1.--直接跨数据库连接
OPENDATASOURCE('SQLOLEDB','Server=10.252.35.194\GZ,1435;Uid=mrms2;pwd=mrms1234')。mrmsv3_backup_im.[dbo].[s2] t
其中变量为IP、 账号、密码、 数据库名、账户名、表名
2.--建立远程访问连接
比如我现在在本机,要方便的访问10.244.8.193(sa,1),其中sa/1分别为账号密码
就需要在本机执行下列命令:
exec sp_addlinkedserver 'bowinserver', '', 'SQLOLEDB', '10.244.8.193'
exec sp_addlinkedsrvlogin 'bowinserver', 'false',null, 'sa', '1'
其中变量为自定义名、IP、账号、密码
命令中bowinserver即自定义名,接下来我要访问10.244.8.193(sa,1) 中mrmsv3_cf_dev数据库的cf_user表:
SELECT * FROM bowinserver.mrmsv3_cf_dev.dbo.cf_user

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

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.

The format of the Navicat connection URL is: protocol://username:password@host:port/database name? Parameters, which contain the information required for the connection, including protocol, username, password, hostname, port, database name and optional parameter.

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.

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.

No localhost server in Navicat may be due to the database service not starting, incorrect server alias configuration, firewall blocking access, alias and instance mismatch, or remote connection issues. Workarounds include starting the database service, configuring the server alias correctly, allowing inbound connections on port 1433, matching the server alias to the instance, and checking the remote connection configuration. If this persists, seek help from your system administrator or database vendor.
