package database/sql/driver
Execer is an optional interface that may be implemented by a Conn.
If a Conn does not implement Execer, the sql package's DB.Exec will first prepare a query, execute the statement, and then close the statement.
Exec may return ErrSkip.
Golang database/sql/driver.Execer type usage example
// creates a new wrap and registers it with the name "debug"
wrap := dbwrap.New("debug", pqdrv(0))
...
// is used instead of conn.Exec
wrap.HandleExec = func(exec driver.Execer, query string, args []driver.Value) (driver.Result, error) {
fmt.Println("exec: ", query)
// do the real Exec and return the result
return exec.Exec(query, args)
}
