导入导出实例:

用户的创建参考:http://blog.csdn.net/gateway6143/article/details/41212823
一、数据导出:
1、 将数据库TEST完全导出,用户名system 密码manager 导出到D:\daochu.dmp中
exp system/manager@TEST file=d:\daochu.dmp full=y
2、 将数据库中system用户与sys用户的表导出 (含表、存储过程、视图等)
exp system/manager@TEST file=d:\daochu.dmp owner=(system,sys)
3、 将数据库中的表table1 、table2导出
exp system/manager@TEST file=d:\daochu.dmp tables=(table1,table2)
4、 将数据库中的表table1中的字段filed1以"00"打头的数据导出
exp system/manager@TEST file=d:\daochu.dmp tables=(table1) query=\" where filed1 like '00%'\"
上面是常用的导出,对于压缩我不太在意,用winzip把dmp文件可以很好的压缩。
不过在上面命令后面 加上 compress=y 就可以了
二、数据的导入
1、将D:\daochu.dmp 中的数据导入 TEST数据库中。
imp system/manager@TEST file=d:\daochu.dmp
上面可能有点问题,因为有的表已经存在,然后它就报错,对该表就不进行导入。
在后面加上 ignore=y 就可以了。
2 将d:\daochu.dmp中的表table1 导入
imp system/manager@TEST file=d:\daochu.dmp tables=(table1)
基本上上面的导入导出够用了。不少情况我是将表彻底删除,然后导入。
注意:
你要有足够的权限,权限不够它会提示你。
数据库是可以连上的,用tnsping TEST 来判断数据库TEST能否连上。

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

Using the database callback function in Golang can achieve: executing custom code after the specified database operation is completed. Add custom behavior through separate functions without writing additional code. Callback functions are available for insert, update, delete, and query operations. You must use the sql.Exec, sql.QueryRow, or sql.Query function to use the callback function.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

Use the DataAccessObjects (DAO) library in C++ to connect and operate the database, including establishing database connections, executing SQL queries, inserting new records and updating existing records. The specific steps are: 1. Include necessary library statements; 2. Open the database file; 3. Create a Recordset object to execute SQL queries or manipulate data; 4. Traverse the results or update records according to specific needs.

Through the Go standard library database/sql package, you can connect to remote databases such as MySQL, PostgreSQL or SQLite: create a connection string containing database connection information. Use the sql.Open() function to open a database connection. Perform database operations such as SQL queries and insert operations. Use defer to close the database connection to release resources.

PHP database connection guide: MySQL: Install the MySQLi extension and create a connection (servername, username, password, dbname). PostgreSQL: Install the PgSQL extension and create a connection (host, dbname, user, password). Oracle: Install the OracleOCI8 extension and create a connection (servername, username, password). Practical case: Obtain MySQL data, PostgreSQL query, OracleOCI8 update record.
