没有转去销售表的时候,数据是正确的;
'2013-01-07':
+------------+---------+---------+
| sum(total) | sum(aa) | DEP_BF |
+------------+---------+---------+
| 100.0000 | 50.0000 | 0.0000 |
+------------+---------+---------+

'2013-01-08':
+------------+---------+---------+
| sum(total) | sum(aa) | DEP_BF |
+------------+---------+---------+
| 100.0000 | 50.0000 | 50.0000 |
+------------+---------+---------+

当在'2013-01-08'时,把预定表的数据转到销售表的时候,
'2013-01-07':
+------------+---------+---------+
| sum(total) | sum(aa) | DEP_BF |
+------------+---------+---------+
| 200.0000 |150.0000 | 0.0000 |
+------------+---------+---------+

'2013-01-08':
+------------+---------+---------+
| sum(total) | sum(aa) | DEP_BF |
+------------+---------+---------+
| 100.0000 | 50.0000 | 50.0000 |
+------------+---------+---------+

正确的应该是:
'2013-01-07':
+------------+---------+---------+
| sum(total) | sum(aa) | DEP_BF |
+------------+---------+---------+
| 150.0000 | 150.0000 |0.0000 |
+------------+---------+---------+

'2013-01-08'(150是在01-08号之前收的算DEP_BF):
+------------+---------+---------+
| sum(total) | sum(aa) | DEP_BF |
+------------+---------+---------+
| 200.0000 | 50.0000 | 150.0000|
+------------+---------+---------+

没看明白 什么转去

[lxq19851204]

就是2张单为预定状态的时候,DEP_BF为0 当在01-08转去销售表的时候,02-07收的钱就变为DEP_BF=150.

t5表没数据？ 最后的sql执行报错

[lxq19851204]

t5与t2的数据一样

[ACMAIN_CHM]

没看懂想实现什么。 建议不要用销售之类的业务术语，直接描述你的表原来是什么样的数据，期望的结果是什么样。

[lxq19851204]

SELECT aa.MenuID, aa.BusinessDate,C.total,SUM(aa) as aa,IF(DEP_BF1 IS NULL,0,MAX(c.total)-SUM(aa)) AS DEP_BF

 Inner JOIN t3 c
 ON c.menuid=aa.menuid  Where c.TransStatus=2  Group by c.menuid
'************
上面这个语句需要改

更新t3的transstatus全部为2
查询7号:
+--------+---------------------+----------+----------+--------+
| MenuID | BusinessDate        | total    | aa       | DEP_BF |
+--------+---------------------+----------+----------+--------+
|    182 | 2013-01-07 00:00:00 | 100.0000 |  50.0000 |      0 |
|    184 | 2013-01-07 00:00:00 | 100.0000 | 100.0000 |      0 |
+--------+---------------------+----------+----------+--------+
查询8号的数据要为:
+--------+---------------------+----------+----------+--------+
| MenuID | BusinessDate        | total    | aa       | DEP_BF |
+--------+---------------------+----------+----------+--------+
|    182 | 2013-01-08 00:00:00 | 100.0000 |  50.0000 |50.0000 |
|    184 | 2013-01-08 00:00:00 | 100.0000 |   0.0000 |100.0000|
