Access SQL视图中出现语法错误
我总是在Access SQL方面遇到问题。该语法要求随机添加括号或移动与SQL Server不同的内容。有人知道这里可能有什么语法错误吗？错误集中在FROM子句周围。我知道其他条款还可以，但我把它们留了下来作为参考 更新：代码简化了很多。我主要关心的是FROM的3个从句Access SQL视图中出现语法错误,sql,ms-access,syntax,Sql,Ms Access,Syntax,我总是在Access SQL方面遇到问题。该语法要求随机添加括号或移动与SQL Server不同的内容。有人知道这里可能有什么语法错误吗？错误集中在FROM子句周围。我知道其他条款还可以，但我把它们留了下来作为参考 更新：代码简化了很多。我主要关心的是FROM的3个从句 SELECT ...

Access一次只能联接两个表。你需要很多括号。有趣的是，我不知道。Access一次只能连接两个表。你需要很多括号。很有趣，我不知道。是否有一种访问等价物，将一个字段上的两个表连接起来，并返回字段不匹配的行？是否有一种访问等价物，将一个字段上的两个表连接起来，并返回字段不匹配的行？如果我有两个内部连接和一个左连接怎么办？然后在字段周围放一对括号JOIN您希望首先执行，并且该结果将被联接到第三个表。我有点困惑。你是说从tbl1内部连接tbl2到。。。上的内部联接tbl3。。。左连接tbl4打开。。。或者你的意思是从tbl1内部连接到tbl2上。。。上的内部联接tbl3。。。左连接tbl4在？我用更简单的代码更新了我的问题，以便更好地显示我当前使用的括号。对不起，我误读了你的原始评论。我很快会更新我的答案。如果我有两个内部连接和一个左连接呢？然后你只需在你想首先执行的连接周围放一对括号，结果将被连接到第三个表。我有点困惑。你是说从tbl1内部连接tbl2到。。。上的内部联接tbl3。。。左连接tbl4打开。。。或者你的意思是从tbl1内部连接到tbl2上。。。上的内部联接tbl3。。。左连接tbl4在？我用更简单的代码更新了我的问题，以便更好地显示我当前使用的括号。对不起，我误读了你的原始评论。我很快会更新我的答案。
