Hi,
My name is Eugene and we made this little online SQL language trainer to help non-programmers to learn basic SQL queries. And more important, it shows the result of query entered.
Any suggestions and comments are welcome!
and many thanks for all the suggestion already made! And seems like we should better remove MySQL specific command from the very first question.
- evo_9 8y agoMaybe not remove it but perhaps have a choice of SQL 'flavor'. That would be very useful, aka user chooses Oracle, MySQL, MS-SQL, etc.
- kevinjoling 8y agoNice! Would love to see this, but for complex queries.
- rolleiflex 8y agoHey Eugene! In the last question, it seems you can get the same result by doing top 3, or limit 3, but only limit 3 is accepted as valid. You might either want to, if there's a valid reason for the distinction (execution order?), want to highlight as the difference between top and limit, or if there isn't, accept both.
- eumm 8y agothanks for the suggestion! yes, definitely will need to update the way it checks for correct answer as there can be multiple variations.
- z3t4 8y agoMake sure it's virtualized/sandboxed, SQL basically guarantees HDD write access.
