Question

我们有一个数据集，其中包含一个名为＆＃34;取消＆＃34;这是一个布尔字段。我希望报告有一个名为@includecancelled的参数作为布尔值。用户可以将其标记为True或False，以控制是否在报告中包含已取消的记录。到目前为止，我还没有找到办法做到这一点。这是我目前所拥有的基本概要：

SELECT TOP 10 COUNT (table1.field1) as Count_field1
  ,table2.fielda
  ,table2.fieldb
FROM
  table1
  INNER JOIN table2
    ON table1.field1 = table2.fieldc
WHERE
  table1.field2 in (@param1)
GROUP BY
  table2.fielda
  ,table2.fieldb
ORDER BY COUNT (table1.field1) DESC

我希望在WHERE子句中有另一个声明来排除或包含基于＆＃34;取消＆＃34;的记录。字段和用户选择的参数。所以，像这样：

SELECT TOP 10 COUNT (table1.field1) as Count_field1
  ,table2.fielda
  ,table2.fieldb
FROM
  table1
  INNER JOIN table2
    ON table1.field1 = table2.fieldc
WHERE
  table1.field2 in (@param1)
  IF (@includecancelled = TRUE, '', ',AND table1.cancelled = FALSE')
GROUP BY
  table2.fielda
  ,table2.fieldb
ORDER BY COUNT (table1.field1) DESC

这显然不起作用，但总体上是我想要的。

Answer 2

SELECT TOP 10 COUNT (table1.field1) as Count_field1
   ,table2.fielda
  ,table2.fieldb
FROM table1
  INNER JOIN table2
    ON table1.field1 = table2.fieldc
WHERE
  table1.field2 in (@param1)
  and ((  @includecancelled = TRUE  ) 
  OR  ( @includecancelled = FALSE AND table1.cancelled = FALSE ))
GROUP BY table2.fielda,table2.fieldb
ORDER BY COUNT (table1.field1) DESC
