带空格的列名 - Athena

Question

I am trying to create a table that has a column name with Space using Athena Console.我正在尝试使用 Athena 控制台创建一个列名称为 Space 的表。

Example: "Mag Creative" String示例：“Mag Creative”字符串

Error: This field is required.错误：此字段是必需的。 Spaces are not allowed!不允许有空格！

Answer 1

你可以试试双引号，像这样：

SELECT i."interest expense" FROM "financial-analysis-tool"."income_statement"

Answer 2

Considering that Athena column names cannot contain any other special character besides underscore , the error is prescriptive and explicit about what the problem is.考虑到 Athena 列名不能包含除 underscore 之外的任何其他特殊字符，错误是关于问题是什么的规定性和明确的。 You must use an underscore for this column name instead.您必须对此列名称使用下划线。

Answer 3

It is not recommended to use a space in the name of a table column;不建议在表列名中使用空格； there are special rules for such cases.此类情况有特殊规则。
