Functions ¶
func IsQueryCancelled ¶
IsQueryCancelled returns true if an error is a query cancellation.
func IsUniqueViolation ¶
IsUniqueViolation returns true if an error is a unique violation.
func MigrateSome ¶
MigrateSome will apply migration m and all unapplied migrations with earlier ids. To ensure a single migration is executed, run sql-migrate.PlanMigration and call MigrateSome for each migration returned.
Types ¶
type DestProvider ¶
type DestProvider interface {
// To returns list of pointers.
// It is not an idempotent operation and each call will return a new list.
To() []interface{}
}
DestProvider returns list of pointers that will be used to scan values into.
type ListenHandler ¶
type ListenHandler interface {
// Notification would be triggered once a new notification received.
Notification(Notification)
// Disconnect would be triggered once a connection to remote service is lost.
// Passed in error will never be nil and will contain cause of the disconnection.
Disconnect(error)
// Connected would be triggered once a connection to remote service is established.
Connected()
}
ListenHandler contains a set of methods that would be called on corresponding notifications received.
type Notification ¶
type Notification struct {
// Channel is a name of the receiving channel.
Channel string
// Payload is a payload of the notification.
Payload string
}
Notification represent a notification from the database.
type Querier ¶
type Querier interface {
QueryContext(ctx context.Context, query string, args ...interface{}) (*sql.Rows, error)
QueryRowContext(ctx context.Context, query string, args ...interface{}) *sql.Row
ExecContext(ctx context.Context, query string, args ...interface{}) (sql.Result, error)
}
Querier is an abstraction on *sql.DB and *sql.Tx that allows to use their methods without awareness about actual type.
type StringArray ¶
StringArray is a wrapper that provides a helper methods.
func (StringArray) Slice ¶
func (sa StringArray) Slice() []string
Slice converts StringArray into a slice of strings. The array element considered to be a valid string if it is not a null.
type StringProvider ¶
type StringProvider []*string
StringProvider allows ScanAll to read all rows and return the result as a slice.
func (*StringProvider) To ¶
func (p *StringProvider) To() []interface{}
To returns a list of pointers that will be used as a destination for scan operation.
func (*StringProvider) Values ¶
func (p *StringProvider) Values() []string
Values returns list of values read from *sql.Rows
type Uint64Provider ¶
type Uint64Provider []*uint64
Uint64Provider allows to use it with ScanAll function to read all rows into it and return result as a slice.
func (*Uint64Provider) To ¶
func (p *Uint64Provider) To() []interface{}
To returns a list of pointers that will be used as a destination for scan operation.
func (*Uint64Provider) Values ¶
func (p *Uint64Provider) Values() []uint64
Values returns list of values read from *sql.Rows
