在我的 SQL 查询中使用“或”会导致 MS Access 2019 崩溃

Question

这是我关于 Stack 的第一个问题。 我是一名学生，试图通过实践来发展我的查询能力。 使用 Microsoft Access 和一些公开的人口普查数据（57,000 行的 5 个表），我遇到了以下问题。

当我尝试在“where”语句中使用“or”而不是“and”时，会导致 Access 停止响应。 为什么会这样？

例如，当我尝试更改时：

not MARRIAGE.P_TOT_MARRD_REG_MARRGE = 0 and not EDUCATION.INFANTS_PRIMARY_TOT_P = 0

对此：

not MARRIAGE.P_TOT_MARRD_REG_MARRGE = 0 or not EDUCATION.INFANTS_PRIMARY_TOT_P = 0

甚至对此：

not MARRIAGE.P_TOT_MARRD_REG_MARRGE = 0 or EDUCATION.INFANTS_PRIMARY_TOT_P = 0

它会导致崩溃。

这是因为我的语法错误吗？ 还是我误解了 Sequel 中“或”子句的应用？

我没有使用“或”的完整代码如下。

(
  select distinct top 10 
      CHILDREN.PK as top10Last10, 
      CHILDREN.TOTAL_TOTAL as children, 
      HOUSEHOLD.TOTAL_FAMHHOLD as familys, 
      FAMILY.INTCT_FAM_NO_OTR_CHLD_PRE_FAM as undivorced,

      not CHILDREN.TOTAL_TOTAL = 0 and

      MARRIAGE.P_TOT_MARRD_REG_MARRGE, 
      EDUCATION.INFANTS_PRIMARY_TOT_P
  from 
      CHILDREN, 
      HOUSEHOLD, 
      FAMILY, 
      MARRIAGE, 
      EDUCATION
  where 
      CHILDREN.PK = HOUSEHOLD.PK and 
      CHILDREN.PK = FAMILY.PK and 
      CHILDREN.PK = MARRIAGE.PK and 
      CHILDREN.PK = EDUCATION.PK and 
      not CHILDREN.TOTAL_TOTAL = 0 and
      not HOUSEHOLD.TOTAL_FAMHHOLD = 0 and
      not FAMILY.INTCT_FAM_NO_OTR_CHLD_PRE_FAM = 0 and
      not MARRIAGE.P_TOT_MARRD_REG_MARRGE = 0 and
      not EDUCATION.INFANTS_PRIMARY_TOT_P = 0
  order by 
      CHILDREN.TOTAL_TOTAL desc, 
      HOUSEHOLD.TOTAL_FAMHHOLD desc, 
      FAMILY.INTCT_FAM_NO_OTR_CHLD_PRE_FAM desc, 
      MARRIAGE.P_TOT_MARRD_REG_MARRGE desc, 
      EDUCATION.INFANTS_PRIMARY_TOT_P desc
);

这个完整的代码正在运行并返回我期望的表格。

提前感谢您的任何回复。

Answer 1

首先，不响应不是崩溃。

接下来，您可能需要更具体：

(not MARRIAGE.P_TOT_MARRD_REG_MARRGE = 0) or (not EDUCATION.INFANTS_PRIMARY_TOT_P = 0)

或者：

not (MARRIAGE.P_TOT_MARRD_REG_MARRGE = 0 or EDUCATION.INFANTS_PRIMARY_TOT_P = 0)

此外，请确保您在这些字段上有索引。
