Beyond Basics: Exploring Advanced Table Naming in SQLite

2024-07-27

  • Valid characters: SQLite is very permissive. You can use letters, numbers, many symbols (like !, @, #, $, etc.), and even spaces (though spaces are not recommended).
  • Reserved names: The one restriction is that you cannot use names that start with "sqlite_". These names are reserved for internal use by SQLite itself.
  • Case sensitivity: SQLite considers table names case-sensitive. So, "Customers" and "customers" would be considered different tables.
  • Dots (periods): While technically allowed, it's best to avoid using dots (periods) in table names. They can make your SQL queries more complex to write.
  • Keywords and special characters: You can even use SQL keywords (like TABLE) or special characters within quotes (like '') for table names, but this is generally not recommended for readability.



  • customer_orders (clear, descriptive, uses lowercase with underscores)
  • user_data (simple and informative)
  • product_information (more descriptive)

Allowed, but not recommended:

  • 1st_customers (starts with a number, not ideal)
  • "New Customers" (uses spaces, can cause issues in queries)
  • specialChars!@#$ (uses special characters, less readable)
  • TABLE_data (uses a reserved keyword, can be confusing)
  • MyTable.extension (uses a dot, can complicate queries)



prefix = "user_"
user_id = 123

table_name = prefix + str(user_id)  # table_name becomes "user_123"

Taming the Hash: Effective Techniques for Converting HashBytes to Human-Readable Format in SQL Server

In SQL Server, the HashBytes function generates a fixed-length hash value (a unique string) from a given input string.This hash value is often used for data integrity checks (verifying data hasn't been tampered with) or password storage (storing passwords securely without the original value)...
