SQL Server database penetration from the basics Create lab environment Next, I will provide an example to demonstrate the basic steps for creating an SQL Server. Download Microsoft SQL Server Express and Install SQL Server Management Studio. Follow the Wizard to Install SQL Server step by step. Make sure that the Hybrid Authentication mode is enabled and related services are enabled locally. Use the "SA" account to log on to SQL Server and set it when installing and using the SQL Server Manageme

In general, there are two ways to sort data: Use the sort component, and use the TSQL command to ORDER BY. Sorting using the sort component is a blocking operation for SSIS, which means that the SSIS component must wait until all the data is loaded into memory to perform a sort operation on the data according to a specific field. However, if you use the ORDER BY clause of the TSQL command to perform a sort

When actually doing the project encountered a problem: the database table stores each type of train ticket sales number of each train station, but some railway stations may not sell moving tickets or high-speed rail tickets, the final result should be as shown in Figure 2, do not sell the type of train tickets out of the air. This paper uses master.dbo.spt_values to generate the maximum number of column headers, and then the case when the implementation of each type of train ticket statistics.

In Oracle, when auto-incrementing sequence is reset to initial 1, it is deleted and rebuilt. This method has many drawbacks, functions and stored procedures dependent on it will become invalid and need to be re-compiled. However, there is a clever way to do this without deleting it. You can use the step size parameter to first find the nextval of sequence, remember to change the increment value to the negative value (which goes in turn), and then change it back. Assume that the sequence name to
