oracle 方便快捷的数据导入/导出命令
一、数据库的导出 :3种模式:全库导出,用户导出,表导出。 1. 命令行-全库导出 expuserid=system/system@My Oracle full=y file=(c:/tmp/2004020601.dmp,c:/tmp/2004020602.dmp, c:/tmp/2004020603.dmp) filesize=2GB log=c:/tmp/20040206.log 备注:该命令
一、数据库的导出 :3种模式:全库导出,用户导出,表导出。
1. 命令行-全库导出
exp userid=system/system@MyOracle full=y file=(c:/tmp/2004020601.dmp,c:/tmp/2004020602.dmp, c:/tmp/2004020603.dmp)
filesize=2GB
log=c:/tmp/20040206.log
备注:该命令导出全库数据,导出到多个文件中,每个文件最大2GB, exp 只生成最少的导出文件,譬如导出的数据不足2GB,
exp 只生成/tmp/2004020601.dmp 如果file 列表中的文件太少,
不能存放所有的导出数据,exp 会提示用户输入文件名,导出过程记录日志.
2. 命令行-完全导出
exp userid=system/system@MyOracle full=y inctype=complete
file=(/tmp/2004020601.dmp, /tmp/2004020602.dmp, /tmp/2004020603.dmp)
filesize=2GB log=/tmp/20040206.log
该命令完全导出全库数据,导出到多个文件中每个文件最大2GB,导出过程记录日志.
说明: 全库导出时,增量导出类型缺省为(complete)完全,所以1 和2导出的结果是完全一样的.
3. 命令行-累积导出
exp userid=system/system@MyOracle full=y inctype=cumulative
file=(/tmp/2004020601.dmp, /tmp/2004020602.dmp) filesize=2GB
log=/tmp/20040206.log
该命令累积导出全库数据,导出到多个文件中,每个文件最大2GB,导出过程记录日志.
说明: 如果选择了增量导出类型,则必需选择full=y,即只能在全库导出模式下进行完全累积或增量导出.
4. 命令行-增量导出
exp userid=system/system@MyOracle full=y inctype=incremental
file=(/tmp/2004020601.dmp, /tmp/2004020602.dmp) filesize=2GB
log=/tmp/20040206.log
该命令累积导出全库数据,导出到多个文件中,每个文件最大2GB,导出过程记录日志.
5. 命令行用户导出
exp userid=cams/cams@cams owner=cams file=(/tmp/2004020601.dmp,
/tmp/2004020602.dmp, /tmp/2004020603.dmp) filesize=2GB
log=/tmp/20040206.log
该命令导出cams 用户数据导出到多个文件中每个文件最大2GB 导出过程记录日志
6. 命令行表导出
exp userid=cams/cams@cams tables=(tbl_log, tbl_user_log) file=(/tmp/2004020601.dmp, /tmp/2004020602.dmp) filesize=2GB
log=/tmp/20040206.log
该命令导出cams 用户的两个表的数据,导出到多个文件中,每个文件最大2GB,导出过程记录日志.
二、数据库的导入
1、命令行导入表:有3种模式,a: tables(), b:full=y, c:fromuser(),touser()
a) imp userid=system/system@MyOracle file=c:/export/user_group.dmp log=c:/export/user_group.dmp tables(tbl_user,tbl_group)
b) imp userid=system/system@MyOracle file=c:/export/user_group.dmp log=c:/export/user_group.dmp full=y
c) imp userid=system/system@MyOracle file=c:/export/user_group.dmp log=c:/export/user_group.dmp fromuser=sanmyd
touser=system
2、命令行导入用户:
imp userid=system/system@MyOracle file=c:/export/user_group.dmp log=c:/export/user_group.dmp fromuser=(sanmyd) touser=(system)
3、命令行全库导入
imp userid=system/system@MyOracle file=c:/export/user_group.dmp log=c:/export/user_group.dmp full=y ignore=y
三、编写BAK文件,订时导出数据
@echo off
if exist "d:\smqdDB_bak" goto doExp
md "d:\smqdDB_bak"
:doExp
exp sanmyd/sanmyd@DEMO_192.168.2.102file='D:\smqdDB_bak\%date:~0,4%%date:~5,2%%date:~8,2%.dmp'

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.

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.

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.

An AWR report is a report that displays database performance and activity snapshots. The interpretation steps include: identifying the date and time of the activity snapshot. View an overview of activities and resource consumption. Analyze session activities to find session types, resource consumption, and waiting events. Find potential performance bottlenecks such as slow SQL statements, resource contention, and I/O issues. View waiting events, identify and resolve them for performance. Analyze latch and memory usage patterns to identify memory issues that are causing performance issues.

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.

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

Triggers in Oracle are stored procedures used to automatically perform operations after a specific event (insert, update, or delete). They are used in a variety of scenarios, including data verification, auditing, and data maintenance. When creating a trigger, you need to specify the trigger name, association table, trigger event, and trigger time. There are two types of triggers: the BEFORE trigger is fired before the operation, and the AFTER trigger is fired after the operation. For example, the BEFORE INSERT trigger ensures that the age column of the inserted row is not negative.
