尝试像下面那样为每个组生成行号，然后将行数限制为im以下，以显示每组2个结果。
Select `marka_name`, `model_name`, `kuzov`, `mileage`, `year`, `rate`from ( SELECt @row_num := IF(@prev_value=main.Model_Name,@row_num+1,1) AS RowNumber, main.*, @prev_value := main.Model_Name FROM main, (SELECT @row_num := 1) x, (SELECT @prev_value := '') y WHERe ( (marka_name = 'SUBARU' AND model_name = 'IMPREZA' AND (kuzov = 'GC8' OR kuzov = 'GF8')) OR (marka_name = 'MAZDA' AND model_name = 'RX-7' AND kuzov = 'FD3S') OR (marka_name = 'MITSUBISHI' AND model_name = 'LANCER' AND (kuzov = 'CN9A' OR kuzov = 'CP9A')) OR (marka_name = 'NISSAN' AND model_name = 'SKYLINE' AND (kuzov = 'ER34' OR kuzov = 'BCNR33')) OR (marka_name = 'NISSAN' AND model_name = 'SILVIA' AND kuzov = 'S14') OR (marka_name = 'TOYOTA' AND model_name = 'CELICA' AND kuzov = 'ST205') OR (marka_name = 'TOYOTA' AND model_name = 'ARISTO' AND kuzov = 'JZS161') OR (marka_name = 'MITSUBISHI' AND model_name = 'DELICA' AND (kuzov = 'PE8W' OR kuzov = 'PD8W' OR kuzov = 'PF8W')) ) AND (rate != 'RA' AND rate != 'RR' AND rate != 'A1' AND rate != 'A' AND rate != 'R' AND rate >= '3') AND (mileage >= 0 AND mileage <= 150000) AND (year >= 1990 AND year <= 1998) ORDER BY model_name, mileage ASC, rate DESC) A where A.RowNumber<=2
要获得每组2条以上的记录，只需更改最后一个子句的位置（如果您每组要获得10条结果）。写在A.RowNumber <= 10的地方
