 先删除表,然后在删除表空间
enmoedu1*PROD1 ~ $ oerr ora 22868
22868, 00000, "table with LOBs contains segments in different tablespaces"
// *Cause: An attempt was made to drop a tablespace which contains the
// segment(s) for the LOB columns of a table but does not contain
// the table segment.
// *Action: Find table(s) with LOB columns which have non-table segments in
// this tablespace. Drop these tables and reissue drop tablespace.
HR@PROD1 > drop table lob_tab;
SYS@PROD1 > drop tablespace lob_tbs;
Tablespace dropped.
遇到报错信息时,使用oerr可提供说明,甚至给出指导性建议来帮助我们处理问题。

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

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.

Article discusses configuring SSL/TLS encryption for MySQL, including certificate generation and verification. Main issue is using self-signed certificates' security implications.[Character count: 159]

Article discusses strategies for handling large datasets in MySQL, including partitioning, sharding, indexing, and query optimization.

The article discusses dropping tables in MySQL using the DROP TABLE statement, emphasizing precautions and risks. It highlights that the action is irreversible without backups, detailing recovery methods and potential production environment hazards.

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.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
