Possible disadvantages

  As a web-based tool, SQL Fiddle requires an internet connection to access its features, which may not be suitable for offline work or conditions with limited connectivity.
• No Persistence
  Data and schemas on SQL Fiddle are not persistent, meaning they can be lost over time or due to maintenance, making it unreliable for long-term storage or ongoing project work.
• Limited Functionality
  SQL Fiddle may not support the full feature set or latest features of all database systems, potentially limiting its use for testing advanced or system-specific queries.
