var ErrQueryColumnsTagsMismtach = fmt.Errorf("query returned less columns than DB tags on struct")

ErrQueryColumnsTagsMismtach is returned when not all struct tags count does not match query column count This is a non-fatal error and can be ignored if the above is by design or planned This however acts as a fail-safe to avoid missing columns inside your select calls

Functions

func QueryRow

func QueryRow(ctx context.Context, tx querier, input interface{}, query string, args ...interface{}) error

QueryRow is a wrapper around Query that allows us to avoid the verbose Scan call

func Rows

func Rows(rows pgx.Rows, input interface{}) error

Rows takes a pgx.Rows and pointer to a slice of struct It will simplify scanning by using the db tags on structs to avoid verbose Scan calls
