法SQL Server中的双数除法（sqlserver两数除）

Database admins and developers rely on SQL Server for the security, administration, and operation of important data. It’s one of the most powerful and versatile relational database server programs available on the market, and it offers advantages over other database platforms in many areas. One such feature is double division. Double division can be used to divide a set of values into two groups.

Double division in SQL Server is when two columns are divided based on a comparison of the two. For example, you might use double division to divide a table into two columns based on a specified value. Let’s take a look at how to do this with an example.

Say we have a table of student’s grades and we want to divide it into two columns: one for students who scored higher than 90 percent, and one for those who score lower than 90 percent. We can do this by using double division. Here’s the query that would do this:

SELECT

grade,

CASE WHEN grade>= 90 THEN ‘High’ ELSE ‘Low’ END AS grade_label

FROM

grades

In this query, we are dividing the table “grades” into two columns based on a comparison of the “grade” column. If the grade is 90 or higher, it is labeled “High”, otherwise, it is labeled “Low”.

Double division in SQL Server is an important tool for database administrators. It can be used to divide a set of data into two distinct groups based on a specified value. As you can see, it’s a straightforward and simple process.

Overall, double division in SQL Server is a great feature for data admins and developers who need to divide their data into two separate groups. It’s an incredibly powerful and flexible tool that can save a lot of time and effort, and it’s easy to use. If you’re looking for a way to quickly and easily divide your data into two groups, double division is a great choice.
