HANA新手，为什么我的字段名需要被引用？
HANA Newbie, why do my field names need to be quoted?
我刚刚开始使用 SAP HANA - 试水。
我的第一步是在 Eclipse Luna 中打开一个 SQL 控制台，以便 运行 在 SAP Business One 演示数据库上进行简单查询。
我发现 "SELECT * FROM OCRD" 工作正常，但 "SELECT CardCode, CardName FROM OCRD" 导致无效字段错误。
在字段名称两边加上双引号会导致查询有效。
我有以下顾虑：
1) None 的 SAP HANA 示例表明查询中需要双引号。
2) 我们有大约 2000 行 T-SQL 查询要转换，如果我可以使用不带双引号的查询是最好的。
双引号是语法、JDBC、SAP B1、列存储还是 Eclipse？
如何运行查询而不需要这样的引号？
感谢您帮助我起床运行宁。

总的来说，你已经在评论中找到了答案。带引号的标识符区分大小写，不带引号的标识符不区分大小写 - 在某种程度上。不带引号的标识符基本上是 'converted' 到大写。所以
CREATE COLUMN TABLE tab (id INT);
和
CREATE COLUMN TABLE "TAB" ("ID" INT);
基本相同。反之亦然。所以
CREATE COLUMN TABLE "TAB" ("ID" INT);
SELECT id FROM tab;
SELECT Id FROM Tab;
SELECT "ID" FROM "TAB";
都可以，但是
SELECT "Id" FROM "Tab";
不会。所以总结一下：
是的，a_horse_with_no_name说的很对，带引号的标识符是区分大小写的。但是，当创建全部大写时，即使在引用时，您也不需要一直使用引号。
一个很好的提示可能是查看 HANA Studio 在显示结果时显示的列标题，它们会给你提示。如果它们都是大写的，那么列基本上是 case-insensitive 否则你必须用引号匹配确切的大小写。

总的来说，你已经在评论中找到了答案。带引号的标识符区分大小写，不带引号的标识符不区分大小写 - 在某种程度上。不带引号的标识符基本上是 'converted' 到大写。所以
CREATE COLUMN TABLE tab (id INT);
和
CREATE COLUMN TABLE "TAB" ("ID" INT);
基本相同。反之亦然。所以
CREATE COLUMN TABLE "TAB" ("ID" INT);
SELECT id FROM tab;
SELECT Id FROM Tab;
SELECT "ID" FROM "TAB";
都可以，但是
SELECT "Id" FROM "Tab";
不会。所以总结一下：
是的，a_horse_with_no_name说的很对，带引号的标识符是区分大小写的。但是，当创建全部大写时，即使在引用时，您也不需要一直使用引号。
一个很好的提示可能是查看 HANA Studio 在显示结果时显示的列标题，它们会给你提示。如果它们都是大写的，那么列基本上是 case-insensitive 否则你必须用引号匹配确切的大小写。
