Why did you use transactions in queries?

Hi,
I Want to ask you What the reason to wrap all queries with a transaction.
As I know, we should use transactions if we need the ability to rollback every change.
There is any reason to use it?

I find it easier to compose lower level helper functions if they all use a *sql.Tx. If there was a performance hit and I needed to optimize then I would consider removing them then.
