Naming conventions for SQL Server stored procedures
By: Greg Robidoux
One good thing to do for all of your SQL Server objects is to come up with a naming convention to use. There are not any hard and fast rules, so this is really just a guideline on what should be done.
SQL Server uses object names and schema names to find a particular object that it needs to work with. This could be a table, stored procedure, function ,etc...
It is a good practice to come up with a standard naming convention for you objects including stored procedures.
Do not use sp_ as a prefix
One of the things you do not want to use as a standard is "sp_". This is a standard naming convention that is used in the master database. If you do not specify the database where the object is, SQL Server will first search the master database to see if the object exists there and then it will search the user database. So avoid using this as a naming convention.
Standardize on a Prefix
It is a good idea to come up with a standard prefix to use for your stored procedures. As mentioned above do not use "sp_", so here are some other options.
To be honest it does not really matter what you use. SQL Server will figure out that it is a stored procedure, but it is helpful to differentiate the objects, so it is easier to manage.
So a few examples could be:
Again this is totally up to you, but some standard is better than none.
Naming Stored Procedure Action
I liked to first give the action that the stored procedure takes and then give it a name representing the object it will affect.
So based on the actions that you may take with a stored procedure, you may use:
So here are a few examples:
Another option is to put the object name first and the action second, this way all of the stored procedures for an object will be together.
Again, this does not really matter what action words that you use, but this will be helpful to classify the behavior characteristics.
Naming Stored Procedure Object
The last part of this is the object that you are working with. Some of these may be real objects like tables, but others may be business processes. Keep the names simple, but meaningful. As your database grows and you add more and more objects you will be glad that you created some standards.
So some of these may be:
- uspInsertPerson - insert a new person record
- uspGetAccountBalance - get the balance of an account
- uspGetOrderHistory - return list of orders
Another thing to consider is the schema that you will use when saving the objects. A schema is the a collection of objects, so basically just a container. This is useful if you want to keep all utility like objects together or have some objects that are HR related, etc...
This logical grouping will help you differentiate the objects further and allow you to focus on a group of objects.
Here are some examples of using a schema:
To create a new schema you use the CREATE SCHEMA command
Here is a simple example to create a new schema called "HR" and giving authorization to this schema to "DBO".
CREATE SCHEMA [HumanResources] AUTHORIZATION [dbo]
Putting It All Together
So you basically have four parts that you should consider when you come up with a naming convention:
Take the time to think through what makes the most sense and try to stick to your conventions.
