My Experience With Table Names
When I first started working with databases, I found myself constantly confused about which table names were valid. I would often try to use spaces or special characters, only to be met with error messages. It wasn’t until I did some research and gained more experience that I fully understood the rules for creating valid table names.
Which of the Following Is a Valid Table Name?
A valid table name must follow certain rules. First, it can only contain letters, numbers, and underscores. It cannot contain spaces or special characters such as @, #, $, %, etc. Additionally, table names cannot begin with a number and must be unique within the database.
Step-by-Step Guide for Creating Valid Table Names
- Start with a letter or underscore
- Use only letters, numbers, and underscores
- Do not use spaces or special characters
- Make the name unique within the database
Top 10 Tips and Ideas for Creating Valid Table Names

- Avoid using reserved words in the table name
- Use singular nouns for table names

Pros and Cons of Valid Table Names
The primary advantage of using valid table names is that it ensures compatibility with the database software and makes it easier to write SQL queries. It also helps to avoid confusion and errors when working with multiple tables in the same database.
However, the downside is that it can be limiting in terms of creativity and may result in longer or less descriptive table names. It may also require some extra thought and effort to come up with a unique and appropriate name for each table.
