1.数据泵可以导出表,,表空间,用户schema,数据库
注意:导出表空间和数据库要求用户必须具有DBA 角色或EXP_FULL_DATABASE 角色
grant connect,resource,exp_full_database,create any directory to sfcp;
2.创建目录对象
create directory dump_dir as '/home/Oracle';
3.给用户授予实际路径读/写操作权限(一般不用写)
grant read,write on directory dump_dir to sfcp;
4.导出表
expdp sfcp/sfcp dumpfile=sfcp_table.dmp directory=dump_dir tables=ssdp_log,ssdp_area
5.导出表空间
expdp sfcp/sfcp dumpfile=sfcp_2_3_idx.dmp directory=dump_dir tablespaces=sfcp,sfcp2,sfcp3,sfcp_idx
转储文件名添加当前日期
expdp sfcp/sfcp dumpfile=[$Today]sfcp_2_3_idx.dmp directory=dump_dir tablespaces=users,example
日志文件名添加当前日期
expdp leo1/leo1 dumpfile=[$Today]sfcp_2_3_idx.dmp logfile=[$Today]expdp.log directory=dump_dir tablespaces=users,example
环境变量设置export Today=$(date +%Y-%m-%d)
6.导出用户schema
expdp sfcp/sfcp dumpfile=sfcp.dmp directory=dump_dir schemas=sfcp
7.导出数据库
expdp sfcp/sfcp dumpfile=base.dmp directory=dump_dir full=y
8.导出查询条件
expdp sfcp/sfcp dumpfile=sfcp_where.dmp directory=dump_dir tables=ssdp_log query='where iid=100'
注:Today环境变量不同使用方法,临时设置reboot之后失效请注意
export Today=$(date +%Y-%m-%d)
echo "$Today"
2013-11-26
echo "$Today"123
2013-11-26123
echo "$Today-123"
2013-11-26-123
echo "[$Today]sfcp_2_3_idx.dmp"
[2013-11-26]sfcp_2_3_idx.dmp
echo [$Today]sfcp_2_3_idx.dmp
[2013-11-26]sfcp_2_3_idx.dmp
touch "[$Today]sfcp_2_3_idx.dmp"
[2013-11-26]sfcp_2_3_idx.dmp

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.

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.

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.

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.

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.
