sqlite insert return rowid: The Simple yet Effective Solution

When it comes to SQLite, users often face the challenge of inserting data while avoiding conflicts with existing rows. In this case, using the `ON CONFLICT DO NOTHING` clause can be a useful solution. However, there is an even simpler approach that involves using the `RETURNING` keyword.

One common misconception about the `RETURNING` clause is that it returns nothing when a conflict occurs. But, what if you want to know the rowid of the last inserted or updated row? That's where this syntax comes in handy.

For instance, consider the following query: `INSERT INTO t VALUES ('dog') ON CONFLICT DO NOTHING RETURNING rowid, species`. This query inserts a new row into the table `t` with the value 'dog' if no conflict occurs. If a conflict does occur, it will return the rowid of the last inserted or updated row.

Another advantage of using this syntax is that you can avoid having to write complex queries. By simply inserting data and returning the rowid, you can simplify your code and make it more efficient.

However, there are some limitations to consider when using `RETURNING` with `ON CONFLICT DO NOTHING`. For instance, if you close the connection after inserting data, you will not be able to retrieve the rowid of the last inserted row. This is because the rowid is tied to the database connection that invoked the function.

In conclusion, using `sqlite insert return rowid` can be a powerful tool in your toolkit when working with SQLite databases. By simplifying your code and avoiding conflicts, you can make your life easier as a developer. Whether you're inserting data or updating existing rows, this syntax is definitely worth considering.
