sqlserver数据库注释符

SQL Server Comment Syntax.

In SQL Server, comments are used to add annotations and

explanations to your code. Comments are ignored by the

database engine and are not executed as part of the query.

There are two types of comments in SQL Server:

Single-line comments: Start with two hyphens (--) and

end at the end of the line.

Multi-line comments: Start with / and end with /.

Single-line comments.

Single-line comments are used to add short notes or

explanations to a specific line of code. For example:

sql.

-This line calculates the total sales for the month.

SELECT SUM(sales) FROM sales_table;

Multi-line comments.

Multi-line comments are used to add longer notes or

explanations that span multiple lines of code. For example:

sql.

/ This stored procedure calculates the total sales for

the month.

and updates the sales_summary table. /。

CREATE PROCEDURE GetMonthlySales.

AS.

BEGIN.
