Golang sqlx.Get: Checking for no rows returned

When working with “github.com/jmoiron/sqlx” to fetch rows from the database, the Get function returns an error if there is an error with your query, or if no rows are returned.

Instead of reading the documentation, I had been testing for this with:

err = db.Get(&user, GET_USER_BY_ID, userId)
if err.Error() != "sql: no rows in result set" {
  return err
}
... handle missing user ...

I had never spent the time to figure out where the message was coming from, but today I finally got around to looking for the right way to do this, and found a helpful comment:

err = db.Get(&user, GET_USER_BY_ID, userId)
if err != sql.ErrNoRows {
  return err
}
... handle missing user ...

Using this strategy, you protect yourself from any change to the text of the error, and save quite a bit of noise in your code. Hope this helps!
