Question

对于每个NAME，我要查询CALL_DATE的数据，该数据小于或等于START_DATE起的三个月。以下是我的尝试，但出现错误。

查询：

SELECT CALLER_NAME AS "NAME", 
       CAST(CREATED AS DATE) AS "CALL_DATE", 
       DURATION, 
       CAST(START_DATE AS DATE) AS "START_DATE"
FROM table1 
GROUP BY NAME
    HAVING CAST(CREATED AS DATE) >= MIN(CAST(START_DATE AS DATE)) AND CAST(CREATED AS DATE) <= DATEADD(MONTH, 3, CAST(START_DATE AS DATE))
ORDER BY AE_NAME, CALL_DATE

错误

信息8121，第16级，状态1，第12行   在HAVING子句中，“ CREATED”列无效，因为它不在聚合函数或GROUP BY子句中。

信息8121，级别16，状态1，第12行在以下位置无效：“ START_DATE”列   HAVING子句，因为它既不包含在任何聚合中   函数或GROUP BY子句。

我了解为什么会收到此错误，但我不知道如何解决。非常感谢您的帮助。

Answer 1

您需要按原始字段名称（而不是别名）进行分组。您还需要对所有未聚合的内容进行分组。

这应该有效：

SELECT CALLER_NAME AS "NAME", 
       CAST(CREATED AS DATE) AS "CALL_DATE", 
       DURATION, 
       CAST(START_DATE AS DATE) AS "START_DATE"
FROM table1 
GROUP BY  CALLER_NAME, CREATED, DURATION, START_DATE
    HAVING CAST(CREATED AS DATE) >= MIN(CAST(START_DATE AS DATE)) AND CAST(CREATED AS DATE) <= DATEADD(MONTH, 3, CAST(START_DATE AS DATE))
ORDER BY AE_NAME, CALL_DATE

Answer 2

在“分组依据”子句中添加“创建”和“ START_DATE”。

SELECT CALLER_NAME AS "NAME", 
       CAST(CREATED AS DATE) AS "CALL_DATE", 
       DURATION, 
       CAST(START_DATE AS DATE) AS "START_DATE"
FROM table1 
GROUP BY NAME, CREATED, START_DATE
    HAVING CAST(CREATED AS DATE) >= MIN(CAST(START_DATE AS DATE)) AND CAST(CREATED AS DATE) <= DATEADD(MONTH, 3, CAST(START_DATE AS DATE))
ORDER BY AE_NAME, CALL_DATE

或者使用WHERE而不是HAVING

SELECT CALLER_NAME AS "NAME", 
       CAST(CREATED AS DATE) AS "CALL_DATE", 
       DURATION, 
       CAST(START_DATE AS DATE) AS "START_DATE"
FROM table1 
GROUP BY NAME
    WHER CAST(CREATED AS DATE) >= MIN(CAST(START_DATE AS DATE)) AND CAST(CREATED AS DATE) <= DATEADD(MONTH, 3, CAST(START_DATE AS DATE))
ORDER BY AE_NAME, CALL_DATE

恐怕您必须通过从头开始重写来修复它。如错误所示，当您在一个或多个列上进行GROUP时，真正真正可以进行选择的唯一内容是GROUP BY子句中的那些列（或表达式），或者是聚合函数，在这种情况下，这些函数适用于ALL具有给定名称的行。

同时选择NAME和（例如）DURATION时，它不认为您想要与一个NAME位于同一行的DURATION值，而是所有功能中的某些函数（求和，最小值，最大值等） NAME旁边的DURATION。您不会在选择其他任何列的情况下执行此操作，无论是两个日期还是持续时间。

这很令人困惑，我在猜测您要做什么，这实际上不是每个NAME多行汇总报告。我认为，您希望每行具有NAME的行都输出，但是只需选择以下行：

1）CREATED是> =整个表中的最小START_DATE 2）创建时间是该行中START_DATE之后的三个月之内

唯一需要的汇总就是找到最小的START_DATE。最容易读取的代码是子查询。如果我猜对了，那么该代码将是（不确定您的SQL变体，我将尝试在CAST语法中使用cut＆paste）：

SELECT CALLER_NAME AS "NAME", 
       CAST(CREATED AS DATE) AS "CALL_DATE", 
       DURATION, 
       CAST(START_DATE AS DATE) AS "START_DATE"
FROM table1 
WHERE CAST(CREATED AS DATE) >= (SELECT MIN(CAST(START_DATE AS DATE)) FROM table1)
  AND CAST(CREATED AS DATE) <= DATEADD(MONTH, 3, CAST(START_DATE AS DATE));

SQL选择动态日期范围之间的行
