expdp 导出简单笔记
1、要创建Oracle可访问的目录必须赋予oracle:oinstall的权限
[root@oracle/]# chown -R oracle:oinstall /data1
2、切换到oracle用户
[root@oracle/]# su - oracle
3、创建expdp目录
[oracle@oracle/]$ cd /data1
[oracle@oracle data1]$ mkdir expdp
[oracle@oracle data1]$ cd expdp/
[oracle@oracle expdp]$ pwd
/data1/expdp
4、关联目录
SQL> create directory expdp as '/data1/expdp';
目录已创建。
5、赋予数据库用户mam40可直接读写的权限
SQL> grant read,write on directory expdp to mam40;
授权成功。
6、通过mam40用户导出数据库mam40对象的数据,将其存放到/data1/expdp 目录下。(注意:切换到操作系统命令行执行)
[oracle@oracle expdp]$ expdp mam40/password@wlw schemas=mam40 dumpfile=expdp001.dmp DIRECTORY=expdp version=10.2.0.5;

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Solutions to Oracle cannot be opened include: 1. Start the database service; 2. Start the listener; 3. Check port conflicts; 4. Set environment variables correctly; 5. Make sure the firewall or antivirus software does not block the connection; 6. Check whether the server is closed; 7. Use RMAN to recover corrupt files; 8. Check whether the TNS service name is correct; 9. Check network connection; 10. Reinstall Oracle software.

The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.

To stop an Oracle database, perform the following steps: 1. Connect to the database; 2. Shutdown immediately; 3. Shutdown abort completely.

SQL statements can be created and executed based on runtime input by using Oracle's dynamic SQL. The steps include: preparing an empty string variable to store dynamically generated SQL statements. Use the EXECUTE IMMEDIATE or PREPARE statement to compile and execute dynamic SQL statements. Use bind variable to pass user input or other dynamic values to dynamic SQL. Use EXECUTE IMMEDIATE or EXECUTE to execute dynamic SQL statements.

The steps to open an Oracle database are as follows: Open the Oracle database client and connect to the database server: connect username/password@servername Use the SQLPLUS command to open the database: SQLPLUS
