Functions ¶

func Get ¶

func Get(ctx context.Context, queryer Queryer, dest interface{}, query string, args ...interface{}) error

func ScanFlat ¶

func ScanFlat(r pgx.Rows, dest interface{}) error

func ScanStruct ¶

func ScanStruct(r pgx.Rows, dest interface{}) error

ScanStruct scans a pgx.Rows into destination struct passed by reference based on the "db" fields tags. This is workaround function for pgx.Rows with single row as pgx/v4 does not allow to get row metadata from pgx.Row - see https://github.com/jackc/pgx/issues/627 for details.

If there are no rows pgx.ErrNoRows is returned. If there are more than one row in the result - they are ignored. Function call closes rows, so caller may skip it.

func ScanStructs ¶

func ScanStructs(r pgx.Rows, dest interface{}) error

ScanStructs scans a pgx.Rows into destination structs list passed by reference based on the "db" fields tags

func Select ¶

func Select(ctx context.Context, queryer Queryer, dest interface{}, query string, args ...interface{}) error

func SelectFlat ¶

func SelectFlat(ctx context.Context, queryer Queryer, dest interface{}, query string, args ...interface{}) error

Types ¶

type Queryer ¶

type Queryer interface {
	Query(ctx context.Context, sql string, args ...interface{}) (pgx.Rows, error)
	QueryRow(ctx context.Context, sql string, args ...interface{}) pgx.Row
}
