我可以在数据库的不同存储过程中引用SQL Server中的CONSTANT这样的东西吗？

Question

I have this code which is part of a stored procedure. I have other stored procedures with similar snippets.

    INSERT INTO dbo.UserTest
    (  
        AdminTestId,
        Sequence,
        TestStatusId              
    ) 
    VALUES
    (
        @AdminTestId,
        @SEQ ,
        1
    ) 

Now I just realized the value of 1 should be a 2 for the testStatusId. I keep making these mistakes as I forget which number is which.

Is there some way that I can have a constant that I could reference that would be set in one place outside all of the stored procedures?

Ideally what I would like to do is something like this. But I don't want to declare the value of TestStatusId.Started at the top of every stored procedure.

    INSERT INTO dbo.UserTest
    (  
        AdminTestId,
        Sequence,
        TestStatusId              
    ) 
    VALUES
    (
        @AdminTestId,
        @SEQ ,
        @TestStatsusId.Started
    ) 

Answer 1

There is no concept of a constant in the context of a global value that can be referenced in your stored procedures. You can declare variables (although not constant) within your stored procedures: DECLARE @variableName <VariableType> = <Value> , but not outside of them.

The best option for having access to a value across multiple database objects is to create a table that contains your global values. In your stored procedure, you can then use a SELECT statement to retrieve the value for you or create a user-defined function that pulls back a value by some key (eg by name).

There aren't 'constants' in the typical programming sense, but you're working in a database; your tables are filled with constants. If this is an issue for you, you could have a table that has the numeric identifier in one column and a keyword representation in the other. Alternatively, you could have a function that does this conversion for you, and call it in the stored procedure.
