進出口創造一個程序給我一個輸出類似計數的範圍內犯規，得到所需的輸出
| Row | Voters | Households |

| Poll | NULL | NULL |
| <70% | 5000 | 2500 |
| <80% | 3500 | 2235 |
.....
| AV | NULL | NULL |

.....
| PAV | NULL | NULL |
| <70% | 1894 | 1201 |
所有的< 70％到< 100％

;
END
然後使用稱爲第一程序的第二程序
CREATE PROCEDURE `district_propensity`(IN target varchar(30))
COMMENT 'display demographics for district'
BEGIN
CALL district_Propensity_counts(target);
SELECT district_id, district_name FROM Districts WHERE district_id=target;
SELECT Row,
GROUP_CONCAT(IF (COL='Voters',Data,NULL))+0 AS 'Voters',
GROUP_CONCAT(IF (COL='Households',Data, NULL))+0 AS 'Households'
FROM Temp
GROUP BY ROW
ORDER BY SEQ;
END
但輸出我得到當我這樣做：
CALL district_propensity('3')
是一樣的東西
| Row | Voters | Households |
| Total | 15235 | 7250 |
| Poll | NULL | NULL |
| <90% | 4565 | 1 |
| AV | NULL | NULL |
| <100% | 668 | 0 |
| <70% | 1894 | 0 |
| <80% | 1434 | 3 |
| PAV | NULL | NULL |
完蛋了......我在想念所有的其他.. 但在選民列中的數字是正確的..它的計數是正確的，但錯過了很多..
對此的任何幫助是非常讚賞
