sql server通过日志恢复数据库
--创建测试数据库Test create database Test on primary ( name=Test_data.mdf, filename=d:Test_data.mdf ) log on ( name=Test_data.ldf, filename=d:Test_data.ldf ) --创建测试表 create table Test.dbo.ta(id int) insert into Test.dbo.ta select id f
--创建测试数据库Test
create database Test
on primary
(
name=’Test_data.mdf’,
filename=’d:Test_data.mdf’
)
log on
(
name=’Test_data.ldf’,
filename=’d:Test_data.ldf’
)
--创建测试表
create table Test.dbo.ta(id int)
insert into Test.dbo.ta select id from sysobjects
--创建备份文件
backup database Test to disk=’d:Test.bak’ with format
--创建一个NDF文件
alter database Test
add file
(
name=’file’,
filename=’d:test.ndf’,
SIZE = 1MB
)
--关闭MSSQL服务,,然后删除NDF文件然后再打开MSSQL服务,此时Test数据库被疑置啦!
--恢复数据疑置
--首先备份日志文件
backup log Test to disk=’d:Test_log.bak’ with format,no_truncate
--利用文件组备份文件恢复被破坏的文件
restore database Test from disk=’d:Test.bak’ with Norecovery
--恢复日志文件
restore Log Test from disk=’d:Test_log.bak’ with RECOVERY
--TipS
--如果已经建立ndf文件的话那么恢复日志文件的话用下面的这句话
--只不过将with RECOVERY-->WITH REPLACE
restore Log Test from disk=’d:Test_log.bak’ WITH REPLACE

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())

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.

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.

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.

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.
