Scan error: unsupported Scan, storing driver.Value type <nil> into type *string

When I try to select Articles from a mysql database where the value of the column photo is NULL i get

sql: Scan error on column index 10: unsupported Scan, storing driver.Value type into type *string

func ArticlesAllText() ([]Article, error) {
    var err error
    var result []Article
    err = database.SQL.Select(&result, 
                "SELECT * FROM Article WHERE photo IS NULL")
    if err != nil {
        log.Println(err)
    }
    return result, standardizeError(err)
}

How can I fix this?

Use sql.NullString.

https://godoc.org/database/sql#NullString

Personally, I hate this solution, which is why I normalize my DB so that there are no NULLs.

Either change

var result []Article

To

var result []sql.NullString

Then take those results and make a []Article using the checks from the documentation.

Or in your struct, change

Photo *string

To

Photo sql.NullString

And deal with the annoyance of it being a struct instead of a *string
