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

The syntax differences between MySQL and SQL Server are mainly reflected in database objects, data types, SQL statements and other aspects. Database object differences include the storage engine and how filegroups are specified, and the creation of indexes and constraints. Data type differences involve differences in numeric types, character types, and date and time types. SQL statement differences are reflected in result set limitations, data insertion, update and delete operations, etc. Other differences include how identity columns, views, and stored procedures are created. Understanding these differences is important to avoid errors when using different database systems.

The problem that SQL Server cannot be reinstalled due to incomplete deletion can be solved by following the following steps: manually delete files and registry entries; use SQL Server installation and uninstall tools; use third-party uninstall tools; check Windows Event Viewer; restart the computer; reinstall SQL Server.

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

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.
