我创建了一个新的 SQL web2py 数据库，如下所述......但是当我尝试保存它时，它给出了语法错误。我如何将它保存在 web2py 上并将其用于我的网页..

首先，表名和字段名必须是有效的 Python 标识符，因此它们不能包含空格。相反，如果您使用下划线，它们将自动转换为 SQLFORM 标签中的空格。Field()如果您不喜欢默认标签，您还可以为构造函数指定一个单独的“标签”参数来为表单和网格创建标签。

其次，字段类型应该是小写的，并且没有“varchar”字段类型——而是应该是“string”（虽然“string”是默认值，所以不是必需的）。

最后，SQLDB已弃用以支持DAL，并SQLField已被弃用以支持Field。

我强烈建议在继续之前阅读DAL文档。
