SqlServer开发利器—SQL Prompt5

The import steps are as follows: Copy the MDF file to SQL Server's data directory (usually C:\Program Files\Microsoft SQL Server\MSSQL\DATA). In SQL Server Management Studio (SSMS), open the database and select Attach. Click the Add button and select the MDF file. Confirm the database name and click the OK button.

For objects with the same name that already exist in the SQL Server database, the following steps need to be taken: Confirm the object type (table, view, stored procedure). IF NOT EXISTS can be used to skip creation if the object is empty. If the object has data, use a different name or modify the structure. Use DROP to delete existing objects (use caution, backup recommended). Check for schema changes to make sure there are no references to deleted or renamed objects.

HQL and SQL are compared in the Hibernate framework: HQL (1. Object-oriented syntax, 2. Database-independent queries, 3. Type safety), while SQL directly operates the database (1. Database-independent standards, 2. Complex executable queries and data manipulation).

To view the SQL Server port number: Open SSMS and connect to the server. Find the server name in Object Explorer, right-click it and select Properties. In the Connection tab, view the TCP Port field.

When the SQL Server service fails to start, here are some steps to resolve: Check the error log to determine the root cause. Make sure the service account has permission to start the service.

If you accidentally delete a SQL Server database, you can take the following steps to recover: stop database activity; back up log files; check database logs; recovery options: restore from backup; restore from transaction log; use DBCC CHECKDB; use third-party tools. Please back up your database regularly and enable transaction logging to prevent data loss.
