在转储的数据库中转储存储程序(函数和程序)。使用---routines产生的输出包含CREATE PROCEDURE和CREATE FUNCTION语句以重新创建子程序。但是,这些语句不包括属性,例如子程序定义者或创建和修改时间戳。这说明当重载子程序时,对它们进行创建时定义者应设置为重载用户,时间戳等于重载时间。
如果你需要创建的子程序使用原来的定义者和时间戳属性,,不使用--routines。相反,使用一个具有mysql数据库相应权限的MySQL账户直接转储和重载mysql.proc表的内容。
show procedure status;
show create procedure autoinsert;
DELIMITER ;;
CREATE PROCEDURE `autoinsert`()
begin
declare i int;
set i=1;
while(iinsert into t10 values (i,'name');
set i=i+1;
end while;
END;;

备份mysqldump -u root -p123 --socket=/usr/local/mysql1/var/mysql.sock -R --no-data --no-create-db --no-create-info --all-database > /root/mysqllog/test.sql
mysqldump -u root -p123 --socket=/usr/local/mysql1/var/mysql.sock mysql proc > /root/mysqllog/test.sql
还原source /root/mysqllog/test.sql

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

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

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())

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.

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.

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.

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.

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.
