Types ¶
type Transaction ¶
type Transaction interface {
Exec(query string, args ...interface{}) (sql.Result, error)
Prepare(query string) (*sql.Stmt, error)
Query(query string, args ...interface{}) (*sql.Rows, error)
QueryRow(query string, args ...interface{}) *sql.Row
QueryRowContext(ctx context.Context, query string, args ...interface{}) *sql.Row
}
Transaction is an interface that models the standard transaction in `database/sql`.
To ensure `TxFn` funcs cannot commit or rollback a transaction (which is handled by `WithTransaction`), those methods are not included here.
type TxFn ¶
type TxFn func(Transaction) error
TxFn is a function that will be called with an initialised `Transaction` object that can be used for executing statements and queries against a database.
