For SQL Server use [square_braces] around the name. This works in an ODBC connection too. For MySQL use `back_ticks`. Postgres, Oracle and several other RDBMs will apparently allow "double_quotes" to be used. Dotting the offending word onto the table name may also work.
Apr 16, 2024 · Table names should precisely convey the content or purpose of the data. So, we should avoid ambiguous or excessively truncated names. Whichever naming case we choose, we should apply it consistently.
Mar 9, 2011 · A simple approach to document table columns is to use the SQL Server Management Studio table designer. Fill in the Description field for each column. Then you can view table info with a query joining the sys.extended_properties table: -- list table columns.

We’ll use the same data model we’re using in this series. This time we won’t talk about the data itself, but rather about the database objects and the way they were named. I’ve already stated it in the intro, but more generally, a naming convention is a set of rules you decide to go with before you start modeling your database. You’ll apply these r...
Maybe the most important reason to use it is to simplify life to yourself. Databases rarely have a small number of tables. Usually, you’ll have hundreds of tables, and if you don’t want to have a complete mess, you should follow some organizational rules. One of these rules would be to apply a naming convention. It will increase the overall model r...
Hint: Use lower letters when naming database objects. For separating words in the database object name, use underscore
I would separate the naming convention for columns in a few categories: 1. A primary key column. You should usually have only 1 column serving as a primary key. It would be the best to simply name this column “id”. You should also name your PK constraint in a meaningful way. E.g., in our database, the PK of the call table is named call_pk 2. Foreig...
I won’t go into details here, but rather give a brief explanation of the naming convention I use when I do name these objects. Foreign keys. You should name them in such a manner that they uniquely and clearly describe what they are – which tables they relate. In our database, the foreign key that relates tables call and call_outcome is called call...
The naming convention is not a must, but (very) nice to have. Applying the rules you’ve set for the database design will help not only you but also others who will work with the database. Therefore, I would suggest that you use it and keep the database as organized as it could be.
With regards to writing good SQL code, there are a number of SQL naming conventions as well as best practices which should be followed. Use all lowercase for column and table names and to separate words with an underscore (“_”).
