将 T-SQL 左连接子查询转换为 MS-Access答案

【问题标题】：Converting T-SQL Left Join Subqueries to MS-Access将 T-SQL 左连接子查询转换为 MS-Access
【发布时间】：2012-07-27 02:40:09
【问题描述】：

我需要帮助来将此 T-SQL 查询转换为 MS ACCESS。我得到的错误是不支持 JOIN 表达式。

更新：

我无法添加：

DDA ON TT.[描述] = DDA.AccountTypeDesc AND H.AccountNumber = DDA.AccountNumber

但是

DDA ON TT.[描述] = DDA.AccountTypeDesc

有效。有没有办法添加第二个条件？

T-SQL 查询：

【问题讨论】：

我记得你应该在别名前写AS。
已更新，但即使我使用 AS 关键字也会返回相同的错误
也尝试使用AS 作为表别名。我看不出JOIN's 有任何问题
嗨，伊戈尔，我的具体问题。据我所知，我在所有表上都使用了别名，但它有一个错误。你能提供正确的查询吗？或者您可以提供带有子查询的连接吗？
当您遇到错误时，您是如何尝试运行该查询的？来自 Access 查询设计器或其他方法？

标签： sql-server tsql ms-access jet data-conversion

【解决方案1】：

放弃尝试将 SQL 文本从 T-SQL 查询转换到 Access SQL。从头开始创建新的 Access 查询并将 T-SQL 查询仅用作路线图。添加您的数据源并设置连接。查询设计器将保证您以使数据库引擎满意的方式创建连接：添加和定位具有多个连接的查询所需的括号；适用于 LEFT JOIN 的规则；等等。让设计师为您处理这些细节。

由于您上次加入的这部分中的功能，设计师将在设计视图中窒息：

RTRIM(TT.[Description]) = RTRIM(DDA.AccountTypeDesc)

因此，当您在设计视图中设置联接时，请忽略 RTRIM() 函数。不要担心查询不会返回正确的结果。获得满足 db 引擎的连接后，切换到 SQL 视图并重新添加 RTRIM() 函数。

正确设置连接后，将字段表达式添加到 SELECT 列表中。

此外，您可能会发现通过将子查询拆分为单独保存的查询来更轻松地管理您的复杂查询 --- 然后在主查询中按名称引用这些查询，就像您使用表源一样。

【讨论】：

更新：我无法添加：DDA ON TT.[Description] = DDA.AccountTypeDesc AND H.AccountNumber = DDA.AccountNumber 但 DDA ON TT.[Description] = DDA.AccountTypeDesc 有效。有没有办法添加第二个条件？
如果您在ON 子句中找不到使联接与AccountNumber 一起工作的方法，请将其移至最后的WHERE 子句：WHERE H.AccountNumber = DDA.AccountNumber 您可能需要添加@987654328 @

【解决方案2】：

问题出在倒数第二行：

  DDA ON RTRIM(TT.[Description]) = RTRIM(DDA.AccountTypeDesc) AND

Access 查询设计器的设计视图无法使用子句的ON 部分中的函数。您必须删除 RTRIM。

【讨论】：

@HansUp：你说得对。已更正。我把它和不允许的常量混在一起了（比如：... ON TT.Description = '123'）。
更新：我无法添加：DDA ON TT.[Description] = DDA.AccountTypeDesc AND H.AccountNumber = DDA.AccountNumber 但 DDA ON TT.[Description] = DDA.AccountTypeDesc 有效。有没有办法添加第二个条件？

【解决方案3】：

访问是愉快的括号。将每个连接表达式、ON 子句本身和每对表都括在括号中。

您不能使用 CONVERT、NOLOCK 或 CASE。

【解决方案4】：

您的系统中使用的是哪个版本的 MSAccess？我刚刚尝试了 2007 版本，RTRIM 正在工作。

我们使用的是同一版本：2007！
