import ( "fmt" "github.com/youtube/vitess/go/vt/vtgate/proto" ) func main() { // Create a new QueryResultList object resultList := &proto.QueryResultList{} // Set the number of rows affected resultList.RowsAffected = 5 // Add row data to the result list row1 := []byte("row1") row2 := []byte("row2") resultList.Rows = append(resultList.Rows, row1, row2) // Print the number of rows affected and the rows returned fmt.Printf("Rows affected: %d\n", resultList.RowsAffected) fmt.Printf("Rows returned: %v\n", resultList.Rows) // Create an Error object err := &proto.Error{ Message: "An error occurred", SqlState: "HY000", ErrCode: 1001, } // Print the error message, SQL state, and error code fmt.Printf("Error message: %s\n", err.Message) fmt.Printf("SQL state: %s\n", err.SqlState) fmt.Printf("Error code: %d\n", err.ErrCode) }In this example, we create a QueryResultList object and set the number of rows affected and the rows returned. We then create an Error object and set the error message, SQL state, and error code. Finally, we print out the relevant information for both objects.
