Question

我知道那里有一千个类似的问题，但我已经有两周的时间试图为这个查询找到一个真正的解决方案。

此查询来自销售点计划。此查询与用户选择所需报表（期间，总计等）以及是否需要分组结果的表单相关。

这很不方便。查询是在VB.NET中生成的，我的意思是代码，它会根据用户的选择（不同的总数，句号，组等）而有所不同，所以通过这个问题的解决方案，我应该能够继续“创建” “通过代码表格的所有其他查询。

在这种情况下，此查询是按系列分组的总计查询。

大部分时间（> 99％）在发送数据中浪费（显示查询＃的配置文件）

表格如下：

查询是这样的：

SELECT  f.Nombre  ,SUM(sp.PrecioVenta*sp.Cantidad)  
FROM soldproduct sp, sales s, document doc, family f, product p 
WHERE s.idDocument = doc.idDocument AND doc.NoComputa = FALSE
AND p.idProduct = sp.idProduct AND sp.idSale = s.idSale 
AND p.idFamily = f.idFamily AND p.Borrado = FALSE 
AND s.Borrado = FALSE AND s.Historia = FALSE AND s.idTienda = 1 
AND s.FechaVenta BETWEEN '2013-01-01' AND '2014-01-01' GROUP BY f.idFamily;

我也尝试过这个（我还删除了文档表，以防它负责）

SELECT ProductFamily.Nombre, SUM(sp.PrecioVenta*sp.Cantidad) 
FROM 
(SELECT idSale FROM sales WHERE Borrado = FALSE AND Historia = FALSE AND idTienda = 1 
AND FechaVenta BETWEEN '2013-01-01' AND '2014-01-01') SalesidSale
JOIN
soldproduct sp
ON sp.idSale = SalesidSale.idSale
JOIN
(SELECT p.idProduct, p.idFamily, f.Nombre FROM product p, family f WHERE 
p.idFamily = f.idFamily AND p.Borrado = FALSE) ProductFamily
ON ProductFamily.idProduct = sp.idProduct
GROUP BY ProductFamily.idFamily;

它花费的时间非常大，它对EXPLAIN命令的输出是（第一次查询）：

我希望有人可以帮助我，我试图创建索引，子查询等等。但我不能得到低于40秒的任何东西，这太多了，我确定我做错了什么..

每个表的行数大约是：销售额：100,000 产品：20,000 家庭：35 已售产品：1,100,000 文件：4

非常感谢。

尝试这个我们试图利用短路的查询。

修改

SELECT f.Nombre, SUM(sp.PrecioVenta*sp.Cantidad) FROM soldproduct sp INNER JOIN sales s ON (s.idTienda = 1 AND AND s.Borrado = FALSE AND s.Historia = FALSE AND sp.idSale = s.idSale) INNER JOIN document doc ON (doc.NoComputa = FALSE AND s.idDocument = doc.idDocument) INNER JOIN family f ON (p.idFamily = f.idFamily) INNER JOIN product p ON (p.Borrado = FALSE AND p.idProduct = sp.idProduct) WHERE s.FechaVenta BETWEEN '2013-01-01' AND '2014-01-01' GROUP BY f.idFamily;
