1. SQL Fiddle
SQL Fiddle is a tool for easy online testing and sharing of database problems and their solutions. If you do not know SQL or basic database concepts, this site is not going to be very useful to you. However, if you are a database developer, there are a few different use-cases of SQL Fiddle intended for you:
- You want help with a tricky query, and you’d like to post a question to a Q/A site
- You want to compare and contrast SQL statements in different database back-ends
- You do not have a particular database platform readily available, but you would like to see what a given query would look like in that environment
