Drop user cascade failed ORA-00604 ORA-02429 处理一例
我们知道drop user 带cascade会将所属的表空间和其他关联数据库对象一起删除,而这也说明正要被删除的对象和其他对象之间存在主外
在删除索引、表、或者表空间及用户等数据库对象或者用户的时候,有时候会遇到入下错误:
SQL> drop user Oracle cascade;
drop user oracle cascade;
*
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-02429: cannot drop index used for enforcement of unique/primary key
我们知道drop user 带cascade会将所属的表空间和其他关联数据库对象一起删除,而这也说明正要被删除的对象和其他对象之间存在主外键约束关联的问题,所以需要查询该对象存在哪些约束并删除之
SQL>select 'alter table '||owner||'.'||table_name||' drop constraint '||constraint_name||' ;'
from dba_constraints
where constraint_type in ('U', 'P')
and (index_owner, index_name) in
(select owner, segment_name
from dba_segments
where onwner = 'ORACLE');
alter table w.table_name drop constraint PK_ID ;
alter table x.table_name drop constraint FK_UID ;
SQL> alter table w.table_name drop constraint pk_id;
table altered
SQL>alter table x.table_name drop constraint fk_uid;
table altered
SQL> drop user ORACLE cascade;
User dropped.
--用户删除成功
查询出结果并删除即可drop user oralce cascade了,因为这个报错比较典型,网上还看到过很多种延伸出来的问题原因,,记录之。

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.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

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 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 is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

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.
